FOUNDER’S JOURNAL / 毛发再生研究观察近五年毛发再生研究全景从“唤醒原有毛囊”到“构建新毛囊”
From Reactivating Existing Follicles to Engineering New Ones: A Five-Year View of Hair-Regeneration Research
HAIRMOZZ茂丝 × 前沿信号通路 × 微生态分型落地
范围 / Scope:2021—2026年9月。本文聚焦近五年毛囊再生领域的重要进展,区分疾病机制、信号通路、临床干预与组织工程等不同证据阶段。实验室或动物研究与人体临床结果分开讨论;HAIRMOZZ茂丝部分重点呈现 FCST™、NPTDT™、FMHT™、HMFRT™ 及 MAX / MORE / BASE / CARE 的技术逻辑与分型实践。
This article reviews major advances in hair-follicle regeneration from 2021 through September 2026, distinguishing among disease mechanisms, signaling pathways, clinical interventions, and tissue-engineering approaches at different stages of evidence. Laboratory and animal studies are discussed separately from human clinical outcomes. The HAIRMOZZ section focuses on the technical rationale and stratified application of FCST™, NPTDT™, FMHT™, and HMFRT™, together with the MAX / MORE / BASE / CARE system.摘要 / Takeaway
过去五年,毛发再生研究最重要的变化,是从“单一成分促生长”转向把毛囊理解为一个由上皮、真皮凝集体/毛乳头、免疫、脂肪组织、血管与代谢状态共同调控的微型器官。Wnt/β‑catenin、SHH、BMP、Notch 等网络参与毛囊发生与周期转换;AR–DHT 轴是雄激素性脱发(AGA)的核心病理轴之一,细胞因子–JAK 信号则与斑秃(AA)的免疫病理密切相关。距离临床应用最近的仍是“保护或重新激活现有毛囊 + 按病因干预”;真正从零构建能长期、定向、周期性生长的新毛囊,仍面临细胞来源、空间组织、血供整合、免疫与长期安全性等问题[1–3]。
Over the past five years, one of the most important shifts in hair-regeneration research has been the move away from a “single growth-promoting ingredient” model toward understanding the hair follicle as a mini-organ jointly regulated by epithelium, dermal condensates/dermal papillae, immune cells, adipose tissue, vasculature, and metabolic state. Wnt/β-catenin, SHH, BMP, and Notch signaling networks participate in follicle morphogenesis and hair-cycle transitions; the AR–DHT axis is a central pathological driver of androgenetic alopecia (AGA), whereas cytokine–JAK signaling is closely linked to the immune pathophysiology of alopecia areata (AA). The approaches closest to clinical practice remain preservation or reactivation of existing follicles together with cause-directed intervention. De novo generation of follicles capable of durable, oriented, cyclic growth still faces major challenges in cell sourcing, spatial organization, vascular integration, immune compatibility, and long-term safety[1–3].
在 HAIRMOZZ茂丝,我们没有把生发理解为“找到一条万能通路”。真正有效的毛囊管理,需要把毛囊活性、局部递送、头皮微生态和结构支持拆开判断,再重新组合成可检测、可分型、可复测的方案。FCST™(毛囊细胞信号传导)围绕与毛囊生长期相关的信号网络建立管理逻辑;NPTDT™(纳米多肽透皮递送)负责局部递送支持;FMHT™(毛囊微生态稳态)从油脂、屏障、头屑/炎症与微生态状态进行分型;HMFRT™(微纤维再生)聚焦 ECM、基底膜与结构支持。四类技术与 MAX / MORE / BASE / CARE 形成“检测 → 分型 → 针对性管理 → 复测”的闭环。
At HAIRMOZZ, we do not reduce hair regeneration to a single “universal” pathway. Effective follicular management requires separate assessment of follicular activity, local delivery, scalp microecology, and structural support, followed by integration into a plan that can be measured, stratified, and reassessed. FCST™ (follicular-cell signal transduction) organizes management around signaling networks associated with anagen; NPTDT™ (nano-peptide transdermal delivery) provides localized delivery support; FMHT™ (follicular microecology homeostasis) stratifies scalp status by sebum, barrier condition, dandruff/inflammation, and microecology; and HMFRT™ (microfibril regeneration) focuses on ECM, basement-membrane, and structural support. Together with MAX / MORE / BASE / CARE, these technologies form a closed loop of detection → stratification → targeted management → reassessment.一、先分清:让旧毛囊长发,还是生成新毛囊?
雄激素性脱发(AGA)的典型病理过程是现存毛囊逐步微型化、毛干变细及生长期缩短;斑秃(AA)则属于免疫介导的非瘢痕性脱发。让休眠或微型化的原有毛囊恢复产出、把已有毛囊移植到新的位置,以及在原本缺乏毛囊的区域从头形成完整的新毛囊,是三种不同的技术目标。当前成熟临床证据主要集中在前两类;第三类仍以机制、组织工程与临床前转化为主[1–3]。
Androgenetic alopecia (AGA) is typically characterized by progressive miniaturization of existing follicles, reduced hair-shaft caliber, and shortening of the anagen phase; alopecia areata (AA) is an immune-mediated, non-scarring form of hair loss. Reactivating dormant or miniaturized native follicles, transplanting existing follicles to a new site, and generating a complete new follicle de novo are three distinct technical goals. Mature clinical evidence currently centers on the first two, whereas de novo follicle generation remains largely within mechanistic research, tissue engineering, and preclinical translation[1–3].
真正进入方案前,第一步不是先讨论“能不能长”,而是确认毛囊单位是否仍然存在、是否以非瘢痕性微型化为主,以及是否伴随明显炎症、屏障受损或其他需要医学评估的信号。若毛囊口消失、出现瘢痕样改变、渗液/脓疱或快速进展,应优先进入皮肤科/毛发专科诊断路径。
Before any intervention is selected, the first question is not simply whether hair can grow back, but whether follicular units are still present, whether the dominant process is non-scarring miniaturization, and whether there is significant inflammation, barrier disruption, or another finding that warrants medical evaluation. Loss of follicular openings, scar-like change, exudation/pustules, or rapid progression should prompt dermatologic or hair-specialty evaluation first.二、毛囊不是单个开关:细胞 + 信号双层地图
在 HAIRMOZZ茂丝的研发与分型体系中,我们把毛囊关键细胞与现代信号网络放在同一张地图上理解:
Within the HAIRMOZZ research and stratification framework, we map the key follicular cell populations together with the modern signaling networks that regulate them:2.1 毛乳头细胞 DPCs|Dermal Papilla Cells
定位:位于毛球底部的特化间充质细胞群,是调控毛囊大小、周期与毛干形成的重要信号中心。
Location: a specialized mesenchymal cell population at the base of the hair bulb that serves as a major signaling center governing follicle size, cycling, and hair-shaft formation.
机制要点:从休止期进入生长期并非由 DPCs 单独“分泌某一种 Wnt”完成,而是多个细胞区室共同参与的 Wnt/BMP 等信号平衡。毛乳头可提供 FGF7/10、TGF‑β2、Noggin 等促激活线索,降低 BMP 相关静息阈值;其与上皮细胞、血管及周围基质的双向通讯共同决定毛囊是否进入新的生长期[1]。
Mechanistic point: the transition from telogen to anagen is not driven by dermal papilla cells simply “secreting one Wnt.” Rather, it reflects the coordinated balance of Wnt/BMP and other signals across multiple cellular compartments. The dermal papilla provides pro-activation cues including FGF7/10, TGF-β2, and Noggin, helping lower BMP-associated quiescence, while bidirectional communication with epithelial cells, vasculature, and the surrounding matrix contributes to anagen entry[1].2.2 毛囊干细胞 HFSCs|Hair Follicle Stem Cells
定位:主要位于毛囊隆突区(Bulge)及与毛胚/外根鞘相关的干细胞区室;K15、LGR5 等可作为不同亚群或阶段的常用标志物,但表达具有物种、区段与周期差异。
Location: primarily within the bulge and the stem/progenitor compartments associated with the hair germ and outer root sheath. K15, LGR5, and related markers identify different stem/progenitor subsets or stages, with expression varying by species, follicular region, and hair-cycle phase.
功能:HFSCs 在休止期维持相对静息,在合适的微环境信号下进入活化与分化。Wnt/β‑catenin 是生长期启动的重要轴,但必须与 BMP、SHH、Notch 等网络在正确的细胞、时间和空间中协同;简单“把 Wnt 调高”并不等于可以安全、持续地长出新毛囊[1,5]。
Function: HFSCs remain relatively quiescent during telogen and enter activation and differentiation in response to an appropriate niche. Wnt/β-catenin is a major axis for anagen initiation, but it must act in coordination with BMP, SHH, Notch, and other networks in the correct cells, at the correct time, and in the correct spatial context. Simply “turning up Wnt” does not equate to safe, durable de novo follicle formation[1,5].2.3 毛母质细胞|Matrix Cells
定位与功能:毛球部的快速增殖祖细胞群围绕毛乳头分布,在信号驱动下持续增殖并向上分化,形成内毛根鞘与毛干的不同层次。
Location and function: rapidly proliferating progenitor cells in the hair bulb surround the dermal papilla and, under niche-derived signals, continuously proliferate and differentiate upward to form the distinct layers of the inner root sheath and hair shaft.
角蛋白表达具有明确的区室差异:内毛根鞘常见 K25–28 与 K71–74;毛干则以 K31–40 与 K81–86 等毛发角蛋白为代表。毛母质增殖/分化异常或过度凋亡,可表现为毛干形成受损与直径下降。
Keratin expression is strongly compartment-specific: the inner root sheath commonly expresses K25–28 and K71–74, whereas the hair shaft is characterized by hair keratins including K31–40 and K81–86. Abnormal matrix-cell proliferation/differentiation or excessive apoptosis can impair shaft formation and reduce hair caliber.2.4 黑素细胞|Melanocytes
定位:生长期毛球的色素单位与毛母质细胞相邻;成熟黑素细胞合成真黑素/褐黑素并将黑素体转运至形成中的毛干。白发与黑素细胞干细胞耗竭、迁移/分化异常及氧化应激等多因素有关,不能简化为单一“黑素细胞衰退”。
Location: during anagen, the follicular pigmentary unit lies adjacent to matrix cells in the hair bulb. Mature melanocytes synthesize eumelanin and pheomelanin and transfer melanosomes into the developing hair shaft. Hair graying is multifactorial, involving melanocyte stem-cell depletion, altered migration/differentiation, oxidative stress, and other processes rather than a single mechanism of “melanocyte decline.”2.5 系统层四条轴|Systemic axes
系统层面可概括为:Wnt/β‑catenin 参与毛囊发生与生长期激活;SHH 参与形态发生、祖细胞扩增与上皮–间充质互作;BMP 在休止期有助维持静息,并在不同阶段参与分化;Notch 参与细胞命运与分化。AGA 还叠加 AR–DHT、TGF‑β 等病理轴;AA 则以免疫细胞因子–JAK 信号为重要通路[1,2,5]。
At the systems level, Wnt/β-catenin contributes to follicle morphogenesis and anagen activation; SHH participates in morphogenesis, progenitor expansion, and epithelial–mesenchymal interactions; BMP helps maintain quiescence during telogen while also contributing to stage-dependent differentiation; and Notch regulates cell fate and differentiation. AGA additionally involves pathological axes such as AR–DHT and TGF-β, whereas immune cytokine–JAK signaling is a major pathway in AA[1,2,5].2.6必须讲清楚的 HAIRMOZZ 与耶鲁故事:Wnt × SHH
耶鲁大学团队 2022 年发表于 Developmental Cell 的研究,利用单细胞测序、遗传扰动与计算分析,在小鼠胚胎皮肤中解析了 Wnt/β‑catenin 与 SHH 两种形态发生信号的时空交互如何推动 Dkk1 阳性前体走向真皮凝集体(dermal condensate),这一结构是后续毛乳头信号中心的重要前体。研究价值在于解释“诱导性真皮微环境如何被建立”,并为实验室重建毛囊提供生物学蓝图[5,6]。这也解释了为什么 HAIRMOZZ茂丝持续强调“信号网络 + 毛囊生态位”:毛囊进入新的生长周期,不是把某一条通路单独拉高,而是细胞身份、时空信号与局部微环境共同作用的结果。
A 2022 Developmental Cell study from a Yale team used single-cell sequencing, genetic perturbation, and computational analysis in mouse embryonic skin to show how the spatial and temporal interplay between Wnt/β-catenin and SHH drives Dkk1-positive progenitors toward a dermal condensate, an important precursor of the future dermal papilla signaling center. The study helps explain how an inductive dermal microenvironment is established and provides a biological blueprint for laboratory follicle reconstruction[5,6]. This also helps explain why HAIRMOZZ emphasizes “signaling networks + the follicular niche”: entry into a new growth cycle is not achieved by simply amplifying a single pathway, but by coordinated interactions among cell identity, spatial-temporal signaling, and the local microenvironment.
Yale Ventures 的 NuFoll 技术转化页面进一步提出,通过小分子作用于两个细胞靶点、重编程真皮细胞以形成真皮凝集体。公开页面仅以 “Target X / Target Y” 代称靶点,因此现阶段不能自行把二者等同于 Wnt 与 SHH;该项目目前仍处于临床前技术转化阶段[7]。
The Yale Ventures NuFoll technology-transfer page further proposes reprogramming dermal cells through small molecules acting on two cellular targets to promote dermal-condensate formation. The public page refers to these targets only as “Target X” and “Target Y”; at present, they should not be assumed to correspond to Wnt and SHH. The program remains at a preclinical translational stage[7].三、近五年四条技术链路:从信号到产品3.1 调控原有毛囊(最接近应用)
针对 AGA 病因轴的药物研发正在从传统受体阻断走向更精细的靶向机制。外用 AR 蛋白降解剂 GT20029 的多中心随机双盲Ⅱ期研究于 2025 年发表:180 名 Hamilton–Norwood IIIv–V 男性接受 12 周治疗,部分给药方案较安慰剂改善目标区域非毳毛计数,提示潜在疗效,但疗程、长期安全性及更广泛人群仍需进一步验证[4]。另一条路线是毛囊干细胞代谢调控:PP405 为局部 MPC 抑制剂,2025 年公司公布的Ⅱa期顶线结果显示主要安全终点达成,并出现早期探索性毛发密度信号;截至 2026 年仍属在研药物,后续晚期临床开发仍需正式数据验证[8,9]。两者的共同点是尝试恢复现有毛囊/毛囊单位功能,而不是证明可以“批量制造全新毛囊”。
Drug development targeting the pathogenic axis of AGA is moving beyond conventional receptor blockade toward more precise mechanisms. A multicenter, randomized, double-blind phase 2 study of the topical androgen-receptor (AR) degrader GT20029 was published in 2025: 180 men with Hamilton–Norwood IIIv–V AGA received 12 weeks of treatment, and selected dosing regimens improved target-area non-vellus hair counts versus placebo. The findings suggest potential efficacy, although treatment duration, long-term safety, and performance in broader populations require further validation[4]. A separate strategy targets hair-follicle stem-cell metabolism. PP405 is a topical mitochondrial pyruvate carrier (MPC) inhibitor; company-reported phase 2a topline results in 2025 met the primary safety endpoint and showed an early exploratory signal in hair density. As of 2026, PP405 remains investigational, and later-stage development still requires confirmation in complete clinical datasets[8,9]. Both approaches aim to restore function in existing follicles/follicular units rather than demonstrate the mass creation of entirely new follicles.3.2 调节微环境
富血小板血浆(PRP)、光生物调节(PBM)、细胞治疗及其分泌组/外泌体,都在尝试改变生长因子、炎症、代谢与细胞间通讯。近年综述显示:PRP 的临床研究数量最多,但制备、剂量和终点尚不统一;PBM 作为单药的证据仍受设备参数与研究异质性影响;干细胞与外泌体有早期临床信号,但标准化、安全性与监管证据仍不足。机械刺激及脂肪–毛囊代谢通讯同样是活跃研究方向,其中不少结果仍来自动物或机制研究,不能直接等同于成熟临床疗法[3,10,11]。
Platelet-rich plasma (PRP), photobiomodulation (PBM), cell-based therapies and their secretomes/exosomes all seek to modify growth-factor signaling, inflammation, metabolism, and intercellular communication. Recent reviews indicate that PRP has the largest clinical evidence base, but preparation methods, dosing, and endpoints remain heterogeneous; evidence for PBM as monotherapy is still affected by variation in device parameters and study design; and stem-cell/exosome approaches show early clinical signals but still lack robust standardization, safety, and regulatory evidence. Mechanical stimulation and adipose–follicle metabolic crosstalk are also active research areas, with many findings still derived from animal or mechanistic studies rather than established clinical therapy[3,10,11].3.3 构建新毛囊(机制与转化阶段)
真皮乳头/上皮细胞共培养、诱导多能干细胞(iPSC)来源组织、三维水凝胶支架与生物打印,核心目标都是重建毛囊发生所需的上皮–间充质空间关系。Kang 等的明胶–海藻酸盐 3D 生物打印研究(2022 年在线发表,2023 年正式刊载)在体外构建毛囊样结构,并在裸鼠创面模型观察到毛囊形成,但距离人类头皮上稳定、定向、长期循环生长仍有明显转化距离[12]。Kageyama 等 2026 年进一步使用人 iPSC 来源外胚层前体细胞,与小鼠胚胎间充质细胞共同形成嵌合毛囊类器官并观察到毛囊萌发;研究者也明确指出,仍需建立人源间充质层,才能迈向“全人源”毛囊类器官[13]。
Dermal-papilla/epithelial co-culture, induced-pluripotent-stem-cell (iPSC)-derived tissues, 3D hydrogel scaffolds, and bioprinting all aim to reconstruct the epithelial–mesenchymal spatial relationships required for follicle induction. A gelatin–alginate 3D bioprinting study by Kang et al. (published online in 2022 and in final issue form in 2023) generated follicle-like structures in vitro and observed follicle formation in a nude-mouse wound model, but substantial translational barriers remain before stable, oriented, long-term cyclic growth can be achieved on the human scalp[12]. In 2026, Kageyama et al. used human iPSC-derived ectodermal precursor cells together with mouse embryonic mesenchymal cells to generate chimeric hair-follicle organoids with follicular sprouting. The authors also noted that a human mesenchymal layer is still needed to move toward a fully human hair-follicle organoid system[13].3.4 按病因恢复毛发,而非混用“再生”概念
严重斑秃的 JAK 抑制剂已有随机Ⅲ期证据,例如巴瑞替尼在两项 BRAVE-AA 试验中改善了严重 AA 的头皮毛发再生结局[2]。其逻辑是抑制异常免疫信号,使仍存在的毛囊恢复生长,而不是“新造毛囊”;这类证据不能直接外推到 AGA。产后、快速减重、疾病/药物相关或压力诱发的休止期脱发,则应首先寻找和纠正诱因,并结合铁代谢、甲状腺、营养与其他必要检查进行评估;头皮护理可作为支持,但不能替代病因处理。
JAK inhibitors have randomized phase 3 evidence in severe alopecia areata; for example, baricitinib improved scalp-hair regrowth outcomes in the two BRAVE-AA trials[2]. Their therapeutic logic is to suppress abnormal immune signaling so that existing follicles can resume growth, rather than to create new follicles. This evidence should not be extrapolated directly to AGA. Postpartum, rapid-weight-loss, illness/medication-associated, or stress-induced telogen effluvium should first be evaluated for underlying triggers, with assessment of iron status, thyroid function, nutritional factors, and other indicated causes; scalp care may provide supportive management but does not replace treatment of the underlying cause.四、HAIRMOZZ茂丝:把“信号 + 微生态 + 结构 + 复测”变成可交付矩阵4.1 MAX 生发系统|信号唤醒
MAX 生发系统FCST™ 毛囊细胞信号传导以 Wnt/β‑catenin 为主,协同 PI3K/AKT 抗凋亡、MAPK、VEGF 微循环,面向 Norwood/Hamilton 3–7 级、遗传/雄脱/脂溢性、明显微小化;NPTDT™ 纳米多肽透皮把活性信号肽/蛋白送到毛乳头与隆突区,降低不必要的系统吸收。对应“DPCs 补 Wnt 类信号 → HFSCs 解休眠 → BMP/Noggin 再平衡”。
In the MAX Hair Growth System, FCST™ follicular-cell signal transduction centers on Wnt/β-catenin, with coordinated support from PI3K/AKT anti-apoptotic signaling, MAPK, and VEGF-mediated microcirculatory support. It is positioned for Norwood/Hamilton grades 3–7, hereditary/androgenetic or seborrheic-associated hair loss, and marked follicular miniaturization. NPTDT™ nano-peptide transdermal delivery is designed to deliver active signaling peptides/proteins to the dermal papilla and bulge regions while limiting unnecessary systemic exposure. Mechanistically, the framework can be summarized as: DPCs replenish Wnt-related signals → HFSCs exit dormancy → BMP/Noggin balance is restored.4.2 MORE 头皮抗衰系统|营养与结构支持
MORE 定位于头皮营养、紧致与年轻态管理,核心关注头皮 ECM、基底膜和胶原网络所形成的“结构性生态位”。其技术结构由 NPTDT™ + HMFRT™ 组成,通过结构蛋白与营养支持改善头皮力学环境与发根支撑感,适用于头皮松弛、发根支撑下降、轻度稀疏伴头皮老化表现等场景。核心目标是让头皮从“表面护理”进一步进入基底膜、胶原网络与组织力学层面的年轻态管理。
MORE is positioned for scalp nutrition, firmness, and skin-longevity management, with particular focus on the “structural niche” formed by the scalp ECM, basement membrane, and collagen network. Its technical framework combines NPTDT™ + HMFRT™, using structural-protein and nutritional support to improve the scalp’s mechanical environment and root support. It is designed for scalp laxity, reduced root support, and mild thinning associated with signs of scalp aging. The goal is to extend scalp care beyond surface maintenance toward longevity management at the level of the basement membrane, collagen network, and tissue mechanics.4.3 BASE 问题肌系统|屏障、油脂与微生态稳态
BASE 从油、屑、敏、红/炎等头皮问题切入,把微生物控制、蛋白酶炎症、氧化应激与屏障/基底膜支持放在同一套稳态逻辑中。它不是单纯“控油去屑”,而是针对头皮问题肌的多通路管理:一边降低异常微生物与蛋白酶负担,一边减轻炎症放大,同时为屏障与 ECM 稳态提供支持。
BASE addresses oily, flaky, sensitive, and erythematous/inflammatory scalp conditions within a single homeostatic framework that integrates microbial control, protease-driven inflammation, oxidative stress, and barrier/basement-membrane support. It is not simply an oil-control or anti-dandruff program; rather, it applies multi-pathway management to problem scalp by reducing excessive microbial and protease burden, dampening inflammatory amplification, and supporting barrier and ECM homeostasis in parallel.4.4 CARE 家居洗护|把专业管理延伸到日常
CARE 把机构方案延伸到每天的洗护场景。青蒿去屑、铁皮石斛维稳、巨藻控油、黑灵芝预洗、白藜芦醇舒缓喷雾等产品,分别承担清洁、去屑、控油、舒缓与发丝护理角色,让到店管理与居家护理保持同一方向。TRPV1/TRPA1、IL‑6/IL‑1β/TNF‑α 等机制研究可以帮助理解配方的舒缓逻辑,日常管理仍以头皮状态和复测变化作为判断依据。CARE 的价值,是减少护理断层,让 MAX / MORE / BASE 的管理逻辑可以延续到日常。
CARE extends professional in-clinic management into everyday hair and scalp care. Artemisia anti-dandruff, Dendrobium officinale maintenance, Macrocystis pyrifera oil-control, Ganoderma lucidum pre-wash, and resveratrol soothing products serve complementary roles in cleansing, dandruff control, sebum management, soothing, and hair-fiber care, helping keep home care aligned with the in-clinic plan. Mechanistic research involving TRPV1/TRPA1 and cytokines such as IL-6/IL-1β/TNF-α helps explain the soothing rationale of the formulations, while day-to-day management remains guided by scalp status and reassessment. CARE reduces gaps in maintenance and extends the management logic of MAX / MORE / BASE into daily routines.五、用户判断:先判断“哪条路径”,再决定“用什么项目”
发际线后移、头顶逐渐变细、病程超过数月并有家族史:先用毛发镜/标准化照片看密度、毛干直径差异、终毛/毳毛比例和毛囊口;若符合非瘢痕性 AGA/微型化特征,可在规范诊疗基础上评估 MAX 作为毛囊活性管理路径,伴油屑敏感时再叠加 BASE。若出现毛囊口消失或疑似瘢痕,不以 MORE “抗纤维化”,而应先转皮肤科明确诊断。
For a receding hairline or progressive crown thinning over several months, especially with a positive family history, first assess hair density, shaft-caliber variability, terminal/vellus ratio, and follicular openings using trichoscopy and standardized photography. If the findings are consistent with non-scarring AGA/follicular miniaturization, MAX may be evaluated as a follicular-activity management pathway alongside standard medical care, with BASE added when oily, flaky, or sensitive scalp features coexist. Loss of follicular openings or suspected scarring should prompt dermatologic diagnosis rather than positioning MORE as an “anti-fibrosis” treatment.
产后、快速减重、熬夜/高压后突然弥漫性掉发:先问时间线与诱因,并根据情况评估血常规、铁蛋白/铁代谢、甲状腺及营养状态等;在排除需要医学处理的原因后,MORE 可承担营养与头皮状态支持,BASE 用于伴随的屏障/油脂问题,CARE 负责居家连续性。
For sudden diffuse shedding after childbirth, rapid weight loss, sleep deprivation, or major stress, establish the timeline and likely trigger first, and assess CBC, ferritin/iron status, thyroid function, and nutritional status when indicated. Once causes requiring medical management have been excluded or addressed, MORE can provide nutritional and scalp-condition support, BASE can address accompanying barrier/sebum issues, and CARE can maintain continuity at home.
片状突发脱发、感叹号发、甲凹,或伴其他自身免疫线索:优先按斑秃路径转皮肤科评估。JAK 抑制剂属于处方治疗,不属于一般养护项目,也不能把斑秃的 JAK 证据套用到 AGA。
Sudden patchy hair loss, exclamation-mark hairs, nail pitting, or other autoimmune clues should prompt dermatologic evaluation for alopecia areata. JAK inhibitors are prescription therapies rather than routine scalp-care interventions, and evidence from AA should not be applied directly to AGA.
油、黄屑、痒、红,且普通去屑洗发越洗越刺激:先区分脂溢性皮炎、接触性刺激/过敏、银屑病等可能性。轻度且无警示信号时,可按 BASE 的“油脂 + 屏障 + 炎症”逻辑做辅助管理;若持续、反复、范围扩大,或出现渗液/脓疱/明显脱发,应转医生。
An oily scalp with yellow scale, itch, or erythema that becomes more irritated with conventional anti-dandruff shampoo should be differentiated from conditions such as seborrheic dermatitis, irritant/allergic contact dermatitis, and psoriasis. Mild presentations without red flags may receive adjunctive management under the BASE framework of “sebum + barrier + inflammation”; persistent, recurrent, or expanding disease, or the presence of exudation, pustules, or marked hair loss, warrants medical evaluation.
长期光滑发亮、毛囊口明显缺失或多年稳定性秃发:应如实说明,现有养护主要针对仍存在且具有生物学活性的原生毛囊;疑似瘢痕性脱发需医学诊断,适合植发与否也需专科评估。“从零再造可长期循环的人类新毛囊”目前仍属于研究与转化阶段。
For long-standing, smooth, shiny bald areas with obvious loss of follicular openings or years of stable alopecia, it should be made clear that current supportive care primarily targets native follicles that remain biologically viable. Suspected scarring alopecia requires medical diagnosis, and suitability for hair transplantation also requires specialist assessment. De novo generation of durable, cyclic human hair follicles remains a research and translational objective.六、从研究到实践:HAIRMOZZ茂丝五步分型 SOP
近五年前沿研究真正有价值的,不是多记几个“新药名词”,而是把毛囊问题转化为“病因识别 + 毛囊活性/信号 + 屏障/微生态 + 结构支持 + 客观复测”的分层管理。在 HAIRMOZZ茂丝,我们把这套逻辑落成五步:
The real value of recent hair-regeneration research is not in accumulating new-drug terminology, but in translating follicular problems into layered management: etiologic identification + follicular activity/signaling + barrier/microecology + structural support + objective reassessment. At HAIRMOZZ, we operationalize this framework in five steps:Step 1 检测分型 / Stratified detection
AI 毛发镜读毛干直径、终毛/毳毛比、毛囊开口、生长期占比;头皮端做油/干/屑/炎四分。必要时按微生态 SOP 采样:采样前48小时不洗头,以顶点病损与枕部对照做菌群拭子,报告丙酸杆菌、表皮葡萄球菌、马拉色菌丰度,并配 TEWL 与 pH 综合判稳态,不单看某一个菌。
AI-assisted trichoscopy is used to assess hair-shaft caliber, terminal/vellus ratio, follicular openings, and anagen proportion, while the scalp is stratified by oiliness/dryness, dandruff, and inflammation. When microecology sampling is indicated, follow the SOP: no hair washing for 48 hours before sampling; collect swabs from the affected vertex area and an occipital control site; report the abundance of C. acnes, S. epidermidis, and Malassezia; and interpret these findings together with TEWL and pH rather than targeting any single organism in isolation.Step 2 病因定主轴 / Etiology-led plan
AGA 先完成规范分型与病因评估,再决定是否进入 MAX/FCST™ 为核心的毛囊活性管理;NPTDT™ 负责局部递送支持。MAX 同时可用于植发后快速生长支持,在移植区稳定后围绕毛囊活性、营养与局部环境进行协同管理。涉及非那雄胺/度他雄胺等抗雄激素药物、米诺地尔或其他处方路径,由医生基于性别、年龄、风险与禁忌证评估。若伴明显油脂、红、屑或屏障问题,可先或同步进入 BASE 管理。活动期 AA 转皮肤科,休止期脱发先处理诱因。
For AGA, complete appropriate classification and etiologic assessment before considering MAX/FCST™-centered follicular-activity management; NPTDT™ provides local delivery support. MAX can also support faster post-transplant growth once the transplant area is stable, coordinating follicular activity, nutrition and the local environment. Anti-androgen drugs such as finasteride/dutasteride, minoxidil and other prescription pathways require physician assessment. If marked sebum, erythema, scale or barrier problems coexist, BASE can be introduced first or in parallel. Active AA requires dermatology evaluation, while telogen effluvium requires trigger management first.Step 3 结构修复并行 / Structural repair in parallel
对于头皮老化感、发根支撑下降、轻度稀疏伴营养/结构需求,可评估 MORE/HMFRT™ 作为头皮抗衰与结构支持模块。其重点是 ECM、基底膜与胶原网络所形成的结构性生态位,通过结构与营养双向支持改善头皮力学环境。若出现进行性毛囊口消失、明显瘢痕样白区或疼痛/脓疱,应先排除瘢痕性脱发。
For scalp-aging features, reduced root support, or mild thinning accompanied by nutritional/structural needs, MORE/HMFRT™ may be considered as a scalp anti-aging and structural-support module. Its focus is the structural niche formed by the ECM, basement membrane, and collagen network, using coordinated structural and nutritional support to improve the scalp’s mechanical environment. Progressive loss of follicular openings, obvious scar-like white areas, pain, or pustules should prompt evaluation for scarring alopecia before proceeding.Step 4 在研前沿:明确证据阶段 / Pipeline: define the evidence stage
GT20029、PP405 重点看靶点、试验阶段与已公开结果;其中 PP405 的Ⅱa期结果目前主要来自企业公开资料,完整同行评议数据仍需继续关注。PRP/PBM、外泌体/MSC、3D 生物打印和类器官则分别处于不同的临床或转化阶段。理解这些方向,是为了看清毛囊再生下一步会往哪里走;而 HAIRMOZZ茂丝当前的落地重点,仍是现存毛囊的分型管理、头皮环境管理与客观复测。
For GT20029 and PP405, the priority is to follow the biological target, trial stage, and publicly available results. Current phase 2a findings for PP405 are derived mainly from company disclosures, and complete peer-reviewed data remain important to watch. PRP/PBM, exosomes/MSC, 3D bioprinting, and organoids are at different clinical or translational stages. Understanding these directions helps clarify where hair-regeneration science may go next; HAIRMOZZ’s current practice focus remains stratified management of existing follicles, management of the scalp environment, and objective reassessment.Step 5 复测替代感觉 / Reassessment over impression
8–12 周可复评油脂、瘙痒、鳞屑、红斑、日常掉发趋势与依从性;毛发密度、毛干直径和终毛比例等生长指标更适合在约 24 周或更长周期、同一拍摄区域与光线条件下比较。对无毛囊口、疑似瘢痕或治疗反应明显不符合预期者及时升级检查或转诊。统一话术可改为:“先判断毛囊还在不在、主要是哪一种脱发,再看信号、头皮环境和结构支持;能客观复测的才进入方案,需要医学处理的及时转诊。”
At 8–12 weeks, reassess sebum, pruritus, scaling, erythema, day-to-day shedding trends, and adherence. Growth-related metrics such as hair density, shaft caliber, and terminal-hair proportion are better compared at around 24 weeks or later, using the same scalp area and standardized lighting/imaging conditions. Absence of follicular openings, suspected scarring, or a response that is clearly inconsistent with expectations should trigger further evaluation or referral. A practical standard statement is: “First determine whether the follicle is still present and identify the dominant type of hair loss; then assess signaling, the scalp environment, and structural support. Only objectively measurable targets should enter the management plan, and conditions requiring medical treatment should be referred promptly.”七、结语 / Conclusion
过去五年最重要的变化,是毛囊再生从“找一个促生长成分”进入“细胞 + 信号 + 生态位 + 代谢 + 组织工程”的系统阶段。距离临床最近的,仍是保护、恢复或重新激活已有毛囊,并按 AGA、AA、休止期脱发等不同病因管理;真正从零构建能长期循环的人类新毛囊,还要跨越细胞来源、空间定向、血供、免疫、神经整合与长期安全性等多重门槛。耶鲁 Wnt–SHH 工作把“诱导性真皮微环境如何建立”进一步拆解为可研究的细胞与时空信号问题,也让“如何构建新毛囊”这件事有了更清晰的生物学路径[5,6,12,13]。
The most important change over the past five years is that hair-regeneration research has moved from “finding one growth-promoting ingredient” into a systems era of cells + signaling + niche + metabolism + tissue engineering. The approaches closest to clinical practice remain preservation, recovery, or reactivation of existing follicles, with management tailored to different causes such as AGA, AA, and telogen effluvium. De novo engineering of human follicles capable of durable cyclic growth still has to overcome multiple barriers, including cell sourcing, spatial orientation, vascularization, immune and neural integration, and long-term safety. Yale’s Wnt–SHH work further breaks down the question of “how an inductive dermal microenvironment is established” into experimentally tractable cellular and spatial-temporal signaling problems, providing a clearer biological path for studying how new follicles might ultimately be constructed[5,6,12,13].
HAIRMOZZ茂丝的差异化,不是追着每一个新名词走,而是把毛囊看成一个需要同时管理信号、递送、微生态和结构支持的系统。FCST™ 管毛囊活性与信号逻辑,NPTDT™ 管局部递送支持,FMHT™ 管屏障、油脂与微生态,HMFRT™ 管营养与结构支持,再由 MAX / MORE / BASE / CARE 对应不同管理场景。最后用检测与复测回答最重要的问题:毛囊和头皮状态,是否正在沿预期方向变化。
这也是专业毛发管理真正重要的地方:不是把所有脱发都解释成同一条通路,而是先分清病因、判断毛囊是否仍有生物学活性,再决定该管信号、管环境、管结构,还是进入医学诊疗路径。
HAIRMOZZ is differentiated not by chasing every new term in hair science, but by treating the follicle as a system that requires coordinated management of signaling, delivery, microecology, and structural support. FCST™ addresses follicular activity and signaling logic; NPTDT™ provides local delivery support; FMHT™ addresses barrier status, sebum, and microecology; and HMFRT™ supports nutrition and structure. MAX / MORE / BASE / CARE then map these dimensions to different management scenarios. Detection and reassessment answer the most important practical question: are the follicle and scalp moving in the intended direction? This is also the core of professional hair management—not forcing every type of hair loss into a single pathway, but first identifying the cause and determining whether the follicle remains biologically active, then deciding whether the priority is signaling, the scalp environment, structural support, or medical diagnosis and treatment.声明 / Compliance note
