Premature Graying of Hair: A Comprehensive Review and Recent Insights

Review

作者: Bhalla, Mala ; Poonia, Kavita

AbstractBackground:Hair symbolizes well-being and self-expression, with graying occurring naturally among different racial groups at varying ages. Premature graying has psychological and societal impacts, influencing self-esteem and quality of life. Gray hair usually advances gradually and is permanent, with occasional reports of natural repigmentation. Premature graying of hair (PMGH) results from a complex interplay of genetic, environmental, and cellular factors.Materials and Methods:Studies exploring links between gray hair and conditions such as osteopenia, hearing loss, smoking, obesity, dyslipidemia, and cardiovascular disease have yielded mixed results. Despite continuous research into the causes of gray hair, effective, evidence-based treatments are lacking and still need to be improved.Conclusion:Herein, we reviewed the causes, mechanisms, risk factors, psychosocial effects, and emerging therapies for PMGH.

SASH1 S519N Variant Links Skin Hyperpigmentation and Premature Hair Graying to Dysfunction of Melanocyte Lineage

Article

A better understanding of human melanocyte (MC) and MC stem cell biology is essential for treating MC-related diseases. This study employed an inherited pigmentation disorder carrying the SASH1^S519N variant in a Hispanic family to investigate SASH1 function in the MC lineage and the underlying mechanism for this disorder. We used a multidisciplinary approach, including clinical examinations, human cell assays, yeast 2-hybrid screening, and biochemical techniques. Results linked early hair graying to the SASH1^S519N variant, a previously unrecognized clinical phenotype in hyperpigmentation disorders. In vitro, we identified SASH1 as a regulator in MC stem cell maintenance and discovered that TNKS2 is crucial for SASH1's role. In addition, the S519N variant is located in one of multiple tankyrase-binding motifs and alters the binding kinetics and affinity of the interaction. In summary, this disorder links both gain and loss of pigmentation in the same individual, hinting to accelerated aging in human MC stem cells. The findings offer insights into the roles of SASH1 and TNKS2 in MC stem cell maintenance and the molecular mechanisms of pigmentation disorders. We propose that a comprehensive clinical evaluation of patients with MC-related disorders should include an assessment and history of hair pigmentation loss.

Fractal Pattern in the Premature Graying of Hair: A Case Report

Article

作者: Rashid, Rashid M ; Niazi, Maryam ; Kashyap, Alisha ; Black, Troy A ; Ali, Amna M ; Phan, Brandy

Premature graying of hair (PGH) is a multifactorial condition defined by the graying of hair before the age of 20 in Caucasians and before the age of 30 in African Americans. Although the etiology remains unknown, it has been associated with genetic predisposition, oxidative stress, nutritional deficiencies, and autoimmune diseases. Current treatment options are limited but can include anti-inflammatory medications, vitamins, and hair colorants for symptom control. In this report, we present a case of premature graying in a 32-year-old male, onset at age 15, exhibiting a distinctive fractal pattern. This case represents a unique instance of PGH characterized by an unusual pattern, necessitating further investigation into potential etiological factors and underlying pathophysiological mechanisms.
