Cold waving solutions quickly reduce cystine to cysteine in hair.

This study highlights the significant psychological impact of alopecia areata, emphasizing the reciprocal relationship between the disorder and psychiatric issues, and underscores the importance of identifying patients needing additional psychological support, especially women, young individuals, and those with severe alopecia or previous psychiatric history.

This review discusses recent findings on the epigenetic regulation of adult stem cells and cancer stem cells, highlighting shared and distinct features, and reports no new clinical results.

This study found that EDA and EDAR are expressed throughout cashmere goat fetal development and play a critical role in hair follicle formation by influencing gene expression in fibroblasts and epithelial cells.

This study observed that dandruff in Indian women is associated with a distinct scalp microbiome, including specific bacterial and unknown Malassezia species, with implications for nutrient homeostasis and cell-host adhesion pathways.

This study found that S-Methylmethionine sulfonium (SMMS) enhances cell survival and reduces damage from UVB irradiation in skin cells, suggesting its potential as a cosmetic ingredient for UV protection.

This study found that a newly constructed composite hydrogel dressing, made from silk fibroin, chitosan, and halloysite, promoted hair follicle neogenesis, angiogenesis tissue regeneration, and scar reduction.

This article discusses various types of alopecia more common in African-American individuals and reports no clinical results; it highlights the importance of recognizing and differentiating these subtypes for diagnosis and treatment.

In this study, a mixed-methods survey of 357 balding men revealed that baldness is structurally stigmatized, with many participants experiencing distress and using treatments to combat it; others resisted stigma and expressed minimal distress.

Older East and Southeast Asian men need less hair density for hair restoration satisfaction, and natural hairline features should guide surgery plans.

Certain skin drugs and topical agents, including some natural extracts and fragrances, can cause allergic reactions. Some hair dyes and extensions, as well as minoxidil, a hair growth treatment, can also cause allergies. Botulinum toxin A can effectively reduce sweat but may have temporary side effects.

This review discusses the significant burden of disease and psychosocial implications associated with alopecia, highlighting its comorbidities and the impact on quality of life despite being viewed traditionally as an aesthetic concern, but reports no clinical results.
