This review discusses the physiopathology of androgenetic alopecia and evaluates various traditional and emerging treatments, reporting no new clinical results but highlighting the need for enhanced treatment strategies.

This study found that 12 weeks of melatonin supplementation improved mental health and metabolic parameters in women with polycystic ovary syndrome compared to a placebo.

This study demonstrated a method for large-scale preparation of self-sorted hair follicle germs in vitro, which successfully generated hair follicles when transplanted into the skin of nude mice.

Hair transplantation successfully treated a woman's hair loss caused by a tight ponytail.

This study reviewed the role of the JAK/STAT signaling pathway in skin diseases and the potential of JAK inhibitors for treating conditions like psoriasis and atopic dermatitis. Although the findings are promising, the authors concluded it is premature to establish their place in dermatological treatments.

In this study, individuals reported a decrease in dermatologist visits for hair and scalp conditions like telogen effluvium and alopecia areata during COVID-19 quarantine, despite increased occurrences.

In this study, the RADA-PRG hydrogel enhanced SKP proliferation, survival, and gene expression, effectively supporting hair follicle regeneration in mice.

In this study, researchers found that eccrine sweat glands in human scalp skin are morphologically integrated into the pilosebaceous unit, suggesting they form a common homeostatic tissue environment with adjacent structures.

This article reviews the role of vasoactive intestinal peptide in maintaining immune privilege in hair follicles and does not report new findings; the authors propose it as essential for immune homeostasis in alopecia areata.

This study found that human hair follicle dermal cells, specifically dermal sheath cells, can serve as an alternative and potentially superior cell source for constructing the dermal component of bioengineered skin in both in vitro and in vivo settings.

This study found that pharmacological inhibition of sex steroid synthesis impacts pathogenic processes in traumatic brain injury in a sex-specific manner, with distinct effects of letrozole and finasteride on molecular and neurological outcomes.

This study found that STAT5 activation in the dermal papilla acts as a key switch to trigger anagen entry in postdevelopmental hair follicle cycling.

This study found that collagen VI influences hair follicle growth and wound-induced regrowth by activating the Wnt/β-catenin signaling pathway in mice, suggesting potential therapeutic targets for hair loss.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

This review reports no new clinical results but discusses fibrosing alopecia in a pattern distribution as a distinct scarring alopecia with characteristics of both androgenetic alopecia and lichen planopilaris.

This study found that trichoscopic examination is useful for diagnosing and monitoring systemic lupus erythematosus, with severe diffuse non-scarring alopecia indicating active disease.

This study found that combining microneedle treatments with 5% minoxidil topical solution led to the greatest increase in hair density among Chinese men with androgenetic alopecia.

This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

This study found that improved outcomes in scalp surgery were achieved by utilizing knowledge of the surgical anatomy of the scalp to avoid complications like unsightly scars and distorted hair patterns.

This study found that the acceleration of endothelial to mesenchymal transition due to loss of Notch signaling led to delayed wound healing and increased scarring in skin wounds.

In this study, loss of epidermal Par3 in mice disrupted the skin barrier and affected cell differentiation and stem cell maintenance, highlighting its role in epidermal homeostasis.

This case report describes an adolescent girl with polycystic ovarian syndrome and endogenously elevated androgen levels who developed a hepatic adenoma, suggesting a link between the two conditions.

This review discusses the role of cholesterol homeostasis in hair follicle biology and its potential connections to various hair disorders, but it reports no new findings.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.

This review found that the current evidence on using platelet rich plasma to treat non-cicatricial alopecia, such as androgenetic alopecia and alopecia areata, is of low quality and yields controversial results.

This study found various ABC transporters are transcribed in human hair follicles, suggesting their possible role in HF biology and potential for new therapeutic interventions.

This article reviews the roles of lesser-known secreted phospholipase A2 isoforms in various biological processes, such as immune suppression, metabolic regulation, epidermal hyperplasia, and male reproduction, without reporting new clinical findings.

This article reviews insights into the pathogenesis of primary cicatricial alopecias, such as lichen planopilaris, provided by emerging technologies, but it does not report new clinical results.

This study suggests that acne is often associated with hyperandrogenemia in women, contradicting previous recommendations that acne is not linked to androgen excess disorders.
