This review discusses the book "Hair Transplantation: The Art of Follicular Unit Micrografting and Minigrafting" by Drs. Barrera and Uebel, which comprehensively covers techniques and advances in modern hair restoration.

This review discusses recent Japanese research on trichotillomania and compares it with international studies, reporting no new clinical results.

Hair growth is cyclic and influenced mainly by local factors.

This article discusses the treatment of androgenetic alopecia and alopecia areata with finasteride and minoxidil but reports no new clinical results.

This article discusses evaluation and treatment options for a 19-year-old woman with slowly progressive hair growth and reports no new clinical findings.

In this study, tofacitinib was reported to improve scalp hair regrowth in patients with severe alopecia areata, alopecia totalis, and alopecia universalis, showing a higher response in alopecia areata.

This review discusses common hair loss conditions and explores how advancements in hair follicle biology might lead to more effective treatments but reports no new results.

This study found that dermal papilla cells from balding scalp hair follicles have significantly higher levels of androgen receptors than those from non-balding follicles, supporting their in vivo androgen response.

In this study, researchers identified 18 genetic associations with scalp and facial hair traits in Latin Americans, including novel loci for hair greying and balding, with implications for understanding hair evolution.

This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.

This review explores the causes and mechanisms of alopecia areata and discusses current treatments, reporting no new clinical findings.

This review discusses nonclassical 21-hydroxylase deficiency as the most common autosomal recessive disorder in humans and highlights the effectiveness of glucocorticoid treatment in reversing related symptoms.

In this retrospective cohort study, women with polycystic ovary syndrome showed high incidence and age-specific prevalence rates of type 2 diabetes, myocardial infarction, and angina, particularly in those over 65.

In this retrospective review, tofacitinib treatment was associated with clinically significant hair regrowth in most adolescent patients with alopecia areata, though limitations suggest further studies are needed to confirm these findings.

This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.

This review discusses the advancements in understanding and treating androgenetic alopecia and alopecia areata but reports no clinical findings; the authors emphasize the need for further research on molecular control mechanisms.

This study found that young indigenous South Asian women with polycystic ovary syndrome are more likely to be centrally obese and have metabolic syndrome, particularly with increasing age, higher BMI, and acanthosis nigricans.

This study found that adding platelet-rich plasma to microneedling improved outcomes for atrophic acne scars more than microneedling alone, according to both quantitative and qualitative assessments.

This review noted that alopecia areata is an autoimmune disease impacting hair follicles and offered insights into its complex pathogenesis involving immune responses, while highlighting ongoing research into new treatments such as Janus kinase inhibitors and other immunomodulatory drugs.

This article reviews recent updates on alopecia areata, focusing on its causes, clinical presentation, and treatment options, and provides treatment plans by patient age and disease extent, but reports no new clinical results.

Sericin hydrogels heal skin wounds well, regrowing hair and glands with less scarring.

This study found that premature hair loss due to stress does not occur in NK-1 receptor knockout or mast cell deficient mice, suggesting a key role for neurokinin substance P and mast cell interaction in stress-related hair follicle changes.

This review explores how androgens and growth hormone influence the development of terminal hairs and sebaceous glands, attributing variability in hirsutism and acne to differing genetic sensitivities to androgens, but reports no new experimental data.

This study found that 1-year use of 5alpha-reductase inhibitors, dutasteride or finasteride, significantly lowered dihydrotestosterone levels without adversely affecting bone density, lipids, or hemoglobin in normal men.

This study explored the interaction between androgen and Wnt signaling in dermal papilla cells, targeting the effects of androgen on hair growth reduction.

Vitiligo causes white skin patches and is linked to autoimmune issues.

This review discusses the complex interaction between androgens and hair follicle biology, highlighting the need for a better understanding to improve hirsutism treatments, but reports no new results.

This case report describes a patient with complete androgen insensitivity syndrome experiencing female pattern hair loss, suggesting that factors beyond direct androgen action may contribute to this condition in women.

This article presents two cases of keratosis follicularis spinulosa decalvans and reviews its features, highlighting characteristic progression from keratosis pilaris in infancy to cicatricial alopecia in childhood.
