This review discusses the roles of androgens and estrogens in skin functions and disorders, and highlights the use of estrogen-progestin treatments and anti-androgens in managing hirsutism and acne, without reporting new results.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This abstract reviews the characteristics and health risks associated with polycystic ovary syndrome and does not report new findings, highlighting the syndrome's multifactorial nature.

This review discusses the dermoscopic features of common hair and scalp disorders and reports no new clinical results, aiming to assist dermatologists in diagnosing conditions like tinea capitis and alopecia areata.

This review examines the direct-to-consumer genetic testing market, highlighting the available tests, regulatory issues, and calls for increased oversight, and reports no new results.

This article proposes five different mechanisms for telogen effluvium, supported by clinical findings, based on changes in different phases of the hair cycle.

This review summarizes recent advancements in follicular targeting for drug delivery via hair follicles and calls for pilot studies in humans to explore potential clinical applications.

This review discusses the role of androgens in hair follicle regulation and suggests that a better understanding could enhance treatments for conditions like hirsutism and alopecia, but does not present new findings.

This study describes a system for generating hair follicles from dissociated cells in mice, suggesting that successful development requires a foundational epithelial platform.

This review discusses the diagnosis and treatment of hirsutism, emphasizing that a systematic evaluation can determine its cause, while combination therapy effectively manages the condition for most patients.

This study demonstrates the potential of using bioengineered follicles from adult tissue-derived stem cells for fully functional hair regeneration, illustrating possible applications in organ replacement therapy.

This article discusses advancements in understanding how skin stem cells and fibroblasts contribute to scar formation, highlighting current and potential therapies aimed at preventing or reducing scarring, yet notes that effective treatments without significant side effects are still lacking.

In this study, cross-sex hormone therapy affected hair growth patterns differently, with estrogen reducing hair growth in male-to-female transsexuals and testosterone increasing it in female-to-male transsexuals; however, male typical hair diameters were not fully reached in the latter group after 12 months.

This study found that oral isotretinoin achieved good to excellent clinical results in treating severe inflammatory acne, severe rosacea, and gram-negative folliculitis.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This study found that telocytes are present in the human dermis, suggesting a potential role in skin homeostasis, remodeling, regeneration, and repair.

Androgens can cause hair growth in some areas and hair loss on the scalp.

This review discusses the pathogenesis and challenges in treating primary cicatricial alopecia, highlighting the need to understand immune protection collapse in hair follicle stem cells; it reports no new clinical results.

This study found that Smad7 perturbs hair follicle development while promoting sebaceous gland formation by antagonizing Wnt/β-catenin signaling in transgenic mice.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.
