This abstract describes a diagnostic case of a 37-year-old woman with an erythematous scalp plaque and unexplained hair loss, without concluding which condition it represents.

This study found that in men with benign prostatic hyperplasia, a 3-month treatment with a long-acting GnRH agonist significantly reduced intraprostatic DHT and 3α-diol levels by about 90% and testosterone by about 75%.

This study found that minoxidil 2% increased nonvellus hair counts in women with female androgenetic alopecia without causing serious side effects, compared to a placebo.

This paper highlights that traction alopecia is common among certain ethnic groups and occupations due to tight hairstyling practices, but early-stage hair loss can often be reversed with treatment and by avoiding these styling habits, as observed in Hispanic and Black women.

In this case report, researchers diagnosed a 12-year-old girl with a nevus sebaceus of Jadassohn, characterized by a yellowish-pink plaque on the scalp and a genetic variant, following previous misdiagnosis as alopecia areata.

This case report diagnosed an 8-year-old girl with trachyonychia and secondary onychomycosis, finding that spontaneous improvement is common, making specific therapy often unnecessary despite treatment challenges with associated fungal infections.

Folliculitis decalvans mainly affects middle-aged African American men and is treated with antibiotics.

This study described the diverse vibrissal follicle anatomy in fetuses of three cetacean species and observed species-specific differences, supporting further investigation into vibrissal form and function across cetaceans.

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

This study found that loss of the Pten gene in Lgr5+ hair follicle stem cells promoted squamous cell carcinoma formation through the Akt/β-catenin signaling pathway.

This review discusses a clinical approach to diagnosing alopecia through patient history and clinical findings, but it reports no new clinical results.

This paper introduces a new microscopy technique to measure biomagnetic fields of human hair follicles using Prussian Blue Stain mixed with iron particles, but it reports no new clinical results.

In this study, researchers observed significant morphological and histological differences in transplanted hair follicles compared to native donor follicles post-FUE hair transplantation for androgenetic alopecia, highlighting substantial variations in sebaceous gland and root sheath degeneration at the recipient site.

This case study describes a 33-year-old woman with chronic myelogenous leukemia who developed nonscarring alopecia after starting nilotinib therapy, linked to perifollicular inflammation.

This abstract provides no research results, focusing instead on navigation and subscription details for JAMA Dermatology content access.

Minoxidil works in liver and outer hair root sheath for hair growth.

This study observed that aging leads to significant structural and biological changes in the scalp's hair follicle environment in women, which may affect hair growth.

This study suggests that damaged anagen hair follicles have the capability to repair themselves and resume growth by mobilizing extra-bulge epithelial cells, particularly after injuries like chemotherapy and radiotherapy.

In this case study, a 24-year-old woman with frontal alopecia resembling frontal fibrosing alopecia was ultimately diagnosed with primary cutaneous follicle center lymphoma, highlighting the critical role of biopsy in identifying atypical alopecia presentations.

This abstract discusses the unclear role of dihydrotestosterone (DHT) in postembryonic life in marsupials and possibly humans, reporting no new findings.

In this study, smoking status and intensity were significantly associated with moderate or severe androgenetic alopecia among Asian men, after accounting for age and family history.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This study found that hirsutism and acanthosis nigricans are the most reliable skin markers for diagnosing polycystic ovary syndrome in women and suggest a need for further evaluation of possible metabolic issues.

This study observed that patients with CYLD mutations frequently experienced severe, painful tumors beyond the head and neck, impacting their quality of life, with hormonal factors possibly contributing to tumor development.

In this study, treatment with 1 mg of finasteride was associated with stable sexual function, suggesting that sexual side effects may be less common than indicated in clinical trials.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

This review develops expert-guided recommendations for hidradenitis suppurativa management, highlighting evidence for the effectiveness of antibacterial and anti-tumor necrosis factor therapies, but reports no new clinical trial results.

Finasteride can cause one-sided breast enlargement, which disappears after stopping the drug.

This study demonstrated that PEGDA hydrogel microwells successfully supported cell survival and proliferation while mimicking hair follicle architecture in vitro, suggesting a potential tool for hair follicle engineering.

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.
