This review discusses diagnostic tools for scarring alopecias, emphasizing trichoscopy as a low-cost, non-invasive method for more accurate diagnosis, although it reports no new clinical results.

This review discusses recent advances in understanding the molecular mechanisms of androgenic alopecia and developments in its pharmacotherapy, with a focus on factors influencing hair follicle regeneration in genetically predisposed individuals.

In this study, researchers identified loss of function variants in the HR gene as likely causes of the distinct roaning hair coat seen in lykoi cats.

In this study, a 26-year-old woman with polycystic ovarian disease and advanced hair loss (Ludwig Grade III) showed reduced hair shedding and improved hair density after four sessions of platelet-rich plasma combined with microneedling, with no reported adverse effects.

In this study, a 26-year-old woman with polycystic ovarian disease and severe hair loss showed reduced hair shedding and improved hair density following four sessions of platelet-rich plasma combined with microneedling, with no adverse effects reported.

This study suggests that mNotch expression plays a significant role in hair follicle differentiation and cell fate selection within the follicle during development.

Testosterone and dihydrotestosterone affect hair growth, and new techniques like the folliculogram help study it, but fully understanding hair growth is still complex.

This study found that nonscarring alopecia in patients with systemic lupus erythematosus may indicate higher disease activity, as evidenced by specific histological and immunofluorescence changes.

In this study, researchers found that synchronization between expanding epithelial cells and background mesenchymal cells in the mouse hair cycle may be maintained by inhibitory regulation, with potential mediators of this regulation identified.

This case report documents a cancer survivor who experienced cyclic alopecia areata following chemotherapy, suggesting potential autoimmune changes related to the treatment.

Treatment with methotrexate and prednisolone led to complete hair regrowth and no relapse for 2 years.

This study found that shed hairs from the root significantly outnumber broken hairs during hair fall, particularly in Chinese male and female participants, with shedding predominantly occurring during washing.

This review explores the complex pathophysiology of androgenetic alopecia, highlighting genetic factors, androgen metabolism, and emerging therapies such as platelet-rich plasma and low-level laser therapy, but notes that no ultimate cure exists and treatments focus on slowing progression and promoting hair growth.

This study found that ultraviolet-induced fluorescence trichoscopy can help differentiate between scarring and non-scarring alopecia and between psoriasis and seborrheic dermatitis.

This abstract reviews eyebrow transplantation techniques, highlighting that follicular unit extraction prevents scarring at the donor site, unlike strip harvesting, and reports no new clinical results.

A woman's hair loss was correctly diagnosed as Lichen planopilaris after initial misdiagnosis, highlighting the usefulness of trichoscopy in diagnosing hair disorders.

This review discusses the pathogenesis, diagnosis, and treatment strategies for Central Centrifugal Cicatricial Alopecia, emphasizing a multifactorial approach and reporting no new clinical results.

This review discusses the diagnostic features of androgenetic alopecia through trichoscopy and reports no clinical results; it emphasizes hair shaft variability and yellow dots as key indicators.

This review discusses male androgenetic alopecia treatments, noting that topical minoxidil and oral finasteride are FDA-approved and require continuous use to maintain hair retention effects, but reports no new clinical results.

In this study, NAC was observed to counteract the negative effects of cyclophosphamide on hair follicles in mice, preserving both biochemical parameters and hair structure, suggesting its potential as a therapeutic option for chemotherapy-induced hair loss.

This chapter reviews trichoscopic features of primary cicatricial alopecias, particularly lichen planopilaris and frontal fibrosing alopecia, and reports no new results.

This review discusses the application of trichoscopy in diagnosing various hair and scalp diseases and reports no new clinical results; the authors emphasize its role as a non-invasive diagnostic tool.

This review summarizes the anatomical and physiological aspects of human hair and its clinical significance, but does not report new research findings.

In this study, the immunohistochemical and lectin binding profiles of basal cell carcinoma closely resembled those of the outer root sheath of vellus hair follicles, suggesting a potential histochemical relationship.

This study suggests that finasteride's effect on promoting hair growth in men with androgenetic alopecia may be due to its inhibition of 5aR2 localized in hair follicles.

Immunocompromised patients can develop skin and hair issues due to a virus.

This article discusses the trichoscopic diagnosis of temporal triangular alopecia, but reports no new clinical results.

Pubic hair transplantation can improve self-esteem in those with sparse pubic hair.

This case study speculates on a potential link between angiosarcoma and hair follicle miniaturization-induced alopecia in an elderly woman, suggesting possible directions for new treatment research.

This review discusses the role of hair microscopy in diagnosing alopecia, stating that while it excludes diagnoses related to hair breakage, it only confirms nonspecific short anagen in alopecia cases.
