This report describes two cases of stroke associated with finasteride use for male-pattern hair loss, suggesting a potential link to thrombosis due to increased estrone and estradiol levels.

In this prospective cohort study, male pattern baldness was identified as an independent predictor of prostate cancer, while the 2D:4D finger ratio was not associated with the cancer risk.

This review discusses female pattern hair loss, suggesting it involves both androgen-dependent and independent factors, but it reports no new clinical results.

This study suggests that chemotherapy-induced anagen effluvium represents patterned hair loss, with most patients retaining hairlines, but patterns do not vary significantly by age, symptoms, or chemotherapy type.

In this study, a home-use microneedle device combined with 5% minoxidil showed potential for enhancing hair growth in pattern hair loss over six months, although the observed improvements in hair count and patient assessments were not statistically significant compared to other treatments.

In this study of Indian patients with pattern hair loss, 40.8% showed low sulfotransferase enzyme activity in hair follicles, with a higher prevalence of low activity in men compared to women.

This study found that hairline measurements in white Spanish women differ from those previously reported for American women, which may be important for hair transplantation evaluations in alopecia cases.

This letter raises questions for the authors of a recent study on platelet-rich plasma for androgenetic alopecia, without presenting new clinical results.

This study found that while a modified BASP classification for pattern hair loss could classify previously unrecognized types, it was less accurate and harder to use than the existing BASP classification.

Results are not reported in this abstract, which focuses on promoting the offerings of a medical publisher in Delhi, India, including open access and print journals across various medical disciplines.

In this retrospective chart review, researchers found that keratinocyte carcinomas on the scalp and forehead of non-alopecic women occurred more frequently in the part line of the scalp, with basal cell carcinoma being more common than squamous cell carcinoma.

In this case report, a 21-year-old male was observed to have primary essential cutis verticis gyrata, a condition characterized by the excessive formation of scalp folds resembling cerebral gyri, without any additional comorbidities.

This study found that platelet-rich plasma significantly increased hair count, density, and the percentage of anagen hairs in patients with androgenetic alopecia, but these improvements did not correlate with platelet or growth factor levels.

In this study, researchers found that androgenetic alopecia is associated with increased gene expression related to inflammation, stress, and fibrosis, particularly affecting the hair follicle stem cells and showing similarities to diseases like psoriasis.

In this study, manually prepared platelet-rich plasma did not show significant improvement in hair count or anagen hair proportion for men with androgenetic alopecia.

This study developed a new semiquantitative grading scale for frontal and vertex androgenetic alopecia, which was found to be more sensitive and objective than existing classifications.

In this case study, a 69-year-old woman with pityriasis rubra pilaris developed a scarring alopecia with lichen-planopilaris-like features, which responded well to early treatment.

Detailed history and physical examination are crucial for diagnosing hair loss.

This article is a letter discussing variations in male sex hormone levels among different pattern subtypes of androgenetic alopecia and does not present new research results.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

This study found that transthyretin and megalin expression in human scalp hair follicles varies significantly with the hair growth cycle, peaking during anagen and diminishing in catagen and telogen phases.

This review discusses pharmacologic and non-pharmacologic treatments for androgenetic alopecia, noting that current medications like finasteride and minoxidil can slow hair loss but only partially restore hair growth, with early treatment offering better outcomes.

This study found that women with female pattern androgenic alopecia have significantly higher levels of certain androgens and androgen sulfates compared to normal premenopausal women, suggesting markers for diagnosis and treatment efficacy.

This study suggests that early initiation of treatment in fibrosing alopecia in a pattern distribution may lead to a more favorable outcome, as evident in some patients experiencing arrested disease progression and hair regrowth.

This study reports that plasma rich in growth factors appeared to improve hair follicle regeneration and patient satisfaction in individuals with androgenetic alopecia, though further trials are needed.

This review explores recent findings on the roles of melanocyte and melanocyte stem cells in the hair follicle, highlighting their importance for skin health and potential applications in regenerative medicine, but reports no new clinical results.

This study reported that using 5% minoxidil topical foam twice daily improved hair density and width in both the frontotemporal and vertex regions of men with moderate androgenetic alopecia.

This study found that combining needle-free intradermal minoxidil delivery with standard topical minoxidil therapy improved early hair growth parameters and satisfaction in women with early-stage female pattern hair loss compared to topical therapy alone, with no serious adverse events reported over the 10-week period.

This review discusses the current therapeutic options for female pattern hair loss and emphasizes the need for managing patient expectations of permanent regrowth, reporting no new clinical results.

This study offers a new perspective on androgenetic alopecia, suggesting that hair loss at the vertex and frontal scalp results from mechanical and thermodynamic stress, alongside androgen activity, and proposes that reducing mechanical tension and improving local microcirculation could complement traditional treatments.
