This article discusses diagnostic challenges and management approaches for hair loss in women of color, emphasizing the importance of clinical examinations and education to prevent and manage traction alopecia.

This study describes the process of isolating and analyzing multipotent stem cells from mouse hair follicles for potential use in tissue engineering and regenerative medicine.

This study found that using a combination of video microscope for slivering and loupe magnification for graft-cutting in hair transplants achieved nearly double the graft productivity with similar transection rates compared to using only a digital video microscope.

This case report describes a 57-year-old woman with hirsutism, hair loss, and vocal changes, who was found to have elevated testosterone levels but normal dehydroepiandrosterone sulfate levels.

This article discusses methods for camouflaging surgical sites after hair transplant procedures and presents no new clinical findings.

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 review, the authors discuss recent advancements in underwater adhesion technologies, specifically highlighting mussel-inspired catechol-based adhesives, which offer strong underwater bonding through various interfacial interactions and the influence of dopamine-modified polymeric tissue adhesives.

Act quickly to prevent permanent hair loss from tight hairstyles.

Photographic imaging is crucial for documenting and managing hair loss, requiring careful preparation and standardization to be effective.

In this animal study, finasteride exposure led to impaired spermatogenesis in rats, while the novel compound DA-9401, derived from three medicinal herbs, demonstrated potential in improving sperm parameters and reducing testicular apoptosis when used alone or with finasteride.

In this study, oral tofacitinib treatment led to significant hair regrowth and changes in skin and blood biomarkers in a patient with alopecia areata.

This study found that males have significantly longer hair on their thighs compared to females, mainly due to a longer anagen phase and a greater rate of growth.

This study reported no significant difference in efficacy or sexual dysfunction risk between 5α-reductase inhibitors and placebo for androgenetic alopecia, suggesting that dutasteride 0.5 mg may be considered pending further research.

This study reports that a hair shedding threshold of 100 hairs or more may provide the best concordance with clinical diagnosis for distinguishing chronic telogen effluvium from androgenetic alopecia.

This review discusses the historical, legal, and clinical aspects of electrolysis and thermolysis, highlighting potential risks due to the lack of standardized training for electrologists in the United States, but reports no new clinical results.

In this study, minoxidil treatment was associated with an increase in nonvellus scalp hairs, but this effect was not sustained once the treatment was stopped.

This article reviews common skin eruptions in chemotherapy patients and discusses how recognizing these patterns can help avoid unnecessary changes to cancer treatment; it reports no new clinical results.

This study concluded that an endogenous circannual rhythm of prolactin secretion in mouflon influences their seasonal hair growth and moulting cycle, which varies under different photoperiodic and melatonin treatments.

This study observed that hair density and thickness were significantly reduced across multiple scalp sites in South Korean women with hair loss, highlighting potential patterns that could aid in differentiating hair disorders.

This study found that the TrichoScan method for evaluating hair loss showed excellent correlation with manual marking and provided more consistent, reproducible results with less variability and operator error.

This study found that hair diameter increases toward the scalp during pregnancy, a novel observation compared to the normal decrease seen in nonpregnant women.

In this study, nanocapsule-based preparations containing hinokitiol promoted hair growth in mice comparably to Minoxidil solution, as indicated by photographic and histological analysis.

In this study, 1% procyanidin B-2 tonic significantly increased the number of total and terminal hairs on the scalp of male participants compared to a placebo after 6 months of use.

This study found that miniaturization of hair is present in some women with androgenetic alopecia, but diagnosis may also be based on differences in hair shaft diameter between scalp regions.

This study found that Wnt3a increased beta-catenin signaling and upregulated specific genes in cultured human dermal papilla cells, enhancing their response to PGE2 and potentially aiding hair growth.

In this study, Scalp Immersion Proxigraphy (SIP) was shown to produce more accurate measurements of linear hair growth rate than crude phototrichogram techniques, suggesting SIP's suitability for clinical trials monitoring hair growth.
