Hair and Scalp Variation Related to Gender

This review discusses the unique dermatologic needs of transgender individuals during transitioning and emphasizes the importance of accommodating care in medical settings; it reports no new clinical results.

In this case report, a transgender woman experienced scalp hair regrowth after approximately six months of oral estradiol and spironolactone treatment, achieving testosterone levels within the normal female range.

This study found that individuals with patterned hair loss, both male and female, showed a slower linear hair growth rate compared to controls with hair of equal thickness.

This study suggests that estrogen synthesis from estrone sulfate significantly influences hair growth regulation, with variations based on the hair growth phase, gender, and age.

This review discusses the therapeutic options for transgender individuals, including hormonal and surgical treatments, and reports no new clinical results; the authors highlight the need for more research on long-term effects.

This study suggests that prolactin has complex, gender- and location-dependent effects on human hair follicles, promoting hair growth in female frontotemporal scalp areas while inhibiting it in male occipital regions.

This review discusses gender-linked skin differences, such as hormone metabolism and sebum production, and reports no new findings; it suggests these insights might inform male-specific dermatological treatments or cosmetic products.

This review discusses recent advances in understanding gender differences in skin and their implications for dermatologic diseases, but it reports no new experimental results; ongoing research is necessary for translating these insights into clinical practice.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

This article reviews factors influencing hair aging and available treatments like minoxidil and finasteride for androgenetic alopecia but reports no new clinical results.

This article reviews the historical developments in understanding and treating male pattern hair loss, emphasizing the role of dihydrotestosterone and 5α-reductase inhibitors, but reports no new clinical findings.

This article reviews common hair-care practices among African American patients and discusses how these practices relate to hair and scalp disorders, without presenting new clinical research.

In this study, hair pain (trichodynia) was reported by a significant portion of patients with hair loss, but it did not correlate with the cause or activity of the condition.

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 successfully grew and maintained human hair follicles in vitro, noting that TGF-β1 negatively affects growth, while EGF replicates hair-removal effects seen in animals.

This paper reviews chemical analysis methods for trace elements in human hair and supports a no-wash policy due to challenges in distinguishing between endogenous and exogenous element sources.
