This review found that dutasteride and finasteride are rarely associated with sexual side effects when used off-label for female hair loss, and suggests further study of their efficacy and side effect profile.

Hair loss can happen after severe H1N1 flu but usually grows back in 4 months.

This study found that G protein-coupled estrogen receptor enhances melanin synthesis in melanoma cells through cAMP-PKA-MITF-TYR signaling, suggesting its potential as a drug target for chloasma treatment.

This review examines the neuroendocrine mechanisms underlying seasonal changes in mammals and highlights areas needing further research, reporting no new experimental results.

This study reports that low levels of HDL cholesterol and IGF-1 were associated with a higher risk of hair loss in middle-aged women, but causal relationships remain uncertain.

This article reviews how SALT scores are used in clinical trials for alopecia areata and provides patient images to help clinicians understand and apply these scores in practice; it reports no new clinical results.

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.

Women with thinning hair have thinner hair strands than women without hair loss.

This review discusses the influence of androgens on hair and sebaceous growth, emphasizing that response may depend more on peripheral sensitivity than on hormone levels; it reports no new empirical results.

Hidradenitis suppurativa improves with antiandrogen therapy.

Hair loss in women often doesn't follow a pattern, isn't linked to age, may be genetic, and can be related to thyroid issues or other health factors.

This study found that thyroxine increased hair growth rate in rats, but estradiol decreased it, with both hormones affecting follicular cycles independently without altering ultimate hair length.

In this study, epilation in female rats generally accelerated hair eruption, especially in successive cycles, with variations influenced by hormonal treatments and timing within the hair growth cycle.

This article discusses whether testosterone's metabolism to 5α-dihydrotestosterone is necessary for androgenic effects in the skin but reports no new experimental results.

This study suggests that in rat skin, testosterone itself may play a more significant role in androgen action than 5α-dihydrotestosterone, unlike in the prostate where 5α-DHT is more dominant.

In this study, hirsute women treated with cyproterone acetate and ethinyloestradiol experienced significant reductions in sebum secretion and hair growth after several months.

This article reviews the use of anti-androgens, particularly cyproterone acetate, for managing hirsutism, but does not provide new clinical results.

This review highlights recent advances in understanding how the extracellular matrix regulates epidermal stem cell fate, emphasizing the importance of the hair follicle stem cell niche, but reports no new empirical findings.

A man got severe skin irritation after using marking nut sap for hair loss.

This review discusses the regenerative potential of hair follicle stem cell populations and current approaches to reconstructing folliculogenesis for alopecia therapy, but reports no new clinical results.

Skin cells can help create early hair-like structures in lab cultures.

A new cosmetic cream reduced facial redness and skin temperature after 4 weeks of use.

This review discusses the neurobiology of sexual function and reports no new results; the authors cover multiple endocrine and neurotransmitter influences on sexual desire, arousal, and orgasm stages.

In this study, the researchers reported that Notch/CSL signaling is crucial for hair follicle differentiation, with Wnt5a signaling and FoxN1 acting as mediators in mice.

This review discusses the classifications, diagnostic methods, and treatment strategies for female pattern hair loss, but reports no clinical results.

This study found that Zizyphus jujuba essential oil enhanced hair growth in mice, with the 1% and 10% concentrations showing increased hair length compared to control.

This study observed that in vitro treatment of male frontotemporal scalp hair follicles with 17-β-estradiol stimulated hair shaft generation and hair matrix keratinocyte proliferation, suggesting potential anagen-prolonging effects.

This study found that men with androgenetic alopecia had significantly lower levels of sex hormone binding globulin and higher salivary testosterone compared to controls, while plasma testosterone levels did not differ.
