Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.

In this study, high-resolution ultrasound imaging revealed that DHT administration in male C57BL/6 mice leads to increased epidermal and dermal thicknesses and decreased skin elasticity, simulating structural changes associated with Androgenetic Alopecia.

This study found that dermal white adipose tissue surrounding human hair follicles enhances proliferation, pigmentation, and hair shaft elongation in an ex vivo setting.

This study evaluated the potential toxicity of oral dihydroartemisinin in SD rats, finding that female rats experienced greater toxic effects than males, particularly at higher doses, but these effects were reversible after a 4-week recovery period.

This source describes alopecia as a hair loss condition often driven by genetic and androgenic factors, with lifestyle elements like chemical treatments exacerbating the issue; Ayurvedic texts caution against scalp toxins and suggest traditional formulations for support.

This study found that 1,25-dihydroxyvitamin D3 promotes hair growth and regeneration in mice by prolonging the anagen phase and counteracting DHT's inhibitory effects, suggesting its potential therapeutic role for androgenetic alopecia.

In this study, topical dehydroepiandrosterone (DHEA) doubled sebum production in women without systemic side effects, suggesting it may be a safe treatment for reduced sebum output related to menopause.

This study found that the humanin analogue HNG significantly promoted hair growth in vitro and in vivo by prolonging the anagen phase and inhibiting hair follicle cell apoptosis in mice.

This abstract discusses the unclear role of dihydrotestosterone (DHT) in postembryonic life in marsupials and possibly humans, reporting no new findings.

This study reports that the β-catenin inhibitor tegatrabetan reduced hair growth and hair follicle numbers in mice, suggesting its potential as a model for developing new hair growth materials.

In this study, treatment with recombinant DKK2 was shown to significantly stimulate hair progenitor cell growth and enhance hair shaft elongation in ex vivo human hair follicle cultures by activating the Wnt/ẞ-catenin signaling pathway, suggesting a potential role for DKK2 in promoting hair growth.

In this study, high concentrations of dihydrotestosterone and testosterone reduced the growth of human hair follicle cells in vitro, while high estradiol levels increased their growth.

This study found that in wild-type Arabidopsis plants, root hair growth is suppressed with increased nutrient availability, with RHD6 subfamily genes down-regulated and GTL1 and DF1 genes influencing root hair morphology under these conditions.

This study found that administering tolerogenic dendritic cell-conditioned medium to dihydrotestosterone-treated mice promoted hair regrowth by modulating the follicular microenvironment, reducing pro-inflammatory cytokines, and activating key signaling pathways, highlighting its potential as a treatment for androgenetic alopecia.

This review discusses diosgenin's potential benefits for several chronic diseases and emphasizes extraction and quantification techniques, but reports no clinical findings.

Human hair follicles can process steroid hormones like DHEA.

Dermal IgA deposition without symptoms is rare in Dermatitis herpetiformis risk groups.

This study suggests that impaired VDR signaling in mice leads to dysregulated Ddit4 expression, impacting hair cycle progression and wound healing.

This article discusses the potential role of oral DHEA, available as a 'dietary supplement' in the US, in COVID-19 morbidity and mortality, calling for clinical trials to assess its safety.

This study suggests that women with idiopathic hirsutism have increased 5α-reductase activity, indicated by elevated levels of 3α-diol glucuronide; further research is needed to assess its clinical biomarker potential.

This study describes the enzymatic processes through which DHEA is converted to active sex steroids in human skin, highlighting an androgenic effect on sebaceous glands and estrogenic effects in the vagina.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

Dihydrotestosterone (DHT) worsens heart enlargement, and blocking it may help prevent heart issues.

The body's change of testosterone into DHT is not necessary for testosterone's muscle and sexual effects.

This study found that human placenta hydrolysate effectively inhibited atopic dermatitis development in stimulated human cells and a mouse model, suggesting its potential as a therapeutic agent for related skin diseases.

This study found that dexamethasone treatment inhibited the inflammatory response and the induction of ornithine decarboxylase activity in mouse skin after TPA application, although the effect on ODC was weaker during the hyperplastic stage.

This case report identifies a novel CDH3 gene mutation associated with hypotrichosis with juvenile macular dystrophy in a 13-year-old Turkish girl, highlighting implications for future genetic analysis and counseling.

The medicine Diane is effective in treating hair loss, severe acne, and excessive hair growth.

This article discusses the complexities of diagnosing hyperandrogenism in women and reviews potential treatments, such as antiandrogens and finasteride, but reports no new clinical findings.

In this study, daily administration of 100mg DHEA for 16 weeks in women with adequate ovarian reserve did not modify metabolic or reproductive variables, apart from increased antral follicular count and anti-Müllerian hormone levels.
