research Fadrozole and finasteride exposures modulate sex steroid- and thyroid hormone-related gene expression in Silurana (Xenopus) tropicalis early larval development
Fadrozole and finasteride change gene expression related to sex hormones and thyroid hormones in frog larvae development.
research Ultrasonic-assisted extraction and in-vitro antioxidant activity of polysaccharide from Hibiscus leaf
The study found an efficient method to extract antioxidants from Hibiscus leaves.
research Multi-layered environmental regulation on the homeostasis of stem cells: The saga of hair growth and alopecia
Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.
research Microneedling for the treatment of hair loss?
Microneedling can help stimulate hair growth, especially when used with other treatments, but it's not better than existing therapies.
research 46,XY DSD due to impaired androgen production
Impaired androgen production in 46,XY DSDs causes ambiguous genitalia and requires long-term care.
research Mutant laboratory mice with abnormalities in hair follicle morphogenesis, cycling, and/or structure: An update
The document concludes that mouse models are crucial for studying hair biology and that all mutant mice may have hair growth abnormalities that require detailed analysis to identify.
research Steroidal 5α-reductase and 17α-hydroxylase/17,20-lyase (CYP17) inhibitors useful in the treatment of prostatic diseases
Certain drugs that block specific enzymes can help treat prostate diseases.
research The essential oils of Chamaecyparis obtusa promote hair growth through the induction of vascular endothelial growth factor gene
Essential oils from Chamaecyparis obtusa may help hair grow by increasing a growth-related gene.
research Valproic acid promotes human hair growth in in vitro culture model
Valproic acid may help hair grow and could be a safe treatment for hair loss.
research Expression and roles of steroidogenic acute regulatory (StAR) protein in ‘non-classical’, extra-adrenal and extra-gonadal cells and tissues
The protein StAR is found in 17 different organs and can affect hair loss and brain functions, but its full role is not yet fully understood.
research Sex steroid synthesis in human skin in situ: The roles of aromatase and steroidogenic acute regulatory protein in the homeostasis of human skin
Human skin produces sex hormones like estrogen and testosterone, influenced by ARO and StAR, which may affect skin elasticity and hair growth.
research Hair growth-promoting effect of Aconiti Ciliare Tuber extract mediated by the activation of Wnt/β-catenin signaling
Aconiti Ciliare Tuber extract may help hair grow by activating a specific cell signaling pathway.
research Anti-androgenic effect of sesquiterpenes isolated from the rhizomes of Curcuma aeruginosa Roxb.
Germacrone from Curcuma aeruginosa may help treat conditions related to male hormones by blocking a specific enzyme.
research Hair Bundle Defects and Loss of Function in the Vestibular End Organs of Mice Lacking the Receptor-Like Inositol Lipid Phosphatase PTPRQ
Mutations in the PTPRQ gene cause significant balance issues in mice due to hair bundle defects in the inner ear.
research The enhancement of dermal papilla cell aggregation by extracellular matrix proteins through effects on cell–substratum adhesivity and cell motility
Skin cell clumping for hair growth is improved by a protein called fibronectin, which helps cells stick and move better.
research Formulation and in vitro evaluation of polymeric enteric nanoparticles as dermal carriers with pH-dependent targeting potential
Scientists created tiny particles that release medicine on the skin and in hair, working better at certain pH levels and being safe for skin cells.
research Application of mesenchymal stem cells derived from bone marrow and umbilical cord in human hair multiplication
Bone marrow and umbilical cord stem cells can help grow new hair.
research An ultrastuctural study of hair fiber damage and restoration following treatment with permanent hair dye
Permanent hair dye damages hair but it mostly recovers after 8 weeks; using certain hair care products can help repair it.
research Influence of massage and occlusion on the ex vivo skin penetration of rigid liposomes and invasomes
Massage increases how deep both rigid and flexible liposomes can go into skin, with flexible ones going deeper, and covering the skin (occlusion) helps rigid ones more.
research Age-related hair changes in men: Mechanisms and management of alopecia and graying
Men's hair loss is caused by hormones and genes, and can be treated with medication and surgery, while graying is due to aging and has no prevention except dyeing.
research BMI and levels of zinc, copper in hair, serum and urine of Turkish male patients with androgenetic alopecia
Lower hair zinc and copper levels found in Turkish males with hair loss; higher BMI linked to less hair zinc.
research Testosterone therapy in women: Myths and misconceptions
Testosterone therapy is beneficial for women's health and does not cause masculinization or liver damage, and it protects the heart and breasts.
research Epidemiology of hirsutism among women of reproductive age in the community: a simplified scoring system
A simplified scoring system can effectively diagnose hirsutism in Chinese women of reproductive age.
research Binary and ternary inclusion complexes of finasteride in HPβCD and polymers: Preparation and characterization
