research Effects of Hura crepitans and Its Active Ingredient, Daphne Factor F3, on Dihydrotestosterone-Induced Neurotrophin-4 Activation and Hair Retardation
Hura crepitans and its compound daphne factor F3 may help treat hair loss by blocking a specific hair growth inhibitor.
research The Circular RNA CircCOL1A1 Functions as a miR-149-5p Sponge to Regulate the Formation of Superior-Quality Brush Hair via the CMTM3/AR Axis
A specific RNA molecule, circCOL1A1, affects the growth and quality of goat hair by interacting with miR-149-5p and influencing cell growth pathways.
research Pattern of Hyperandrogenemia in Patients with Polycystic Ovary Syndrome at a Tertiary Care Hospital
Free testosterone is the most common hormone marker in PCOS, and age affects DHEAS levels.
research RP-HPLC-Based Stability-Indicating Analytical Method for Concurrent Determination of Finasteride and Tadalafil: Development and Validation
A reliable method was developed to measure Finasteride and Tadalafil together, showing they degrade under certain conditions.
research The role of dexamethasone in mediating the contradictory effects of Wnt antagonists SFRP2 and SFRP3 on human hair follicle growth
Dexamethasone affects hair growth by altering levels of proteins that either promote or inhibit hair follicle growth.
research Testosterone 5.ALPHA.-Reductase Inhibitory Active Constituents of Piper nigrum Leaf
Black pepper leaf extract contains compounds that can block testosterone effects and promote hair growth.
research 5α-Reductase activity in the human hair follicle concentrates in the dermal papilla
The enzyme that changes testosterone to a stronger form is mostly found in the part of the hair follicle called the dermal papilla.
research Hirsutism: A Clinico-investigative Study
Most cases of excessive hair growth in women are caused by polycystic ovarian syndrome and are linked to higher free testosterone levels.
research A computational modelling framework to quantify the effects of passaging cell lines
Cell characteristics change with passage numbers, affecting experiment results.
research Testosterone-like immunoreactivity in hair measured in minute sample amounts - a competitive radioimmunoassay with an adequate limit of detection
The new test can measure very small amounts of testosterone in hair, and grinding the hair up first gives more accurate results.
research Anti-androgenic curcumin analogues as steroid 5-alpha reductase inhibitors
Some curcumin-like compounds can effectively and safely block the enzyme linked to hair loss and other conditions related to male hormones.
