research Partial Biotinidase Deficiency: Clinical and Biochemical Features
Children with partial biotinidase deficiency are healthy at birth but may develop symptoms that improve with biotin therapy.
research Induction of Dark Keratinocytes by 12-O-Tetradecanoyl-Phorbol-13-Acetate and Mezerein as an Indicator of Tumor-Promoting Efficiency

research Azasteroids as Inhibitors of Testosterone 5α-Reductase in Mammalian Skin
Certain 4-azasteroids are effective at blocking the enzyme that processes testosterone in human skin and could help treat acne, excessive hair growth, and male pattern baldness.
research Superiority of Dutasteride Over Finasteride in Hair Regrowth and Reversal of Miniaturization in Men With Androgenetic Alopecia: A Randomized Controlled Open-Label, Evaluator-Blinded Study
Dutasteride is more effective than finasteride at increasing hair count and reversing hair thinning in men with hair loss, but both have similar side effects.
research The Effect of Polyphloretin Phosphate, Polyoestradiol Phosphate, a Diphosphonate, and a Polyphosphate on Calcification Induced by Dihydrotachysterol in Skin, Aorta, and Kidney of Rats
The diphosphonate was the most effective at preventing calcification in rats.
research Male Pattern Baldness and Prostate Cancer Risk in a Population-Based Case-Control Study
Men who start losing hair at age 30 may have a lower risk of prostate cancer.
research Diffusion Properties of Model Compounds in Artificial Sebum
Different compounds move through artificial sebum at different rates, which can help choose the best ones for targeting hair follicles.
research The Fibroblast as a Model for Androgen Resistant States
Fibroblasts help understand androgen resistance at the cellular level.
research Necrosis of the Donor Site After Hair Restoration With Follicular Unit Extraction: A Case Report

research Loose Anagen Hair
Loose anagen hair can appear at any age and may improve over time.
research Evaluation of New Pregnane Derivatives as 5α-Reductase Inhibitors
New pregnane derivatives are effective at inhibiting an enzyme linked to hair loss and reducing oil gland activity.
research New Progesterone Esters as 5α-Reductase Inhibitors
Some new progesterone derivatives are better at blocking testosterone conversion than a common drug.
research Divergent Proliferation Patterns of Distinct Human Hair Follicle Epithelial Progenitor Niches In Situ and Their Differential Responsiveness to Prostaglandin D2
Different human hair follicle stem cells grow at different rates and respond differently to a baldness-related compound.
research Study of Seed Hair Growth in Populus Tomentosa, an Important Character of Female Floral Bud Development
Poplar seed hairs grow from the placenta at the ovary base, with endoreduplication playing a key role in their development, and share similar cellulose synthesis processes with cotton fibers.
