research Proteomic Tools for the Investigation of Human Hair Structural Proteins and Evidence of Weakness Sites on Hair Keratin Coil Segments
Hair proteins have weak spots in their α-helical segments.
research Metabolism of Minoxidil, a New Hypotensive Agent: Biotransformation Following Oral Administration to Rats, Dogs, and Monkeys
Minoxidil metabolizes similarly in monkeys and humans, but differently in dogs and rats.
research Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research In Vivo Investigation in Pigs of Intestinal Absorption, Hepatobiliary Disposition, and Metabolism of the 5α-Reductase Inhibitor Finasteride and the Effects of Coadministered Ketoconazole
Ketoconazole increases finasteride's effectiveness and lifespan in the body.
research Development of Fluridil, a Topical Suppressor of the Androgen Receptor in Androgenetic Alopecia

research Glucocorticoid Receptor Antagonism Improves Glucose Metabolism in a Mouse Model of Polycystic Ovary Syndrome
Blocking glucocorticoid receptors improves glucose metabolism in a PCOS mouse model.
research Data from Targeting Superficial or Nodular Basal Cell Carcinoma with Topically Formulated Small Molecule Inhibitor of Smoothened
The treatment was ineffective in humans.
research Two Hydroxyproline Galactosyltransferases, GALT5 and GALT2, Function in Arabinogalactan-Protein Glycosylation, Growth, and Development in Arabidopsis
GALT5 and GALT2 are important for plant growth and development because they help with protein glycosylation.
research In Vivo Uptake and Metabolism of Testosterone by the Skin and Other Tissues of the Rat
Rat skin takes up and processes testosterone differently than other organs, with testosterone being more important for the skin than its metabolite 5α-DHT.
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 Sulfation of Minoxidil by Liver Sulfotransferase
Liver enzyme helps minoxidil work better for blood vessel relaxation.
research The Effect of Experimental Hypothyroidism on the Skin of Adult Male Albino Rats and the Therapeutic Role of Topical Triiodothyronine
Hypothyroidism harms rat skin, but topical triiodothyronine may help improve it.
research The 5 Alpha-Reductase Isozyme Family: A Review of Basic Biology and Their Role in Human Diseases
The document concludes that the 5 alpha-reductase enzymes are important in steroid metabolism and related to various human diseases, with inhibitors used to treat conditions like male pattern baldness and prostate issues.
research Species Differences in Prostatic Steroid 5α-Reductases of Rat, Dog, and Human
Different animals have unique versions of the enzyme that changes testosterone into another hormone, which is important for creating effective treatments for prostate and hair loss conditions.
research Mechanism-Based Inhibition of Human Steroid 5α-Reductase by Finasteride: Enzyme-Catalyzed Formation of NADP-Dihydrofinasteride, a Potent Bisubstrate Analog Inhibitor
