research The quantification of reproductive hormones in the hair of captive adult brown bears and their application as indicators of sex and reproductive state
Measuring reproductive hormones in brown bear hair could help identify their sex and reproductive state, but better collection methods or lab techniques are needed.
research Safety concerns regarding 5α reductase inhibitors for the treatment of androgenetic alopecia
5α reductase inhibitors treat hair loss but may cause sexual side effects and risks.
research The effect of St. John’s wort on the pharmacokinetics, metabolism and biliary excretion of finasteride and its metabolites in healthy men
St. John's wort increases finasteride metabolism, reducing its effectiveness; use caution when combining them.
research Gas chromatography/mass spectrometry based hair steroid profiling may reveal pathogenesis in hair follicles of the scalp
Analyzing hair with this method can help understand and monitor scalp conditions and treatment effects.
research The clinical management of hirsutism
The document concludes that managing hirsutism involves identifying the cause, using a scoring system for severity, combining cosmetic and medical treatments, encouraging weight loss, and providing psychological support, while noting the need for more research on drug treatments.
research The anxiolytic effect of pregnancy in rats is reversed by finasteride

research Is age at puberty associated with semen quality and reproductive hormones in young adult life?
Men who start puberty later may have lower sperm quality and different hormone levels in adulthood.
research Cultured nail keratinocytes express hard keratins characteristic of nail and hair in vivo
Lab-grown nail cells show characteristics similar to natural nail and hair.
research External post mortem artefact: a key issue in hair result interpretation
Hair test results can be misleading due to contamination, so they shouldn't be used alone to determine drug use.
research Development of a new GC–MS/MS method for the determination of metformin in human hair
A new method was created to measure metformin in hair, showing potential for monitoring treatment and medical investigations.
research Within-person changes of cortisol, dehydroepiandrosterone, testosterone, estradiol, and progesterone in hair across pregnancy, with comparison to a non-pregnant reference group
Hormone levels in hair change during pregnancy, with progesterone increasing significantly compared to non-pregnant women.
research Technical Procedures for Preparation and Administration of Platelet-Rich Plasma and Related Products: A Scoping Review
The review found that the way Platelet-Rich Plasma is made varies a lot, which can change the results of medical treatments.
research Rational Design of a Topical Androgen Receptor Antagonist for the Suppression of Sebum Production with Properties Suitable for Follicular Delivery
