research Integrative Proteo-Transcriptomic Characterization of Androgenetic Alopecia Identifying ME1-Mediated PPAR Signaling as a Potential Mediator
ME1 and PPAR signaling may influence hair loss in androgenetic alopecia.
research Evaluation of the Therapeutic Effects of AGA Drugs by Measuring Finasteride, Dutasteride, and Dihydrotestosterone in Hair
Finasteride and dutasteride effectively reduce DHT in hair, which may help evaluate their treatment success for hair loss.
research The Effects of Temperature, pH, and Moisture Exposure on Human Hair
High temperatures, acidic conditions, and too much coconut oil damage hair, while a pH of 5 to 7 keeps it healthy.
research Hair's Zinc Level in Androgenic Alopecia
Lower zinc levels in hair are linked to more severe male pattern baldness, but blood zinc levels don't show this link. Age also increases baldness severity.
research Nanomechanical Characterization of Human Hair Using Nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.
