research The stimulation of hair growth in the flank organs of female hamsters by subcutaneous testosterone propionate and its inhibition by topical cyproterone acetate: dose-response studies
Testosterone increases hamster hair growth; cyproterone acetate reduces it.
research Dermal papilla cell number specifies hair size, shape and cycling and its reduction causes follicular decline
More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.
research Different patterns of 5α-reductase expression, cellular distribution, and testosterone metabolism in human follicular dermal papilla cells
Androgen effects on hair follicles vary by skin area.
research Abstract 22: Tafluprost, a Prostaglandin F2α Analog, Has Therapeutic Potential for Androgenic Alopecia through Modulation of Hair Cycle
