Immunocytochemical Localization of Androgen Receptors in the Scalp of the Stumptail Macaque Monkey, a Model of Androgenetic Alopecia
April 1994
in “Journal of Investigative Dermatology”
TLDR Androgen receptors found in monkey scalps, similar to humans, affect hair growth.
This study used immunocytochemistry to locate androgen receptors (ARs) in the scalp of stumptail macaque monkeys, a model for androgenetic alopecia. The study found that ARs were present in the dermal sheath, outer root sheath, hair epithelium, and dermal papilla of the hair follicle, as well as in sebaceous and sweat glands. The distribution of ARs in the pilosebaceous unit of the stumptail macaque was found to be virtually identical to that in humans, suggesting that androgens regulate similar cellular targets in both species. The study provides additional evidence that scalp hair growth is at least partially mediated by androgens in this primate model.

research Hair growth effects of oral administration of finasteride, a steroid 5 alpha-reductase inhibitor, alone and in combination with topical minoxidil in the balding stumptail macaque.
Finasteride and minoxidil together promote hair growth better than either alone.
research The effects of topical diazoxide on hair follicular growth and physiology of the stumptailed macaque
Diazoxide applied to the skin can increase hair growth without harmful side effects.
research Increased Androgen Binding Capacity in Sebaceous Glands in Scalp of Male-pattern Baldness
Men with male-pattern baldness have more androgen receptors in their scalp's oil glands, which may contribute to hair loss.
research Action of topical minoxidil in the bald stump-tailed macaque
Minoxidil promotes hair growth but stops working when discontinued.
