There was an interesting case report on a very unusual location for hair growth recently published in the Journal of Oral Surgery and Oral Medicine the other week. The case study was reported by Femiano et al. at the Second University of Naples, in Naples, Italy.
He reported a woman who was found to have hair growing inside her mouth due to a medical condition. Nasal-like hair. Scientists said it had to do with the the high level of testosterone in her system. They called it “oral hirsutism”, which I guess should be considered a new term in medical terminology.
Numerous conditions and serious diseases can result in high levels of circulating testosterone, although the most common cause of hirsutism is polycystic ovary syndrome (PCOS). In the future, maybe someday scientists specializing in hair follicle growth may utilize hormonal manipulations to grow hair on the scalps of men and women who qualify for hair loss treatment.
