It is true that spear mint helps in reducing facial hair growth or hirsutism. Spear mint helps in binding to the free testosterone and helps in prevention of conversion of normal hair follicles into coarse hair follicles. If you are regularly waxing or plucking coarse hair over chin including spear mint tea or fresh spearmint in your routine can help in reducing the growth of coarse hair. i.e. reduce the rate at which the coarse hair is growing. However if you have too many or the coarse hair growth is really large or in large amounts on your face spear mint alone may not help and you may have to look to other options like laser hair removal. It is not a bad thing at all. I completely recommend it. Do include spear mint fresh or spear mint tea in your routine. 3 to 4 cups is recommended. However there is a caution which goes along if you are sexually active because spear mint reduces testosterone. Sex drive may be reduced if you overdo spear mint. So that is the only contraindication that goes with spear mint. If you are fine with it do use spearmint in your routine and you will experience some change in the growth of coarse hair over a period of 3 to 4 months.
