Normally used to treat ulcers and digestive problems, this medication also seems to have an anti-androgen effect, which prevents hair loss on the head AND hair growth on the face. This is a medication for women only! The high doses needed in preventing and curing hair loss can cause men to become feminized and have adverse sexual side effects.
It’s an over the counter medication (I actually used to take it for heartburn), but still check with your doctors before you take it for hair loss. Another thing I read about was that you could have possible reactions with other drugs you might be taking. So, if you checked with your doctor and everything, go ahead and buy cimetidine. It’s actually really cheap. Buy it online or pick it up at any pharmacy or grocery store with a good pharmacy aisle!
