Male pattern baldness signs develop at different ages. Some men begin to lose their hair as early as their late twenties. Others do not show hair loss until they are in their forties. Regardless of how soon or late they occur, these signs do not have to mean one is condemned to being bald the rest of his life.
The first sign is a receding hair line that pulls back from the forehead above the temples, often leaving a point in the center so that the hairline resembles an M. Hair also begins to fall out at the crown. Over time, the hair recedes back until it meets the thinning at the crown so that one only has hair on the sides and back of the head.
When one first notices excessive hair loss, he has options of how to deal with it. If a man is not concerned about his appearance too much, he can choose to do nothing and let his baldness progress naturally. Most men seek out methods of stopping or reversing the process in order to keep themselves looking younger and more virile.
Minoxidil is one of the first drugs that has been found to help stop hair loss. It is sold in a topical formula that is applied directly to the scalp. Finasteride is another medication that is available by prescription and is taken in pill form. Both of these work to block the formation of the male hormone, DHT (dihydrotestosterone). This hormone has been found to bind itself to hair follicles and cause hair loss.
Male pattern baldness signs are relatively uniform across all races. Patchy hair loss or other atypical forms of thinning hair are most likely caused by other factors that can be changed to halt and/or reverse the hair loss in most cases.
