You have a choice. Alopecia areata is often impossible to treat effectively. You are almost a grown man and you have the option of embracing what has happened to you.

Relax. Alopecia totalis? Completley bald? No hair for 10 years? If this is the case there is no easy treatment. Be careful to avoid treatments worse than the condition you have. Also be prepared to ignore the fast-talking conmen selling all sorts of snake oil. At least you do not need to waste time shaving. Notice how many glamorous, sexy guys have the bald look?!

Simvistatin, laser. Two treatments that work for resistant cases is the excimer laser used for psoriaisis and vitiligo as well as oral simvistatin a cholesterol lowering drug which works to decrease inflammation and allow regrowth of hair in alopecia areata. The combination can work in resistant cases.
