If your friend has lost substantial hairs within 4 weeks itself then it most probably is not male pattern baldness but rather due to some other medical reason. Accute illness or infections do cause short term hair loss but hairs lost in such conditions usually regrow when the health gets back to normal. Normal hair loss is considered to be below 100 hairs lost per day anything above that is not normal and would eventually lead to baldness in most cases unless treated properly.

he sure lost it fast! i don,t think it,s chemo or he would have lost all of it, not just on top. he probably just went bald, like me.i,ll tell you where to go, it,s a good site. go to ( bald r us )on the web. people of all ages tells their stories and you can ask tony, he,s the founder, any question you want.
