What is male pattern baldness? Male pattern baldness is a genetic problem, which affects millions of men worldwide. It is determined before birth whether a man will lose hair or not. You may not suffer from male pattern baldness by using shampoo or because of wearing a helmet, or hat, or due to frequent brushing of hair with comb. It is found that on an average, a man loses 100 to 150 strands of hair every day, but most of this hair re-grows because the follicle is healthy and intact. A typical adult head consists of about 150,000 hair follicles. Male pattern baldness is caused by the presence of a group of male sex hormones, which is collectively called androgens, in the body. The androgen level of bald men is not much higher than men who have full head crop of hair. effectiveness viagra benefits or viagra does viagra cause weakness viagra 100mg tablets jack nicholson quote viagra
