Now we know what male pattern baldness is and the next question that comes in our mind is about it causes and reasons. Why male pattern baldness occurs? The baldness is a process, not a one-day event. The gradual changes like thinning of hair, shrinkage of hair follicles, etc occurs first and then finally the hair fall. In the case of male pattern baldness, the reason of this changes in hair follicle structure is hormones. The male hormone, testosterone because of some reasons convert into dihydrotestosterone in the scalp’s cell. When the hair follicles get sensitive to dihydrotestosterone, the changes in follicles structures begin. But there are no explanations for the questions like why all the scalp hair don’t get affected with it and why other bodily hairs don’t fall? The MPB normally occurs because of hereditary reasons. If a father is affected with it, there is a great possibility that a son will also get affected with it. In this, many different genes are involved.
