First of all, you need to try to establish the exact cause of hair loss. Mostly it is hormonal. Accelerated hair loss men "owe" the hormone dihydrotestosterone, which has the ability to accumulate in the upper layer of the skin covering the head. Since the body of men this hormone is present in much greater numbers than women, and accumulates faster, respectively, and male baldness happens more often.
Your doctor may recommend such treatment: reception of the female hormone estrogen, which causes enhanced growth of hair. In most cases, it gives good results. However, hormone therapy can lead to side effects: you receive a higher "female" voice, changing the shape with fat deposition on the female" type. Therefore, such therapies should be used with caution.
The reason may lie in an unfavorable environment, as well as in the action of certain medications that weaken hair follicles. Therefore, you should minimize the intake of THESE medicines to a minimum, using them only in really necessary cases, and not "just in case", which, unfortunately, common.
Excitement, stress also contribute greatly to the hair loss. You should try to avoid them. Do not get involved unless absolutely necessary in a conflict situation, try to be calmer and friendlier.
The cause of accelerated hair loss can also lurk in such ordinary things as water. Because in different places it is different in quality: too hard, somewhere contains harmful ingredients. Known cases when shampooing filtered and boiled water gave very good results.
Sometimes very well help these "folk" remedies like massaging the scalp burdock, sea buckthorn oil, onion juice. It is also necessary to systematically eat the berries of sea buckthorn.
In any case it is better to consult a doctor. It is not excluded that the cause of the rapid hair loss is a serious disease!
