It's not only about genetics, you need to find a good doctor, a trichologist who will prescribe treatment based on blood tests, and you need to completely revise your diet, all health problems come from the lifestyle.
You don't need to look at your father, you need to look at your maternal grandfather or great-grandfather. At the moment, there are only two ways to stop wasting, these are hair transplant and a 5-alpha reductase inhibitor (finasteride). If everything is more or less clear with the transplant, then the last drug has a lot of side effects, because it inhibits the conversion from low-active testosterone to active dehydrotestterone, which is the most powerful natural androgyne and anabolic; without it, femenization of the body occurs. Therefore, androgenic alopecia without severe side effects cannot be treated and there is no way to stop it. Neither shampoo, mask, etc. will help. Although the traumatization of the baldness area is now being investigated, it seems with good results. For 2018, the most optimal and harmless option is to "hammer the cock" and go bald further. Or Kobzon method.
In view of the fact that this is usually associated with a lack of vitamins and minerals, there is such a procedure as mesotherapy. Its essence is that vitamin cocktails are "injected" directly (because for their intended purpose "cocktails" are much better absorbed than any vitamin complexes in tablets). As an option, various masks are made with nicotinic acid (in ampoules) - they are not expensive, but the effect is "worth it". I myself have had periods (especially in winter) when the hair literally "fell out", and rubbing in nicotinic acid seemed to help. But, in any case, all this is usually treated; it is enough just to find a good specialist trichologist, if the problem is serious enough (and does not lie in the banal avitominosis). P.S. Photo by Pavel Durov "BEFORE" he became famous, I think it will be appropriate here.
You can try shampoos if this is due to the quality of the hair. Perhaps this is due to bad blood, you can go get tested. If it's not about blood, see a dermatologist
