does the hair fall problem due to genetic can be cured? i started losing my hair since last 2 years. i shampoo my hair daily because if not, my scalp becomes oily and itchy. any suggestion shampoo for me?

hi guys. im 24 and i hv MPB due to family history. i hv oily scalp and thin hair if i dont wash and shampoo it daily. i used many products including himalaya and minoxidil. minoxidil works for me but if stop using it, my hair falls alot, and the product is quite expensive. then, i stop using it and change to natural way to regrow healthy hair. now im using biotin b-complex shampoo and taking b-complex and multi vit. so far, the result is satisfied after 1 months using them, i can see my hair is thicker and healthy,but my hair still doesnt stop falling. from my observation, i can see hv weak hair root since my hair falls along with the root(white thing at the bottom of it). is there any product to strenghten hair root? it is okay to use the recommended product with my current product? no side effect?
thanks.
