My hair is very thin & curley skull is oily. it also fall when i comb after showering. which is the best male shampoo for this condition?

Thin hair: You can take biotin supplements to help with the hair and use Rogaine (minoxidil) for men over the counter.

Try this: Zinc pyrithione shampoo can be helpful to some people with oily scalps. Not evidence based - but another thing you can try to calm some anxiety of falling hair is to wash your hair every second day. Lastly, if you see a doctor and they think it's male pattern baldness there are meds like Minoxidil and Finasteride that you can try.
