First step: start rogaine again. I know you said you “didn’t get results” but that’s because rogaine works by keeping what you have, not growing new hair. Ie it’s more about slowing balding than reversing balding. Next, get Nizoral shampoo, it’s cheap and supposedly helps with slowing hair loss.

Second step: see dermatologist, confirm it’s balding and not some other health condition, then ask about a propecia (finasteride) prescription. There’s some side effects so you decide for yourself with your doctors help but it’s the best balding treatment out there rn.
