I am 22 yrs old male. I have every thin hair on top of my head and low density, I am not bald I consulted a dermatologist, he prescribed me some vitamin pills which has biotin, etc etc in it. He also prescribed me Minscalp-F5% tropical solution, this solution has minoxidil 5% and finasteride 0.1 mg. He said me to shave my head, and apply this solution(1ml) daily on crown of my head before going to sleep. Now I did some digging online and it says if I stop using minoxidil after sometime, then it will cause severe hairfall. I am a bit nervous doc. Help me out.
