Hi Anurag ,
Welcome to HCM.
Thanks for writing in.
It seems you have androgenetic alopecia
.It is a ongoing process and without treatment it can progress to alopecia or baldness
Mintop or minoxidil
is a treatment for hair loss.It must be accompanied by some other prescription medications.Early in the use Mintop may cause hair loss but it is effective in long run
Few nutritional treatments like biotin and calcium pantothenate
can be of help in preventing hair loss.
Consult a good dermatologist
for a complete and proper treatment. Using only Mintop and following your friends medication is not advisable.
Hope this helps.
Wishing you good health.
