Hello Doctor, I saw experiencing hair fall problem since 4 years, i went and consulted a dermatologist and he suggested me use of minoxidil 2% and then suggested 5%. He didnt inform me initially that minoxidil should continue life long.Anyhow my hair fall stopped and regained my hair, but 1 year back my friend suggested that minoxidil may have several side effects over years so i stopped, as soon as i stopped minoxidil usage again my hair fall started double speed and now front liners n crowns are half way gone and became very thin, now i started using minoxidil 5% again, is there a possibility to get back my hair? Does stopping and restarting the minoxidil okay? Any longer side effects with minoxidil, could you please suggest me, can I continue using minoxidil 5% longer use?
