The hair fall
that you are having is primarily due to PCOD. So the hormonal
medication that has been suggested by your gynaecologist needs to be continued till further advise. There is no harm in using minoxidil
for prolonged period, infact it can be used life long if required provided there are no significant side effects. However instead of using minoxidil 10% I would suggest you switch over to minoxidil 2% preferably in combination with amenexil (coverit Ax 2 or amexidil) as with minoxidil 10% chances of having redness
, stinging or itching over scalp
are more and there is no such benefit of minoxidil 10% over minoxidil 2% . Take care.
