Hi, Thanks for posting your query
, which is primarily a hypertensive agent.
When used topically it dilates the blood vesels hence increases the blood supply to the scalp.
secondly it converts fine hair to coarse hair , so it is used in hair fall
in your case the hair fall can be either Telogen effluvium
which is self limiting or andrgenic alopecia
, which has a heriditary predisposition.
You should get yourself examined by your trichologist to know the type of alopecia and the stage
and other medications as only minoxidil may not help
Hope this answers your query
