I am on finasteride + minoxidil + HRT for something around 45 days and until now it seems that my hair is slowly starting to grow on bald areas (mainly corners). When I look at the mirror I can see small tiny almost invisible hairs and it is enough to make my day =D
As it was stated, if your hair loss happened recently (your bald area can't be lustrous), you have good chances of recovering your hair. It will not be as strong and full as it was one day and requires patience, but it will improve your look!
And if the medicines are not being effective your if you are without patience, there are always good ways to get your hair back if you the have money. A hair transplant is a good choice.
Or, if you are almost begging money at the streets like me (lol), a wig and a lot of patience will do :/
