I'm 20 and i have been losing my hair for the past 7 years. i'm having balding areas.I have asked before if i can undergo a hair transplant and i have been told that i am not a good candidate due to my age. I ask if taking finasteride will help me to , at least, improve the situation a little bit. I am asking if this medicine can improve density and thicken hair, and improve the condition of my hair in general. is it safe as well?i've tried minoxidil and PRP sessions but nothing's worked for me.
