Firstly, i do appreciate you all .My concern is that i was adivced to uses after a HT FUE in Turkey to use a hair vitamin named Xpecia which is a Turkish's Product for 6 months which i'm afraid of the side effect if there is and is it considered a finasteride !. Last thing if you allow me , does it work enough to prevent the original hair by using only multi vitamins or special hair vitamin like hair,skin and nails with Rogain or i must go with finasteride ones for DHT . Appreciated
