I started losing my hair when I was 17; 18 you could see the scalp in the crown area, 19 there was a HUGE hole, 20 there was a very visible receding hair line and with 21 almost nothing left. I am 24 years old now and slightly over four months using Grogenix Scalp Elixir sometimes I look in the mirror and I want to cry of happiness. It is not perfect yet but, in the front you can hardly see the scalp now, the entrances are diminishing, bangs are growing healthy and in the crown area I can see lots of new hairs growing, not enough yet to cover the whole scalp, however, if things continue progressing at the same rate they are, in about two more months my hair should be completely normal! I totally recommend this product!
