2 X Alpecin Caffeine Shampoo

The product states for men,but I have short thin hair and figured I would try it. The very first time I used it I knew it was great. I have to use gel and a volume product to style. I used nothing after shampooing with Alpecin I blow dried my hair and instantly I saw major volume ,my hair did not lay flat on my head. also I left it on longer than suggested. The next day it still had more volume than normal. I have not used it long enough to see if it helps with hair growth. I wish it came in a bigger bottle and not so pricey for the size.
