I'm on the fence about this stuff still. It's EXTREMELY expensive, for what it is. I have been using it for four months now and should've seen a big improvement by now but I haven't. The only reason I'm still taking it is because I bought it as a BOGO deal and am praying that it will actually start to show some major results within the last two boxes that I have. I did notice a big change in the lessened amount of hair that falls out in the shower and on my brushes. And my baby hairs are able to grow longer without breaking finally. But for the hair that's already there and the length of it...the jury is still out. My advice... only get it if you have the money to buy it. Otherwise, if you want your hair to grow longer and healthier, take other methods into consideration. I personally love coconut oil at night (less than $7 at TJMAXX), biotin supplements ($5 at walmart), heat protectant sprays (Tresemme has great options all for cheap), and start using clips instead of hair ties.
