If you are someone who has ever laid bleach on your hair you need this product. Period. I was tempted to end this post right here but let me back this up a little for you. I have been bleaching my hair for years. Luckily, I have really thick, strong hair. I really thought it was indestructible. Everyone would complain about how damaged their hair was but no matter how many times I highlighted it, my hair always stayed healthy. Until I decided to darken it and then in the same month lighten it again. First of all, don't EVER do that if you can avoid it. The first time I put a curling iron to my hair post doing this change back it broke. I was DEVASTATED!!! My hair was starting to break, my ends looked fried and I was just utterly devastated. I had just gotten a haircut and someone said "Once you get a haircut you'll be fine" cue the tears.
