I killed my hair. One day, I decided to go blonde and instead of taking my time, I bleached it multiple times in a few days. Needless to say, my hair was bad. It was the texture of cotton candy when it was wet.
Anyway, I shopped around for an intensive treatment and found this. It worked wonders. Within a month, my hair felt seemingly normal again. Occasionally I'll use this if I feel like I've put too much heat on it to maintain the strength of my hair
