I got my hair colored a lot, everything from red to blond,the blond was the most damaging, I didn't know about moisture/protein balance and my ends suffered, I did co-wash every other day so it was moisturized. Now I don't get such lite coloring all over only as hi-lights, I also get Aveda hair coloring and my hair is not as dry.
I stopped ripping the comb through my hair, now I pretty much finger comb and use a large tooth comb during conditioning only, I retaining a lot more hair.
When I cut off the curly perm, I thought with moisturing it would be enough, it was only when I decided to grow my hair as long as possible that I found this site and started using such tools as braiding my hair at night, covering my hair with a silk scarf not cotton badana, and silk pillow cases, then my hair really started retaining, before this I had an area in the back middle part of my head that was three inches shorter than the surrounding area, now that area has filled in.
