my hair resembled wet knotted Barbie hair after i went from black to platinum in under a week using box dye and bleach, my hairs naturally curly and was FRIED after. if i left my hair to long without brushing it, it would rat up on one spot on my head and it would take hours to get out without my hair breaking like crazy, ive been using Garnier Fructis' Long & Strong shampoo, conditioner & leave in conditioner for almost 2 years and it works AMAZINGLY!!! NO split ends, NO breaking. it only took a week and a half of using it for my hair to adjust and i saw crazy good results.
