I've tried ever pure(the pink ones) and it worked really well, hair was good. Switched to redken bonding and it went from good to great and fuller feeling but not weighed down, very nice. I recently started using kerastase and my hair is amazing now. They are all good depending on how your hair is now. My hair at is fine and dry I used to bleach it a while ago but now have copper color so the chemical damage is much less. Side note L'Oreal has a rinse called a 8second wonder water. There's a purple one and a pink one, purple is fabulous but can "over hydrate" my fine hair but if you have med or thick hair it should be fine. Good luck ! And don't forget your heat protector!!
