My hair is naturally dark brown, and I lighten/bleach all my hair. I used to use Joico K-Pack Reconstructor and Joico K-Pack Intense Hydrator, and NOW I'VE BEEN USING Tresemme's Split Remedy Shampoo, Split Remedy Conditioner, and Split Remedy Leave In Conditioner & Split Remedy Sealing Serum, and Tresemme's Split Remedy has significantly decreased my hair breakage. I read the ingredients on the back of Tresemme's Split Remedy products, and they put a lot of Hydrolyzed Keratin, Protein, Dimethicone, Panthenol, Biotin, and several other ingredients that significantly increase your hair's strength. The ingredients are almost identical to Joico's K-Pack Reconstructor collection, AND Tresemme's Split Remedy Collection is affordable. As you can probably already tell that I love Split Remedy by Tresemme because it has actually helped my hair!!!!!
