I'm looking for a good deep conditioner for my hair that I can use twice a week or so. Right now I'm using Redken Color Extend shampoo and conditioner for everyday use. Once a week I use Bumble & Bumble Sunday Clarifying shampoo to get rid of styling gunk. I do color my hair, and lately it's been very brittle at the ends and breaking off in certain places My hair is thick and wavy, and I blowdry it straight most days, but usually take Sunday off from doing anything to it. Any suggestions would be great, I'm in dire need of hair help!
