As far as brands that are available at drugstores I know shea moisture and the yes to lines are cruelty free. I like both and my hair is roughly 2c when styled and they are between 8-10 dollars a bottle usually. The shea moisture shampoos are amazing in my opinion, they're really gentle and don't strip your hair. And, I have heard some people compare the yes to carrots pampering condish to the much more expensive deva one condish. I personally don't really see that similarity, but I do really like it. (I also wasn't fond of the deva line so I'm a little biased there.)

If you want to spend a little more the kinky curly line is also cruelty free but they are like $12-15 a bottle (estimate, I haven't bought those in a while) many people here, including myself, like their curling custard and one bottle lasts forever.

I can't think of any others at the moment
