A woman whose real name I do not know has posted a fabulous list of curl-friendly products. None of them contain silicones or sulfates, and she also excludes protein-based ingredients. (Her thinking is that many curlies are protein-sensitive: protein is great in deep treatments but for daily use, it dries out some people's hair and leaves it coarse.) Her whole site is great so roam around once you get there!
After discovering that curls can be nurtured into fabulousness instead of frizz, I began my quest to cultivate healthy, moisturized hair. I don't use anything with sulfates or silicones, and like my hair at last! This blog is one way I am indulging my obsession.
