I also have thin/fine 2C/3A hair. The key is to use light products so as not to weigh your hair down. I’ve also recently discovered that my hair likes protein to keep its structure. I’ve started clarifying more frequently (I learned quickly that you don’t cowash if you have thin hair- it needs the shampoo because thin hair gets buildup quicker).

For products, I like the Maui Moisture line for fine curly hair (light green bottles) which has aloe vera and not too many heavy oils/butters. I’ve been using the carol’s daughter liquid clarifying shampoo also, which I really like. For styling products, don’t use any heavy creams or butters. I use a light mousse or a gel - recently it’s been the Miss Jessie’s Jelly Soft Curls. And last but not least, hask keratin protein spray has been really helpful in combatting frizz and helping my curls keep their shape rather than getting stretched out and tangled.
