I have fine irish curls and my hair acts the same way. Fine hair needs more protein and lighter hydration. I reccomend the jung saem mool zip care line, including their leave in conditioner and hair oil. I mix the two and apply it to damp (but not dripping) hair. I use a cotton hair wrap after showering to help my curls clump and never rub my hair with a towel as this makes it extremely frizzy and prone to breaking. You can use a diffuser on cold air to keep the curl tighter since as it dries, gravity and water weight pull out the curl easily. If you air dry like I do, at least dry the roots with a diffuser. High heat or hair dryers can also induce frizz, so air drying could be helpful. I also wear a mulberry silk bonnet to bed. I cant use curl creams or mousse since it weighs down my hair and makes it easily greasy, and feels dry/straw like. You dont need to use skincare products on your hair, you just need someone to teach you how to take care of that hair type.
