Definitely try using a product with humectants in it. I personally love Carol's Daughter hair balm. It locks in moisture and helps attract moisture for fuller and bouncier curls!
Love my auburn 3b/3c curls!! Favorite products are Treseme Naturals conditioner and DevaCare ArcAngel(<---miracle for definition!) I really just want to GROW MY HAIR OUT!! It's not really working...
