Hi. My son is bi-racial, 8.5 months old and I think his new hair growth is around 3b/c. DH usually bathes him and just was washing his hair with live clean baby products- his hair was looking texture wise like mine-2b. Then we went swimming, I put sunscreen on his head (lost hat) and after he got wet suddenly these beautiful tighter curls appeared. DH and I decided we want to grow and encourage his curls but not sure how. I have tried grapeseed oil and bed head moisture maniac as a leave ins but no repeat curls. Any product recommendations suitable to his age and hair type?
