There are several products on the market called afro hair detangler so you will have your hands full trying to choose one to spend your money on. There are some favorites out on the market though. I do list one in this post.
Most women use a bone comb and go through the detangling process when their hair is wet to avoid pulling out follicles. Once the hair is sectioned out you can use something like Jane Carter’s revitalizing leave-in-conditioner to spray the hair as you comb out your kinks. The reviews for this product are really good and I have used it too and have zero complaints.
