Super fine hair care

Little on finally has hair 😂 but it is the finest hair you’ve ever seen and a light breeze will leave it looking like a rats nest! I’ve been using baby shampoo and de-tangling with argan oil while the hair is still damp. It works ok and his hair is very soft and shiny, but I’m looking for any tips on how to tame the frizz and prevent tangles. Both his parents have fine, straight hair, so this is going to be a struggle for a while!
