Someone please tell me how I can keep my sons hair from tangling so bad😂😭

Right now we shampoo and condition 1-2 times a week.

The back of his head gets sooo tangled from him rolling around. So much so that the back curls differently than the rest of his hair (instead of tight curls it’s like straight with a random curve lol)

I didn’t know if there are any products that could help with it tangling, or if we just deal with it until he grows out of all the rolling around

Also

He has really nice curls but then like an inch of straight frizz on top so if there’s any tips for that too I’d appreciate it😂
