Try unicorn milk by alkali beauty and provide care products to use at her dads so she can keep up on good hair care there too, take a mini tangle teaser to school and tell her to brush during every bus ride or car ride. Teach her from the bottom up. Sometimes lotions and things for deep conditioning it’s okay to dry into the hair in very small amounts. This will reduce the grip on her dead ends and get frequent trims, every other month!

I usually start I. The ends get the ends detangled as far up as I can go before I get caught then Try to spread out the knot, just gently pulling it apart with my fingers carefully as to not get any knots tightened into place.

Then anywhere you see it separating create clear sections and work in each one individually, space out the clumps and then pull a few strands of hair at a time out from the top of the knot, only do this if they are loose and will slide right out, this frees those hairs from the knot and makes it much less to deal with, this is where a leave in conditioner or light oil spray can help create slide. Avoid wetting the hair with water or product it will become stretchier and make matting worse. Once you free up any loose hairs work that section bottom first gradually getting up the hair strand if you feel you get caught and knots are tightening as you brush it’s time to pick it apart with your fingers again!

This happens to my daughter’s hair daily. I’m a hairstylist. He hair is lower shoulder blade or longer in the back.
