S.M.
I am a licensed hairstylist with a four year old with very long curly and tangley hair. The trick is to only brush her hair when it is dry. What I do with Emma is: during her bath I use detangler and I use a big wide tooth comb and comb the conditioner in, starting at the ends and working my way up. I usually put Paul Mitchell Super Skinny Serum (however any silicone serum will do) in her hair while it's still wet and put it in braids for the night. In the morning I use a paddle brush, starting at the ends and working up the hair and it's very easy to brush. The Super Skinny Serum costs a bit much but it lasts for a really long time because you only use a dime size. You can also use a very small amount on dry hair to help de-tangle it. If you have any more questions I'm happy to help.
