This is the correct way to brush a doll's curly hair. Make sure it is damp when you brush it, or it will ruin the wig eventually. Also, be sure NOT to get any of the water in the doll's eyes when you are misting it - or they will rust.
It is very normal for the wig to lose a lot of hair when you are brushing the wig the first few days/weeks. It may seem excessive, but it's not. Trust me, evenually you won't lose much hair when brushing. Just be careful when you are brushing... Don't dig the bristles of the brush into the top of the head - you'll risk puncturing the wig cap with the bristles and ripping it. Also, start at the bottom, like you do with human hair, and work your way up.
Kanani is a very difficult first doll (just like Nicki was). If you child is younger, and you want to keep the doll looking nice - you might want to prepare yourself to do a lot of hair maintenance for her. Keeping Kanani's hair in a braid is a very good solution, as her hair is
excessively long and so difficult to manage. I have heard of some people bringing Kanani into their local stylist, and trimming a couple of inches off of the bottom of her hair to make it more manageable - this is a realistic solution - but I wouldn't attempt it yourself unless you are very confident in your skills, because what ever you do is permanent. I would also do it with out your other children (or dd) knowing that you did it - otherwise you might come home to Kanani with another hair cut, courtesy of a child.
Just go slow, dont stretch the strands of hair when you are brushing (that results in permanent frizzing that you can never get rid of) and mist, mist, mist. Wet hair is better than dry brushing.
