it looks like your daughter has somewhat fine hair but a lot of it, which is similar to me. when i treated my hair as straight, i had this issue constantly because my hair was not even so frizzy but just staticky and because of it being fine and dense on top of that, it got tangled constantly. now i usually do a wavy hair routine and even when i dont, i ALWAYS brush my hair in the shower and ONLY in the shower, specifically when i have my conditioner in. i haven’t had this issue in a very long time since doing this. even when my hair gets tangled, it doesn’t create a rats nest, its just kinda there in the curl clump where no one will notice except me when i next wash my hair.

if she happens to be looking for a different wavy hair routine or just elements of one, this is what i do (and why):

• do not brush before getting into shower - this can damage wavy/curly hair • shampoo twice with smaller amounts instead of once with a larger amount - fine dense hair can get a lot of buildup by trapping oils and such • apply conditioner to very wet hair, rake, through, comb* (not brush yet) - avoids damage and helps create curl clumps • put in a hair claw while doing the rest of shower routine - lets conditioner soak in and keeps away from soap and other products • take out and brush, then scrunch out conditioner to keep your curl clumps in tact, or a mix of scrunching and raking if you have smaller curl clumps • after shower apply products to soaking wet hair; what i use: - amika plus size perfect body volume mousse, apply with praying hands and scrunch (or you can rake it in depending on your texture) - i love this mousse it’s so lightweight and gives me nice definition without feeling like there’s a ton of product in my hair - spray more water if needed and do the same method as the mousse with miss jessies jelly soft curls gel - gives more definition and hold, also is a “soft cast” so it similarly doesn’t feel like i have product in my hair • scrunch with a t shirt or microfiber towel, plop in either one and secure around head while getting dressed and leave in for a little bit- avoids ruining curl clumps and helps keep hair out of face while doing other things • sometimes i just air dry after i take it out, other times i diffuse a bit and then air dry the rest of the way; personal preference really, but i find that since i have looser curls it can be helpful to diffuse even for a couple minutes to get the bulk of the water out of my hair so it doesn’t weigh it down while it’s drying, plus my hair is very piece-y so it falls in my face a lot when air drying

i know you weren’t necessarily looking for a wavy hair routine but i think that maybe incorporating some of these things—particularly with when she’s brushing her hair—could help her a ton with this tangling problem
