For reference: my hair is naturally gray, high porosity, fine with curl between a 2c/3a. I wasn't sure this brush would do anything for my flyaways/frizz but I find I use it every time I style my hair to smooth down my edges, top flyaways/frizz, and sides which are shaved close crop to my head. I haven't tried it on smooth back my head into a band or trying it before washing which now I'll definitely do. Never knew I needed this but so glad I found it! :)
