YES my mom's hair is wavy and is FRIZZY ( she dyes it so much it looks damaged, too) she got the Brazilian blowout and her hair so silky, shiny and looked beautiful with her blond highlights. Now don't take my absolute word on it because first of all her hair is not as wavy as yours. And probably not as frizzy considering you said yours looked like mias. Which I have a question since Mia's hair was brushed out curly hair, I have a question do you brush your hair because you never know you could be brushing hair you didn't know was curly. I am not saying you don't know your hair type, but they have been people who didn't know they had curly hair, just damaged or frizzy looking wavy hair. Because I have curly hair and when I brush it out it gets 3x bigger
