I also had a brazillian treatment on my hair. So you know I had it about a year and a half ago. I have african american hair and at the time it was chemically relaxed. So, my hair was straight but it still would completely frizz out as soon as it got humid and it took about an hour to completely blow dry and flat iron it.( Even relaxed I know ugh) Anyway, I went ahead and had the keratin treatment over my relaxer. Pros: The humidity could not TOUCH my hair. I went outside and watched all my friend's hair grow all big but mine stayed sleek. Shine, My hair shined like nobody's business. Drying time: I cut down my blowdrying time to no more than 10 min and flat ironed only the top layer of my hair.
CON: it's so expensive. It cost me $250 BURNED: the stylist burned my ends so bad that They were fried. My hair is brown but the fried ends were like orange almost. I had to have quite a bit chopped off after seeing how many split ends I had
I didn't return for another treatment because I decided to grow out my afro over the next year. But It was well worth it. I loved most things about the treatment.
