You can buy the whole coppola kit on line at brighton whole kit is a round $500. shampoo, conditioner, keratin and flat iron. It has enough to do 20 plus treatments! I know a few people that do it themselves after watching their stylist. It is pretty easy. The directions are included. My hair stylist uses my kit I bought, and I just pay for time. Around 80-100 bucks, instead of $ it pays for itself pretty fast. You can go in on it with a friend or family member too! Do the math, it is a no brainer! Doing it yourself saves you a ton and is actually not that hard if you understand how to do it!
