I just had the Keratin Complex Progressive Straightening put on by Master stylist Charles Farlow and it is the miracle elixir of the gods. It is a miracle product that has changed my life. I have naturally thin and curly fuzzy/frizzy hair and the Keratin Complex has taken out all the frizz and left it shiny, straight, lots of body and 100% easier to manage. It looks awesome. This product is amazing. If you have been fighting frizzy/curly hair you have to give it a try. Charles is a genius at the application. Its not a chemical, it leaves hair healthier than before and it is inexpensive compared to the thermal reconditioning..which definitely causes damage and breakage. I even have a headful of highlights and my hair looks as healthy as when I had virgin hair. It's progressive so your hair will just get better and better with each application. It lasts 2 to 3 months. I swear by this product and will keep doing it forever! Try it! You will totally love it!
