Keratin Treatment- First, we begin by clarifying the hair throughly to remove chlorine, impurities and sprays, etc. Then, we apply the actual keratin section by section and process for 20 minutes. Finally, the keratin gets flat ironed into the hair. The results are unbelievable! The hair is totally frizz-free, smooth, and shiny. It lasts for 2 – 4 months and it can be done again.
