Lisa applied the Keratin Complex smoothing system to smooth down the curly, frizzy hair that I've struggled with all my life. It's FANTASTIC! It was 2 months ago and my hair remains smooth, straight, beautiful -- just like I was born with it! It's so much easier to deal with now. I can just wash it and quickly blow it out, it remains smooth, almost completely straight with just as much or little of a gentle curl at the bottom as I choose to style into it. I finally have the hair I want!
