I have been getting my hair Japanese straightened by Yuki for several years, usually right before the summer. When I lived in NY, I really needed it because the humidity would make my hair unruly and frizzy. I have never tried the Keratin treatment (Brazilian straightener) because it contained formaldehyde. I was so happy to hear that now there is a less damaging version of the original Japanese straightening product that is safe to use on highlighted hair. It's by Milbon and called Liscio Crystal Highlight Smoothing formula. I asked Yuki who is now at the Pierre Michel salon to go through the steps with me so that I could share his magic!
