This is the only place I will trust my hair color. I am using Rodolfo Valentin hair colorists group since the past 3 years I can ensure that they are the best hair colorists in the city, no matter who does my hair. I prefer Pia but if she is not there because she is busy in their Long Island location or at their hair boutique, then I use any of the others hair colorists, always good, always same results, they follow the computer formula and they share same techniques. Worth it very single penny. By the way they are more affordable than the other top hair color salons in New York which much better service.
