I paid a ridiculous amount of money trying to get my hair colored from black to grey. Jeffrey was confident in doing it in one shot. I should have known that this is not possible. Other stylists in the salon were skeptical while he was doing it. Not only was part of my scalp burned from being left under a heater with the bleach, but it was absolutely over processed. I went home that night and wet my hair only for it to turn into gum. I emailed the salon about my issue. The owner, Tony was very very nice about the whole thing. They offered some conditioning treatments but my hair was ruined. Horrible color that never got fixed and had to pay again for the attempt at a color fix (that was horrible). I ended up cutting all my hair off (literally almost shaved to the scalp) and getting it dyed back to a dark color to cover up the grey/ash color at a different salon. Many of the other stylists may be great at coloring. Just avoid Jeffrey when it comes to color. He may be good at a haircut but that's it.
