I have been going to Katerina and Demetra for over 6 years! Absolutely love them, everything they say is 110% true, All their products are straight from Europe, natural and great to keep my hair thick and beautiful. I decided to change it up and go to a friends salon for a couple of highlights for cheap and I really saw a difference. My hair was FRIED, thinned out and bleached. I went back to DK to get it fixed and they did a phenomenal job, my hair has its shine restored and looks much healthier. You definitely get your moneys worth!!! I rather pay to have my hair looking healthy and shiny like it does after leaving DK than going to a cheap salon for 100 dollars and have no hair at the age of 50…. Not only does DK do a great job coloring, cutting and styling hair they also explain what they are doing and why. I HIGHLY recommend DK Hair Studio!!!
