I have long, thick, coarse, and frizzy hair. I started using Kitsch about a month and a half ago and I can’t get enough of their products. The Satin Pillowcases keep my hair fresh and frizz free. I wake up with the curls from the morning before just as fresh as when I took the Heatless Curlers in Satin out and let them flow down my back as beautiful as ever. You must try their products including the Satin Pillowcases.
