As ONC NATURALCOLORS do not contain chemicals to open your hair cuticles. After the color mix is on your hair. Use medium heat from a towel, hairdryer, or our Thermal Heat Cap
. This opens the cuticles so the color can go into your hair. Only use heat on the roots or regrowth hair. The Thermal Heat Cap is healthiest. As it opens the cuticles using trapped heat from your head. It also prevents overheating, which dries hair out. Don't forget - USE HEAT!
 
Men do no need to use heat.


The ONC Thermal Heat Cap holds body heat and helps to open the hair cuticles to let color in. Its use does not ensure color results.
