Use of heat is necessary for results


As ONC NATURALCOLORS do not contain chemicals to open your hair cuticles. After the colour mix is on your hair. Use medium heat from our Heat Cap or a hair dryer. This opens the cuticles so the colour can go into your hair. Only use heat on the roots or regrowth hair. The 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. Apply. Wait 30 minutes for full grey coverage. Or 15-20 minutes for a 'salt and pepper' look. Rinse.


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