ONC Thermal Heat Cap traps the heat that comes out of the top of our head. There is no need to plug or microwave it. The heat that comes from the body is more than enough.

Durable, reusable heat cap designed to be used for applications that need that extra boost of heat. Keeping color in the cap and on the hair, it allows free movement without the worry of color dripping or making a mess.

The heat cap was originally designed for professional lines use. You can use other methods, e.g. cover the hair with foil and use heat from the sun, use a shower cap and hair dryer or a standard salon hair dryer. The cap makes any process or application that needs heat much easier, allows you to move freely without worrying about any mess, and helps to deliver more professional results.

Safe and convenient to use the ONC Thermal Heat Cap is designed for use with ONC hair color dyes and is ideal for nursing your hair at home.

      LOVE ONC Thermal Heat Cap

      I love this heat cap.

      It is very easy to use and I have used it not just for hair color but conditioning treatment as well.

      It is MUCH easier to use the heat cap than to deal with blow dryer while coloring.

      It’s a win!!

      Excellent product!

      My hair is extremely happy with your products!
      I did not use the hair dryer ( as you recommended) . Even without this part of hair coloring the final result was great!
      I really highly recommend your company and your hair products!

      Mary Shafer
      Great results!

      I can’t say how different my excellent coloring results would have been without the heat cap, because I read all the reviews before buying it to convince me it was necessary. It worked and I’m happy, and the cost was relatively low to ensure good results.

        How does NATURALCOLORS get into hair?

        NATURALCOLORS has a lower pH compared to chemical hair colors with toxic chemicals. Applying heat is necessary to open the hair cuticle in uncolored hair. To get color into your uncolored hair without harsh, toxic chemicals, medium heat from a hair dryer or a thermal heat cap (sold separately) is needed. These soften the cuticle and allow ONC color pigments to be deposited into hair. It does not damage hair or make it fallout.

        What does 2-in-1 Hair Color and Hair Care in one bottle mean?

        NATURALCOLORS does not have the harsh chemicals other colors have. It has a low pH. Therefore the formula has added vitamins, essential oils, and herbal extracts. These help repair, maintain, and nourish your hair. They would not survive in a chemical hair color. Hence — 2-in-1 Hair Color and Hair Care ... in one bottle!

        Why is NATURALCOLORS' low pH so good?

        NATURALCOLORS low pH does not open the pores of your scalp. So chemicals cannot seep into your bloodstream. When chemicals get in the bloodstream they end up in your liver. The body cannot clean these from your liver. Because the chemicals that make chemical color stick to your hair make it stick to your liver. This is one reason why breast cancer grows year by year.

        Why do I get a decreased demarcation line?

        Unlike Hair Colors with toxic chemical which operates at a high pH, swelling the cuticle to force pigments into your hair, NATURALCOLORS moisturizes your hair which softens the cuticle. This allows it to open at a lower pH and enables the color to wind itself through the layers of your hairs’ cuticle. It only removes enough color to make room for NATURALCOLORS inside your hair. There is no demarcation line. As the natural ingredients in your hair like protein, pigment and moisture are intact. As a result the color fades over time. Whereas all other colors leaves a blank space. Where the natural protein and pigment of your hair is removed. This then replaced by chemical hair color. ONC NaturalColors only removes minimal amount and replaces it with a formula made up of low pH, organic ingredients.
