## Description

Revolutionary hair colouring kit - naturalcolors Two-Step colouring process provides a natural, healthier choice for permanent coverage of grey hair. Salon developed, this process provides rich colour without the risks of Commercial, chemical-laden hair colour dyes. The unique process involves applying heat to open the hair's cuticles instead of unhealthy ammonia. Once complete, you're left with the smooth, shining, luxurious locks you've always longed for.

Review: ONC Naturalcolors - I love ONC NaturalColors! I am unable to use most hair color because of chemical sensitivities and allergies. This product does not irritate my scalp or bother me in any way. It also covers my gray completely! I had used henna for several years because it is a natural product, but it made my hair dry and brittle over time. Henna is difficult to color over, but the ONC colors that I chose (6N and 6KR) covered my gray and blended perfectly while the henna grew off. Because some hair color can cause henna treated hair to literally dissolve, I researched natural hair color extensively. I am so glad that I found this one! After 6 months of using ONC my hair is healthier and shinier. If you are covering gray, definitely use an N or mix a color with an N. I tried 6KR alone first and it did not cover all of the gray. Also it seems to cover best when my hair is super clean with no products or conditioners in it. I hope this is helpful! Not all products that say "natural" are truly natural. I believe this one really is and it has been a great investment for the health of my hair. ~ Julie

### ⭐⭐⭐ Lessons learned
*by J***H on 17 April 2021*

I have been coloring my hair for years with professional color and wanted to try something more natural. I’ve never used box color before and I have to say, I’m not impressed. Here are a few things I didn’t know about this product and wish I had: 1. Measuring - the instructions say you can use leftover color later (indicating you can use less than the full amount) but none of the materials provided in the box have markings or graduations so you can measure anything. I have a kitchen scale I used to try and measure the components into the cup they provide but the amount weighed did not match up with the amount the bottle says should have been in the bottle (1.7 oz). How are you supposed to use part of the ingredients or combine them properly if you can’t measure anything? Also, the grey coverage instructions call for specific amounts of color and fixant - again, how do you measure this? 2. Grey coverage - I got the 6N color as well as the 6KR so I could do grey coverage, as the website says. But the instructions say to combine 1 oz color, 1 oz grey coverage color and 2 oz fixant. This made way too much for the roots and left only 0.7 oz (theoretically, though far less in practice) for the rest of my hair, which is long. Needless to say, I ran out of color with just one box and couldn’t color much of the rest of my hair. If you plan on doing grey coverage at the root and mixing a separate amount for the rest of the hair (as the instructions say), you will need 2 boxes of your desired color. 3. Amount of grey - the box provides instructions for if you have over 40% grey. I am entirely silver. As a result, I did not get a nice auburn red-brown color (or anything close to what the box color said it would do). I guess I should have known that but there were no instructions or suggestions for how to handle mixing colors if you have no pigment on your hair. As it is, my roots turned out orange which also doesn’t match the rest of my hair color (and there wasn’t enough left in the bottle to cover the rest of my hair anyway). I wanted to like this but it just did not work for me. I’ll be going back to professional color with a stylist.
