We don't make them but was impressed by the fact it was natural, organic, materails no ammonia or parabens and nice colours.. Tested by our co founder Karen
AMMONIA AND PARABEN FREE,IT REDUCES THE RISK OF ALLERGIES. and of course the chemicals linked to cancer
does it work well this karen using 7.3 
can we just say that no hair colourings are without some degree of harsh chemicals they have to be there to work.. it’s a case of using ones which contain the least amount and from what we can see this has very low levels of them compared to many others, in all cases less than 1% of the formulations. also consider that you are applying it to hair which is dead and then it’s a wash off product as well the percentage left is very negligible.
Now we have also looked at the scientific data on much of this and the molecule size of them cannot go through the skin, the data that says many where harmful is when given directly into the body at all very hight levels .
