Thanks for your feedback on your recent order. Its a shame to hear that you were not satisfied with your results.
Our products are specially formulated to eradicate yellowing tones in white or grey hair. However, there are lots of other factors out of our control which can cause this to happen. For example, yellowing can be caused by spending time in the sun, by using other products that contain harsh chemicals or pollutants, and even by using heated hair appliances such as straighteners or tongs. These can all cause your hair colour and condition to alter, but please be assured the build up of yellow will not be due to using our products.
Thanks again for getting in touch.
