Easy Preparation: - Put gloves on - Open cap of the developer bottle and pour the contents into a non-metallic bowl. - Pierce the seal of the Cream Hair Colourant Tube with the point in the cap and squeeze the entire contents in the non-metallic bowl. - Mix the colourant and the developer with a hair colouring brush and stir well till the mixture is smooth in texture. Apply immediately. Easy Application: - Keep your gloves on, apply the mixture to dry, unwashed hair. Start by applying the mixture to the roots, making sections separating the hair, strand by strand. - Quickly spread the leftover mixture through the rest of the hair. - Ensure that all of the hair is covered by the mixture. Pile the hair on the top of the head. - Leave to develop for 25min (35min if your hair is resistant or if you have over 70% grey hair).
