Stargazer's range of semi-permanent hair colour allows you to achieve a wide range of vibrant colours. The dye is conditioning & can be applied directly to the hair through the specially designed bottle. The dye is free of ammonia & peroxide. Stargazer hair colour can be applied to natural, dyed or bleached hair (please note that the hair colour will not cover white or grey hair). The dye is gradually washed out with every shampoo of the hair & lasts for approximately; 20 + washes on Bleached hair, 15 - 20 washes on Blonde & other Light Coloured hair, 5 - 15 washes on Darker hair. Individual hair types will lead to different times but the above figures are an approximate guide. Each box contains instructions in eight different languages & pair of disposable gloves are included for your use.
