The colour result will depend on your natural hair colour. Results may vary on previously coloured hair. Read and follow instructions before use. This product is not intended for use on persons under the age of 16.
Followed step by step instructions couldn’t see any change after the recommended time scale so left the product on for a further 30 mins. No change although my hair still has the stench of chemicals. I have bleached blonde hair in different tones. It has started to grow out quite a bit so fancied to brighten it up a bit. I also have greying hair. Nothing has changed.
