Before bleaching my hair, I used to use this to lighten my hair.
It had a lovely coconut scent to it.
For black/brown hair, it will lighten it slightly to dark brown with a reddish tone.
These days I will use it on the yellow tones of bleached hair to make it blonde.
The brilliant thing about this product is that you just spray it on your hair and go out in the sun or use a hairdryer to lighten your hair.
