how to darken coloured-treated hair naturally?
I recently got my hair coloured to a deep golden brown. I had jet black hair prior to this and had to be bleached before being coloured. However, even though the colour has turned out well, I feel its too light a brown for my skin tone and stands out too much in the sun. Is there a way to turn it into a darker more natural brown naturally? Ive heard that coffee and walnut water works well?
