It doesn`t lighten my hair. It`s too dark. I remember putting lemon juice on it as a teenager to try to get some trendy beach bum streaks but to no avail.
Your skin produces more melanin when exposed to sunlight, the melanin doesn't darken, it is already dark. Hair lightens because the melanin in the hair is bleached by the sunlight and cannot be replaced because the hair is dead keratin.
