can you only use that sun-in hair lightner stuff in blonde hair? or can you use it in brown hair too?
being a hair stylist. who once upon a time I used it. you can use it in brown hair but on blonde I recommend that you put it on while your hair has been previously shampooed and is still wet. email@example.com
you can use it on any hair colour I think it just sun bleaches hair and lightens it so if you use it on brown hair it will make it lighter
it turned my mom's friend's hair bright orange, and she had brown hair. I'd reccomend not to use it.
