i just dyed my naturally light/medium brown hair dark brown. it turned out much darker than i wanted to (almost black) and i can't stand it. i was wondering if i can get it a few shades lighter somehow and how soon i can dye it again?

This is a common problem. When the hair is porous it tends to soak up too much. Shampooing the hair with a clarifying/deep cleansing shampoo will lift some of it out. With every wash your hair should get lighter. Remember to use a conditioner after though as it will dry out the hair.

Also some members on here used head and shoulders to fade out colour and it worked for them, so you can perhaps try that too. Good luck. :)

You can dye it again in 4-6 weeks or your can get a chemical dye remover at some drugstores. But the remover olny works on unbleached hair.

Thank youuu!
