Thanks @Kitten_Pajamases!! I actually did this the other week (wanted to take a before and after and totally forgot…d’oh!) and it frikken worked! Was I super scared? YOU BET haha, but you know what? It’s only hair and it WILL grow back, plus my hair is already light, so there was not much that could’ve went wrong!
I actually applied the hydrogen peroxide to my hair and laid out in the sun for about half an hour! I got the cutest highlights ever and saved so much money in the process!
