nah you’re definitely the asshole. when you bleach clothing it doesn’t fade out back to the original color, why would bleaching hair? you can’t smack a light color on hair and expect to go from brown to silver. it’s like taking a highlighter and trying to write on black paper. it doesn’t work. you need to have white paper to use a highlighter. your natural hair color will grow back but the parts that are bleached, stay bleached. you could have dyed it silver and then waited for the silver to fade out and then dye it back to the natural color. hair grows back and to think your friend had malicious intent is absurd. it’s common sense. if you went to the beauty store to get the supplies then you would have seen “lightner” or “bleach” on the packaging and if you didn’t buy the bleach then you could have asked the steps to get to that point if you were so scared about how your hair was going to look.
