Hi, I am 19 (F) & my friend 20(F) been friends over 4years throughout high school + now college. I dye my hair very often & have tried probably every color under the rainbow. She always felt impressed how easily and perfectly I’d dye it. One day we were talking about her hair and how she hasn’t dyed it for a while. She has black boxed hair for past 2years and wanted to go platinum blonde with blue underneath. I did let her know I would be there to “help” not completely dye it. I did let her know I haven’t dyed anyone else’s hair other than mine upfront. She still insisted we should do it. We bought stuff together from a nearby beauty store and then I took her to my place to dye it since she wanted it to be a surprise to her parents. We did two rounds, but after the first I let her know she shouldn’t keep it for more than recommended time but she didn’t listen to me. Once we washed it off we noticed some of her hair started falling off and looked overall really damaged. I didn’t know how to just fix it on spot since it never happened to me. However, her hair did turn out a pretty blue color + the blonde might be a little patchy but she said she didn’t mind it. She looked really upset. Though, she said she’d give me a gift card for the hassle (which I wasn’t expecting, so that was fine) but now she’s all cold with me. I also apologized after she left and sent her a few products that can repair the hair. Now, she seems mad at me and I also feel guilty since I was the one applying all the bleach & color. Am I really the asshole here? Edit/Update : she finally broke the silence and told me I made her feel “hopeful” by offering it in the first place and I should’ve just let her know that it’s difficult to achieve from black to platinum and should’ve suggested a lighter brown instead and blaming me for not knowing it all since I have dyed my hair for so long and overall, how she’s disappointed at me for ruining her hair and I should pay her to fix it in the salon as well as making her “mentally depressed”
