My old hairdresser, before I moved. This problem was mainly caused by me half liking what he did, even though he never sought my consent, and also caused in part by me seeming very exotic to him as a white woman in Asia.
The first time, I went to him with waist-length mid-brown hair that hadn't been properly cut in over a year and left with swooshy boob-length bayalage in warm tones. I loved him!
The second time, I left with a fabulous ash-blonde with really, really subtle blue tones. It was the coolest cut and colour ever.
The next time I went, he straight-up dyed it the exact shade of my blue eyes without asking. I was both outraged and awed. It was darker at the top and then faded to a sort of icey colour at the ends. Totally awesome but completely unasked for and utterly inappropriate considering my job (university instructor). I had to slink around at work until I'd faded it enough. My students adored it though.
The next time I went it was just days after lockdown had lifted, but while we were still teaching online (March 2020). He dyed it a solid blue shade I didn't like. I didn't say anything. It was a weird time.
The next time I went was when campuses had just opened back up and I was leading the graduation ceremony the next day. "Don't dye my hair an unnatural colour, alright?" I said. "I've got a big work thing tomorrow". He agreed and then dyed it a very subtle purple. I did gently express to him that even light purple isn't really a professional colour but it was low-key, so fine.
The next time I went, he took me from long hair to shoulder length and it was just an incredible cut. No colour that time. I forgave and forgot everything. What a stylist, etc.
The final time I went, I brought several pictures of ash-blonde bayalage with a root-melt. My hair was already blonde with some dark roots. Totally achievable. He dyed it pink and blue. I totally snapped and made him try to fix it. My hair was fried. He was sorry. I was so pissed off with him. I was moving away a week later anyway. Shitty way for our hair relationship to end.
He was such a great stylist and a master at bayalage, but he could not help himself but get creative with the toner.
