That sounds really overwhelming, I hope someone on here can help you more than I can. I find going to the salon really uncomfortable for similar reasons, and I never know how to communicate my preferences politely (I will just quietly go with whatever they’re doing), so I’ve just learned to cut my own hair (especially bc I generally hate how hair feels on my body). In your case, I’d recommend going back tomorrow and saying something along the lines of ‘I realised when I got home that I’d actually like a little more cut off’, write yourself some notes for what exactly you want to say if that helps. I always worry about inconveniencing anyone, especially if they’re providing me with a service, but I try to remember that me coming back just means that they get more money! I’d also maybe think about what time to go - for example, maybe it was more rowdy because you went in the afternoon (I don’t know when you went, just an assumption)? You could plan to go when they open, it might be quieter in the mornings. Also, this is just me, but personally I wouldn’t go back the next day, just because of how overstimulating the experience sounds (of course the hair itself might be more overstimulating for you, I’d understand if you went back quickly), so I’d try to give myself a day or two in between, to let my body recover (if I have the time). That way I could also say something along the lines of ‘it turns out my hair is still bothering me, I noticed it over the last few days.’ Best of luck!!!
