100% agree. I put a post on a couple of weeks ago on a thread similar to this...
I will never be going to a hairdresser again, ever, for anything. Not a cut or a colour. Nothing - ever. Pre pandemic, it was roughly 15 to 18 pounds for a dry cut in the two hairdressers in my market town. (By the way, there isn't another hairdresser for 18-20 miles. So I don't really have much choice, unless I want to do a 40 mile round trip. And even then there's no guarantee they will be any cheaper.)
I didn't go to the hairdressers from Spring 2020, all of 2021, or the first half of 2022, as I was shielding a bit more because of health reasons, and got a bit paranoid about being in close proximity to people. So I got used to trimming and colouring it myself.
Also, they were closed much of the time because of the pandemic. So that was a another reason for getting used to doing it myself.
Last Autumn (October,) was my niece's wedding and I thought I would quite liked a 'hairdresser' cut, as I've just been trimming and dying myself for about 2 and a half years.
Contacted the hairdresser back in early October last year. They said a dry cut is now 67 pounds. 67 pounds! I said, 'well, how much is it for a wet cut, or cut wash and blow dry?' They said a wet cut's the same as a dry, and a cut wash and blow dry is 80 pounds- so I 'might as well have a cut wash and blow dry really.' So they're trying to make out that a cut wash and blow dry is actually good value, Cos it's only 13 pounds more than the dry cut. 
The cut wash and blow dry used to be £30! (Pre pandemic.) I tried the other hairdresser and they said it's roughly 50 to 65 pounds depending on how long the hair is. I said 'mine is roughly shoulder length.' She said 'Hard to say. It could be anything from 50 to 65 pounds... maybe more We won't know until we start cutting it!'
So basically I will be sitting in the chair spending half an hour while she does my haircut, not knowing how much is going to cost at the end.
People can say, Oh yeah, it's all the extra costs for materials and rent and electric and heating and so on. But the fact is my husband went to a barbers shops just two or three weeks ago, (one in a shopping centre in quite a big town.) They spent 35 minutes doing his hair and did it beautifully. They charged him 18 pounds!
So I have absolutely no idea why the two hairdressers in my little market town are charging so much. I imagine many others are the same (for womens hairdressers!) Suffice to say, though, I will never be going again. Until the day I die. I'll just be doing my own hair. I'm just gonna have to carefully trim it and layer it, get the split ends off, and just dye it myself as I have been doing since Spring 2020.
Like hell am I paying nearly 70 pounds for a trim. And by the way, they now charge £200 for highlights compared to 70 to 80 pound that they charged pre pandemic.
I'm not being funny, I have to be careful, but I can cut and trim and colour my hair myself. I don't want to demean the profession, (and I know I am doing,) but they are cutting and colouring hair, they're not doing heart or brain surgery. Basically it's something I can do myself, and I will be continuing to do it from now on. The rise in costs for WOMEN'S hair is outrageous.
And it's no good people saying 'go to the barbers.' They won't do womens hair, they don't do womens hair, and many of them CAN'T do womens hair!
