My own experience is I found a really good stylist and colourist at my local Toni & Guy.
Been going for years. Costs me circa £130 for full head of highlights plus cut and blow dry.
I've never had a bad cut or colour.
To be clear I'm not advocating T&G per se, rather than the experts I book with there.
Anyway, I was lax about appointments and needed my hair done for an event and couldn't get a booking.
I went to a well regarded local salon, not a "chain" (good reviews). Cost me half the price of T&G.
Tbh the cut was fine. Not as "sharp" or quite as easily maintained at home, but for half the price it was about 85% of the quality, if you get the drift and I don't think anyone bar myself would have noticed the difference.
The colour was another story. The highlights weren't as fine and natural looking and the colours chosen weren't as flattering. It was half the price but only 10% the quality.
I went back to T&G and my usual colourist to have it corrected as soon as possible.
So my view, based on that experience is a good colourist is damn well worth the money, but a perfectly acceptable cut is easier to find at mid range prices.
