yes, significantly more expensive, to the point where I would do a DIY ponytail chop for a few years
and home dye (until DH begged me to stop; apparently his OCD could not handle the uneven layers)
name brand salon 2023:
Haircut : starts at 300 (starts at 450 by owner)
highlights: starts at 300
single process: starts at 175
gloss: 75
blowdry: starts at 85 (package rate)
boutique salon, in 2008: haircut: 125
highlights and single process: 250 (as per my recollection)
gloss: maybe 40
in both cases, various services are staggered as needed (usually not all at a time)
not including regular tips or holiday or birthday tip.
prices are USD, NYC
ETA: I find that just like a regular omakase sushi place, if you go to the same place regularly for cut, color, and other services, the rates can be less than published, but the price reductions might fluctuate or be a bit opaque. For the significant number of clients that go to different salons for cut and color, I believe they tend to pay published rates. But this is just my anecdotal observation over the years.
ETA: for my best friends daughters high school graduation, I gifted her the works (including a mani pedi). total cost 1K USD Excluding tip. The salon did ask if she was over 18, perhaps bc of color, IDK. But, apparently she has a lot of hair and the salon had so much fun with her that they spent about six hours and made her feel like a princess. ( She was able to take advantage of this prior to prom so it was especially appreciated). they also gave her the color info they used, so she could have another stylist help her in her college town.
