Barbers and Hairdressers are Very Different
I'm surprised this hasn't been mentioned, but in the US at least, barbers and hairdressers have very different qualifications and licenses for historical reasons. Visible differences are barbers use sharp implements without guards, e.g, they shave people with straight razors, and use clippers freehand where hairdressers use guards of various sizes, and of course hairdressers do much more than just cut hair.
Also, barbers display a barber pole in front of their shop.
I'd like to see shop=barber
I support this. In Ghana there are many hairdressers and many barbers. The barbers only cut your hair whereas the hairdressers only braid hair and do other stuff with it.
Switch combination suggestion from booking=* to reservation=*
reservation=* and booking=* are largely duplicates of each other. reservation=* has about 2200 instances, while booking=* has about 300. The wiki page for reservation=* dates from 2011, while the page for booking=* is from 2018.
Both keys take a mostly overlapping set of values.
Within the context of hairdressers, the term reservation is also used colloquially.
There is no tag whether children's hair is cut. I think not all hairdressers do. (e.g. some does not have the high chair.) There are 116 instances of children=* and 103 of child=* but I don't know in what combinations/context they appear. I can't find them under combinations of shop=hairdresser on TagInfo.
