I see you are using StreetComplete.
You might be interested to know there is a new function in StreetComplete that makes it easy to add shops yourself.

Go to the "☰" menu, then select Overlays, then Shops.
From that screen you can select the location and click on the "+" button at the bottom.

For hairdressers, one very important detail to know every time is if they accept women, men or both.  I found their website and from the description and pictures it is probably a women-only hairdresser here.  If I am mistaken, please change it or reopen this note.

Happy mapping.
