In an Islamic country, such as Iran or Saudi Arabia, I presume a woman getting a haircut would be a matter of going to a women-only hairdresser.
If I went to get a haircut in China (where I am now), it might be performed by a man, but even if it wasn't, men would see me without my hair covered. I doubt an average hairdresser would have a private area, and even if they did, they might not allow its usage.
Question: How can a woman get a haircut in a non-Islamic country?
