There are several chain barbershops in Kaifeng, which are slightly larger than regular shops. You can consider them.

1, pretty baby

2. Silk leno

3. Zhang Hong

4, flaunt

5. There is a hutong to the east in the middle section of Madao Street. I forgot my name. Not bad.

Ps: It's not that the others are not good, but these ones are more secure.
