Do girls working in the hotel industry have to have long hair?

It doesn’t matter, this has nothing to do with work.

Who says women have to have short hair? Personal hobbies.

Unless you are a model or something and pay attention to appearance, then it’s up to you.

Your failure to find a job cannot be attributed to your short hair. There must be something else that makes them dissatisfied. They are finding fault with your short hair. You must believe in yourself. Only by being yourself can you do what you want to do.
