Is a Buzzcut/Being Bald Considered Unprofessional?

Like many other guys in their mid-20s, my hair is beginning to thin and fall out. It's not enough to warrant a full buzz just yet, but I am curious as to what to do in the future.

I do two arubaitos, and I'm wondering if it will be unprofessional to get a buzzcut or shave my hair clean.

I also plan to start job hunting in the near future, so I'm worried it may affect my employment chances as well.

Do you have any experience with this?
