While I agree with the supportive comments others have made, may I humbly suggest you keep in mind that not everyone will be as supportive. In most cases it won't matter, but in some cases these people may have some power over you.
For example, it would be a shame if you were to miss out on a job you were well qualified for because the interviewer didn't like women with buzz cuts. (Stuff like this shouldn't happen, but unfortunately it still does.)
Of course you have to take into consideration how such a haircut/style might affect your job, but other than that, I don't think anyone's opinion but your own matters. I honestly fail to fathom why some people care so much about another person's image; how someone is appearance-wise should not phase others at all, never mind in a negative way. No harm or offense is being caused and those who think otherwise are just simple-minded. Providing an individual does not have anything like Alopecia hair will grow back, so if you do ever tire of a certain look that's fine, but it really wouldn't be that a big of a deal.
