Dyed Hair in a Degree Apprenticeship interview?

I have an upcoming in-person interview and my hair is half-dyed blue.
Is this unprofessional or would it be acceptable to keep it? I'm quite stuck on whether or not I should cover it up or if it would be ok to leave it.
Any advice would be much appreciated. Thank you!

I mean hopefully it shouldn't affect your interview because otherwise it would be kind of biased if you know what i mean. From my experience I had dyed hair when I did an interview for an apprenticeship and got the job although it was quite faded out at that point so not sure if it was that visible on camera. It's up to you what you do but self expression is important. Good luck with the interview whatever you do
