My students have all kinds of piercings, ears (multiple), nose, eyebrow, lips, tongue, between their teeth, navel and I guess other places too.
They also have all kinds of haircolouring, from bright red, pink, green to blue.
Some have tattoos visible on their arms or hands.
No, I personally don't like it looking like a christmas tree, but times have changed.
My own daughter looks pretty weird to me with her pink hair and nose and navelpiercing, but well, I looked pretty weird to my mum with my "big hair" looooooonggggg time ago!
I hope,they are going to be good nurses, no matter how many piercings, tattoos or haircolour they have.
