Apprenticeship programs dress code

So, I know piney point will shave your head, but I have permanent piercings that I can’t take out with out them closing, can I wear the clear spacers? I’m not joining the military, I don’t understand the boot camp lite aspect. Reluctantly, I can regrow the hair, but I would rather not have to go through the process of repiercing scar tissue

If the piercings are a no go, are there other programs I can take to become AB, get higher pay than I would off the street and get guaranteed a job?
