Shaving head to bald - do I go to a barber?

I’d been colouring my hair for yonks and had just managed to grow the colour out, revealing all the grey, when I lost my hair after 2 weeks of chemo. But although it grew back white at first, it finally settled a lot less grey than before, a ridiculous process to get a natural colour hit! But as @kmakm says, take it when you can!
