Make eyebrow hairs grow back?

I guess I over plucked my eyebrows and I have a bald patch on one of my eyebrows where they wont grow back and I have waited 5-6 months and there is still nothing growing back.

Is there a product or a procedure to fix this?
Update: Can you do microblading for just a small patch on an eyebrow without having to do microblading on the entire brow?
