I gave myself eyebrow slits with a razor and I want to know if the hair I shaved will grow back?

I shaved slits in my eyebrow and I plan to keep them for a year but I'm scared that if I choose to keep shaving them and plucking around the place I shaved that it won't grow back. Sometimes the razor doesn't get some hairs I wanted it to so I have to tweeze it,this is in the arch of my eyebrow where my eyebrow hair is most thick. Now I'm debating whether or not I let them grow back now before they stop growing back or if I can continue to shave and pluck them every week or so for another year?
