How long will it take for my eyebrow to grow back?

So today, I was pretty nervous and my mind wandered off somewhere and I just randomly started pulling out my eyebrow hair. After a while I realized it and I had a weird feeling already so I went to the mirror to check it up and geez... I had like 2 little holes in one of my eyebrow. It looked horrible. I tried to cover it up with my mom's eyebrow powder and a bit of eyebrow pencil. It didn't look bad then. The eyebrow's shape is intact and the holes are really small, I lack just a few hair but I still need to cover it. It happened for the first time so I'm not afraid that it won't grow back anymore. I only want to know how long will it take, in your opinion? Thanks in advance :)
