Yeeey! I'm happy for you..
It's hard to say if and when the hairs will grow back. If you've been losing hair for a long time it's possible that the hair follikels are dead and will never grow back a hair. If you've been losing hair for only a short period there might be a chance it will grow back. Make sure you massage your scalp. Many woman found that emu oil helped with regrowth. Also you have to take Biotin supplements. You need to take at least 5000 microgram a day. Make sure you eat a LOT of protein and only a little carbohydrates.
Yesterday I noticed that I have some regrowth. Little hair sticking out in every direction! I'm only on a low carb/high protein diet, 1500 Met and I exersice 3 times a week. Not sure what caused the regrowth. I'm also going to get some emu oil and Biotin today. Ooh, make sure you take lots of multiVitamine and some vit B supplements.
Good luck.
