Will Hair Grow Back After Accidental IPL to the Hairline?

I have been doing IPL treatment on my face and after the second treatment, the technician accidentally went into my hairline and I am missing volume from the sides around the hairline. She burnt the hair around the edges and it has changed the shape of my face. I'm noticing the hair is becoming thinner - where I had a few scraggly hairs left, they have now fallen out. Please tell me if my hair will grow back. Thanks
