Will Hair Grow Back After Accidental IPL to the Hairline?

I had IPL treatment on my face one week ago and the plastic surgeon accidentally went into my hairline majorly and I am missing volume in the front of my hair. he burnt the hair and reduced the curls. He was using the machine at level 9. Please tell me if my hair will grow back. I have to buy a wig or integration piece or consider a transplant. I am a 48 year old woman who prior to this nightmare was known for my gorgeous hair. Now I am embarrassed to go out because my hair is missing. Thanks
