I had one laser hair removal treatment on the back of my neck and want to discontinue treatment. Will my hair grow back normally

I had my first laser hair removal treatment on the back of my neck just over a week ago. Most of the hairs have since fallen out and the skin is fairly smooth. I've decided that I don't want to go through with the rest of the treatments. Will the hair grow back normally after one treatment or will it grow back sparsely or in patches? My skin is pale and the hair is coarse and dark. Thank you for your responses!
