I had a hair removal session done on my chest, now hair is thinner. Will my hair eventually grow back as it was before?

I had a single session done on my chest months ago. The remaining hair is now much thinner and lighter and some spots look almost bare. I changed my mind and don’t want to pursue the treatments. Will my hair eventually grow back as it was before? If so, how long can it take? If not, I could have a single session on my pubic area so that it matches better with my body, is that a good idea? Thank you!
