I had a years worth (12 sessions) of laser hair removal on my face. Is there any chance to grow it back? (photos)

It sounds like you had a good reaction to laser hair
removal. And yes it is "permanent reduction" of hair. The hair that
does grow back tends to be finer hair. You may grow some hairs back over
time,but exactly how much will have to be determined over time.

Laser hair removal is permanent reduction over time. Most of those hairs will not grow back, but some might. It also will depend on the type of laser used and the skill level of the provider -- 12 sessions with your skin color and facial hair is a little unusual. So now you need to wait -- and see what will come.

When a follicle reacts to laser hair removal in a positive way, that means the follicle is destroyed and cannot produce hair anymore. However, we do always say that new hair follicles will develop over time, that is why it is called "reduction". These will be few and far between, but they do develop. Laser hair removal requires maintenance to treat these new follicles, assuming that's what you want. So, you cannot regrow hairs that have been permanently affected ever. But you may get a few new hairs from time-to-time as follicles develop. "This answer has been solicited without seeing this patient and
