Can LLLT be used to promote facial hair density on existing follicles after they have been damaged from laser hair removal?

At the age of 19 I started getting laser hair removal on my beard because it was very corse and dark. Although it was nice at the time, now that I am 24 I miss my thick beard. Some parts on my face no longer have a follicle left and then there are hairs that were unaffected by the laser (chin area). However, I would say about 80% of the hair has regrown since I stopped LHR. Unfortunately they are very very thin, and grow slower than my corse chin hairs. Can this be reversed?
