Im a 32 Years Old Man Who Did Laser Hair Removal on my Beard and Now I Want It Back What Can I Do? (photo)

i did laser hair removal with the light sheer six years agoon my facial hair when i had full beard...and its dark hair...now i have very little hair and patchy spots... and i want to bring back the beard ...will the facial hair ever grow back on those patchy spots? is minoxidil can help for that? or is this hair gone forever?
