I shaved my eyebrows a couple years ago they grew back but I ended up getting dermatitis that is now cured but now they fall out on their own, help?

See doctor. You may have a medical condition which causes you to lose your eyebrows if the hair is still falling after the skin rash has subsided.
Culture for MRSA. Most common infection in plucked eyebrows is MRSA (methicillin resistant staph aureus), a superbug once limited to hospitals and nursing homes is common in the community setting. See your doctor, and you might need a consult.
