Laser hair removal removes the hair completely from the follicle.. so there should be no stubs.. some people have hair that grow back but it most cases it's very smooth
What's the difference between waxing and laser hair removal?
Laser hair removal uses a laser to "kill" the hair at the root. It can cost thousands of dollars and demands multiple treatments. It all depends on the area and thickness of the hair you are trying to remove. It can also lead to permanent scarring and adverse skin reactions when not done properly.
Waxing uses a hot (or sometimes cold) wax applied to your skin and a linen strip to rip the hair strand from it's follicle. It is not permanent and requires nearly monthly trips to the salon. It does have quicker results though. About the worst things that can happen are burnt skin and allergic reaction.
Waxing costs less per session, is way more painful and is temporary.
Laser is more expensive, hurts some and is permanent. You generally need 5-6 treatments to get all of the hair.
