At first a local anaesthetic cream is applied to the skin. The hair follicles are now ready to receive the tiny laser beams. Upon contact, the energy delivered by the laser beams begins to accumulate. Intense heat is transferred down to the follicle which produces the hair. It is extreme heat that causes the destruction of the hair follicle.
Most patients feel heat with a combination of the sensation of a pin prick.
It is common to notice hair growth within the first few days after the laser treatment. But the hair will soon fall out. You may need some plug-ins to view the animation.
