Laser Treatment Results Based On Hair Growth

To understand how the laser hair removal treatment prevents hair growth, you first need to know how the hair itself grows.

Stages Of Hair Growth


The Anagen

This is the active hair growth stage. When in anagen, the bulb (bottom of the hair follicle) is locked together with the dermis, and blood is supplied via the active dermal papilla.


The Catagen

This is when the hair follicle starts aging and then finally dies. This is also known as the transition stage.


The Telogen

This is the stage when the remains of the bulb are inactive and the hair falls off. This is also called the resting phase.

How Does Laser Hair Removal Really Work

The light rays in the laser beam are converted into heat. This is what makes the laser hair removal method work. The pigment in the hair attracts the light. That is why laser hair removal treatment works perfectly for those with dark hair. This pigment then converts this light into heat energy. It is this heat energy that affects the hair follicle and prevents hair growth. To cause damage to the hair follicle, the bulb is targeted, thereby preventing the supply of blood and oxygen to the hair. The cells which also allow for hair regeneration are destroyed. All these are achieved by the heat energy from the laser light. The darker your hair is, the lighter your pigment will absorb. As a result of this, waxing or plucking your hair before applying the laser hair treatment is not advisable.
