How does laser hair removal work?
To understand how our advanced laser technology helps clients achieve their desired results, it’s important to first recognise that hair growth follows a cyclical process. At birth, our bodies contain approximately 5 million hair follicles and each follicle is constantly cycling through one of three distinct phases of hair growth. These phases are:
Growth phase (Anagen) :
Transitional phase (Catagen) :
Resting phase (Telegen) :
Laser hair removal achieves hair reduction through a process known as selective photothermolysis, whereby light energy from the device is absorbed by melanin (pigment) within the hair. This energy is converted to heat, which damages the hair follicle and impairs its ability to produce hair.
Over a series of treatments, hair in the active growth (anagen) phase can be effectively targeted, leading to a progressive reduction in hair growth. As hair follicles exist in different stages of the growth cycle at any given time, multiple sessions are required to treat hairs as they enter the anagen phase, when the laser is most effective.
While many follicles are significantly damaged, no laser hair removal device can guarantee permanent removal; this is as, follicles may recover over time, and previously inactive (dormant) follicles can activate. Hormonal influences may also stimulate new hair growth. For this reason, maintenance sessions are recommended to help sustain results and manage any regrowth. The number of treatments required varies depending on individual factors such as hair type, skin type, treatment area, and hormonal influences.
