Laser hair removal

Growth cycle and colour of your hair

In order to understand the laser hair removal process and how some lasers can remove hair, it is important not only to consider the structure of a growth cycle of the hair, but also the colour of the hair. Hair consists mainly of a hard protein known as Keratin, produced by the hair bulb, which is situated deep within the dermis.
The colour of the hair depends on the presence of a pigment known as Melanin. Melanin is produced by pigment-forming cells (or melanocytes), which are found in the hair bulb. The ultimate colour of the hair is determined genetically and by the type of melanin produced by the melanocytes.
Hair growth occurs in a cyclical fashion, with an active growing phase, anagen, and a resting phase, telogen. During anagen, the hair is connected directly to the hair matrix in the base of the hair follicle. During telogen, however, the hair bulb moves away from the base of the follicle so that there is a gap between the bottom of the hair and the bottom of the hair follicle.

When to have laser hair removal treatment

The more commonly-used laser hair removal treatments depend on the high level of energy in the laser light being taken up by the melanin pigment within the hair. The melanin converts the energy into heat, destroying not only the hair but the hair matrix and hair bulb at the base of the follicle. The heat generated in the hair follicle is conducted down to the base of the follicle much more readily in an anagen hair (which is still connected to the base of the follicle) than in the resting telogen hair (when any heat generated has to cross the gap to reach the future hair-producing region). This is why most effective laser hair removal occurs when the follicles are in the active anogen growing phase. Because not all follicles are in this phase, multiple laser hair treatments are almost always required.
The best results also occur when there is plenty of target pigment melanin in the hair and therefore white, blonde and grey hair cannot be treated.

How does laser hair removal work?

A laser beam is focused on the hair follicles beneath the skin surface to disable the follicle quickly and safely, and stop the hair from growing.

Will laser hair treatments hurt?

No. Laser hair removal treatment won't hurt and it won't damage surrounding skin. It's suitable even if you have sensitive skin.
