laser hair removal

Laser hair removal is a permanent form of hair removal that damages or destroys hair follicles. If the hair follicle is damaged but not completely destroyed during laser hair removal, there is a high chance that the hair will regrow. Therefore, many doctors now regard laser hair removal as permanent hair removal, rather than permanent hair removal. Want to know the principle and durability of laser hair removal?

What is laser hair removal?

Laser hair removal is the use of a laser to target the pigment in each hair. The laser travels down the hair, to the root and into the follicle.

The heat from the laser destroys the hair follicle so that the hair does not grow back.

Hair follows a unique growth cycle, including resting, shedding and anagen phases. Shortly after depilation, the hair is in a dormant stage and cannot be identified by a technician or laser. Therefore, in order to continue hair removal, you must first wait for the hair to grow back.

For most people, laser hair removal requires multiple treatments over a period of 2 to 3 months.

How long does laser hair removal last?

Laser hair removal is permanent when the follicle is dead, and if the follicle is simply damaged, the hair will grow back. The length of time for the hair to grow back depends on each individual’s unique hair growth cycle. Some people’s hair grows faster than others. Hair in the resting phase grows slower than hair in other phases.

Do skin tone and hair color affect hair removal results?

People with light skin and dark hair have the best hair removal results. Because of the large pigment contrast between the skin and the hair, the laser can easily locate the hair, enter the hair follicle, and then break it.

People with darker skin and lighter hair may need more hair removal treatments and grow back more hair.

In order to remove hair permanently, the technician must know how to align the hair and choose the correct type of laser. For people with darker skin tones, lasers with longer wavelengths are best for hair removal.
