How Does Laser Hair Removal Work?

Laser hair removal has become a popular cosmetic procedure nowadays. Thanks to advanced technology, patients no longer have to deal with inconvenient hair removal procedures like shaving, waxing, and tweezing, which require ongoing maintenance.

To provide readers with a better understanding of how laser hair removal works, Dr. Shikha Aggarwal, a well-known dermatologist practicing at Bliss Laser Skin Clinic, has explained the same in this blog. The leading doctor is known for performing the best laser hair removal in Ludhiana.

Let’s understand how laser hair removal works and the three stages of hair growth.

To better understand how laser hair removal works, one needs to understand the different stages of hair growth. There are three different stages of growth, and not all hair grows at the same time. That is why one must have noticed that when one gets waxed a week ago, the hair starts to grow again after some time. Usually, these are not the same hairs that were waxed a week ago. Instead, these are hairs from another follicle that were at a different stage of growth. The three stages of hair growth are as below:

Anagen (active growth phase): In this phase, the hair follicle’s bottom gets attached to the dermis and its blood supply to the dermal papilla.

Catagen (transition phase): The hair follicles get destroyed during this phase and enter the catagen phase.

Telogen (resting phase): The remains of the hair bulb are inactive in this phase, and the attached hair falls out easily.

How Do Lasers Remove Hair?

Laser hair removal works when the laser beam is converted into heat. The light is attracted to the melanin in the hair. This pigment absorbs light and gets converted into heat. The heat then affects the hair follicles and prevents the growth of hair. To destroy a hair follicle, the bulb of the follicle, where the blood provides the hair with oxygen to grow, as well as the stem cells responsible for hair regeneration, must be destroyed. A temperature of around 70 degrees is required to be able to do this.

The more pigment a hair has and the more light it absorbs, the darker and thicker it gets. This is why it is essential not to wax or pluck the hair before a laser hair removal treatment, because if there is no hair there, there will be no way for the laser light to treat the hair follicle.

The light gets emitted and is absorbed by the pigment in the hair, which further travels through the hair and is converted to heat. With this method, the hair is destroyed and does not grow back.
