Hair Removal in Chiangmai

Laser hair removal is a long-lasting form of hair removal that damages or destroys the hair follicle.

However, the hair may regrow, particularly if the follicle is damaged and not destroyed during the laser hair removal procedure.

For this reason, many doctors now refer to laser hair removal as long-term hair removal rather than permanent hair removal.

Read on to learn about how laser hair removal works, how long it lasts, and the costs of laser hair removal procedures.

Laser hair removal uses light to target the pigment in individual hairs. The light travels down the shaft of the hair and into the hair follicle.

The heat from the laser light destroys the hair follicle, and a hair can no longer grow from it.

Hair follows a unique growth cycle that involves resting, shedding, and growing periods. Recently removed hair that is in a resting phase will not be visible to the technician or laser, so a person may need to wait until it regrows before removing it.

For most people, laser hair removal requires several treatments over the course of 2 to 3 months.

Side effects and risks

During treatment, some people experience burning, stinging, or discomfort. For this reason, many technicians apply a numbing cream to the area they are treating. However, some people may have an allergic reaction or skin irritation in response to the numbing cream.

Minor side effects are common, and may include:

changes in the color of the skin, particularly in people with dark skin, which are usually temporary
skin redness
blistering or crusting of the skin

Sometimes, irritation related to hair removal can cause scarring. Damaged skin can also become infected. Though rare, skin infections can spread and become life-threatening.

Providing a detailed medical history and discussing risks and benefits can help the provider determine the right treatment, reducing the risk of serious side effects.

Following hair removal, a person should avoid sun exposure. The sun can irritate the skin, which increases the risk of blisters and scars.

People who experience intense pain, a fever, crusting, blisters, or other signs of skin damage or infection should seek medical attention.
