Laser Hair Removal
Laser hair removal is effective in people with lighter complexions and darker hair.

Although laser hair removal may keep unwanted hair away for months or even years, it does not ensure permanent hair removal.

Laser hair removal is a procedure in which unwanted hair is removed using a laser. The laser destroys the hair follicles and prevents hair growth. It is considered the best treatment for unwanted hair removal, but laser hair removal is not permanent.

The destroyed hair follicles inhibit hair growth for longer periods; however, the hair regrows after certain periods. The hair that grows after the laser treatment is usually finer and lighter in color.

Important things to know about laser hair removal

  • Stay away from the sun
  • Painless procedure
  • Few and temporary side effects
  • Quick procedure
  • More than one session is often required

How does laser hair removal work?

During the hair removal procedure, the laser emits light, which is absorbed by the hair follicles. This light is converted to heat and destroys hair follicles in the skin from where the hair grows. This damage in the hair follicles may stop or delay hair growth. In most people, the hair grows back in a few months. Follow-up sessions of laser treatment may delay hair growth.

Common areas where laser hair removal is frequently performed include:

  • Chest
  • Back
  • Shoulders
  • Neck
  • Bikini line
  • Legs

Facial hair removal should be avoided around the eyes to avoid eye injuries.

Usually, six to eight sessions of laser treatments are required for maximum hair removal. In these eight sessions, maximum hair follicles are damaged but not all. The follicles are damaged and shrunk in size, which results in finer and lighter color hair, and the growth occurs very slowly.

As mentioned, 100 percent of hair removal is not expected; 75 to 90 percent of hair removal is seen.

Results may vary from person to person depending on the following:

  • Area of the treatment (hair removal done on the face may require several sessions for satisfactory results)
  • Settings used during the procedure
  • The number of follow-up sessions taken
  • An individual-specific hair growth cycle

Studies have reported that laser hair removal is effective in people with lighter complexions and darker hair because the color contrast makes the light travel easily and destroys the follicles. However, in people with darker skin, more sessions are required.
