Types of lasers for hair removal

Let’s check the laser machine for permanent hair removal.

  • Diode: This laser is directly concentrated into the hair follicles and the melanin contained in them. The pigment then absorbs the concentrated beam and is destroyed which restricts future hair growth. The diode has a wavelength of 810 nm & it is suitable for all types of skin. This technique does not damage the skin but can cause slight redness.
  • Nd-Yag: Nd-Yag Laser has a wavelength of 1064 nm & it is suitable for mostly dark color. This laser is mostly used for tattoo removal and hyperpigmentation, but can also be used for hair removal. A lotion made out of carbon is applied on the skin which then absorbs the laser wavelength and penetrates the hair follicles. This method is slightly discomforting.
  • Alexandrite: Alexandrite is a laser which works in wavelength of 755 nm. It is considered to be the fastest laser for hair removal; however, it can also cause more discomfort to the patient. A large surface area can be covered in the very little amount of time by using this technique. It works best with the olive-colored skin tone.
  • Intense pulsed light (IPL): IPL is not considered as laser, and works with a wavelength of 650 nm & it is suitable for pale to medium skin. This technique uses the IPL laser which is comparatively less intense than its counterparts. It is mostly used for removal of facial hair, bikini line and pubic areas. As the beam is not very concentrated it does not damage the skin.

How does laser hair removal work?

It attacks the hair follicles with a lot of concentrated energy, which consequently destroys them. However, hair follicle reacts in two ways:

  • They will absorb all the light & the hair follicle will die.
  • After absorbing the light the hair follicle size will be reduced.

A laser beam will be aimed at the hair follicles on the treatment area and therefore hair follicle pigments will absorb the laser energy. Then with the number of sessions, they reduce in size & hence they are no longer able to grow. Individuals with a dark complexion and the ones who have thick hair respond very well to treatment as compared to the ones with a fair complexion and thinned out hair.
