Laser Permanent Hair Removal

Permanent Laser Hair RemovalLaser permanent hair removal is a relatively recent advancement in hair removing techniques. It is an expensive method and is claimed by some to be just as effective as most other methods. Expense aside, people are ready to go to any extent to attain a beautiful body and face.


In the mid-1990s, after many experiments for almost twenty years, the first epilation performed by laser was commercially available in the market. Laser is a kind of light, which is also called 'phototricholysis' or 'photoepilation'.

There are numerous types of epilators - one such epilator uses a xenon flash lamp. The xenon flash lamp emits intense pulse light (IPL). Treatment through the epilators using IPL is also known as hair removal by laser but the laser is not actually been used in this case. Hence, xenon flash lamp should not be mixed with laser hair removal.


"Selective photothermolysis" is the basic principle behind laser permanent hair removal. The hand held device is pressed against the area of which hair to be removed and laser light of a single color and wavelength is emitted. This high energy light is absorbed by the targeted melanin pigment present in hair shaft, which results in producing heat in the hair. This heat is transmitted to the hair follicle which gets inflamed, and the follicle goes into talogen phase (resting).

Darker pigments absorb laser lights, so this method works best when the hair to be removed is dark and the skin around it is as pale as possible.

There are three types of specific wavelengths used in this type of treatment depending on the type of skin.

  1. Alexandrite: 755nm (most effective, but only safe on light skin)
  2. Pulsed diode array: 810nm (for light to medium type skin)
  3. Nd: YAG: 1064nm (for darker skin)

It is not possible to remove red-pigmented hair using this method due to the selective absorption by pigments.

Gels, sprays and air are used for cooling the skin in order to reduce irritation during the treatments.

Points to be kept in mind while using laser treatments:

  • Areas near the eyes: One has to be very careful while using a laser in areas near the eyes because it can be harmful for the eyes if flashed directly into them. Use of protective eyewear is recommended while using any kind of laser.
  • Areas inside the nasal cavity or ears: Area inside the nasal cavity should be avoided even if one has more hair growth inside the nose and inside the ears. It is not recommended at all to use in such sensitive areas.
  • Area near or around the genitals: It can used in areas near the pubic region as well as on the reproductive organs of both sexes but is somewhat painful and has to be used with utmost care. A topical desensitizing spray is recommended while using in such private areas.
  • Area near the areola: It has been considered safe and recommended for use in areas near the areola of both sexes.
  • Number of sessions: The number of sessions depends on various parameters, which can be decided only by a suitable medical practitioner. These different parameters are the area of the body being treated; the skin color, thickness of hair, gender of the concerned person. These are vital points to be considered in deciding the important factor of how many sessions are required for each area.
