What kind of lasers are used for laser hair removal? Do the lasers cause damage to the skin under the hair?
There are literally hundreds of brands of lasers for hair removal, but only a few types. The most common types of lasers for hair removal are Diode, Alexandrite or Yag. The Alexandrite and Diode lasers are generally for skin types I - IV (Caucasian to East Indian) and Yag is for African American and African skin types (V and VI).
Although there are slight differences between the brands (speed, type of cooling, etc.) generally the key factors in your result will be the type of laser and the quality of the service (experience and skill of the practitioner). Find an office with multiple wavelengths (Diode, Yag, Alexandrite) and with experienced professionals and you should do fine.

The types of lasers most often used for laser hair removal are "Diode",
"Alexandrite" and "Nd:Yg" (Yag). These do not represent the brand of
laser - Lightsheer, Sciton or Cynosure - but rather the type of light
being used in the device. The damage caused by laser hair removal is to
the small blood vessel that feeds the hair. By heating the hair, we can
close the small blood vessel that supplies the hair with blood, thereby
causing permanent removal of the hair. This damage is by design and
does not affect anything except the hair and the blood vessel.
