Phototherapy Using a Laser Comb

In the medical world, the use of lasers has long claimed its novelty. Lasers have been in use for medical purposes for many years and its uses range from surgery using high-powered lasers to stimulation of tissue repair. A newer application of laser technology is the use of laser light for treatment of hereditary hair loss.

Laser light generated by low-powered lasers has recently come into use as a non-surgical hair restoration treatment for pattern hair loss. In fact, hand-held “comb”, “brush” or “cap” laser devices are marketed for use at home. Larger “hood” or “cap” devices are used in hair restoration clinics only.

The cold lasers used for treatment of androgenetic alopecia deliver what is called low-level laser therapy (LLLT). The LLLT lasers are considered cold lasers because their light is absorbed by target tissue but does not heat the target tissue as occurs with lasers used to cut and remodel tissues. A laser comb uses LLLT. It has been providing people with a legitimate solution to hair loss and hair thinning problems. Laser and light emitting diodes (LED) are the most frequently used light sources in hair restoration treatment.
