Over the years, laser hair removal treatment has been accepted and has mushroomed because of a better understanding of its use. Laser hair removal treatment may be the best form of hair removal, but it is not for everyone. Contrary to common conception laser hair removal is not permanent.
During hair removal treatments, lasers operate by producing light at different wavelengths, output and pulse widths. The wavelength establishes the point that the laser falls on, such as melanin (a dark biological pigment), water or veins. Lasers used for hair removal are intended to burn structures that hold dark color pigment. Thus, laser hair removal treatments work better for people with a lighter skin and darker hair. Similar to electrolysis, hair follicles in the growth phase (anagen) are more easily damaged than those in the resting phase (talogen). It should be noted that at least 15% of the time, hair follicles are in the talogen phase. That makes permanent hair removal impossible, and treatments have to be repeated.
Laser treatments are performed by a trained technician or a nurse, and can last from a quarter of an hour to an hour and a half. It is a common occurrence for laser treatments to give an uneasy feeling to the patient. The discomfort is not an issue when small areas are being treated, but it does cause problems when larger areas are treated. There are ways to decrease the degree of discomfort. One is to use ice on the area prior to the laser session. Generally, laser hair removal treatments do not require pain medications or sedatives. The treatment is relatively easy, and it does not take much time to recuperate. Unlike waxing, you can shave prior to treatment. Sometimes, the skin may turn purple, and this condition could last for days. Also, some areas may temporarily form blisters.
