The Science of Laser Hair Removal
The Science of Laser Hair Removal
Laser hair removal is the use of laser energy to produce long-term hair reduction. The heat from the light of the laser is absorbed by the pigment, or melanin, in the hair. That heat then triggers inflammation in the hair follicle, which causes the follicle to go into its resting (telogen) phase. While resting, the follicle produces no hair.
A Series of Treatments Needed?
|Laser hair removal is accomplished in a series of sessions generally done monthly or every other month. The average number of sessions to achieve over 80 percent permanent hair reduction in 80-90 percent of good candidates is approximately 4 to 6 sessions. Good rule of thumb to follow is on average, people need a minimum of 3 treatments for optimal results. Most people do not require more than six treatments, although people with hormonal imbalances or people who normally wax or pluck a lot may require more sessions.|
|In between these monthly sessions some of the hair will regrow. Hairs that may have been dormant during your previous laser hair removal session may now be in the growth phase. This is where the need for multiple treatment sessions arises. Multiple sessions ensures that all the hairs are subjected to the treatment. These hairs may be shaved by the patient between sessions if desired.|
Comfort Varies Among Individuals
The discomfort associated with laser hair removal varies considerably among individuals. How much discomfort you’ll feel will depend not only on such factors as your skin type, the thickness and density of your hair, and the area of your body being treated, but also on your ability to tolerate or feel pain. Although it rarely occurs, a small number of patients find that they are unable to undergo laser hair removal treatments due to their low threshhold for pain.
Because laser light produces heat, you’ll feel some kind of sensation during your hair removal treatment. In addition, hair follicles are surrounded by nerve endings, which may react to the heat by creating a sensation of discomfort or even mild pain. Patients often compare the sensation to having a rubber band snapped against their skin. Certain areas of the body hurt more than others during laser hair removal. In addition, patients with very thick, dark hair may experience more discomfort than those with thin or light-colored hair. This is because thicker, darker hair absorbs more of the laser light during treatment. Generally, the hair becomes thinner and less dense after each subsequent treatment. That’s why the most discomfort is usually experienced during the first treatment. In some situations, a numbing cream can be used to minimize the discomfort.
Risk is Rather Small
Any laser procedure can cause scarring, and this is included as a risk on most consent forms you will sign prior to laser treatment. However, the risk of scarring from laser hair removal is rather small and is a function of many things including:
