How laser hair removal?
Laser Hair removal is the use of laser energy to produce long-term reduction of hair. This is accomplished by the production of heat in the hair, which is transferred to the hair follicle, which in turn produces inflammation, inflammation and this sends a signal to the hair follicle to go in the rest (telogen) phase .
What is a laser, really?
First, what is a laser? A laser is a device that produces light of a single color or wavelength. In dermatology, lasers produce light pulses of high energy which is absorbed by the desired target. In the case of hair removal, the target is melanin pigment in the hair shaft.
A delicate balance
The trick, laser hair removal seeks the hair shaft without damaging the melanin pigment in the skin surface. Thus, the laser light must be time to heat the hair, but not too long, to allow the heat to spread to the surrounding skin causing damage. In addition, the darker skin of a patient, the harder it is to avoid hurting the skin surface while treating their hair. For this reason, there are three main types of laser hair removal that are used today, and depending on the thickness of hair and skin color, a laser can provide advantages over the other.
When performing laser hair removal, experience matters
In addition to lasers, light sources intense pulsed are also used for hair removal. These light sources do not emit a single color or wavelength of light, but emit light with many colors. It may be more difficult to predict the outcome and avoid complications when using light sources containing many wavelengths of light. However, the results of any device depend on the experience of the practitioner.
How many treatments?
Normally, a series of three to five treatments are administered four to eight weeks apart, depending on the location of the hair. Following the first round of treatment, after treatment is administered, and more generally with longer intervals. Some number of maintenance treatment may be needed to keep away all the hair in a given area. After a single treatment, hair in a given area is generally reduced in quantity and thickness for a very long time. However, it is perhaps not completely disappeared. To keep an area completely devoid of hair, maintenance treatments are still needed. These treatments maintenance might be necessary for the sole years or more. It depends on the area being treated as well as the individual. As with any other traits of an individual, the frequency of maintenance treatment varies considerably from one person to another.
