Understanding Laser Treatment
A laser produces beam of highly concentrated light. The light emitted by the Long Nd:YAG Laser is absorbed by the pigment located in hair follicles. The laser pulses for a fraction of a second, just long enough to vaporize the pig-ment, disabling several follicles at a time to elimi-nate or significantly impede the hair re-growth.
How does hair growth effect Laser Hair Removal treatments?
Every hair goes through 3 cycles of growth. The hair you can see is either in its active anagen growth cycle (still attached to the hair follicle) or in its inactive cataqen phase (already separated from the follicle). Inactive hair will fall out on its own as it has completed its growth cycle and already disengaged from the follicle. Beneath the surface of the skin are the dormant hair follicles that have not entered a growth cycle. The laser targets the hair you can see, meaning it will remove both the active and inactive hairs. Hair in an active growth cycle will not grow back as the laser will destroy the hair follicle beneath the skin. Inactive hair will be removed; however, it will grow back as the follicle is still intact. As the hair moves through its cycles, repeated sessions are necessary to treat the follicles when they enter the growth phase.
How many sessions do I need?
The number of session depends on various parameters, including the area of the body treated, skin color, coarseness of hair, and gender. since hair grows in several phases, and laser can only affect the currently actively growing follicles, several sessions are needed to kill hair in all phases of growth.
In general, it is necessary to foresee between 3 - 8 treatment sessions. Coarse dark hair on light skin is easiest to treat. Finer hair and hair on darker skin is harder to treat and may require more treat-ments. Certain areas (notably men's and women's faces) may require considerably more treatments to achieve desired results.
What is the interval between each session?
Usually, treatments are spaced 3-12 weeks apart to start, although the spacing depends upon indi-vidual’s response to treatment. Instead of following an arbitrary schedule, you should wait until you have experienced shedding of the treated hairs, which should complete in less than a month, and see enough hair come in after the hair-free period to have another treatment. Treatment spacing also depends on area treated as hair cycles vary based on the body part.
What to expect during the laser hair removal procedure?
During the procedure, laser light will be delivered through a hand held piece attached to a laser console. Laser treatment itself may cause a slight tingling sensa-tion. Most patients tolerate the procedure well. But because some areas of the body are more sensitive than others, topical anesthesia can be an option. The appearance of the treated area immediately after the laser session will vary from patient to patient depending on the extent of treatment and skin type. Immediate after-effects, if any, redness will be visible which disappears in a short time. Most people return to normal activity right away.
Can the dark skinned people or light haired areas be also a candidate for laser hair removal procedure?
A unique advantage of the CoolGlide Laser is the ability to deliver very high power. It can then eliminate resis-tant individual hairs, including those fine, light brown hairs which cannot be treated with other lasers. It also treats all skin types (I-VI) including tanned skin in the summer.
