Why do we space out treatment times for laser hair removal

WHY DO WE SPACE OUT TREATMENT TIMES FOR HAIR REMOVAL.

Laser hair removal works by selectively targeting the melanin (pigment) in the hair follicles with laser light energy. The high energy of the laser is absorbed by the melanin, which damages the hair follicle and impairs its ability to produce new hair. However, not all hair follicles are in the same stage of growth at the same time, and only those in the active growth phase (anagen) can be effectively treated.

Hair follicles go through three stages of growth: anagen (active growth), catagen (transitional), and telogen (resting). On average, about 10-15% of hair follicles are in the resting stage at any given time, and these cannot be treated with laser hair removal. Additionally, the duration of the anagen phase varies between individuals, and can be influenced by factors such as hormones, age, and overall health.

Therefore, multiple laser hair removal treatments are typically needed to target all the active hair follicles in a given area. The treatments are spaced apart by several weeks or months to allow for new hair growth and to target follicles that were in the resting phase during previous sessions. By doing this, laser hair removal can achieve more effective and permanent results, as each successive treatment further damages the hair follicles, making it more difficult for them to produce new hair.

The energy used for laser hair removal may be adjusted for each treatment session, depending on the individual’s skin and hair type, as well as the desired results. In general, the energy used during a laser hair removal treatment is based on a balance between effectively damaging the hair follicles and avoiding harm to the surrounding skin.

In some cases, the energy may be increased gradually over the course of several treatments to improve the effectiveness of the laser hair removal. This approach is called “progressive energy delivery.” By gradually increasing the energy, the risk of side effects, such as skin irritation or pigmentation changes, can be minimised. However, this approach should only be performed by trained and experienced professionals, as improper use of laser energy can result in harm to the skin.

In other cases, the energy used for each treatment may remain the same or be reduced, based on the individual’s response to the treatment and the desired results. The optimal approach for any given individual will depend on a variety of factors, including the individual’s skin and hair type, the area being treated, and the desired outcome. An experienced provider will be able to determine the best energy level for each individual and make adjustments as necessary.

The energy level of the laser used for laser hair removal needs to be correct for the individual, in order to effectively target the hair follicles and reduce the risk of side effects. The correct energy level will depend on a variety of factors, including the individual’s skin and hair type, the area being treated, and the type of laser being used.

If the energy level is too low, the laser may not be effective in damaging the hair follicles, and multiple treatments may be needed to achieve the desired results. On the other hand, if the energy level is too high, there may be an increased risk of skin irritation, pigmentation changes, and other side effects.
