Laser hair removal works by targeting and destroying the hair follicles, which are responsible for hair growth. The procedure uses a concentrated beam of light, known as a laser, to selectively heat and damage the hair follicles without harming the surrounding skin.
Here's a step-by-step explanation of how laser hair removal works:
1. Preparation: Before the procedure, the area being treated is cleaned and trimmed to 1 cm in length. It's important to trim the area to ensure that the laser energy is focused on the hair follicles rather than the surface of the skin.
2. Targeting the hair follicles: The handheld laser device is then used to deliver the laser energy to the targeted area. The laser emits a specific wavelength of light that is absorbed by the pigment (melanin) in the hair follicles. The darker the hair, the more efficiently it absorbs the laser energy.
3. Absorption of laser energy: As the laser energy is absorbed by the hair follicles, it is converted into heat. This heat damages the follicles, inhibiting their ability to produce new hair.
4. Cooling the skin: To protect the surrounding skin from excessive heat, many laser devices have a cooling mechanism built into them. This helps to minimize discomfort and reduce the risk of skin damage. Using gel ice packs can add extra protection for the skin and discomfort.
5. Repeat treatments: Hair grows in cycles, and not all hair follicles are active at the same time. Therefore, multiple laser hair removal sessions are typically needed to target hair follicles in different growth phases. The number of sessions required varies depending on factors such as the area being treated, hair thickness, and individual response to treatment.
6. Gradual reduction in hair growth: Over time and with repeated treatments, laser hair removal can result in a significant reduction in hair growth. Some individuals may experience permanent hair loss, while others may require occasional touch-up sessions to maintain the results.
It's important to note that laser hair removal is most effective on individuals with dark hair and light skin, as the contrast between the hair and skin color allows the laser to more accurately target the hair follicles. Consulting with a qualified professional is essential to determine if you are a suitable candidate for laser hair removal and to discuss any potential risks or complications.
