Laser hair removal works by emitting a concentrated beam of light that is absorbed by the pigment (melanin) in the hair. The light is converted into heat, which damages the hair follicle and prevents future hair growth. The treatment primarily targets hair in the active growth phase, so multiple sessions are needed to effectively treat all hair types across different growth cycles. The laser is precise and only affects the hair follicle, leaving surrounding skin unharmed.

The sensation during laser hair removal varies depending on the treatment area and individual pain tolerance. Most people describe the feeling as a quick, mild pinch or a rubber band snap against the skin. While it's generally well-tolerated, some areas of the body, like the bikini line or underarms, may be more sensitive. Numbing creams or cooling devices are often used to enhance comfort during treatment. For most clients, any discomfort is temporary and fades shortly after the session.

Typically, 6–8 sessions are recommended for optimal results. This is because hair grows in different phases (growth, rest, and shedding), and laser hair removal is most effective on hair in the active growth phase. Sessions are spaced 4–6 weeks apart to allow the hair to cycle into the growth phase. After completing the initial treatment plan, most clients experience a significant reduction in hair growth, but some may need occasional touch-ups to maintain smooth, hair-free skin.

Laser hair removal provides long-lasting results by significantly reducing hair growth, but it is not always permanent for everyone. Many clients experience permanent hair reduction, with some regrowth occurring over time. Any regrowth tends to be finer and lighter in color, making it less noticeable. For some individuals, maintenance treatments may be required every 6–12 months to keep the area hair-free. Results can vary depending on factors such as hair color, skin type, and the area being treated.
