Laser Hair Removal (IPL)

Laser hair removal relies on emitting a beam of light that transforms into heat via a handheld device, which glides across the skin. The heat emitted then selectively absorbs pigment in the hair root, effectively destroying it and leading to permanent hair reduction so that the hair no longer grows in its four distinct phases: anagen (growth phase), catagen (transition phase), telogen (resting phase), and exogen (shedding phase). Light-based hair removal (both laser and IPL) destroys the hair follicle in the anagen (growing) phase, which is why several sessions are necessary. The hair follicles are not injured if they are in another growth phase during the treatment.

Different skin tones require varying laser settings to stunt the hair’s regular growth pattern, and a single laser may not be suitable for all skin tones. Darker skin types are more prone to burns due to the increased amount of melanin in darker skin and always require special attention and expertise from your provider. Darker skin tones are also susceptible to post-inflammatory hyperpigmentation (PIH) due to increased melanin, so always ensure your provider is well-versed in laser hair removal. It’s also essential to avoid sun exposure and tanning for four weeks before your hair removal treatment for all skin types. The sun and tanning increases melanin production and can make patients prone to burns or hyperpigmentation. Wearing high-quality sunscreen and avoiding long periods of direct sun exposure usually provide adequate protection.

In addition to potential challenges with skin tones, the color of the hair may also affect the results. White, gray, and light-colored hair pose challenges for effective hair removal as the laser may struggle to detect and effectively destroy the hair’s color. While laser hair removal is most effective on coarse, dense, and dark hair, recent advancements now allow for treating light and fine hair more effectively.

The device is applied to each area sequentially during the treatment session, varying from a few minutes to an hour, depending on the location. Approximately five to 10 days post-treatment, the hair will shed, indicating that the hair follicle has been destroyed. Hair regrowth gradually diminishes with subsequent treatments, resulting in permanent hair reduction. Most patients typically observe an initial decrease in hair growth following the first treatment. However, after completing an entire series of three to six treatments, most patients experience permanent hair loss of approximately 90% or more. Future touch-up treatments may be necessary to address any new hair growth that may develop.
