Blog – How does laser hair removal work?
In the quest for smooth, hair-free skin, many of us have tried various methods, from waxing to shaving and everything in between. These methods can be time-consuming, painful, and often lead to regrowth within a matter of days or weeks. Fortunately, modern technology has provided us with a more effective and long-lasting solution: laser hair removal. In our first blog post, we will unravel the science behind laser hair removal and explain how it works its magic…
The Basics of Laser Hair Removal
Laser hair removal is a medical procedure that uses concentrated beams of light, or lasers, to remove unwanted hair. The principle behind this technology is simple yet highly effective: selectively targeting hair follicles to inhibit their ability to grow new hair.
Here’s a step-by-step breakdown of how the process works:
1. Selective Photothermolysis: Laser hair removal relies on a concept known as selective photothermolysis. This involves matching a specific wavelength of light with the target (melanin) in the hair follicles. Melanin is the pigment responsible for the colour of our hair and skin. The Candela Gentlemax Pro Plus laser emits a light beam that is absorbed by the melanin in the hair follicles while sparing the surrounding skin. To demonstrate this, we undertook a little science experiment here at The Laser Lounge showing how the Candela laser targets only the melanin pigment…
2. Targeting the Hair Follicles: The melanin in the hair follicles absorbs the laser’s energy, which is then converted into heat. This heat damages the hair follicles’ ability to grow new hair.
3. Hair Growth Phases: Hair grows in cycles, and laser hair removal is most effective during the anagen phase, when the hair is actively growing. Only a proportion of the hair follicles are in the anagen phase at any time, and hence why we treat with multiple sessions over an approximate 8 month period.
4. Cooling Systems: The Candela Gentlemax Pro Plus uses a unique and patented DCD cooling system. This DCD system sprays a short pulse of liquid cryogen both before and after the laser to ensure your comfort and protect your skin.
5. Gradual Hair Reduction: Following a laser hair removal session, you may notice some hair shedding. However, it typically takes several sessions spaced a few weeks apart to achieve the desired results. Over time, as the hair follicles are repeatedly exposed to the laser, hair growth becomes finer and less noticeable.
Now that we understand the science behind laser hair removal, let’s explore some of the key advantages of this popular cosmetic procedure:
1. Precision: Laser hair removal selectively targets the hair follicles, leaving the surrounding skin undamaged.
2. Long-Lasting Results: Unlike temporary methods like shaving or waxing, laser hair removal offers long-lasting results. Many people experience permanent hair reduction after completing their recommended sessions.
3. Speed and Efficiency: Laser hair removal can treat multiple hair follicles simultaneously, making it a quicker option compared to traditional hair removal methods.
4. Reduced Ingrown Hairs: Since laser hair removal inhibits hair growth, it significantly reduces the occurrence of painful ingrown hairs.
5. Minimal Discomfort: The discomfort associated with laser hair removal is usually mild and temporary. The cooling system in the Candela Gentlemax Pro Plus help make the procedure more tolerable.
Conclusion
Laser hair removal is a highly effective and popular method for achieving smoother, hair-free skin. By harnessing the power of selective photothermolysis, this technology targets hair follicles at their root, gradually reducing hair growth. While it may require multiple sessions, the long-lasting results make it a worthwhile investment for those seeking a permanent solution to unwanted hair.
