Today, Mike and Lisa investigate the most common concerns surrounding laser hair removal, as discussed in various online forums. They explore the concept of paradoxical hypertrichosis, synchronised hair growth, and the effects of laser treatments on hair colour, including the potential for hair to appear grey or lighter. KEY TAKEAWAYS There is a common misconception that laser hair removal can cause paradoxical hypertrichosis, where hair grows in areas that previously had none. However, many reports of increased hair growth after treatment are likely due to synchronised hair growth, which occurs when hair follicles are treated with insufficient energy, causing them to enter a synchronised growth phase. The effectiveness of laser hair removal is highly dependent on the fluence (energy level) used during treatment. Using a sub-lethal fluence can lead to ineffective results, where hair follicles survive and regrow, while using an appropriate fluence can effectively target and destroy the follicles. Some clients worry that laser treatments can cause their hair to turn grey or white. This is often attributed to the natural ageing process rather than the laser itself, as lasers target melanin in hair. If melanin is disrupted, it may lead to temporary changes in hair colour, but new hair growth should return to its original colour. Scarring can occur if the laser treatment is too aggressive, using excessive fluence without adequate cooling. Ice burns can also happen if ice packs are applied directly from the freezer without allowing them to thaw slightly. Proper cooling techniques are essential to prevent damage to the skin. Both conditions can arise from laser treatments. Hyperpigmentation occurs when melanocytes are stimulated to produce excess melanin, while hypopigmentation happens when these cells are destroyed. Individual factors such as skin type, medication, and sun exposure can influence these risks, making it crucial for clients to discuss their concerns with trained professionals. BEST MOMENTS "Paradoxical hypertrichosis occurs when some of these follicles come into action and start growing hairs in places that they previously didn't." "I get a lot of people saying, um, well, they, they, they won't start laser because they're worried that it'll just grow back thicker. But I'm like, if that happens, they're doing it wrong." "If you remove the follicle, it will work, of course, because then it doesn't matter what the hormones are doing." "Maybe you just got grey hair. I don't know. Maybe it just came in and it's grey and the laser will not be absorbed into the grey hair." "The biggest risk is poor training, which will lead inevitably to poor results." ABOUT THE HOSTS Mike began his career in medical lasers in 1986 with a physics degree and a post-grad in bioengineering. He helped develop the scar-free removal of tattoos using a Q-Switched Ruby Laser in Glasgow, and the world's first IPL system. Known well in the industry for his hard truths, no BS attitude and logical answers. As the author of three books, articles for medical journals, a well read blog, a Laser Protection Advisor and contributor to the BMLA, Mike is the Laser Guru. Lisa's claim to laser fame is being Mike's daughter. Growing up with lasers and never avoiding a physics lesson from her Dad, it was natural to enter the industry. Leaving a corporate career with a baby to jump into self employed life came with challenges. Despite that Lisa has been well recognised for her teaching style, practical tips, bringing the compassion to the science, and laser mentoring.
