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.

In today's episode, Mike and Lisa look at the complexities of safely and effectively treating deeper skin tones, particularly those with higher melanin concentrations. They discuss the importance of understanding how melanin affects laser treatments, noting that darker skin absorbs more energy, which can lead to increased risks of cellular damage and pain. Both Mike and Lisa challenge common misconceptions about using lower fluences for darker skin, advocating instead for higher fluences combined with enhanced cooling techniques to achieve optimal results.

KEY TAKEAWAYS

• Darker skin has a higher concentration of melanin throughout the epidermis, which absorbs more light energy from lasers, potentially leading to increased temperatures and a higher risk of cellular damage.

• Contrary to common training advice, using lower fluence and longer pulse widths on darker skin can be counterproductive. Lowering fluence reduces the total energy available for treatment, making it less effective.

• The ND:YAG laser at 1064 nanometers is preferred for treating darker skin tones because it is absorbed less by melanin, allowing more energy to reach the dermis where treatment is needed.

• Increased cooling time is essential when treating darker skin to mitigate the higher temperatures generated by increased melanin absorption. Recommended cooling times may be longer for darker skin compared to lighter skin.

• Practitioners should exercise caution when treating darker skin tones, especially if they are inexperienced. It is advisable to gain more experience before attempting treatments on darker skin to ensure safety and effectiveness.

BEST MOMENTS

"Darker skin has more melanin than lighter skin. In lighter skin tones, we tend to find most of the melanin resides in the basal layer."

"Lowering the fluence is a bad idea. That's just never going to work. You'll end up doing many, many more treatments and you might never get a good result."

"If you're going to use high fluences, then you must use much more cooling to compensate before and after the treatments."

"The melanin is a barrier, yes, essentially, and it steals energy."

"As the skin tone gets darker, you just got to be much more careful. That's basically it in a nutshell."

In this episode, Mike and Lisa delve into a concerning trend in the laser and IPL industry: the potential capping of fluence output by machine manufacturers. They discuss recent experiences shared by practitioners who found their machines unable to deliver the higher fluences promised in their manuals, raising questions about the implications for treatment efficacy. Mike and Lisa advocate for the need to empower users with the ability to access the full potential of their devices, rather than imposing arbitrary limits that could hinder results.

KEY TAKEAWAYS

• There is a growing concern in the industry regarding laser suppliers potentially capping the fluence output of their machines, which may limit practitioners' ability to achieve optimal results.

• Limiting the fluence can significantly affect treatment outcomes, particularly in procedures like hair removal and vascular treatments, where higher fluences are often necessary for effective results.

• The practice of capping machine outputs suggests a lack of trust in practitioners' abilities and highlights the need for better training. Proper training should empower users to operate machines at their full potential safely.

• The analogy of buying a car that is limited to a certain speed illustrates the frustration practitioners may feel when they are sold equipment that cannot perform to its advertised specifications.

• Effective cooling techniques are crucial when using higher fluences. Practitioners should be trained to understand the balance between delivering effective energy and ensuring patient safety through proper cooling methods.

BEST MOMENTS

"Are laser suppliers capping the amount of fluence that their machines are putting out for their clients or the practitioners?"

"It's kind of like the manufacturer saying, well, we don't trust you to use the machine to its full capacity."

"If you're being limited in what you can deliver to the skin, then that will limit your results, no doubt about it."

"If the company is selling you a machine and they are either capping or limiting it, then the company is not providing you with the proper service."

"It shows a lack of trust in your customers, and it also shows, to me, a lack of proper training."
