In this episode, Lisa and Mike, dive into the common frustrations surrounding laser hair removal and why results can vary so significantly between individuals. Joined by Lisa’s newborn, Baby Bryan (Rosha), they discuss how subpar training and a lack of fundamental biological understanding within the industry contribute to inconsistent outcomes.

KEY TAKEAWAYS

Many laser technicians are taught to ‘under-treat’ or follow rigid, incorrect protocols, leading to more sessions with fewer results.

Energy output on a screen may not match what is actually being delivered; machines naturally lose efficiency over time and require regular professional calibration.

Different body areas have different growth cycles (e.g., leg hair has a very long anagen phase), meaning treating every area at the same four-week interval is often ineffective.

Thicker hairs tend to be deeper in the skin. Effective treatment requires enough energy (fluence) to reach the follicle's base, which varies by body site.

Firing multiple low-energy shots (e.g., three shots at 10 Joules) does not equal the depth penetration of one high-energy shot (e.g., one shot at 30 Joules).

BEST MOMENTS

"You pass your test, and then you're free to drive on the roads, and that's when you learn to drive properly. It’s the same in the laser game."

"A lot of people out there, they don't know what they don't know."

"Calibration is really only valid for that day. All machines, they all lose efficiency over time."

"If you're targeting hair with a 'sub-lethal threshold', you will not kill the follicles. They will regenerate, they'll grow back, and the hairs will be finer."

"The higher the fluence, the deeper it goes. It's as simple as that. And the deeper you can penetrate into the skin, the more follicles you'll hit."

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.
