Choosing the right hair loss solution can be overwhelming, and understanding the technology behind the devices is crucial. In this final question of our interview series, trichologist Iain sheds light on the key differences between the lasers used in HairMax devices and the LEDs used by many competitors.

Power and Focus: The Advantages of Laser Diodes

Iain explains that the primary difference lies in two key aspects:

• Power: HairMax devices utilise laser diodes, which offer a more concentrated and powerful light beam compared to LEDs.
  
  
• Directionality: Laser diodes emit light in a narrow, focused beam, ensuring it reaches the targeted areas of the scalp. LEDs, on the other hand, disperse light in all directions, leading to potential energy loss.
  
  

Precision Makes a Difference: Penetrating Deeper Layers

The focused nature of laser light allows it to penetrate deeper into the scalp, reaching the hair follicles located within the dermis. LEDs, with their scattered light, might not reach these follicles as effectively.

LEDs: A Supporting Role

Iain acknowledges that LEDs aren't entirely without benefits. Studies have shown that LEDs used in placebo devices during some LLLT research did stimulate some hair growth, albeit to a lesser extent than laser diodes.

Science-Backed Choice: HairMax and Laser Technology

Iain emphasises the importance of scientific backing when choosing a hair loss treatment. HairMax devices, with their laser diode technology, are supported by a larger body of research compared to LED-based competitors.

The Takeaway: Power and Focus for Targeted Results

Laser diodes, like those used in HairMax devices, offer a more powerful and focused approach to LLLT. This potentially leads to deeper scalp penetration and more targeted hair follicle stimulation compared to LED-based devices.
