Lasers deliver collimated, coherent light. This simply means that the light is focused in a column and does not disperse as much over the treatment area. Lasers are monochromatic by definition, which means they emit light at one wavelength.
A light emitting diode (LED) is a semi-conductor device that emits incoherent narrow-spectrum light. Some LED devices are also monochromatic, such as DynaMax Freedom100TM.
Light from both lasers and LEDs disperse once the light contacts body tissue. The depth to which they penetrate has nothing to do with whether the light is lased, but rather has to do with the wavelength and energy density.
As you can see by the diagram above, the amount of depth and dispersion that Dynamax 45mW diodes generate should be a strong consideration when you purchase a light therapy treatment option for hair loss.
Light output from an LED possess all the attributes of a laser except coherence. Findings at the cellular level would imply that the property of coherence is largely unnecessary for the clinical effects of these devices. In summary, at a particular wavelength, light that is emitted out of a LED or a Laser will have similar clinical effects on body tissue. Effects can be further enhanced by increasing the surface area of treatment device, and by increasing the energy density.
Bottom Line is that our LED's possess the required wavelength to actually reach and stimulate the hair follicle. Other cheap lasers (running on AAA batteries) are more than likely a waste of money.
