Answer: No. Capillus lasers are cool-to-the-touch, meaning your LLLT treatment will be comfortable.

The Capillus laser therapy caps are not LED lights, but laser diodes that promote hair growth in adults with androgenetic alopecia. Lasers at ~650 nm (the wavelength that has been proven to regrow hair) are in the visible red spectrum of light.

Coherent and Incoherent Light

The major difference between LED and laser light is that laser light is “coherent” and LED light is “incoherent.” This means that laser light photons are in parallel. The light waves have the same frequency and the same phase.

In contrast, LED light is what’s called “incoherent.” This means that the light photons and waves do not have the same frequency or the same phase. In other words, LED light spreads out and lots of energy gets wasted. LED light cannot be concentrated or pulsed like lasers can, so it’s impossible to focus the light on specific areas.

Similarly, since LED light cannot be focused like laser light, LED does not penetrate the skin to the extent that laser light does.
