Yes, Dee Dee …
Of course the experts believe that the laser does it’s work by heat … thermal injury. We know what such an injury is, because electrologists do it all the time to follicles.
However, stimulating hair growth? Delaying hair growth for years? Altering the shedding cycle? None of these effects are from thermal damage only. If thermal damage (only) is causing these effects, I have yet to hear an idea about WHY this is happening.
Something is happening at the cellular level that is not yet understood. All of these oddities will be described in the future when more evidence is gathered. Laser is a massive experiment and let’s hope there are no deadly side-effects. Such effects take many years to ascertain.
Meanwhile, the guinea pigs keep showing up; God bless 'em!
