How Does Laser Work In The Scalp

What really happens when light in the form of a laser beam is hitting the scalp

? How far does it penetrate and what good does it do? There are as many questions as there are people and below I will go into one big consequence for it all to work photoreceptors. In order for the laser light to be absorbed, there must be receptors to catch the light. Such receptors are well known in plants, but are there human light receptors other than those in the eyes and in the skin?

We may have to step back in time in order to begin to understand the mechanisms involved. That low energy light particles can produce significant, and at times, life-supporting changes in various organisms, is not at all new. Our primordial ancestor, the purple bacteria, provides a vivid example. Found in abstemious habitats below that of plant life - e.g. the bottom of ponds and topsoil, depending on the species - the purple bacteria inevitably lives on a meagre amount of light. Only the reminder of light unharvested by plants penetrates to those depths. But with the carotenoids in its light-harvesting complexes absorbing light at 500 nm wavelength, and its bacteriochlorophyll absorbing at 800-850 nm, this life form is able to carry out complex life-supporting metabolic processes with relatively minimal light energy.

To date, more than three hundred photochemically reactive proteins, capable of harvesting low light energy, have been identified in both prokaryotic and eukaryotic organisms. Many more are being discovered yearly. In humans, the most commonly known photochemically active receptor proteins are rod and cone pigments in the eye. However, other human photoreceptors have been discovered in recent times. Given the discovery of photoreceptor proteins in the pineal gland, the hypothalamus, and other tissues of lower vertebrates, it is only a matter of time that it will become clear that other human tissues have photo reactive proteins as well.

Photo biological mechanisms will be spoken about briefly and how successful laser treatment can be. Laser therapy is not working through heat as IPL does but through biostimulation in cells. What happens when this relatively weak laser light encounters our cells? First, quite a number of things happens locally, where the laser light hits effect. As mentioned above, it has been observed that if laser administered in the right dose, certain cell functions are stimulated, is particularly evident if the cell in question has an impaired function.
