Laser hair: side effect seen treatment for baldness
Roughly 10 years ago, when the first laser equipment for the ultimate disposal of hairs, seen a great revolution in this area. Those unwanted hair were eliminated, providing a much improved aesthetic appearance, as in the annoying people from having to shave often.
Like everything there are flowers, rare side effects occur such as burns and residual stains, but one of them caught the attention of researchers in this area: an increase in the number of hairs in the region around the treated area. This side effect does not initially understood, it may be today, the solution for thousands of people suffering from hair loss.
Biostimulation: treatment of hair loss
The name for this phenomenon is called biostimulation, ie the energy generated by laser to destroy the hair arrives at low power in neighboring tissues in the treated area. It is believed that this low power when it reaches the bulge, a structure situated on the hair shaft, very rich in stem cells, cause a stimulation of these cells by providing a thickening of pre-existing hair.
From this fact, entering the market, low-power lasers with wavelength sufficient to reach this region of the hair in order to address various aspects of hair loss. It should be introduced when the drop is still in the initial phase at the time of miniaturization of the hair, as this technique does not return the hair that fell long as the hair follicles at this stage have already been destroyed.
The best indications are: people who have a family history of baldness or thinning hair, you started to notice an increase in the fall, people with hair loss for some reason of illness or stress, those who have noticed a thinning or a change in the structure the hair.
Darkening of gray hair?
These devices also have the potential to be used to darken the hair, by the same stimulus in stem cells, which will stimulate the melanocytes to produce melanin, the pigment that will give color to hair, but in practice this effect is not yet well established.
The evolution of technology opens up an avenue for the treatment of baldness. More studies need to be done, but at the moment the results to strengthen hair and to recover the lost hair recently are very promising.
