1.New laser hair restoration comb adopts the latest soft laser technology (650nm) with Micro-current and high power LED light therapy. It generates 650nm low level laser energy which stimulates hair follicle, activate the atrophic scalp cells, balance bio-energy and improve metabolism. Micro-current energy is a low-frequency electric pulse. It effectively activates cells and accelerate generation of hair follicle.2.Laser wavelength is 890nm which promotes the detachment of dead cells and regeneration of new cells. with the three powerful technologies, the hair-growth nutrition absorption is greatly improved. Meanwhile, massage scalp accelerate the blood circulation of capillary vessel and enhance permeability of cells to supply the nutrition to the musculature and skin more effectively. With the laser energy, the increase in blood flow brings the important nutrients into the follicle, the regeneration of hair follicle is achieve, which will produce healthier hair, prevent further hair loss, and stimulate hair growth.3.EMS Electroporation& RF (Radio Frequency)4.A. Activate collagen recombination and hair growth, through the specific EMS electric current can stimulate muscle movement, so that to improve fine lines and wrinkles, and will not cause any damage to skin.5.B. The characteristics of high frequency is flowing in the shortest distance between the electrode, according to the specialty of high frequency and resistance of biological tissue, it will produce energy in the easy flowing parts, it means will produce heat.Specifications:1.
