Working theory :

Hair growth comb 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. High power LED light consists of light wavelength which promotes the detachment of dead cells and regeneration of new cells. The hair-growth nutrition absorption is greatly improved. Meanwhile, constant massage and pat of 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, while taking away harmful waste products such as DHT. The increase in ATP increases cellular metabolism and cellular activity. As a result, the regeneration of hair follicle is achieve, which will produce healthier hair, prevent further hair loss, and stimulate hair growth.
