Ultra-vibration × ultra-high vibration ultrasonic waves gently and quickly penetrate drugs such as treatments. The finish and staying power of treatments and colors are determined by how deeply the drug penetrates. The ultra-osmotic technology, which is a combination of "ultrasound" and "UFV", makes the molecules of the drug finer, so that the effect is extracted gently and quickly. Because it is waterproof, it can also be used for daily bath time. 1 MHz that does not damage hair and is suitable for drug penetration (1 million vibrations per second) is output stably and uniformly. Ultra-osmosis technology with double wavelength vibration of ultrasonic waves and UFV finely refines the molecules of the drug. It promotes the penetration of treatments, colorants, perms, etc. The comb shape hits the hair in multiple ways, bringing out the effect of ultrasonic waves evenly. (1) Can be used wirelessly You can use it just by turning on the power. It can also be used by connecting it to a cord. (2) Waterproof function (IPX5) It can also be used in the bathroom, IPX5 waterproof level. * Do not immerse in water or wash with strong water. (3) Ultra-micro-vibration (UFV) processing Ultra and fine vibrations are processed into the main body, and penetration is promoted by double wavelength vibration.
