  • Aspen hair brush for preventing hair-loss
    Publication number: 20080040878
    Abstract: A hair brush for preventing hair loss is provided. The hair brush of the current invention is comprised of a main body, a bristle body and a spike body. The main body of the brush is made of ABS (acrylonitrile-butadiene-styrene) polymer. The bristle body and the spike shape body are made of mixtures of anion emitting material, magnets and plastics such as silicon and polyurethane. Strength of the magnetic field generated from the bristle body and spike body is controlled to be 5 to 50 Gauss by controlling composition of carbon steel and strength of the magnetizer. Emitting anion concentration is controlled to be 400 to 700 each/cm3 by adjusting composition of anion emitting materials. Combing 10 cm2 area of scalp one minute a day for 30 days, number of hair loss a day decreased from over 100 each to less than 20 each.
