  • Patent number: 7536790
    Abstract: A hair cutting machine (10) having a handle (12) that contains an electromotive drive unit (49) and having a cutter head (16) that is disposed at the front handle end and, in the operating position of the handle (12), has a stationary blade (18) and an oscillating blade (20) disposed above it, the stationary and oscillating blades (18, 20) forming a cutting plane (22) that lies between the two blades (18, 20) and is inclined in relation to the longitudinal axis (24) of the handle (12). In the operating position of the handle (12), the cutting plane (22) is inclined downward in relation to the longitudinal axis (24) of the handle (12) and the oscillating blade (20) is disposed above the stationary blade (18), which makes it possible to produce a haircut that is comparable to a classic scissors cut (FIG. 9).

  • Patent number: 7504090
    Abstract: The wax product for treating or setting up a hairstyle or hairdo includes a composition containing at least one wax or wax-like substance, at least one non-volatile liquid hydrophobic oil and at least one volatile or easily volatilized hydrophobic substance that is a liquid or gas at room temperature. Because of the presence of the volatile substance in the composition a soft wax easily worked in the hair is obtained when the composition is applied to the hair. This soft wax hardens on the hair when the volatile ingredients evaporate. When the composition includes a propellant gas a wax with a larger surface area (wax snow) is produced, which is likewise easily worked into the hair and very effectively fixes or sets the hair.
