Abstract
A hair grooming apparatus includes a vacuum mechanism and a vacuum chamber that is in fluid communication with the vacuum mechanism. The vacuum chamber includes a first opening positioned at a first end of the vacuum chamber with a first cross-sectional area and arranged to accommodate an insertion of a section of hair and a second opening positioned at a second and opposite end of the vacuum chamber. The vacuum chamber further includes a wall extending between the first and second openings and defining an interior bore. An air pocket is formed along a section of the interior bore extending from a first location located proximate to the first opening with a second cross-sectional area to a second location positioned between the first location and the second opening with a third cross-sectional area. The second cross-sectional area is greater than both the first cross-sectional area and the third cross-sectional area.
