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. ## Claims ### Claim 1 A hair grooming apparatus comprising: a vacuum mechanism; a vacuum chamber in fluid communication with the vacuum mechanism, the vacuum chamber comprising: a first opening positioned at a first end of the vacuum chamber, having a first cross-sectional area, and arranged to accommodate an insertion of a section of hair; a second opening positioned at a second end of the vacuum chamber opposite the first end of the vacuum chamber; a wall extending from the first opening to the second opening and defining an interior bore; and an air pocket formed along a section of the interior bore, the section of the interior bore extending from a first location positioned proximate to the first opening and having a second cross-sectional area to a second location positioned between the first location and the second opening and having a third cross-sectional area, wherein the second cross-sectional area is greater than both the first cross-sectional area and the third cross-sectional area. ### Claim 2 (depends on 1) The hair grooming apparatus of claim 1, further comprising: a vacuum canister, wherein the vacuum mechanism is positioned within the vacuum canister; and a hose positioned between the vacuum canister and the vacuum chamber. ### Claim 3 (depends on 1) The hair grooming apparatus of claims 1, wherein cross-sectional areas of the section of the interior bore varies continuously from the first location to the second location. ### Claim 4 (depends on 3) The hair grooming apparatus of claims 3, wherein the section of the interior bore is generally tapered from the first location to the second location. ### Claim 5 (depends on 1) The hair grooming apparatus of claim 1, further comprising: a heated air chamber in fluid communication with the vacuum chamber; a heating element; and a fan configured to blow air over the heating element and into the heated air chamber. ### Claim 6 (depends on 5) The hair grooming apparatus of claim 5, wherein the vacuum chamber, heated air chamber, heating element, and fan are positioned within a hand-held unit. ### Claim 7 (depends on 6) The hair grooming apparatus of claim 6, wherein the vacuum chamber includes at least one aperture positioned proximate to the first opening through which the heated air chamber is in fluid communication with the vacuum chamber. ### Claim 8 (depends on 6) The hair grooming apparatus of claim 6, wherein the heated air chamber at least partially surrounding the vacuum chamber and in fluid communication with vacuum chamber to introduce heated air to the vacuum chamber. ### Claim 9 (depends on 8) The hair grooming apparatus of claim 8, wherein the fluid communication between the heated air chamber and the vacuum chamber is formed by at least one aperture in the wall positioned proximate to the air pocket. ### Claim 10 (depends on 9) The hair grooming apparatus of claim 9, wherein the at least one aperture is a plurality of apertures that are positioned generally equally about a perimeter of the wall. ### Claim 11 (depends on 8) The hair grooming apparatus of claim 8, wherein hot air is introduced to the vacuum chamber at the air pocket. ### Claim 12 (depends on 11) The hair grooming apparatus of claim 11, wherein the vacuum chamber further comprises a front wall generally perpendicular to the wall defining the interior bore located proximate to the air pocket. ### Claim 13 (depends on 12) The hair grooming apparatus of claim 12, further comprising at least one aperture positioned in the front wall to introduce hot air to the vacuum chamber at the air pocket. ### Claim 14 (depends on 13) The hair grooming apparatus of claim 13, wherein the at least one aperture is a plurality of apertures that are positioned generally equally about the front wall. ### Claim 15 (depends on 14) The hair grooming apparatus of claim 14, wherein the plurality of apertures direct an introduction of heated air to the vacuum chamber at the air pocket in a direction substantially parallel to a flow of vacuum air through the vacuum chamber. ### Claim 16 (depends on 5) The hair grooming apparatus of claim 5, further comprising at least one vane extending inward into the interior bore of the vacuum chamber from the wall. ### Claim 17 (depends on 16) The hair grooming apparatus of claim 16, wherein the at least one vane further extends along a length of the wall of the vacuum chamber. ### Claim 18 (depends on 5) The hair grooming apparatus of claim 5, wherein a plurality of vanes extending inward into the interior bore of the vacuum chamber from the wall and further extending along a length of the wall of the vacuum chamber. ### Claim 19 (depends on 18) The hair grooming apparatus of claim 18, wherein the plurality of vanes are arranged equally along an inner circumference of the vacuum chamber. ### Claim 20 (depends on 1) The hair grooming apparatus of claim 1, further comprising a flow conditioner. ### Claim 21 (depends on 20) The hair grooming apparatus of claim 20, wherein the flow conditioner is a separate component inserted into the vacuum chamber. ### Claim 22 (depends on 20) The hair grooming apparatus of claim 20, wherein the flow conditioner is integrally formed into the vacuum chamber. ### Claim 23 A hair grooming apparatus comprising: a vacuum mechanism; a vacuum chamber in fluid communication with the vacuum mechanism, the vacuum chamber comprising: a first opening arranged to accommodate an insertion of a section of hair; and a second opening opposite the first opening; and a flow conditioner associated with the vacuum chamber, the flow conditioner having a variable cross-section, wherein the flow conditioner includes a first section with a cross-sectional area decreasing from a first end of the flow conditioner towards a middle of the flow conditioner and a second section with a cross-sectional area increasing from the middle of the flow conditioner towards a second and opposite end of the flow conditioner. ### Claim 24 (depends on 23) The hair grooming apparatus of claim 23, wherein the decrease cross-sectional area and increase in cross-sectional area is both linear. ### Claim 25 (depends on 23) The hair grooming apparatus of claim 23, wherein the decrease cross-sectional area and increase in cross-sectional area is both nonlinear. ### Claim 26 (depends on 23) The hair grooming apparatus of claim 23, wherein the first end of the flow conditioner is coupled to the second opening of the vacuum chamber. ### Claim 27 (depends on 23) The hair grooming apparatus of claim 23, wherein the flow conditioner is a separate component inserted at least partially into the second opening of the vacuum chamber. ### Claim 28 (depends on 23) The hair grooming apparatus of claim 23, wherein the flow conditioner is integrally formed into the vacuum chamber proximate to the second opening. ### Claim 29 (depends on 23) The hair grooming apparatus of claim 23, further comprising: a heated air chamber in fluid communication with the vacuum chamber;
