Definitions

  • the present disclosure relates generally to a head for hair tools, and more specifically to a hair tool head having an oval cross section where a portion of the back of the hair tool head is open.
  • the hair tool head may be used with heated and non-heated hair tools, including but not limited to traditional hair brushes, hot air brushes, hair dryers, diffusers for hair dryers, curling irons, straightening irons, and hair rollers.
  • the present disclosure further relates to methods of using the disclosed hair tool head to reduce drying time for hair, reduce hair frizz, reduce damage to hair occurring during hairstyling and/or hair drying, increase the length of time that hair keeps a curl and/or a flip (the “set” of the curl or flip), and lessen user fatigue during the hairstyling process.
  • the head of hair brushes and other hair styling tools have either a flat surface that interacts with the hair, such as that associated with a paddle brush, or the heads are cylindrical in shape.
  • hair tool heads that are cylindrical are right circular cylinders having normally circular cross sections of equal area.
  • the term “normally” used herein means “in a direction normal to a tangent at a specified point.”
  • An example of a hair tool that has a right circular cylindrical head is a traditional curling iron or a hair roller.
  • the “round brush” has a hollow, cylindrical head with a round (circular) cross section that is the same diameter throughout the length of the head.
  • Right circular cylindrical heads are also commonly used for hot air brushes.
  • Hot air brushes are hair appliances that force hot air through a brush head that is vented.
  • some hair tools that are known in the art have a head that is in the shape of an oval cylinder having normally oval cross-sections of equal area.
  • ovular hot air brushes and ovular (manual) hair brushes are available commercially.
  • cylindrical brush heads are round or ovular, are to create curls or flips during the hairstyling and/or hair drying process.
  • the user winds a portion of hair around the perimeter of the brush head by turning the tool, typically at least one full rotation (and often several rotations depending on the length of the hair). The user then releases the tension on the wound hair and removes the brush head from the hair. Because the hair is typically heated during this styling process, the winding of the hair can create curls or, if used only primarily on the ends of the hair, a flip.
  • Cylindrical brush heads typically have bristles that cover the full surface of the brush head, i.e., the bristles surround the entire perimeter of the hair tool head. During styling with such tools, the bristles are thus continually in contact with the hair.
  • the use of hair tools have cylindrical brush heads often creates tangles, which can sometimes be intractable. Tangling can occur for many reasons, including but not limited to situations where the hair is wound too tightly around the brush head, where each layer of hair wound around the brush head is not uniformly taut, where the hair wound around the brush hair is distributed unevenly along the length of the brush head, and/or where the hair becomes otherwise snagged in the bristles.
  • the tangling from typical cylindrical brushes can cause discomfort during the hairstyling process as well as broken hair strands. Tangling further also can affect the shape and “setting” of the curl and flips as well as slowing down the hair drying and hair styling process.

Such material is present at the front and both sides of the hair tool head. Because at least a portion of the back of the hair tool head is open, the material is thus absent from the open portion of the head. As noted above, in some embodiments, most or almost all of the back of the head is open, which has the environmental advantage of reducing the amount of material required for the hair tool head.
  • the hair tool heads of the present invention have multiple advantages over conventional cylindrical hair tool heads.
  • the lighter weight will make it more likely that the user can execute curls and flips.
  • the overall weight of the tool also will be lighter.
  • the tool will thus be less likely to pull and deform the shape of the curls and flips, allowing these effects to last longer compared to conventional hair tool heads.
  • the lighter weight will also help reduce fatigue during hair styling and be particularly useful for those with arthritis, carpal tunnel, and other injuries or conditions that may impact hand function.
  • the hair tool heads of the present invention will allow better air flow given the open portion of the back of the hair tool head.
  • the open portions of the hair tool heads of the present invention will allow heat to penetrate the hair more quickly when heat is applied as part of the styling process, enabling faster styling of the hair compared to conventional hair tool heads.
  • the faster drying time and/or styling time associated with the present invention will mean less overall heat damage to the hair.
  • the head of the present invention thus is likely to preserve hair strength, reduce hair frizz associated with heat damage, and create curls or flips that set better and last longer compared to using hair tool heads that do not have an open back portion.
  • the hair tool heads of the present invention also are less likely to become tangled in the hair. A portion of the hair tool head is missing; this means that are fewer surfaces and/or bristles on which hair may get caught. The head of the present invention thus is less likely to cause damage to the hair and will lessen the pulling and tugging force needed during the hair drying and/or hair styling process.
  • the head of the present invention will also require less movement to create the hair style required. Unlike using brush heads that have a continuous circumference or perimeter, the user working with the hair tool head of the present invention will not necessarily need to turn the tool a full rotation since the operative portion of the head is only at the front and sides of the head.
  • the oval cylindrical shape of the hair tool head of the present invention also has advantages. Such a head can make closer contact at the scalp given its oval cross-section, allowing the hair at the scalp to be lifted as well as heated and/or dried more easily. Additionally, the different curvatures of the oval can create diversity in the shape of the hair curls and flips, i.e., tighter or looser curls or flips may be created depending on the portions of hair tool head that are used on the hair. When the hair tool head is a concave oval cylinder, a user may also create a tighter curl at end of the hair by winding the ends hair around the middle portion of the concave cylinder, i.e., at its smallest perimeter.
  • the inventive hair brush heads thus can be used as part of methods to reduce drying time for hair, reduce hair frizz, reduce damage to hair that is incurred during hairstyling and/or hair drying, increase the length of time that hair keeps a curl and/or a flip, and/or lessen user fatigue during the hairstyling process.
