Abstract

The present invention relates to a volume hair dryer brush. As one non-limiting example, the invention relates to a volume hair dryer brush with an roughly elliptical barrel. As another non-limiting embodiment, the invention relates to a volume hair dryer brush with a roughly elliptical barrel where the density of the bristles and tufts on the narrow sides of the ellipse are less than the density of the bristles or tufts on the long sides of the ellipse. As an alternative non-limiting embodiment, the invention relates to a volume hair dryer brush where the narrow sides of the ellipse lack bristles or tufts whatsoever. As a further non-limiting embodiment, the invention relates to a volume hair dryer brush with an elliptical barrel where the barrel is coated in whole or in part, including but not limited to having coating in the shape of strips at any location on the barrel. The invention also includes, but is not limited to, a volume hair dryer brush having an elliptical barrel wherein the handle that attaches to the barrel is detachable.

Dependent claims

A volume hair dryer brush comprising:

a barrel having an elliptical cross section, wherein the brush emits hot air, wherein, when viewed from top of the brush, the barrel has two long sides each having
a fixed length I and two narrow sides each having a fixed length n, wherein all sides of the barrel have a curved surface, wherein the fixed length n of the narrow sides of the barrel is less than the fixed length I of the long sides of the barrel, wherein both of the long sides of the barrel have fixed bristles and/or tufts,
wherein both of the narrow sides of the barrel do not have any bristles and/or tufts,
wherein at least one of the sides of the barrel is heated solely by the hot air of the brush,
wherein at least a portion of the barrel has texture and/or a coating, and
wherein the texture and/or coating is located only on the narrow sides of the barrel.
