## Background
CROSS-REFERENCE TO RELATED APPLICATION
This U.S. Non-Provisional Patent Application claims priority to U.S. Provisional Patent Application No. 62/719,721, filed on Aug. 20, 2018, the disclosure of which is incorporated by reference herein in its entirety.


FIELD OF THE INVENTION
The present invention relates to a hair brush for generating a wave hairstyle. More particularly, an exemplary embodiment of the present invention relates to a motorized brush for generating a wave hairstyle.
BACKGROUND
A wave or “waves” hairstyle is a type of hairstyle in which curls are brushed and flattened out, creating a ripple-like pattern. The hairstyle may be formed in a relatively short-cropped haircut and frequent brushing of the curls, which trains the curls to flatten out. Thus, a plurality of peaks and valleys may appear between the trained curls. Pomades and moisturizers can help hold the hair in place while preventing the hair from getting too dry during a process of forming the wave hairstyle. A do-rag may be worn to preserve moisture while compressing the hair and holding it in place, particularly when sleeping, during the process of forming the wave hairstyle. Thus, the formation of the wave hairstyle may be a relatively long process involving frequent brushing over an extended period of time. For example, brushing may take place over a period of several months to achieve a desired hairstyle.
Further, continued styling of hair may be carried out after the initial hairstyle is formed, as new hair continues to grow.
Both the initial styling and continued styling may be performed by a relatively stiff bristled brush. Thus, the process of forming and maintaining a wave hairstyle may be a time consuming process involving repeated brushing.

DETAILED DESCRIPTION
It will be understood that the terms “first,” “second,” “third,” etc. are used herein to distinguish one element from another, and the elements are not limited by these terms. Thus, a “first” element in an exemplary embodiment may be described as a “second” element in another exemplary embodiment.
“About” or “approximately” as used herein may be inclusive of the stated value and means within an acceptable range of variation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (e.g., the limitations of the measurement system). For example, “about” may mean within one or more standard variations, or within ±30%, 20%, 10%, 5% of the stated value.
Descriptions of technical features or aspects of an exemplary embodiment of the present disclosure should typically be considered as available and applicable to other similar features or aspects in another exemplary embodiment of the present disclosure. Accordingly, technical features described herein according to one exemplary embodiment of the present disclosure may be applicable to other exemplary embodiments of the present disclosure, and thus duplicative descriptions may be omitted herein.
Exemplary embodiments of the present disclosure will be described more fully below (e.g., with reference to the accompanying drawings). Like reference numerals may refer to like elements throughout the specification and drawings.
The motorized hairbrush described herein may be employed for forming, developing, or maintaining a wave or “waves” hairstyle, which is a type of hairstyle in which curls are brushed and flattened out, creating a ripple-like pattern. The hairstyle may be formed in a relatively short-cropped haircut and frequent brushing of the curls, which trains the curls to flatten out. Thus, a plurality of peaks and valleys may appear between the trained curls. The formation of the wave hairstyle may conventionally be a relatively long process involving frequent brushing over an extended period of time. For example, brushing may take place over a period of several months to achieve a desired hairstyle. However, the motorized hairbrush described herein decreases an amount of time for forming a wave hairstyle by more rapidly training a user's hair into a desired style of configuration. The motorized hairbrush described herein also reduces an amount of time and a number of brush strokes needed to effectively maintain a wave hairstyle. The vibration formed by the vibrating motors increases a rate at which a user's hair is trained or styled, while reducing an amount of effort required by a user to create or maintain a desired hairstyle.
