Hair straightener

Abstract

A hair straightening and / or pressing device for straightening and / or pressing coarse, thick, ethnic, kinky or curly hair can include two arms connected pivotally at one end. The arms can have opposing surfaces that can be heated. The heated surfaces can be featureless or include features. One or both surfaces can have rows of closely spaced, parallel blade shaped tines extending across substantially the entire width of the surface from one side of the device to another side of the device. The hair straightening device can have at least two different temperature settings selectable by a user. In certain implementations, one temperature setting may be lower than the other two settings and at a temperature that is not optimal for straightening hair. The other two temperature settings may be set to a temperature that is optimal for straightening hair of different types.

AI Technical Summary

Benefits of technology

The patent text describes the technical effects of a new hair straightening device with blades. The device can be heated to different temperatures to make sure that all types of hair can be easily straightened. This means that it takes less time and fewer passes to get the desired results. The new device also reduces sticking and tangling, which can make hair straightening easier, especially for thick, coarse, ethnic, curly, and kinky hair.

Problems solved by technology

Thick, coarse, ethnic, curly, and / or kinky hair is particularly difficult to straighten properly with a typical flat plate iron type of hair-straightener.

In some instances, hair with these types of textures can cause sticking or tangling in the hair straightening device during straightening.

Thicker hair may also not be evenly or properly heated or straightened by the flat plate iron type device.

Thus, for example, some hair that is particularly coarse, curly and / or kinky can be more difficult to straighten by passing a known pressing type straightening iron (e.g., the typical flat plate iron) over the hair.
