Abstract: A straightening device and a method for using a straightening device for treating coarse, thick, ethnic, or curly hair. The straightening device includes a first arm and a second arm pivotally coupled at proximal ends. The arms have opposing surfaces that may be heated or contain features that are specifically dimensioned and aligned.

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.

Abstract: A hair curling iron for curling, styling or making wavy hair can include a handle and a barrel portion. The barrel portion can have various shapes, such as a conical, cone, or corrugated shape. The surface of the barrel portion can be textured. Features or protrusions can be integrally formed as part or within the surface of the barrel. The features can be diamond-shaped dimples. The barrel portion can also include different sections configured to be heated to different temperatures.
