A head cover (800) has selectable size and location of at least one opening (812, 814) for exposure of a portion of a user's hair to an external hair treatment environment. The cover includes an impermeable outer surface that protects hair thereunder from an external hair treatment environment. A main opening (802) in the cover receives a user's head inserted into the cover. An opening (812, 814) on the cover, separate from the main opening, has an opening size selectable from selectable sizes and has an opening location selectable from selectable locations on the protective head cover. The opening (812, 814) selectively exposes a portion of the user's hair from under the cover to an external hair treatment environment while the cover protecting another portion of the user's hair from the external hair treatment environment.

A hair straightening device which in some embodiments may include an applicator and a hair press. The applicator may have a shaft with a handle and a hair hook. The hair press may have a first press member, a second hair press member, a first hinge assembly, and a cavity. The first press member may include a first press surface, a first elongated locking side, and a first elongated hinge side. The second press member may include a second press surface, a second elongated locking side, and a second elongated hinge side. The first hinge assembly may be configured to pivotally couple the first elongated hinge side of the first press member to the second elongated hinge side of the second press member. The cavity may be formed between the first press surface and second press surface when the press surfaces are moved proximate to each other.

The hair coloring appliance includes a flexible cap which is adapted and sized to fit against the head of the user, covering the user's hair. The cap includes a sealing band which seals the edge of the cap to the user's head. A vacuum pump assembly is connected to the cap as well as a color infusion assembly. A control system controls the vacuum assembly to create a vacuum in the cap volume and to permit infusion of color material when the desired vacuum has been created.
