The invention relates to a device for treating the hair including a housing for receiving a cosmetic product refill, a heating element for the hair to be treated, and a device that prevents the reception of the cosmetic product refill in the housing, depending on the temperature of the heating element.

A hair styling device and methods are disclosed. The device has a first blade section comprising a first blade section heating element having a first heating element surface. The device has a second blade section rotatably coupled to the first blade section via a pivoting device and configured to rotate about a pivot axis, wherein, the second blade section comprises, a second blade section heating element having a second heating element surface. The pivot axis is not co-planar with the first and second heating element surfaces.

A hair treatment apparatus includes a base and a sidewall in direct contact with and extending from the base. The base and sidewall define a cavity configured for receiving a liquid. The hair treatment apparatus further includes a lid coupled to the sidewall opposite to the base, the lid defining an adjustable aperture configured for receiving a portion of hair for treatment in the liquid. The lid includes a first ring, a plurality of plates, and a second ring. The first ring is configured to releasably engage the sidewall and define a central axis. The plurality of plates extend from the first ring toward an aperture, each of the plurality of plates includes a pin. The second ring defines a plurality of slots to receive the pins. Rotation of the second ring causes the plurality of plates to extend toward the longitudinal axis to reduce the diameter of the aperture.

Disclosed are hair styling compositions comprising at least two latex polymers, wherein at least one latex polymer is a film-forming polymer. The composition is capable of forming a film having certain properties on a substrate. Methods of styling the hair are also disclosed.

Disclosed are hair styling compositions comprising at least two latex acrylate polymers, wherein at least one latex acrylate polymer is a film-forming polymer. Methods of styling the hair are also disclosed.

Disclosed are hair styling compositions comprising at least two latex polymers chosen from acrylate and polyurethane polymers, wherein at least one latex polymer is a film-forming polymer. Methods of styling the hair are also disclosed.

A hair twisting system and method can include: a frame, the frame including a frame inner surface, a frame outer surface, and a frame front surface; strings extended between portions of the frame interior surface, the strings define areas between the strings, the strings providing woven moveable intersections, the strings configured to be: pressed down into hair towards a scalp, and then simultaneously moved out away from the scalp while being rotated until the strings disengage from the hair for creating twisted locks; and a handle coupled to the frame, the handle including side structures, the side structures providing an interior griping surface between the side structures and an exterior griping surface.

A method of styling hair that includes the process of weaving and wrapping an ornamental hair device around and through an individual's hair to generate a stylish wrap or display of the user's hair.

Disclosed are hair styling compositions comprising at least two latex polyurethane polymers, wherein at least one latex polyurethane polymer is a film-forming polymer. Methods of styling the hair are also disclosed.

A cosmetic composition comprising a thickening polymer having hydrophobic and hydrophilic portions, a non-ionic surfactant, a neutralizing agent, a non-ionic kosmotrope and water. Also, a hair colorant formulation obtained from mixing said composition and a hair dye. Also, the use of said formulation for coloring and/or sculpting hair.
