Methods and kits for treating hair or preventing damage in the relaxing of hair are disclosed herein. Hair that is damaged during a relaxing treatment with hydroxide-containing relaxing agents, can be treated with formulations containing one or more active agents. The active agent formulations can be applied simultaneously with the hair relaxing formulation, or optionally applied immediately following application of the relaxing formulation, to reduce damage and breakage. Use of the active agent formulation along with a relaxing treatment can be used to control the level of curl achieved or retained in the relaxed hair, as compared to the natural amount of curl in the untreated hair.

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 treatment method for curling a lock of hair using a hair holder is provided. The hair holder includes a tubular body into which a lock of hair can be inserted from an opening at a first end of the tubular body toward an opening at a second end thereof, and the tubular body is configured to be capable of being rolled up. The hair treatment method includes inserting a lock of hair into the hair holder, rolling up the tubular body together with the lock of hair inserted in the tubular body so that a large diameter portion that has a tubular shape and forms an outer circumferential portion and a small diameter portion that is located inside the large diameter portion and has a space between the small diameter portion and the large diameter portion are formed, and performing curling while maintaining this wound state.

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.

A hair care device for use in untangling hair includes a body portion and a plurality of substantially parallel flexible bristles made of soft plastics material and projecting from the body portion. The bristles are arranged such that over at least a part of the area of bristles, some of the bristles are of shorter length. The bristles and the shorter length bristles are interspersed over the at least part of the area of bristles.

A method for coloring hair on a human head using a blow dryer is provided. According to the method, the hair is separated into sections of different shape (e.g., rhombic, square, triangular, horseshoe-shaped, etc.). Then, subsections of hair are isolated in each section. Each subsection of hair is grabbed and pulled (in a direction of a cut line of the hair) with one hand of a hairdresser, and different (e.g., short, medium-length, and long) layers of hair are blown out of the subsection of hair by an air flow from the blow dryer held in another hand of the hairdresser. After that, at least one of the blown-out layers of hair is fixed (e.g., with a clamp) and colored. The hair thus colored is then rinsed and treated according to a post-coloring recipe.

An improved system and method for an eye patch can comprise a patch and a pad. The patch can be substantially flat and flexible. Furthermore, the patch can comprise a bottom surface, a top surface, and a concave edge. The bottom surface can comprise an adhesive capable of temporarily attaching to a skin. The concave edge can be on one side of the patch. Additionally, the concave edge can substantially match the anatomical curve of a human's eye socket. The pad can be a raised portion on the patch that can be capable of pushing upper natural eyelashes upward when a client closes her eyes. The pad can be attachable along the concave edge.
