  • Patent number: 11000116
    Abstract: A hair brush includes a handle defining a longitudinal axis and a brush head having at least two longitudinal primary arms extending longitudinally from the handle and disposed in lateral spaced relation to define a longitudinal gap therebetween. Each of the longitudinal primary arms includes a pair of longitudinal rear spines disposed in lateral spaced relation, a single longitudinal intermediate spine extending from the rear spines, and a pair of longitudinal forward spines disposed in lateral spaced relation and extending from the intermediate spine. Hair engaging bristles are disposed on each of the rear spines, the intermediate spines and the forward spines. The at least two longitudinal primary arms are substantially flexible to conform to the contour of the user's head. A container containing a hair treatment agent such as dry shampoo may be releasably mounted to the handle.

  • Patent number: 10925371
    Abstract: A hair brush adapted to impart both a straightening effect and a curling effect on a length of hair includes first and second members. The first member includes a first handle and a first brush head having an inner row of centrally disposed primary teeth, an outer row of bristles mounted on each side of the centrally disposed primary teeth, and a thermal conductive element. The thermal conductive element defines an arcuate surface configured for imparting a curl within a lock of hair. The second member includes a second handle, a second brush head having a second head frame defining a longitudinal channel, and an elongate member having a wiper segment disposed on each side of the longitudinal channel, and configured to engage the length of hair to facilitate one of straightening of the length of hair or removing substances from the length of hair.

  • Patent number: 9232839
    Abstract: A hair curling apparatus includes a handle, a barrel depending from the handle, and dimensioned to accommodate a lock of hair wrapped thereabout and a clamp releasably mounted relative to one of the barrel or the handle. The clamp includes a spoon which is adapted to move relative to the one of the barrel or the handle between a closed position and an open position. The spoon engages the lock of hair when in the closed position. The curling iron apparatus has both clamp and clampless capabilities, thus providing the user with styling flexibility.

  • Publication number: 20150034118
    Abstract: A hair treatment accessory for use with a hair styling apparatus includes a substrate base for mounting to a hair styling apparatus and a treatment agent disposed on the substrate base. The treatment agent is applied to one of the hair or skin of a subject during use of the hair styling apparatus. The treatment agent may include a conditioning, strengthening, repairing or revitalizing fluid. The treatment agent may include a conditioning oil. The conditioning oil may include ARGAN oil with or without silicon. The substrate base may include an irregular surface dimensioned to assist in retention of the treatment agent on the substrate base. The irregular surface may include open cells or channels. The irregular surface may be formed through a sintering process.
