  • Patent number: 5524648
    Abstract: A combined brush and comb ("brush-comb") is used to apply tones, touches or streaks of hair treatment liquid to human hair. The brush-comb has a curved body portion terminating in a tip, which may be used to part the hair, and a head portion having comb tines and brush tufts positioned close to the tines. Each tine has at least one and preferably a plurality of grooves perpendicular to its axis to retain the liquid and to replenish the liquid to the brush tufts. In operation, the brush-comb head portion is dipped into a container of the liquid and then the head portion is pulled through the hair to apply touches of the liquid to selected areas of the hair.

  • Patent number: 5344463
    Abstract: 2-substituted-1-naphthols when coupled with an oxidation dye precursor in an oxidative dye system produce a long lasting intense color to hair. Use of such couplers makes available to the colorist novel oxidation hair dyes which surprisingly show a color shift to the red. Dyestuffs prepared through use of the 2-substituted-1-naphthol couplers are substantially more acid-fast compared to like dyestuffs using a 1-naphthol coupler. Compositions and a method of dyeing hair are also disclosed.

  • Patent number: 5314684
    Abstract: The hair fixative composition contains from about 2 to about 10 weight %, based on the weight of the composition, of a water-dispersible amorphous thermoplastic hair fixative polyester whose polymer chain is represented by the structure: ##STR1## wherein A is an aromatic dicarboxylic acid moiety, G is an aliphatic or cycloaliphatic glycol residue, on the average there being 5 to 8 sodiosulfo substituents per molecule. The fixative polyester is in colloidal suspension in the composition. The composition further contains from about 0.1 to about 3 weight %, based on the weight of the composition, of a copolymer containing dimethylpolysiloxane and organo-modified methylsiloxane moieties. Such amount is sufficient to cause the composition to spread out on a hair shaft when the composition is applied to same. The composition also contains from 0 to about 25 weight %, based on the weight of the composition, of a lower alcohol and sufficient water to bring the composition to 100 weight %.
