Increasing glutathione levels in melanocytes for the treatment of hair color loss
US Patent 8481762
Publication date: July 9, 2013
Assignee: L'Oréal

Described in this patent is how at least one compound that increases the level of glutathione in the melanocytes of hair follicles, and admixtures thereof with other active agents—selected from among active agents for combating desquamative conditions of the scalp, plant extracts having propigmenting activity, and active agents that slow hair loss and/or promote hair regrowth—are useful for preventing and/or limiting and/or stopping the development of canities.

Regulation of hair growth
US Patent 8481015
Publication date: July 9, 2013
Assignee: The Procter & Gamble Company

This invention relates to a topical skin care composition containing a safe and effective amount of a skin care active comprising agmatine, and its salt; an additional skin care active selected from the group consisting of BHT or BHA, hexamidine, cetyl pyridinium chloride, green tea catechins, phytosterols, ursolic acid, compounds derived from plant extracts, their salts and derivatives; and a dermatologically acceptable carrier for the agmatine composition. Such agmatine compositions reportedly can regulate hair growth and the condition of mammalian skin by topically applying the composition to the skin.

Friction-controlled fragrance encapsulation and film-forming compound to improve adherence of capsules on keratinous surfaces
WIPO Patent Application WO/2013/102013
Publication date: July 4, 2013
Assignee: L'Oréal, E. Alden-Danforth, W. Feuer, M White and N Williams

The present disclosure relates to an aqueous microcapsule composition including a plurality of microcapsule particles, a film-forming mixture and an aqueous solvent. Each microcapsule particle comprises a sol-gel material and a volatile oil-soluble active ingredient encapsulated by the sol-gel material. The film-forming mixture extends the efficacy of the volatile oil-soluble active ingredient encapsulated in the microcapsule particles by improving the adherence of the microcapsule particles to the substance to which the aqueous microcapsule composition is applied (e.g., a keratinous substance or a fabric). The aqueous microcapsule composition of the instant disclosure is well-suited for use in aqueous personal care products.

Nutritional ergothioneine and vitamin D2 for hair, nail and skin growth
WIPO Patent Application WO/2013/101713
Publication date:July 4, 2013
Assignee: Entia Biosciences, Inc. and M.S. Hausman

Disclosed in this patent are nutritional products, including food and/or beverage compositions, pharmaceutical and cosmetic preparations and methods of use, for the prevention, suppression and treatment of skin, hair, and nail conditions for the improvement of skin, hair and nail growth through the identification and/or use of stem cells, as well as maintenance of healthy tissues. Uses of ergothioneine and/or vitamin D to neutralize free radicals and improve skin, hair and nail growth are disclosed.

Process for altering the appearance of hair using a composition containing dyes and non-hydroxide bases
WIPO Patent Application WO/2013/098335
Publication date: July 4, 2013
Assignee: L'Oréal

Described in this patent are a composition and process for altering the appearance of hair by dyeing and reducing curl and/or frizziness of hair. Said composition includes: a) at least one non-hydroxide base, b) at least one protein denaturant different from a); c) at least one dye chosen from oxidative dye precursors and direct dyes; d) at least one thickening agent; e) optionally, at least one alkoxysilane comprising at least one solubilizing functional group; and f) optionally, at least one fatty substance. The process involves contacting the hair with the composition; optionally, rinsing the treated hair; optionally, drying the treated hair; smoothing the treated hair using a combination of heat and means for physically smoothing hair to form smoothed hair; optionally, shampooing the smoothed hair; and rinsing the smoothed hair.

Composition and process for reducing the curl and frizziness of hair
WIPO Patent Application WO/2013/098332
Publication date: July 4, 2013
Assignee: L'Oréal

Disclosed herein is a process for reducing curl and/or frizziness of hair comprising: (a) providing a composition for reducing curl and/or frizziness of hair, said composition comprising, in a cosmetically acceptable carrier: (i) at least one non-hydroxide base; (ii) at least one protein denaturant different from (a)(i); (iii) at least one alkoxysilane comprising at least one solubilizing functional group; and (iv) optionally, at least one fatty substance; (b) contacting the hair with the composition in (a) to form treated hair; (c) optionally, rinsing the composition in (a) from the treated hair;(d) optionally, contacting the treated hair with a conditioning agent; (e) smoothing the treated hair using a combination of heat and means for physically smoothing hair to form smoothed hair; (f) optionally, shampooing the smoothed hair; and (g) rinsing the smoothed hair.

Oxidative dyeing composition
WIPO Patent Application WO/2013/098208
Publication date: July 4, 2013
Assignee: Kao Germany GMBH

The present invention relates to an oxidative dyeing composition having especially mild properties to the scalp. The object of the present invention is an oxidative dyeing composition for hair comprising at least one dyestuff and Avena sativa (oat) meal extract.

Hair evaluation method and system
US Patent 8484155
Publication date: July 9, 2013
Assignee: Kao Corporation (Tokyo, JP)

According to this patent, a relational equation can be made between wave information on unpermed hair strands and evaluation values of the appearance of whole hair selected from among gloss of the whole hair, order of alignment of the hair strands, and frizziness of the hair strand from a plurality of subjects. Based on the relation equation, the appearance of whole hair of an arbitrary subject is evaluated from wave information on a hair strand of the arbitrary subject. This allows an objective evaluation of the gloss of whole hair, the order of alignment of hair strands, or the frizziness of the hair strand by a simple technique, and also allows an objective evaluation corresponding to cosmetic specialists' evaluations in terms of equivalent age.
