A method of selecting skin treatment regimens, ingredients and compositions that includes measuring the levels of particular small molecule metabolites on skin both before and after product application and testing for a change in small molecule metabolite levels is disclosed.

This disclosure relates to hair styling compositions and processes, and more particularly to compositions for disentangling or crosslinking hair that are useful in hair styling processes.

A water-in-oil personal care emulsion with water droplets size below 20 microns, the droplets containing solubilized cystine. A process of making an emulsion is also described.

A hair coloring method that has a better property of keeping color quality, hardly damages hair, reduces skin damage and is free of paraphenylenediamine when performing hair dye comprises a step of applying a mixture of the following (A) and (B) in a predetermined ratio: (A) a hair coloring agent comprising at least a basic dye, an HC dye, a second amino acid, a first cationic surfactant, a thickener, an oil agent, a first pH adjuster and a wetting agent, wherein the hair coloring agent has a pH of 6.8 or more, and (B) a hair cosmetic comprising at least an alkaline agent, a first amino acid, a higher alcohol having 12 to 22 carbon atoms, a surfactant, and a thickener; a step of providing a predetermined time after applying; and a step of applying a cuticle care agent after the predetermined time.

The present disclosure concerns colouring agents for keratinous fibres, in particular for human hair, whichwith respect to its weightcontain at least one compound selected from the group formed by oxidative dye precursors, direct dyes and mixtures thereof, from about 0.1 to about 5% by weight of dicarboxylic acid(s) containing from about 2 to about 10 carbon atoms and/or salt(s) of this(these) acid(s), from about 20 to about 95% by weight of water, and less than about 0.1% by weight of peroxy compound(s), to produce oxidative colouring agents with improved protection of fibres.

A method of lyophilizing exosomes using a cryoprotectant comprising methionine, mannitol and trehalose is disclosed. The lyophilized exosome product shows a good appearance which maintains a porous sponge shape without forming ice crystals. In addition, the lyophilized exosome product can be applied to a pharmaceutical composition, a skin external preparation and a cosmetic composition. For example, the lyophilized exosome product can be used as a solution obtained by simply mixing it with a diluent.

The present disclosure concerns a hair care agent for the oxidative colouring or bleaching of hair, as well as a gentle method for the oxidative colouring or bleaching of hair, in which keratinous fibres are protected from oxidative influences.

The invention relates to a hair restorer preparation or food supplement (100, 100a-100c) for oral administration, comprising L-cysteine and zinc, wherein the hair restorer preparation respectively food supplement (100, 100a-100c) comprises copper, calcium, magnesium, silicium and cholecalciferol, and wherein the composing substances or substance compositions (S-Z) composing the hair restorer preparation respectively food supplement (100, 100a-100c) are determined in their dosage by means of tests and/or measurements and/or questionnaire evaluations (A-H) and are adaptable to the individual organic nutrients supply requirements of a female or a male customer (200, 200a-200d).

The present disclosure relates to compositions containing a natural extract(s) and their fraction(s) and the use of such compositions for treatment of skin, hair and nail. For example, the present disclosure relates to compositions containing an aqueous extract of (i) Yacn leave, (ii) Amor Seco leave, or (iii) Porphyridium biomass, or a combination thereof and a pharmaceutically or cosmetically acceptable carrier use on hair skin and nails for cosmetic purposes.

The present invention relates to a composition that acts prior to the action of a tooth whitening composition or tooth whitening patch, the composition containing an oral cavity stimulation alleviating component able to reduce stimulation by the tooth whitening composition or patch. The present invention also relates to a tooth whitening kit whereby oral cavity stimulation is alleviated. The composition that acts prior to the action of a tooth whitening composition or patch of the present invention provides an outstanding tooth whitening effect while alleviating pain by mitigating intra-oral stimulation brought about by the rapid action of a tooth whitening component due to a tooth whitening component active agent.
