The present disclosure relates to an active ingredient composition for the care and surface modification of human hair. In particular, the present disclosure relates to a cosmetic composition for treating a keratinous material comprising a) at least one organic silicon compound and b) a cationic surfactant, the cosmetic composition being particularly suitable for caring for damaged hair.

Hair improvement compositions comprising covalent conjugates of a polypeptide and a hydrophilic polymer, or a polysaccharide and a hydrophilic polymer, or both, are provided herein. Methods for improving one or more physical characteristics of hair using the described compositions are also provided. The improvements can be semi-permanent.

Described herein is a hair care composition including from about 0.01% to about 20% of a lipid being one or more unsaturated fatty materials chosen from unsaturated fatty acids, unsaturated fatty alcohols, and mixtures thereof. The unsaturated fatty material has a Log P of less than 8. The hair care composition also includes from about 0.01% to about 10% of a fatty acid monoester of a polyol, a saturated fatty alcohol, an ester of a saturated fatty alcohol, and mixtures thereof. The molecule of the fatty acid component of the fatty acid monoester includes a linear or a branched carbon chain with 10 to 22 carbon atoms. The fatty acid monoester of a polyol has a log P of less than 8. The molecule of the fatty alcohol includes a linear or branched carbon chain with 8 to 22 carbon atoms. The hair care composition also includes a non-aqueous volatile solvent.

A method for the treatment of hair that includes the following steps: providing a pretreatment solution that includes a bis amino compound having a α-Hydroxy acid attached thereto; causing the pretreatment solution to react such that polymeric chains are formed; forming the polymeric chains into a biofilm; exposing the mixture to at least one hair; and wherein the biofilm defines a lattice structure.

The subject of the present invention is a compound of formula (I) below, the addition salts thereof, the dimer thereof and also the organic or inorganic acid salts thereof, the optical isomers thereof, the geometric isomers thereof, and the solvates thereof such as hydrates: (I) These compounds are sensitive to pH and of use for the treatment of keratin fibers, such as human keratin fibers and in particular the hair. ##STR00001##

The invention relates to a method for obtaining an aqueous extract of Anethum graveolens, enriched with small RNAs having a maximum length of 150 nucleotides, from a plant material, said method comprising the following steps: a) aerial parts of dill is brought into contact with water; b) tetrasodium ethylenediaminetetraacetic acid (EDTA) is added at a pH of between 10.5 and 11; c) the pH of the mixture obtained in b) is then adjusted to a value of between 6 and 8; d) the mixture obtained in c) is purified; and e) the pH is checked and readjusted if necessary to a value of between 6 and 8. The invention also relates to an aqueous extract of Anethum graveolens, enriched with small RNAs having a maximum length of 150 nucleotides, obtained by the method.

A hair rejuvenating lotion applied to a user's hair to treat and relieve symptoms caused by seborrheic dermatitis. Through use of plant extracts and other supplemental active ingredients, the hair rejuvenating lotion restores hair to a healthy condition, retains color and prevents hair loss. The plant extracts included are from the genera echinops, alchemilla, staphylea, and scorzonera, as well as the plants sophora japonica and nettle. The other supplemental active ingredients include sulfur, ammonium chloride, lead acetate, and castor oil. The base of the hair rejuvenating lotion consists of distilled water, glycerin, and ethyl alcohol. The plant extracts from the genera echinops, alchemilla, staphylea, scorzonera are dissolved into the ethyl alcohol to create a tincture solution. The tincture solution is mixed with the distilled water, glycerin, sulfur, sophora japonica extracts, nettle extracts, ammonium chloride, and castor oil to form the hair rejuvenating lotion.

The disclosure relates to cosmetic compositions for treating, caring for, and/or conditioning keratinous substrates, the compositions comprising branched alkanes, dimethiconols, silicones other than dimethiconols and having a viscosity at 25° C. of greater than or equal to 200×10.sup.−6 m.sup.2/s, and non-silicone fatty compounds other than the branched alkanes. The disclosure also relates to a cosmetic treatment process using this composition, and also the use of said composition for conditioning and/or caring for keratinous substrates.

The present disclosure relates to an active ingredient composition for the care of human hair. More particularly, the present disclosure relates to a cosmetic composition for treating a keratinous material, wherein the cosmetic composition is a fluid and comprises at least one organic silicon compound and comprises at least one polyvalent metal cation, the cosmetic composition being particularly suitable for caring for damaged hair.
