Provided are hair treatment compositions comprising one or more polysaccharides and their use in improving hair strength.

The present invention relates to a solid phase cosmetic composition comprising a freeze-dried component of a composition comprising a functional component and a basic amino acid. A solid phase component according to the present invention has excellent re-dissolvability, and exhibits insignificant changes in the hardness and pH of the composition for dissolving the solid component even after re-dissolution, and thus a cosmetic having excellent stability can be provided.

A composition and a process for modifying hair are disclosed. The process includes coating hair fibers with a composition comprising propylene carbonate and a glycol selected from at least one of propylene glycol, 1,3-propane diol, dipropylene glycol, tripropylene glycol, and mixtures thereof and contacting the coated hair with a heating appliance at a temperature of at least 150° C. for a sufficient time to modify the hair fibers.

Keratin protein cosmetic compositions are provided that include at least one keratin protein derived from human hair and a base cosmetic solution. Methods of treatment are also provided.

Provided are method for using phytic acid (PA), alone or in combination with glucono-delta-lactone (GL) to strengthen and/or repair hair.

The present invention relates to a polymer comprising repeating units derived from at least one first monomer (monomer A) which is a molecule comprising a thiolactone ring and an ethylenically unsaturated, polymerizable double bond, and at least one second monomer (monomer B) which is N-vinyl pyrrolidone. Furthermore the present invention relates to a modified polymer, the structure of which is identical to the structure of the said polymer apart from the only difference, which is that all or at least some of the thiolactone moieties of the said polymer are modified by opening the thiolactone ring with a substance selected from the group consisting of ammonia, a primary amine, 2-amino-1-ethanol and L-lysine, wherein the N-atom of said substance is binding to the carbonyl group of the opened thiolactone ring. Furthermore, the present invention relates to a process for making the modified polymer and to the use of the polymer or of the modified polymer for treating hair.

Compositions and formulations for hair treatment are provided herein. Methods for hair treatment, such as methods for preventing or treating hair loss or hair thinning, are also provided herein. The methods may promote hair growth, hair restoration or hair thickening, or increase hair density or hair growth rate.

A natural hair product for improving and restoring the condition of hair, and promoting the strength and growth of the hair, includes filtered water, burdock powder, stinging nettle powder, peppermint, horsetail powder, lavender flowers, and hibiscus flowers, in a base of olive oil, avocado oil, vitamin E, and lavender oil. If desired, the hair preparation may also include rosemary and fenugreek powder. The method of making the hair product is also disclosed.

The object of the present invention concerns a hair restructuring association comprising or alternatively consisting of: (a) a quaternary ammonium salt of formula (I) and (b) at least one sulpho-derivative of vegetable fatty acids, wherein R.sub.5, R.sub.6 are independently chosen between hydrogen and a radical R.sub.0, R.sub.0 consists of the following structure of formula (II), R.sub.1 is chosen from the group consisting of: hydrogen, methyl, isopropyl, sec-butyl, isobutyl, ethylenemethylthio, benzyl, para-hydroxybenzyl and 3-methylene-1H-indole, R.sub.2, R.sub.3, R.sub.4 are independently chosen from the group consisting of: methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl and tert-butyl, mX.sup.− is chosen from the group consisting of: formic acid, acetic acid, unsaturated monocarboxylic acids, adipic acid, aldaric acid, oxalic acid, phthalic acid, azelaic acid, sebacic acid, malonic acid, succinic acid, tartaric acid, glutaric acid, pimelic acid, maleic acid, malic acid, fumaric acid and suberic acid, isocitric acid, citric acid, fatty acids, acidic amino acids, keto acids and aromatic carboxylic acids, m is an integer number comprised between 1 and 22, n is comprised between 2 and 20.

Compositions, kits, and methods for repairing bonds, for example, disulfide bonds, in hair or on the skin are disclosed. The compositions provide improved conditioning benefit for dry hair or moisturize the skin. The compositions also provide a long lasting moisturized feel and smooth feel to the skin or hair, without feeling greasy. The compositions contain one or more compounds that covalently bind at least two thiol groups in the hair or on the skin. Use of the binding compositions prevents reversion of the repaired bonds to their free thiol state, for at least one week or one month, or more, after a single application of the composition. Improved methods of styling hair, for example permanent hair waving, hair curling, hair coloring or highlighting, and hair straightening, are also provided.
