A composition for preventing thermal damage to hair containing dimethicone, reactive amodimethicone, and PPG-3 caprylyl ether. The composition helps prevent hair heat damage caused by hot air tools like hair dryers and irons. The reactive amodimethicone enhances the heat-blocking power of dimethicone. The PPG-3 caprylyl ether accelerates hair coating and adsorption of the silicones to effectively block heat penetration.

Non-aqueous hair cosmetic containing an ultraviolet absorber that provides UV protection to hair without clouding when stored at low temperatures. The cosmetic formulation contains an ultraviolet absorber, alkyl benzoate or 2-ethylhexyl isononanoate, and volatile cyclic silicone. The cyclic silicone improves low temperature stability while the alkyl benzoate prevents hair bundling during drying. The cosmetic is applied to wet hair and air-dried without rinsing.

Hair cosmetic that protects hair from UV damage and has improved usability compared to existing UV-protecting hair products. The hair cosmetic contains specific blends of water-soluble UV absorbers, cellulose, sugar alcohol, and silicone. The blends provide UV protection, enhance hair texture, and prevent fading of dyed hair. The cosmetic also contains optional components like polyoxyethylene alkyl ether. Applying and washing the cosmetic multiple times maintains UV protection.

Hair cosmetics that protect hair from UV damage and prevent fading of dyed hair. The cosmetics contain specific UV absorbers and a cationic surfactant. The UV absorbers are ethylhexyl methoxycinnamate (ethylhexyl dimethyl PABA) and hexyl diethylaminohydroxybenzoyl benzoate. The cationic surfactant improves adsorption and retention of the UV absorbers on hair. The recommended blending ranges are 0.5-20% ethylhexyl methoxycinnamate, 0.1-5% hexyl diethylaminohydroxybenzoyl benzoate, and 0.1-6% cationic surfactant.

Hair care agents that combine improved hair care properties, like combability, softness, and shine, with UV filter stability. The agents contain UV filters, like cinnamic acid esters and benzimidazole derivatives, in combination with cationic care substances. The UV filters can have cationic groups. Other care substances like vitamins, flavonoids, and silicones are also included. The agents provide enhanced hair care benefits compared to just UV filters or care substances alone.

Using copolymers of unsaturated esters and styrene sulfonates to improve thermal protection of hair during styling. The copolymers, made by copolymerizing unsaturated esters derived from alcohols and carboxylic acids with styrene sulfonate, provide better thermal protection for hair compared to conventional polymers like sodium polystyrene sulfonate. Applying these copolymers as a pre-treatment before heat styling reduces damage to the hair from overheating and friction.

Hair protectant composition to prevent and repair damage to hair from factors like friction, heat, cutting, perming, bleaching, dyeing, UV exposure, and chemicals. The composition contains charcoal as an active ingredient that shields hair from damage and helps restore it. This protects hair from external factors like UV rays, staining, discoloration, and permanent treatments while repairing damage.

Hair spray composition that minimizes UV damage to hair and prevents clogging of pump spray dispensers while providing long-lasting hold. The hair spray contains a specific copolymer with an ultraviolet absorbent monomer unit to protect hair from UV rays. The copolymer also has (meth)acrylate units for film strength, carboxyl groups for hydrophilicity, and siloxane groups for flexibility. This balance of monomers prevents stickiness and tangling. The copolymer composition can be prepared by solution polymerization using a solvent like methanol.

Using derivatives of heterocyclic carboxylic acids in hair cleansing and treatment compositions to protect hair from heat damage, regulate moisture content, increase shine, reduce breakage, and enhance resistance. The compounds are general formula (I) or (II): (I) H2N-C6H4-CO2-R1-R2; (II) H2N-C6H4-C6H4-CO2H, where R1 and R2 are alkyl groups. These compounds can be used alone or in combination with other hair care ingredients.

Hair cosmetic composition that provides good styling performance, familiarity, cohesion, and heat protection for hair. The composition contains a specific sodium polyacrylate with a molecular weight of 3.5-7 million, along with liquid oils, surfactants, and other ingredients. The sodium polyacrylate provides spreading and cohesion benefits. The liquid oils enhance spreadability and styling. The surfactants aid in spreading and styling. The composition also prevents hair damage from heat styling tools like dryers.

A hair cosmetic composition that provides long-lasting moisture and flexibility without being affected by external factors like temperature, humidity, and UV rays. The composition contains a hydrogen-bondable substance that binds to the inner cortex of the hair via hydrogen bonding. This protects and moisturizes the hair from within, similar to the effect of water. The hydrogen bonding stabilizes the moisture level inside the hair and prevents evaporation, unlike conventional moisturizers that only retain moisture temporarily.

Hair treatment products that protect hair from damage during heat styling and from environmental influences while also protecting other product components from oxidation and degradation. The products contain a mixture of water-soluble procyanidins, like oligomeric procyanidins from grape seed extract, and oil-soluble free tocopherols, like vitamin E. The procyanidins stabilize the tocopherols in water, and the tocopherols stabilize the procyanidins. This synergistic stabilization allows using both antioxidants in an aqueous hair product formulation. The product provides hair protection during heat styling by preventing oxidative damage from activated oxygen in water films on the hair surface. It also protects the hair from environmental influences. The stabilized antioxidant mixture prevents degradation of other product components like essential o

Hair spray composition that provides a natural finish and long-lasting UV protection. The composition contains a polyaspartic acid derivative to naturally finish the hair and an UV absorber to prevent UV damage. The polyaspartic acid derivative provides a natural texture and slipperiness when blended in an amount of 0.1-10% by weight. The UV absorber prevents UV damage to the hair when blended in an amount of 0.1-10% by weight.

Liposomal UV absorbers to protect hair from sun damage. The compounds have a hydrophilic head group, spacer, UV chromophore, and hydrophobic tail. They self-assemble into bimolecular layers in water. These liposomal UV absorbers have better substantivity to hair compared to traditional UV absorbers. They provide effective UV protection while preventing washing off. The liposomes protect hair from UV-induced damage like discoloration, dryness, and roughness.
