The invention relates to a process for the cosmetic treatment of keratin fibres, in particular human keratin fibres such as the hair, implementing the application of a composition comprising at least one surfactant, and the application of a composition comprising a particular metal compound and a conditioning agent chosen from cationic surfactants and/or fatty alcohols.

Compositions and methods are disclosed for repairing split ends in hair and/or micro-damage to hair shafts. The compositions comprise a variety of oils, optionally including meadowfoam seed oil (Limnanthes alba seed oil), abyssinian oil (Crambe abyssinica seed oil), and camellia seed oil (Camellia oleifera seed oil). The compositions for repair of split ends and/or micro-damage to hair shafts may be encapsulated in microcapsules. The disclosed compositions and methods can completely repair split ends 3 mm long and under, within one-minute following application.

The present application relates to a composition comprising, notably in a physiologically acceptable medium: a. water; and b. at least one cationic polymer (PC) chosen from methyldiallylamine polymers or diallyldimethylammonium polymers; and c. at least one anionic polymer (PA) chosen from methacrylic acid homopolymer salts; and d. at least one anionic surfactant comprising at least one cationic counterion; and e. a fatty phase; and f. at least one pigment; the weight ratio of the total amount of cationic polymer(s)/the sum of the total amount of cationic polymer(s) and of the total amount of anionic polymer(s) ranging from 40% to 70%; the weight ratio of the sum of the total amount of cationic polymer(s) and of the total amount of anionic polymer(s) to the sum of the total amount of anionic and cationic polymers and of the amount of water ranging from 5% to 25%. The invention also relates to a process for coating keratin materials, in particular the skin, notably the contour of the eyes, eyelashes or eyebrows, and keratin fibers, such as the eyelashes and/or the eyebrows, comprising a step of applying to said keratin materials at least one composition as defined above.

The present invention relates to a cosmetic composition comprising: from 30% to 89% by weight of at least one polar oil with respect to the total weight of the composition; from 6% to 45% by weight of at least one C.sub.2-C.sub.6 aliphatic monoalcohol with respect to the total weight of the composition; from 4% to 30% by weight of hexylene glycol with respect to the total weight of the composition; from 8% to 40% by weight of dipropylene glycol with respect to the total weight of the composition; and at least one hydrophilic active agent, said composition containing less than 15% by weight of water with respect to the total weight of the composition.

A method for strengthening and repairing keratin fibres including providing a caustic as well as an acidic crosslinking composition, wherein the caustic crosslinking composition comprises an at least bi-functional Brønsted-base and the acidic crosslinking composition comprises an at least bi-functional organic acid, and a cosmetically acceptable carrier; applying the caustic as well as the acidic crosslinking composition to keratin fibres; and optionally mixing the caustic crosslinking composition into a commercially available hair colouring or hair bleaching composition.

Described herein is a shampoo composition and methods of using the same, the shampoo composition including a copper chelant, a detersive surfactant, and a carrier.

Described herein is a hair conditioner composition and methods of using the same, the hair conditioner composition including an effective chelant. The hair conditioner composition further includes one or more high melting point fatty compounds and a cationic surfactant.

Hair cleansing conditioners which include—in relation to the weight of the total composition— a) from about 0.0001 to about 10 wt. % of a cationic 3-acrylamidopropyl trimethylammonium salt homopolymer, and b) from about 0.01 to about 20 wt. % of at least one non-ionic surfactant and/or at least one amphoteric surfactant
are exemplified by an excellent cleansing and conditioning effect. Hair treated with the hair cleansing conditioners has volume and fullness even after repeated use. There is no weighing-down of the hair (no build-up effect). In addition, treated hair has an improved feel and improved styling properties and improved combability. Such hair cleansing conditioners can also be easily rinsed out from the hair.

The present invention relates to a pretreatment composition of a process for dyeing or bleaching keratin fibers, comprising at least 5% by weight of one or more particular amino acids and at least 5% by weight of one or more monoalcohols, and alsoto a dyeing or bleaching process using the pretreatment composition.

The invention refers to a decomposed platelet concentrate containing ≤50% intact platelets and optionally ≥200 pg/ml RANTES and specifically to its use in the prevention or treatment of hair loss and/or for promoting hair growth. The invention further refers to a composition comprising the decomposed platelet concentrate and body fat cells and the use of said composition for reconstructive and aesthetic and curative surgery and pain relief treatment.
