The present invention relates to a cosmetic composition comprising a) one or more polyhydroxyalkanoate (PH A) copolymers which contain, and preferably consist of, at least two different repeating polymer units chosen from the units (A) and (B) below, and also the optical or geometrical isomers thereof, the organic or mineral acid or base salts thereof, and the solvates thereof such as hydrates: -[-0-CH(R.sup.1)—CH.sub.2—C(0)-]- unit (A) -[-0-CH(R.sup.2)—CH.sub.2—C(0)-]- unit (B) in which polymer units (A) and (B): —R.sup.1 represents a hydrocarbon-based chain chosen from i) linear or branched (C.sub.5-C.sub.28)alkyl, ii) linear or branched (C.sub.6-C.sub.28)alkenyl, iii) linear or branched (C.sub.6-C.sub.28)alkynyl; preferably, the hydrocarbon-based group is linear; said hydrocarbon-based chain being optionally substituted and/or interrupted with atoms or groups as described in the description; —R.sup.2 represents a cyclic or non-cyclic, linear or branched, saturated or unsaturated hydrocarbon-based group, comprising from 3 to 30 carbon atoms; b) a fatty medium comprising one or more fatty substances which are preferably liquid at 25° C. and at atmospheric pressure; it being understood that (A) is different from (B).

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.

A cosmetic composition exerts a high improving effect on a texture of hair of a head or a scalp. The cosmetic composition includes nucleic acid, succinic acid, alanine, citric acid, and glycine. An amount of the nucleic acid is 6.6 to 11.5% by mass based on a total mass of the composition, and an amount of the citric acid is 7.1 to 17.4% by mass based on the total mass of the composition. The cosmetic composition is allowed to contain at least one member selected from, for example, histidine, arginine, proline, isoleucine, serine, valine, aspartic acid, threonine, phenylalanine, pyrrolidonecarboxylic acid, sodium pyrrolidonecarboxylate, sodium lactate, and water to prepare a cosmetic.
