This invention relates to a cosmetic composition, which controls sebum secretion of the scalp to thus create an optimal environment for hair growth and activates growth factors for promoting hair strengthening and growth, thereby improving the health of the scalp. A method of preparing the same is also provided. In the cosmetic composition, an oligopeptide functions to create an environment suitable for hair growth by controlling the sebum secretion of the scalp, and also to activate growth factors that are effective at preventing hair loss by promoting hair growth through improvement of blood circulation in the scalp and by strengthening hair through hair follicle activity, thereby improving the health of the scalp and preventing hair loss. The oligopeptide of the invention can exhibit high safety and stability of use and high absorbability into the skin and is thus excellent in improving the health of the scalp, compared to the use of existing peptide compositions.

A hair conditioner composition with a gel network, a soluble anti-dandruff active, and a preservation system. The preservation system can include an ingredient selected from the group consisting of glycol, glyceryl ester, glyceryl ethers and combinations thereof. There may be no visible crystals of the soluble anti-dandruff active in the condition composition.

Composition containing, in a cosmetically acceptable medium, one or more volatile linear alkanes, at least 0.5 wt. % of one or more aminated silicones relative to the total weight of the cosmetic composition, and one or more vegetable oils different from the volatile linear alkanes. Use thereof for the treatment of keratinous materials, preferably of keratin fibres such as the hair.

The present invention relates to a composition (F) for treating keratin fibers, notably human keratin fibers such as the hair, comprising at least one alkoxysilane of formula (I), at least one alkoxysilane of formula (II), at least one nonamino silicone of formula (III), optionally at least one coloring agent chosen from pigments, direct dyes and mixtures thereof, and optionally water.

The present disclosure relates to bleomycin for use in the treatment and/or prevention of hair loss and to a composition comprising bleomycin for use in the treatment and/or prevention of hair loss. A non-therapeutic method for promoting hair generation and/or hair growth is also disclosed, the method comprising administering or applying bleomycin or a composition comprising bleomycin to an area on the subject where the promotion of hair generation and/or hair growth is desired. Further disclosed is a non-therapeutic method for darkening hair, the method comprising administering or applying bleomycin or a composition comprising bleomycin to an area on the subject where darkening of hair is desired.

The present invention relates to a process for dyeing or bleaching keratin fibers, comprising the application to the keratin fibers of a composition comprising a high content of one or more particular amino acids followed by the application of a dyeing or bleaching composition.
