A biological hair shape change composition including a macromolecular component, a small molecular component and an alkali agent component is provided. The macromolecular component includes a protease belonging to the class of alkaline proteases, and the small molecular component includes a peptide with reduction activity. Both the macromolecular component and the small molecular component are obtained from a fermentation product of Bacillus licheniformis and a keratin and/or keratin polymer-containing medium. Molecular weights of ingredients in the macromolecular component are greater than or equal to 3 kDa and are 3-1000 kDa, and molecular weights of ingredients in the small molecular component are less than 3 kDa and are 0.01-2.99 kDa.

A soothing lip balm composition includes a wax binder component, which includes at least two compounds selected from a C.sub.8-C.sub.30 fatty acid, esterified C.sub.8-C.sub.30 fatty acid, and C.sub.8-C.sub.30 fatty alcohols; a complex fat component, which includes at least three different compounds selected from C.sub.8-C.sub.30 fatty acids; an organic compound component, which includes at least three compounds selected from 2,5-dimethoxy-p-cymene, cumene, thymol methyl ether, 2,6-diisopropylanisole, decanal, and 1,2,2,3-tetramethylcyclopent-3-enol; and an enzymatic component, which includes cysteine endopeptidase.

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 non-therapeutic cosmetic treatment method includes at least: —applying an active composition including at least niacinamide onto the skin of a subject, and—illuminating the skin using at least one light source emitting at a wavelength of between 620 and 690 nanometres, preferably 660 nanometres, the illumination being carried out before, at the same time as or after the application of the composition. A device is configured for implementing such a method.
