Provided are indigo darkener, containing: in parts by weight, 0.1-99 of indigo dye, 0-99 of alkaline dyeing assistant, 0.01-99 of acidic dyeing assistant, and 0-99 of oxidizing agent, and hair dyeing process using the indigo darkener. The multi-layer scales on the surface of hair are opened at large angles under alkaline condition and/or high-temperature condition, so that large indigo dyeing particles are easily absorbed in the scales; black indigo oxocarbon or carbon black is generated under the action of alkaline dyeing assistant and oxidizing agent at high temperature by the property that the indigo dye is easy to oxidize; the acidic dye assistant is added as the temperature decreases, and the scales having opening angles on the surface of hair are closed under acidic condition, so that the indigo carbide is firmly clamped and fixed in the scales of hair; finally, the blue indigo dyes white hair into black.

Processes and a multi-component packaging unit (kit-of-parts) are provided for decolorizing keratinous material which has been colored by the application of at least one pigment. A process includes applying to the keratinous material a decolorizing agent comprising at least one anionic surfactant, and having a pH value of 1.0 to 3.5, and rinsing the decolorization agent from the keratinous material after a contact time.

A composition for strengthening skin barrier or improving skin barrier function is able to improve objective indicators related to the protection of skin barrier, the strengthening of skin barrier, and/or the improvement of skin barrier function. The composition exhibits the effects of increasing the amount of ceramides, dihydroceramides and sphingoid bases, increasing the activities of enzymes that are involved in the synthesis thereof, and decreasing the activities of enzymes that are involved in the degradation thereof. In addition, the composition is able to restore skin barrier function by reducing TSLP, IL-4, and IL-13 which are closely associated with skin barrier damage, and thus interrupting a vicious circle in which the lipids and proteins contributing to skin barrier decrease.

Selected peptides have been found to repair, by means of nucleotide excision repair (NER), cellular DNA damaged by the exposure to external agents, in particular UV rays and are useful for cosmetic or pharmaceutical use thereof in skin treatment. Compositions for topical application that contain such peptides, preferably carried in liposomes, prevent and treat skin damage caused by the exposure to UV rays, including in subjects affected by xeroderma pigmentosum.

The present invention relates to preventing color transfer and sticking of powder-containing cosmetics to clothes or the like. A coating formation method of the present invention includes an electrostatic spraying step of electrostatically spraying a composition directly onto a skin surface onto which powder-containing cosmetics have been applied, thereby forming a coating on the skin. The composition contains a component (a) and a component (b) below. It is preferable that the method further includes a liquid agent applying step of applying a liquid agent containing one or more selected from water and oils that are in liquid form at 20° C. on the skin onto which the powder-containing cosmetics have been applied, wherein the liquid agent applying step is performed subsequent to the electrostatic spraying step. (a) One or more volatile substances selected from water, alcohols, and ketones; and (b) a polymer having a coating formation ability.

A multi-agent type hair treatment agent comprising a first composition containing component (A) and component (B); and a second composition containing component (C), wherein the weight ratio (H)/(C) of component (H) to component (C) in the second composition is less than 1. A hair treatment method comprising the steps of applying and rinsing the first composition to hair (i) and then applying the second composition to hair (ii). Component (A): a carboxylic acid having an inorganic value of 230 or more and 450 or less and an organic value of 50 or more and 250 or less, or a salt of the carboxylic acid Component (B): anionic surfactant Component (C): an aromatic sulfonic acid having a molecular weight of 300 or less or a salt thereof Component (H): cationic surfactant.

A combination product comprising a dispensing head (10, 10′) mounted on a top of a container (20, 20′) containing a formulation for nasal administration, and a solidified skin-care balm (50) for application around the nose contained in a balm holder element (30, 30″) located on a bottom (24) of the container (20).

Disclosed is a transfer-resistant and long-lasting two-step cosmetic system, and a method for applying the cosmetic system. The disclosed system includes a first composition that includes a styrenic block copolymer, a silicone acrylate copolymer, and a volatile oil and a second composition that includes a silicone oil.

Removable hair coloring compositions are described herein that include: at least one hair color composition or compound; and at least one sealing component or compound, wherein at least one of the at least one hair color composition or compound, or the at least one sealing component or compound can be physically dissolved, physically removed, or a combination thereof when mixed with at least one natural oil. In some embodiments, removable hair coloring compositions further include at least one preparation stage component or compound.

A method to produce an effective cool tone with blonde hair color, while performing the hair dyeing process. To that end, the desired blonde hair color may be achieved by incorporating pigmented capsules and/or any pigmentation agent into the hair bleach mixture and/or the hair peroxide mixture. The pigmentation agent provides a cool tone effect while simultaneously removing unwanted yellow and orange undertones from hair during the hair bleaching process. Accordingly, the method includes producing pigmented hair bleach mixture and pigmented hair peroxide mixtures for performing the hair lightening process. However, it is important to note the scope of the method includes incorporation of pigmented capsules and/or any pigmentation agent into any and all related hair dyeing or hair coloring and hair care products to achieve toning of hair.
