Disclosed are compositions for dyeing keratin fibers comprising at least one direct dye and/or an oxidative dye and optionally an activator, and also comprising a compound formed by esterification of phosphoric acid with isooctanol (2-ethylhexanol) and ethoxylated tridecylic alcohol.

Disclosed is a hair colouring method which comprises application to the hair of at least one dye of formula I and/or II combined with a coupler of formula III:

##STR00001## wherein R1-R6 and X are as defined in the description.

Method for simultaneously and permanently reshaping and coloring keratin fibers, particularly human hairs, in a single process in which the keratinic fibers are first waved by means of a foam-type waving agent (M1) and then lightened or colored by means of a foam-type coloring agent (M2). The permanent wave is simultaneously fixed by the oxidizing agent included in the oxidative dyeing agent. The method according to the invention brings about a uniform waving and coloring result and causes little or no damage to the hair.

A film coating for keratin fibers is described. The film coating is produced by applying to the keratin fibers a pretreatment composition and a film forming composition and curing the compositions to produce the film coating. The coating may be clear and function as a styling, conditioning and holding. The coating alternatively may contain pigment particles and provide a color coating.

The disclosure relates to compositions for treating keratinous substrates, such as the hair, comprising monoethanolamine and at least one carboxylic acid, as well as systems and methods for treating keratinous substrates with the compositions.

A hair dye that is safe for human bodies and has a high hair dyeing effect is provided. The hair dye consisting of: a reaction solution (A) comprising: a substance having a specific flavonoid skeleton represented by the following general formula (1); one type or two or more types selected from benzyl alcohol, vanillin, propylene carbonate, and γ-butyrolactone; and one type or two or more types selected from a thioglycolic acid salt, a thiolactic acid salt, cysteine and cysteamine, and a reaction solution (B) comprising an oxidizing agent. ##STR00001##
(In the formula, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.6, and R.sub.7 independently represent a hydrogen atom, a hydroxy group, or a methyl group; either one or both of R.sub.6 and R.sub.7 is/are a hydroxy group; R.sub.5 represents a hydrogen atom, a hydroxy group, a galloyl group, or a saccharide; and X represents >CH.sub.2, >C═O, or >CHOH.)

The present invention relates to a process for coloring keratin fibers, preferably hair, comprising the steps of: (i) applying onto the keratin fibers a composition comprising (a) at least one compound chosen from alkylaminosulfonic acids and those of the formula (I) and (II), (b) at least one direct dye, and (c) at least one alkaline agent; (ii) heating the keratin fibers; and (iii) optionally rinsing and/or drying the keratin fibers. The present invention can provide superior coloring efficiency, such as color intensity and color lastingness.

The present disclosure relates to a portion unit with at least one cosmetic product for oxidative color change of keratinous fibers, in particular human hair, filled receiving chamber, which is formed by a water-soluble envelope made of a water-soluble nonwoven fabric. Another object of the present disclosure is a method for oxidative dyeing of keratinous fibers, in particular human hair, using the portion unit.

The present disclosure relates to a portion unit having at least one receiving chamber filled with a cosmetic agent for lightening keratinous fibers, in particular human hair, which receiving chamber is formed by a water-soluble envelope made of a water-soluble nonwoven fabric.

Hair dye composition and method of dyeing hair that targets only at least one grey part using a permanent hair dye component comprising a specific volume percentage of a particulate pigment to permanent hair dye component. The purpose of some embodiments of the invention is to delay the need for women to dye their hair in full. At least one pigment particle (about 0.0770 ml or about 1/64th of a teaspoon) may be added to a bottle of 71 ml of permanent hair dye, which allows the permanent hair dye composition to become visible and allows for more accuracy during application. Using small quantities of 5 cc per application (hair dye: 2.5 ml; developer: 2.5 ml) reduces the amount of dye applied to needless areas of the hair. The use of a make-up sponge stick allows for better accuracy. The composition is multi-use, and provides for 28 applications (71 ml bottle of dye and 71 ml of developer), and will save users time and money. All these characteristics provide for a hair dye composition that significantly reduces the amount of harmful chemicals applied to users' hair.
