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.

The is provided a compound of formula I or II or physiologically acceptable salts or solvates, or oxidised derivatives thereof:

where R.sup.1 to R.sup.3, R.sup.13 and R.sup.14 are as defined herein. Also disclosed herein are methods of dyeing hair or (temporarily) tattooing the skin using the compounds of formula I or II (or physiologically acceptable salts or solvates, or oxidised derivatives thereof) in a suitable composition.

A one step hair color and relaxer system comprising: an alkalizing agent in the range between about 0.1% to about 8%, based upon the total concentration of the hair color and relaxer system; a hair dye; and an oxidizing agent in the range between about 0.1% to about 6%, based upon the total concentration of the hair color and relaxer system; wherein the pH of the hair color and relaxer system is in the range between about 9 to about 14.

The present disclosure relates to the field of hair coloring compositions. Described herein is an oxidative hair coloring composition including microcapsules made of a perfumed-oil based core and a polymeric shell. Also described herein are a method for coloring hair and a hair coloring kit.

The present invention relates to a composition for dyeing keratin fibers, for example human hair, with oxidative hair dyes. The composition contains as oxidative dyes a combination of a p-phenylenediamine derivative as the developer substance and 2,7-naphthalenediol as the coupler substance in a suitable base. An oxidizing agent such as hydrogen peroxide is used as an additional component for developing the dye. The invention relates to a use of the composition for gray coloration, with a long-lasting reduction of a yellow tinge in a hairstyle of gray, previously dark hair.

A cosmetic method for modulating pigmentation in a subject includes administering a modulator of angiotensin-converting enzyme 2 (ACE2 modulator) to the subject. The ACE2 modulator can be an inhibitor of angiotensin-converting enzyme 2 (ACE2 inhibitor), in which case, the ACE2 inhibitor can be administered to increase pigmentation in the subject. The ACE2 modulator can also be an activator of angiotensin-converting enzyme 2 (ACE2 activator), in which case the ACE2 activator can be administered to decrease pigmentation in the subject. The treatment of inflammatory skin disease can also be achieved by inhibition of angiotensin-converting enzyme 2.

The subject of the present disclosure is a method for coloring of human hair, comprising the following steps in the specified sequence A) Mixing a first component (K1) with a second component (K2) to produce a first mixture (M1), B) Mixing the mixture (M1) with a third component (K3) to produce a second mixture (M2), C) Application of the mixture (M2) on the hair, D) Allowing the mixture (M2) to take effect for a period of from about 30 seconds to about 45 minutes, E) Rinsing the mixture (M2) from the hair, wherein the first component (K1) is a dye preparation comprising at least one oxidation dye precursor, and the second component (K2) is a color diluent which does not contain any oxidation dye precursors or oxidants and the third component (K3) is an oxidant preparation comprising at least one oxidant.
