“…Semi-permanent hair dye products have higher wash resistance than temporary dyes because the semi-permanent dye molecules are in a form that can be applied with other oxygen-release agents without hydrogen peroxide or alkali solution. Robbins and Crawford only examined the diffusion pattern of semi-permanent color and found that weak Van der Waals bonds are formed in the semi-permanent coloring mechanism [29].…”

One of the oldest and most well-known cosmetics, hair color has been used by numerous ancient cultures throughout history on both men and women. It involves treating hair with various chemical compounds for changing hair color. According to how long they remain in the hair, these products are primarily divided into two categories: temporary and permanent. This classification is consistent with the types of active substances used in the dyeing process as well as the dyeing method itself, which are referred to as non-oxidative and oxidative hair dye products, respectively. Permanent hair dyes often consist of active chemicals that are not dyed but are oxidized to provide the desired color. As a result, the phrase "oxidative hair dye" was emerged. The precursor part and coupler part are the two main ingredients in formulations for oxidative hair dyes. Quinonediimine intermediates are momentary compounds that are generated when combined with hydrogen peroxide (developer). As a result, the coupler agent and these compounds interact to form the appropriate hair dye molecule. Notably, the entire dyeing process requires both an alkaline medium and an oxidizing agent, often hydrogen peroxide, to ensure that the staining agents reach the cuticle widely. This review's objective is to provide information about hair dye formulations and mechanisms of action as well as repairing damaged hair and new applications.

Hair dyes have been used to cover gray hair or to give an appealing look. In the present study, the extract of Calendula Officinalis was used in preparing a hair dye. This represents a natural gateway in development of hair dye to avoid damage caused by synthetic dyes. The yellow coloring principle of the extract, Calendulin, was converted into nano-sized formula ensuring hair fiber penetration. Nine formulae were prepared by solvent evaporation technique, based on a 32 factorial design using Design Expert® program, independent variables being: speed and time of homogenization; three levels: low, medium and high. Polyvinyl alcohol (0.5% w/v) was used as stabilizing agent. Formulae were evaluated by determination of Zeta size, potential and polydispersity index. Response surface modeling enabled choosing the optimal formula (least particle size, polydispersity index and highest zeta potential), which was evaluated by transmission electron microscopy and dyeing effect as a gel containing 0.5% Carboxymethyl cellulose. F7, produced by operating the homogenizer at 26000rpm for 10 minutes proved to be optimal which succeeded to dye white hair and lighten up the black hair as evidenced by optical microscope images. Hence it was recommended to use F7 in covering the white hair.
