Evolution of temporary hair dye

Hair dyes, in addition to the commonly used permanent dyes, semi-permanent dyes, there is "a temporary dye."

General hair salon with a relatively small, but the market still holds its volume of sales, especially with some of the young age of the consumer market; hair in a way, there is use a powder, paste, spray, etc.. When a temporary hair dye, pigment particles or dye intermediates can be present in the surface of the skin layer, the composite hair dye to the plasma membrane, or layers, are known as a temporary hair dye.

Human hair natural color, from brown to black color tone of the human hair, the decision on the action of melanin granules is present in the hair cortex and medulla layer. Melanin particles are arranged according to its different chemical composition of the particles can be divided into brown eumelanin, with red, yellow pigment two kinds.

By the shape, size and number of the pigment particles in the degree of polymerization of the two combinations of the three elements together, determines the color of each of the natural hair. Temporary hair dye can brown and black hair dye for natural tones of gold, red and black colors, the product available on the market wipe, spray paint, etc..

European and American products, generally use larger molecules quality acid dyes, it can not be dyed epidermis, only attached to the surface of the epidermis, it has not hydrogen peroxide, hydrogen peroxide into because it does not depend on the color or fade. In addition, the use of cationic dyes, the dye being used to promote skin permeation and cortical layer. (Refer to the characteristics of the acidic dye)

Because the general temporary dye, can be completely washed off after the next washing hair. Japanese popular these years temporary hair Pre Bonded Nail Hair dyes are water-insoluble pigments, carbon black or a pigment treated by ultra-fine, dispersed in a polymer resin solution, the colored resin after the dispersion of polymer adsorbed on the surface of the epidermis, the degree of stability well, good texture products, are generally able to completely wash out with a shampoo. Products are spray, powder, paste type. Product key new invention, mainly in the carbon black particles and the pigment to improve the dispersibility and anti-aggregating properties, the polymer resin coating and to improve the friction of the hair and the degree of damage stability.

Whether it is a temporary or acidic dye agent, belong to the physical properties of hair, hydrogen peroxide is not used, there is no change in the oxidation combination, also free of ammonia with an alkaline material, it will not cause damage to the hair . So in response times when there is a special occasion when you want to use, you can use the entire head, you can only use a part of, with different shapes, different colors chosen to do different design, but also a very convenient approach.
