The first safe industrial haircolor was created in 1909 through French chemist Eugene Schuller, with all the chemical paraphenylenediamine. Hair coloring is very popular today, with over 75% of women colouring their hair and a growing percentage of men subsequent suit. How does haircolor work? It\\\'s the result of a series of chemical reactions involving the molecules in locks, pigments, as well as peroxide and ammonia, if current.

白髪染め

People have been coloring their hair for thousands of years using plants and minerals. Some of these natural brokers contain pigments (at the.g., henna, black maple shells) and others include natural bleaching brokers or cause responses that change the colour of hair (e.g., vinegar). Natural colors generally work through coating the hair shaft with color. A few natural colorants last via several shampoos, however they aren\\\'t necessarily less dangerous or more gentle than modern formulations. It\\\'s hard to get consistent results using natural colorants, and several people are allergic to the ingredients.

Temporary or semi-permanent haircolors may deposit citrus dyes onto the outside the hair shaft or perhaps may consist of tiny pigment molecules that will slip inside the hair shaft, using a small amount of peroxide or not one at all. In some cases, a collection of several colorant molecules enter the hair to form a greater complex inside the head of hair shaft. Shampooing could eventually dislodge temporary hair color. These products do not contain ammonia, meaning the hair shaft isn\\\'t exposed during processing as well as the hair\\\'s natural color is retained once the item washes out.
