The practice of changing hair color has been on trend from the past two decades. Reasons for coloring may differ from different age groups. Some may want to hide those grey lines of age that is easily spotted while some may want to experiment with new looks and appear attractive to the outer world. According to a new research, dying hair has become as easy as going to the library. The Max Weaver Dye Library of North Carolina reports of having more than 100,000 unique dyes that are still left untouched and without any experimentation.
Scientists from State College of Textiles and Department of Chemistry hunted down the library in search of compounds having high chemical similarity to that of acquainted hair dyes. A computer based research was made to measure the similarity between chemicals in order to examine about more than 2,100 digital library dyes. Scientists found a sub-division of sets of almost about 158 compounds and each of them had high chemical properties as per hair dyes are concerned. Out of the many dye samples, amongst which one has the potential of having a stronger bond with hair.
Bye-Bye Skin Infections, Hello Nature Friendly Dyes
Since hair color has become the most lucrative business that keeps on growing rapidly, the variations in hair dyes like semi-permanent, permanent and temporary that draws more people to experiment with their hair, thus, increasing more revenue in the overall market. The hair dye types are basically classified on the basis of their longevity. The temporary hair dyes wash out with just one or two shampoos as they only coat the outer surface. The semi-permanent dyes are to last for longer period of time and the natural color of the hair comes back with around six to eight washings. Permanent hair dyes does not wash off as it gets physically trapped in the hair shaft with the help of the chemical process called oxidation.
The main aim of the test was to discover more nature and skin friendly hair dyes where there are less chances of skin-sensitive issues and allergies. The scientists are aiming to design hair dyes of novel precursors so as to take care that the environment is also safe. The unique compound structures of the dyes can be transformed into colors after it is applied on the hair.
