Hair Dye

Dyes are formulated to give hair long-lasting and richly hued colors, but several factors — from mechanical to environmental — can accelerate color changes and fading.

New understandings in genetics and biology and the role of DNA in dictating the color, condition and health of hair are taking hair-coloring technology into a whole new realm.

Scientists are looking into hair-coloring techniques of the future, including nano-sized colorants and substances that stimulate the genes to produce melanin pigment that colors hair.
