A kinder way to dye

摘要

Commercial partners are being sought to upscale a scientific research project developing a nanotechnology-based hair colouring treatment that has "strong capabilities to revolutionise the cosmetics industry",academics claim.Researchers at Louisiana Tech University in the US have developed a technique to dye or treat hair without using external chemicals,which can be harmful to hair.The key to the new technique is avoiding using oxidation,which can thin and dry the hair after treatments,especially permanent dye colour precursors,which oxidise on the hair surface when combined with hydrogen peroxide.
