    TLDR Researchers created a standard system to grade hair damage using microscopic images.
    Researchers developed a standard grading system for extrinsic hair damage using over 2000 electron microscopic images of normal and damaged hairs. This system aimed to provide an objective and uniform method for assessing hair damage, addressing the limitations of previous subjective and varied descriptions. The proposed grading system utilized both scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to offer a reliable and standardized approach for evaluating hair damage and the efficacy of hair care products.
