Development of a Classification System for Extrinsic Hair Damage: Standard Grading of Electron Microscopic Findings of Damaged Hairs
TLDR Researchers created a standard system to grade hair damage using microscopic images.
The study aimed to create an objective classification system for extrinsic hair damage using electron microscopy (EM). Researchers analyzed over 2000 scanning and transmission electron microscopic images of both normal and damaged hairs. They identified the need for standardized terminology and descriptions, as previous studies used varying and subjective terms. The result was the development of a standard grading system for damaged hairs, which was intended to be easy, objective, and useful for assessing hair damage and the efficacy of hair care products.
