Think of your scalp as an extension of your facial skin—in fact, scalp is the second most sensitive area on your head, just after the eye contour. It's the vital "soil" from which your hair grows, home to more than 100,000 follicles and a rich supply of nerves and blood vessels. Today, with the rising quality of life, people place a greater emphasis on skin care, with (scalp care also encompassed). Since the scalp and hair significantly influence facial and overall aesthetics, the interest in scalp wellness is surging. Consequently, finding effective ways to assess scalp health has become a pressing need.

PFAS (perfluoroalkyl and polyfluoroalkyl substances) have become a globally critical issue due to their impact on the environment and health. Due to their extreme chemical stability, they are virtually indestructible in the environment, accumulating in soil, water sources, and even human bodies for decades, earning them the nickname "forever chemicals." Commonly used in food contact materials, textiles, electronics, and daily chemical products, PFAS are often employed as waterproof and oil-resistant coatings, surfactants, or additives. Studies have linked PFAS to serious health issues such as cancer, immune system suppression, liver damage, and developmental delays in children.
