      How does air pollution affect skin and hair health and appearance?

      Dr. Anet Varghese

      Doctor of Medicine (MBBS) · 1 years of exp

      Pollution breaks down collagen and oxidizes the lipid layer in the skin, which impairs skin-barrier function, resulting in dehydration, sensitivity, uneven skin tone, dullness, acne, and premature aging. Also, these particles can bind to the hair's surface, infiltrating the follicle and settling on the surface of the scalp. Severe air pollution can alter the condition of the cuticle, giving hair a rough, brittle and dull appearance.
