    Red Algae Extract:
    bonds to wet hair like an invisible shield to block pollutants, nourish hair, and deliver potent antioxidants to the cuticle that neutralize free radicals before they cause damage.

    Pollutants create free radicals that destroy hair bonds and proteins causing tangles, split ends, breakage, and hair that’s hard to style. Antioxidants can prevent free radical damage, but your hair doesn’t absorb most of them like your skin does.
