Zerran Oily Hair Dandruff Shampoo is a sulfate-free and fragrance-free shampoo that uses botanical science instead of harsh chemicals to reduce oiliness, flakiness and itching associated with oily hair dandruff. The coffee and tea tree extracts help fight free radicals, and other natural essences soothe the scalp. The sulfate-free and paraben-free formula is scented by natural tea tree oil and eucalyptus oil with no added artificial fragrances.
