Use and care

After the matching System 4 Shampoo, apply conditioner from roots to ends on wet hair, distribute evenly, and rinse thoroughly. Use the sealed-bottle amount and timing. Avoid eyes, rinse with water if contact occurs, and stop if irritation develops. Keep the product linked to System 4; do not substitute directions from another numbered system or present reduced breakage as guaranteed hair regrowth.
