Shea Moisture Jamaican Black Castor Oil Strengthen, Grow & Restore Shampoo is a purifying, sulfate-free shampoo that removes product buildup, hydrates, and adds shine. Gentle enough for daily use, it promotes hair growth, nourishes, and strengthens damaged, dry, and chemically treated hair. It also reduces breakage. Apple cider vinegar helps regulate and balance the scalp's pH, softening hair and promoting healthy growth.
