A genuinely effective scalp treatment. Our Salicylic Acid and Urea serum visibly removes dead skin cells and impurities that clog scalp pores and cause dandruff. Clinical-style testing showed: 97% reported a less greasy scalp and cleaner hair for longer; 97% experienced less itchiness, redness, and irritation; and 85% saw a decrease in dandruff after just 4 weeks of consistent use. A results-driven addition to the Bopi range.
