A purifying cleanser that gently exfoliates and eliminates excess oil and flakes caused by dryness to help improve overall scalp condition and promote a longer-lasting blowout. Great for dry, oily, or sensitive scalps. Features Drybar's scalp-friendly Noir scent with notes of ginger, mint, and sandalwood. The scalp massaging applicator helps support circulation and remove impurities. The cooling sensation offers an instant feeling of relief. A gentle scalp-friendly scent will not disrupt the scalp's natural microbiome. When used as a pre-shampoo before a Drybar shampoo and conditioner, Crown Tonic extended the need to wash hair again for up to 4 days (based on a third-party clinical study). Key Ingredients: Probiotic Complex, derived from Lactic and Amino Acids, targets flakes caused by dryness, soothes discomfort, and helps to lock in hydration for up to 24 hours (clinically tested). AHA/BHA Complex, with Glycolic Acid and Salicylic Acid, helps to gently exfoliate and remove build-up. Mango Leaf Extract, a natural oil-controlling active, helps balance excess sebum. Made without parabens and phthalates. Sulfate-free, Keratin-free, gluten-free, honey-free, nut-free and it's vegan, too! How to Use: For use on wet hair. Twist the nozzle to open and squeeze a generous dollop directly onto the scalp. Twist the nozzle to close, then massage gently and rinse well. Follow with your favorite Drybar shampoo and conditioner. Use with every wash or as needed to help rebalance and soothe the scalp. After use, be sure to twist the cap closed to avoid prematurely dispensing cleanser and keep the scalp-massaging applicator clean and dry.
