ONSENSOU Scalp Care Shampoo & Treatment

Japan's #1 scalp ritual, bottled.

The award-winning trio at the heart of ONSENSOU. Built on rare Beppu hot-spring algae and hydrolyzed yeast extract, it sweeps away excess oil and buildup and keeps the scalp balanced and comfortable — the foundation of fuller, healthier-looking hair.

The line-up:

• Scalp Care Shampoo (Menthol): a cool, refreshing deep cleanse with a rich lather, even in hard water.
• Scalp Care Shampoo (Mild): a gentle, low-stimulation wash made for sensitive scalps.
• Scalp Care Treatment: four plant oils — jojoba, argan, avocado and mango — to soften and add shine from scalp to ends. Silicone-free, so it never weighs roots down.

Best for: oily scalps and roots, fine or thinning-looking hair, sensitive scalps (choose Mild), and hair stressed by perms or color.

The ritual: Massage shampoo into a wet scalp, let it work for 30 seconds, rinse, then apply the Treatment to scalp and lengths.

Good to know: SIX-free formula — no sulfates, parabens, silicones, coal-tar dyes, petroleum surfactants or isothiazolinones. @cosme Award No.1 in scalp care · over 2 million sold.

Made in Japan. A soft floral-musk scent with tea notes.
