5. The Active Urbanite Who Wants Pollution Defense

Your lifestyle exposes your hair and scalp to environmental stressors like pollution, hard water, and sweat, and you want a specialized product to detoxify and protect against these daily aggressors.

Scalp Feels Incredibly Light and Fresh

Users say their scalp finally 'breathes' again. The clay draws out impurities that water alone can't touch, leaving a clean, refreshed feeling that lasts for days.

Hair Has More Volume and Body

By clearing the follicles of buildup, hair can stand away from the scalp more easily. Reviewers note 'lift at the roots' and hair that 'doesn't go flat' as quickly.

Reduces Itchiness and Discomfort

A clean scalp is a calm scalp. This helps soothe the minor irritation and itch that comes from product residue and environmental pollutants, without being harsh.

Makes Hair Look Cleaner for Longer

When your scalp isn't clogged, oil distributes more evenly. Many find they can extend time between washes because their hair 'stays fresh' and doesn't get greasy as fast.

Gentle Enough for Sensitive Scalps

Formulated without common irritants, it provides a deep clean that doesn't strip or leave skin feeling tight and dry. Users with sensitivity report 'no reaction' and 'soothing' feel.

Improves Overall Hair Manageability

Hair that's clean from the root out is easier to style. People mention less frizz, smoother blow-drys, and that products 'work better' afterward.

Targets Hard Water Damage

Specifically helps remove the dulling film from mineral-heavy water. Users in areas with hard water say it brings back 'shine' and 'softness' they thought was gone.

Simple, No-Fuss Weekly Treatment

Takes just a few minutes in the shower. It's an easy addition to your routine that delivers a salon-quality detox at home, with 'no mess' from the single-use pack.

Born from Kose's Predia research labs in Tokyo, this formula was created for those whose scalps feel the weight of modern life—hard water, stress, and product buildup. Our chemists sought a solution that was both deeply effective and gentle, leading them to the mineral-rich Sea Clay from the Seto Inland Sea, known for its purity. Every sachet is produced in a Japanese GMP-certified facility, ensuring pharmaceutical-grade quality control. The result isn't just a cleansing clay; it's a targeted scalp detox protocol that has become a top-ranked hair care staple in Japan, trusted for its no-fuss, visible results.

The Kose Predia Blue Repair Head Cleansing Sea Clay Sachet - Scalp Detox is formulated with a blend of targeted ingredients designed to cleanse, detoxify, and revitalize the scalp. Key components include sea clay, which acts as a primary cleansing agent to absorb excess oil, impurities, and product buildup from the scalp and hair follicles, promoting a deep detoxifying effect. Sodium lauroyl methyl isethionate serves as a gentle, sulfate-free surfactant that creates a rich lather to remove dirt and sebum without stripping the scalp's natural moisture barrier. Glycerin is incorporated as a humectant to attract and retain hydration, helping to maintain scalp moisture balance and prevent dryness or irritation. Additional ingredients like menthol provide a cooling sensation that soothes the scalp, reduces itchiness, and enhances the overall sensory experience during use. Seaweed extract, rich in minerals and antioxidants, supports scalp health by nourishing hair follicles and potentially improving circulation for stronger, healthier hair growth. This combination works synergistically to clarify the scalp, reduce excess oil, and create an optimal environment for hair vitality, making it suitable for those seeking a refreshing, deep-cleansing treatment to address scalp concerns such as dullness or congestion.
