KÉRASTASE Bain Divalent Balancing Shampoo for Oily Scalp & Hydrated Ends 8.5 fl oz — Lightweight, Volumizing

KÉRASTASE Bain Divalent is a balancing shampoo that cleans excess oil at the scalp while nourishing mid-lengths and ends for softer, shinier hair.

This lightweight cleanser is formulated to address two common hair concerns at once: oily roots and dehydrated lengths. Using amino acids, ceramides and vitamin B6, the formula targets excess sebum at the scalp without stripping the strands, then deposits gentle conditioning agents down the shaft to smooth and add shine. The result is a cleaner scalp, added root volume and softer ends that feel manageable after rinsing.

How does this shampoo remove oil without drying the ends?

The balanced surfactant system is designed to lift sebum from the scalp while preserving moisture in the hair fiber. Amino acids help maintain the hair’s natural structure, and ceramides reinforce the lengths so they don’t become brittle after cleansing.

• Gentle cleansing agents remove sebum and impurities at the root.
• Amino acids support hair fiber integrity to avoid over-drying.
• Ceramides and conditioning agents hydrate mid-lengths and ends.
• Vitamin B6 provides ongoing protection against environmental stressors.

Will it give my hair more volume at the roots?

Yes—this formula is developed to create a lighter feel at the scalp, which helps reduce flattening and restore lift. Clinical feedback indicates many users notice improved body after use, making it a good choice for fine or limp hair with oily tendencies.

• Ultra-light texture avoids weighing down the roots.
• Removes residue that can make hair lie flat.
• Leaves a clean base for styling products to perform better.

How should I use it for best results?

Apply to thoroughly wet hair, massage into the scalp and rinse. For a deeper clean, repeat the wash concentrating the second application on the lengths and ends, then rinse. Avoid contact with eyes; if contact occurs, rinse immediately.

• First wash: focus on scalp to remove oil and impurities.
• Second wash: concentrate on mid-lengths and ends for hydration.
• Rinse thoroughly and follow with a conditioner or masque if needed.
• Pair with KÉRASTASE Potentialiste Serum or Masque Rehydratant for balanced results.

How does this fit into a scalp and hair care routine?

Bain Divalent works best as part of a targeted regimen when your scalp is oily but lengths need moisture. Use it regularly to maintain balance, and add complementary KÉRASTASE treatments to address specific scalp sensitivity or deep hydration needs.

• Use 1–3 times weekly depending on oil production and styling product use.
• Follow with a lightweight conditioner or hydrating masque on the ends.
• Combine with scalp-targeted serums for persistent oiliness or sensitivity.

Who is this for: KÉRASTASE Bain Divalent is designed for people with oily scalps and dry or damaged mid-lengths and ends who want a single cleanser to rebalance both zones. It’s especially suitable for fine to medium hair that needs root lift without sacrificing softness at the tips. If you use styling products regularly, live in an urban environment, or have alternating oily and dry areas, this shampoo provides a targeted approach to restore a fresher scalp and smoother lengths.
