KÉRASTASE Balancing Shampoo for Oily Scalp & Dry Ends — 8.5 fl oz, Hydrating, Volumizing

KÉRASTASE Bain Divalent is a balancing shampoo that gently removes excess oil from the scalp while hydrating lengths and ends for soft, voluminous hair.

This lightweight shampoo is formulated to tackle two common hair concerns at once: oiliness at the scalp and dryness along the lengths. It cleanses impurities and sebum buildup without stripping the fiber, and leaves hair feeling cleaner at the roots and more nourished toward the ends. The formula combines amino acids, ceramides, and vitamin B6 to support fiber integrity and help hair look fuller after use.

How does this shampoo control oily roots without drying hair ends?

Bain Divalent uses a delicate cleansing base to lift excess oil and dirt from the scalp while deploying conditioning agents that target the mid-lengths and ends. This two-action approach prevents the common trade-off between clean roots and brittle ends. It’s designed for repeat washing and can be applied twice with emphasis on the lengths during the second lather.

• Ultra-light surfactants remove sebum and grime without harsh stripping
• Amino acids help maintain fiber balance and reinforce hair structure
• Conditioning actives and ceramides hydrate ends to reduce roughness
• Vitamin B6 adds protection against external aggressors

Will this shampoo add volume to flat, oily hair?

Yes — the formula is engineered to create lift at the roots while keeping lengths supple. By clearing away product residue and excess oil, the scalp regains natural buoyancy and hair appears fuller. Many users notice increased volume after regular use.

• Removes buildup that weighs hair down at the scalp
• Light conditioning avoids flattening the roots
• Strengthening amino acids reduce fiber fatigue for better body

How should I use Bain Divalent for best results?

Apply to thoroughly wet hair and massage into the scalp to dissolve excess oil, then rinse. For a deeper clean, repeat and concentrate the second application on lengths and ends. Rinse fully and follow with a targeted mask or serum from the Specifique range if you want more hydration or long-term rebalancing.

• Wet hair completely before shampooing
• First pass: focus on the scalp to remove oil
• Second pass: emulsify and concentrate on lengths and ends
• Pair with Potentialiste Serum or Masque Rehydrant for stronger results

Are there active ingredients I should know about?

The formula highlights amino acids, ceramides, and vitamin B6 to cleanse gently while supporting hair structure. Amino acids help maintain the hair fiber’s balance; ceramides reinforce the cuticle and reduce frizz; vitamin B6 contributes to protection against environmental stressors. Together they work to refresh the scalp and nourish the hair without excess heaviness.

• Amino acids: balance and reinforce hair fiber
• Ceramides: strengthen cuticle and smooth lengths
• Vitamin B6: adds antioxidant support and protection
• Dermatologically tested formula for scalp safety

Who this is for: KÉRASTASE Bain Divalent is suited to people with oily scalps and dry or fragile ends who want a single shampoo to address both concerns. It benefits those who wash their hair regularly and need a cleansing product that restores root volume while preserving hydration along the lengths. If your routine includes treatment serums or masks, this shampoo pairs well with the Specifique line to optimize rebalancing and long-term hair health.
