Chronologiste Bain Régénérant Shampoo
A luxurious hydrating and volumizing shampoo designed for aging hair that needs softness, bounce, strength, and shine.
A premium shampoo for people who want a fuller, softer, more revived-looking finish while still cleansing gently.
People who invest in anti-aging skincare want the same formulation intentionality applied to their hair. The Chronologiste lineup is the most direct answer the professional haircare world has to that demand. The Bain Régénérant shampoo is the accessible entry point into that system.
First step of wash day — apply to wet hair before the Chronologiste conditioner or mask, and before any leave-in treatments like the Overnight Youth Serum.
People who have noticed their hair has changed with age — less body, less bounce, less shine — and want a shampoo that actively works against those signs rather than just cleansing and rinsing.
Very oily scalps that need strong purifying cleansing — this is a softening and hydrating shampoo, not a clarifying one. For oily scalp imbalance, the Spécifique Bain Divalent is a more appropriate choice.
If scalp feels coated or heavy after washing, it may be too rich for your scalp type. Consider alternating with a lighter shampoo on mid-week washes.
- The Chronologiste Hair Mask for a deeper weekly treatment on dry, aging lengths
- The Chronologiste Overnight Youth Serum as a leave-in after washing for full age-support coverage
- The Genesis Serum Fortifiant applied to the scalp after washing if breakage is also a concern
Best For
- Aging hair
- Dull hair
- Hair lacking volume
- Hydration and softness
- Luxury anti-aging hair routines
How to Use
Apply to wet hair, massage into the scalp and lengths, lather well, then rinse thoroughly. Follow with Chronologiste conditioner or mask.
Key Ingredients
Draws water to the skin and helps lock it in, making skin appear plumper, smoother, and more hydrated.
Abyssine is primarily known for its soothing and skin-sensitization-reducing properties — clinical studies have shown it can help reduce skin reactivity and calm irritation-related redness. In haircare, it functions as a conditioning and soothing active, supporting the scalp environment and hair fibre softness. It is particularly used in prestige and anti-aging formulations where premium marine ingredients are part of the formulation story. In the Kérastase Chronologiste line, it contributes to the luxury anti-aging haircare narrative alongside Hyaluronic Acid and Vitamin E.
Vitamin E neutralizes free radicals in the skin's lipid layers, supports barrier function, helps reduce transepidermal water loss, and works synergistically with vitamin C — with ferulic acid further amplifying this combination. In formulations, it also stabilizes other active ingredients and extends shelf life.
Fragrance has no skincare function — it is added purely for sensory appeal and brand experience. Some fragrant ingredients (like linalool, limonene, and eugenol) are known sensitizers that can cause contact dermatitis in sensitive individuals over repeated exposure.

About This Product
The Kérastase Chronologiste Bain Régénérant is the cleansing foundation of the Chronologiste age-support haircare system. "Bain" is the French word for "bath" — Kérastase uses this naming convention for shampoos across their lineup — and "Régénérant" signals the regenerating or revitalizing intent. The formula is designed around aging hair's specific needs: not just dryness, but the loss of volume, bounce, and structural integrity that comes with hair that has been colour-processed, heat-styled, and exposed to environmental stressors for years. Key actives include Abyssine (a marine-sourced amino acid complex originally developed for skincare, known for soothing and conditioning), Hyaluronic Acid (for hydration support), and Vitamin E (for antioxidant support). Together these actives form a premium anti-aging shampoo formula that positions the wash step itself as a first layer of treatment rather than a simple cleanser. The result is hair that feels visibly softer, fuller, and more revived from the very first step of the shower routine.
