Hair changes as we age, getting finer, drier, and less shiny than it used to be. Chronologiste Bain Régénérant is Kérastase's regenerating shampoo made specifically for aging hair, using abyssine, hyaluronic acid, and vitamin E to hydrate the scalp, replenish the fibre, and bring softness, strength, and shine back from the very first wash.

The 500ml size is for regulars, longer or thicker hair that goes through shampoo faster, households sharing between more than one person, or anyone who'd rather stock up on the shampoo they already know works.

• Apply a coin-sized amount to damp hair.
• Emulsify through the hair, starting from the roots down to the lengths and ends.
• Massage using gentle pressure.
• Rinse thoroughly. 
• Repeat.
