Best for: Blonde, bleached, lightened or highlighted hair that feels dull, dry or lacks shine and needs lightweight hydration and brightness without purple pigments.

What is Kérastase Blond Absolu Bain Lumière Shampoo?

Kérastase Blond Absolu Bain Lumière is a hydrating and illuminating shampoo designed to gently cleanse blonde, lightened and highlighted hair while helping remove pollution and dulling agents that can reduce its brightness.

The lightweight clear-gel formula leaves hair feeling hydrated without weighing it down, helping blonde hair look luminous, soft and fresh. It is formulated with two molecular weights of Hyaluronic Acid alongside Vitamins C & E to support the hair fibre, enhance smoothness and promote a brighter-looking finish.

Unlike Kérastase Bain Ultra-Violet, Bain Lumière is not a purple shampoo. It does not use purple pigments to neutralise yellow or brassy tones, making it an excellent everyday cleansing shampoo for maintaining blonde hair between colour appointments.

Who is it best for?

Kérastase Blond Absolu Bain Lumière may suit you if your hair:

• is blonde, bleached, highlighted or lightened
• is naturally blonde and needs extra brightness
• looks dull or has lost its salon-fresh luminosity
• needs hydration without a heavy finish
• is exposed to pollution and other dulling agents
• needs a regular shampoo between purple shampoo treatments
• feels dry following colouring or lightening
• needs a lightweight shampoo suitable for frequent washing

What problem does it solve?

Lightening and highlighting can leave hair feeling dry and looking dull, while everyday exposure to pollution and other environmental factors can further reduce its brightness.

Bain Lumière combines gentle cleansing with lightweight hydration. It helps remove pollution and dulling agents while leaving the hair feeling hydrated, weightless and luminous.

Think of Bain Lumière primarily as your hydrating and brightening blonde maintenance shampoo, rather than your brass-neutralising treatment.

If unwanted yellow or brassy tones are your main concern, Kérastase Blond Absolu Bain Ultra-Violet Shampoo is the more appropriate purple shampoo.

Key ingredients

Hyaluronic Acid: The formula contains two molecular weights of Hyaluronic Acid. According to Kérastase, the lower molecular weight works within the hair fibre to help improve resistance, while the higher molecular weight helps enhance smoothness and provides a plumping effect.

Vitamins C & E: Used together to help brighten the hair fibre's cuticle and support the integrity of the hair fibre.

Edelweiss Flower Extract: Also present within the formula as Leontopodium Alpinum Flower/Leaf Extract.

How to use

Apply Kérastase Blond Absolu Bain Lumière Shampoo to wet hair and work into the scalp and lengths. Lather, then rinse thoroughly.

For blonde hair that develops unwanted yellow or brassy tones, alternate Bain Lumière with Kérastase Blond Absolu Bain Ultra-Violet Shampoo as required.

Millies Expert Advice

If you want to maintain bright blonde hair but don't need to neutralise brassiness every time you wash, Bain Lumière is the better everyday choice within the Blond Absolu shampoo range.

Use Bain Lumière for regular cleansing and hydration, then introduce Bain Ultra-Violet when unwanted yellow or brassy tones appear. Follow with Cicaflash Conditioner through the mid-lengths and ends to add hydration without unnecessarily weighing the hair down.

Is Kérastase Blond Absolu Bain Lumière right for me?

Choose this shampoo if: your blonde, highlighted or lightened hair needs regular cleansing, lightweight hydration and improved luminosity without the toning action of a purple shampoo.
