Kérastase Blond Absolu Bain Ultra-Violet is a purple toning shampoo for blonde, highlighted, grey and silver hair. Its violet pigments neutralise brassy yellow tones in a single wash while hyaluronic acid keeps hair hydrated — so blonde stays cool and luminous without the dryness most purple shampoos cause.

Benefits
  • Neutralises brass — violet pigments cancel yellow and orange tones instantly.
  • Cooler, brighter blonde — restores ash, platinum and silver tones.
  • No dryness — hyaluronic acid hydrates while it tones, so it's safe for regular use.
  • Antioxidant protection — edelweiss extract helps guard against colour fade.
How to use
  1. Apply a generous amount to wet hair, scalp to ends, and lather.
  2. Leave 2–5 minutes — longer for a cooler result, up to 10 for very brassy hair.
  3. Rinse, and follow with Cicaflash conditioner or Masque Ultra-Violet. Use 1–3 times a week.

Why our stylists rate it
From the Partners Hair team
Kérastase Blond Absolu Bain Ultra-Violet is a purple toning shampoo for blonde, lightened, highlighted, or naturally grey hair. Part of the Kérastase Blond Absolu range. Cleanses while neutralising brassy yellow and orange undertones with concentrated blue and violet pigments.

Best for: blonde or lightened hair showing brassy, yellow, or orange undertones; cool-toned blondes maintaining a fresh salon tone between visits; the tone-correcting cleansing step alternated with Bain Lumière (daily hydrating shampoo) on non-toning wash days.
Less suited to: daily use on every wash (use Bain Lumière for non-toning days — purple shampoo can over-deposit pigment if used too frequently); brunette or red colour-treated hair (use Chroma Absolu range — Bain Chroma Respect); non-coloured natural hair seeking general care (use Kérastase Nutritive or Genesis ranges); severely damaged hair primarily needing intensive repair (start with Cicaextreme treatment before introducing toning shampoo).

Key actives:
- Ultra-Violet Neutralisers — concentrated blue and violet pigments (Acid Violet 43 / CI 60730) that immediately deposit on the fibre to cancel brassiness and yellow undertones
- Hyaluronic Acid (Sodium Hyaluronate) — ultra-concentrated, strengthens hair and prevents future breakage; offsets the dryness purple shampoos can sometimes cause
- Edelweiss Flower extract (Leontopodium Alpinum) — antioxidant-rich, protects sensitised hair against daily damage and softens fibres
- Hydrolysed Wheat Protein — supports fibre strength
- Gentle cleansing base — removes excess oil and impurities

Benefits:
- Neutralises brassy yellow and orange undertones in one wash
- Maintains cool, bright blonde or silver tones between salon visits
- Hydrates while toning — unlike many purple shampoos, the hyaluronic acid offsets dryness
- Strengthens hair and protects against breakage
- Prolongs the "salon-fresh" finish for up to 2 months with consistent use

How to use: Apply to wet hair. Massage through lengths and ends to lather. Leave on for 2–5 minutes depending on how much tone correction is needed — longer for heavier brassiness, shorter for maintenance. Rinse thoroughly. Use as often as needed for tone correction; alternate with Bain Lumière on non-toning wash days. Follow with Cicaflash conditioner or Masque Ultra-Violet for stronger neutralisation.

Format: 250ml shampoo.

Before you buy
Common questions

What does purple shampoo do?

Purple shampoo deposits violet pigments onto blonde, lightened or grey hair to neutralise yellow and brassy tones. Purple and yellow are opposite on the colour wheel, so they cancel each other out — leaving hair cooler and brighter.

How often should I use purple shampoo?

1–3 times a week, depending on how quickly your colour goes brassy. Start with once a week and increase if needed. Daily use is safe with this formula thanks to the hyaluronic acid, which prevents dryness.

Can I use purple shampoo on grey or silver hair?

Yes — it works equally well on natural grey, silver and white hair to remove yellow tones and restore brightness.

How long do I leave purple shampoo on?

2–5 minutes for regular toning, and up to 10 minutes for more intense brassiness. The longer you leave it, the cooler and more violet the result — start short and build up to find your ideal tone.

Is Kérastase the best purple shampoo for blonde hair?

Kérastase Blond Absolu Bain Ultra-Violet is consistently rated among the best purple shampoos for combining effective toning with hydration — most purple shampoos dry hair out, this one doesn't.
