Kérastase Blond Absolu Masque Ultra-Violet is a purple toning hair mask for blonde, grey and lightened hair. Its concentrated violet pigments neutralise brassiness more deeply than a purple shampoo, while hyaluronic acid seals in moisture — leaving blonde cool, bright and soft, never dry.

Benefits
  • Deep toning — concentrated violet pigments correct brass more intensely than shampoo alone.
  • Cooler blonde — restores ash, platinum and silver tones.
  • Lasting moisture — hyaluronic acid keeps hair soft and shiny while toning.
  • Less colour fade — edelweiss helps protect tone between salon visits.
How to use
  1. After shampooing, apply generously to damp mid-lengths and ends, avoiding the scalp.
  2. Leave 3–5 minutes, up to 10 for stronger brass, then rinse.
  3. Use 1–2 times a week, ideally after Bain Ultra-Violet for the best result.
Who it's for

Best for blonde, grey or silver hair that needs deeper toning than a shampoo gives. See how to use purple shampoo, how to get rid of brassy hair, or the full Kérastase range.

Why our stylists rate it
From the Partners Hair team
Kérastase Blond Absolu Masque Ultra-Violet is a purple toning hair mask for blonde, lightened, highlighted, or naturally grey hair. Part of the Kérastase Blond Absolu range. Deeply nourishing treatment that neutralises brassy and yellow undertones while restoring hydration and softness.

Best for: blondes needing both intense conditioning and tone correction in one weekly step; lightened or grey hair with strong yellow or orange brassiness; the weekly intensive treatment step in a complete Blond Absolu routine alternated with Cicaflash conditioner on non-toning wash days.
Less suited to: severely bleach-damaged hair primarily needing repair (use Cicaextreme masque for damage-focused weekly treatment); brunette or red colour-treated hair (use Chroma Absolu range); non-coloured hair seeking general nourishment (use Kérastase Nutritive — Masquintense Thin or Thick depending on hair type); hair with only mild yellowing where a shampoo-strength toner is sufficient (use Bain Ultra-Violet alone).

Key actives:
- Ultra-Violet Neutralisers — concentrated violet pigments (Acid Violet 43 / CI 60730 and Acid Red 52 / CI 45100) that deposit on the hair to cancel brassiness
- Hyaluronic Acid (Sodium Hyaluronate) — fills and heals fibre wounds from within, hydrates and strengthens
- Edelweiss Flower extract (Leontopodium Alpinum) — antioxidant-rich, protects hair from daily damage
- Mallow Flower extract (Malva Sylvestris) — supports cuticle softness and shine
- Rich, creamy treatment base — penetrates the hair fibre for intensive nourishment

Benefits:
- Neutralises brassy yellow and orange undertones in a single weekly application
- Restores up to 91% more hydrated hair (Kérastase instrumental test)
- Nourishes the hair fibre while toning — combines mask-level conditioning with anti-brass action
- Helps preserve cool, bright blonde or silver tones for longer between salon visits
- Non-staining when used as directed — will not turn hair purple

How to use: Apply to shampooed and towel-dried hair. Massage through lengths and ends. Leave on for 3–5 minutes for light tone correction or up to 10 minutes for stronger neutralisation. Rinse thoroughly. Use weekly, or alternate with Cicaflash conditioner on non-toning wash days.

Format: 200ml mask.

Before you buy
Common questions

What is the difference between purple shampoo and a purple hair mask?

Purple shampoo tones during cleansing, but contact time is short. A purple hair mask has more concentrated violet pigments and stays on longer, for a deeper, more lasting result. Used together they give the best outcome.

How long do I leave a purple hair mask on?

3–5 minutes for regular maintenance, and up to 10 minutes for heavily brassy hair. Don't exceed 15 minutes, as over-toning can leave a violet cast.

Can I use a purple hair mask 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 often should I use a purple hair mask?

Once a week for maintenance, and up to twice a week if brassiness develops quickly or after bleaching.
