Blond Absolu — Complete Guide
The Kérastase range dedicated to blond, bleached, highlighted, grey, or white hair. Four objectives: hydrate the fiber, repair damage from bleaching, protect against breakage and external aggressors, and neutralize unwanted brassy tones.
About the Range
Blond Absolu aims for four main objectives: hydrating the fiber, repairing damage related to bleaching, protecting against breakage, and neutralizing unwanted brassy tones. The formulas are primarily based on hyaluronic acid, edelweiss flower, vitamins C and E in some protective treatments, and, for purple treatments, ultra-violet neutralizers.
Key Ingredients of the Range
| Ingredient | Role |
|---|---|
| Hyaluronic Acid | Hydrates, plumps the fiber, and helps strengthen fragile blonde hair. In Blonde Guard, two molecular weights work inside and outside the fiber to help maintain hydration, softness, and suppleness. |
| Edelweiss Flower | Rich in antioxidants, it protects, softens, and helps repair the fiber. |
| Vitamins C and E | Antioxidants that help preserve the health, strength, shine, and hydration of blonde hair, particularly in Blonde Guard. |
| Ultra-Violet Neutralizers | Corrective pigments that help neutralize yellow and brassy tones. |
1. Bleached hair needs hydration — a layer of hydrating and nourishing active ingredients on the fiber's cuticle to prevent surface damage.
2. Bleached hair needs repair, protection, and neutralization — to strengthen the fiber, prevent breakage, and neutralize unwanted brassy tones.

Instrumental test protocol details are not provided in the source file.
Key Ingredients
Hyaluronic Acid: deeply hydrates and creates a protective barrier to retain moisture in the fiber. Two molecular weights work together: the lower one penetrates the hair fiber, while the higher one improves softness, flexibility and provides a plumping effect.
Vitamins C and E: antioxidants that form a protective shield to preserve shine and hydration. Vitamin C helps maintain the integrity of hair fibers and makes them more resistant to mechanical aggressions. Vitamin E helps protect hair from oxidative damage.
Science and Technology
Blonde Guard addresses the main factors that weaken blonde hair:
- Heat: Styling tools can weaken the cuticle and cortex, leading to protein loss, breakage and visible surface damage.
- UV Rays: UV exposure can rapidly degrade hair proteins and lipids, leading to discoloration, loss of shine, increased porosity and fragility.
- Chlorine: Pool chlorine acts as a powerful oxidizing agent, which can cause blonde hair to yellow, lose shine, and become more porous and difficult to detangle.
- Salt Water: It can penetrate the fiber, increase surface porosity, and cause dehydration, leaving hair rough and dull.
- Dehydration: All of these factors can lead to dryness, roughness, and loss of shine. Daily use of a protective and hydrating leave-in treatment helps maintain healthy and luminous blonde hair.
The effectiveness of Blonde Guard is based on the combination of hyaluronic acids and vitamins C and E: hyaluronic acids help hydrate the fiber inside and out to keep hair more supple, softer and plumper; vitamins C and E act as antioxidants to help preserve strength, health and shine.
Directions for Use
- Apply to clean, towel-dried hair.
- Distribute evenly from mid-lengths to ends. In-salon, apply evenly strand by strand at the styling station.
- Do not rinse.
- Allow to air dry or blow-dry.
