Whatever your blonde hair: you dare, we care. The Blond Absolu collection provides intense nourishment and instant brightness to achieve a perfect blonde.
Blond Absolu maintains and perfects cool tones through deep ultra-violet neutralisers, intensely nourishes the hair fibre, and brightens hair.
KEY INGREDIENTS
Vitamins C+E Vitamin C & Vitamin E combine their power to brighten the fibre's cuticle and help maintain the integrity of the hair fibre.
Hyaluronic Acid Within this formula, two distinct molecular H.A. weights are used. The low molecular weight H.A. penetrates the hair fibre, improving resistance, while the high molecular weight enhances smoothness and provides a plumping effect. When combined, this dual-action effect helps to deliver benefits both on the inside and outside of the hair fibre.

Gentle shampooThe Kerastase Blond Absolu Bain Lumiere Shampoo is a gentle shampoo that effectively cleanses blonde hair. It has a gel texture which is lightweight and lathers well. The inclusion of hyaluronic acid hydrates the hair strands so it doesn't dry out the hair like some other shampoos. The shampoo is great at removing impurities and illuminating light coloured hair. The shampoo smells glorious with notes of edelweiss flower. I have used it in combination with other products from the same range and my hair looks amazing.

Brighter, Softer & More Radiant BlondeI’ve been really enjoying using the Kérastase Blond Bain Lumière Shampoo. My blonde hair can sometimes feel dry and look a little dull, so I love how gently this shampoo cleanses while helping my hair look brighter and more radiant.
The texture feels luxurious and a little goes a long way. It creates a lovely lather and leaves my hair feeling clean, soft and lightweight without making it feel stripped or dry. After washing, my hair feels smoother and looks much more fresh and shiny.
I also love how my blonde looks after using it -brighter, healthier without changing the tone of my hair. It’s definitely a shampoo I would reach for when I want my blonde to look fresh and polished.
Overall, a beautiful shampoo for blonde hair and a lovely addition to my haircare routine!

Absolutely gorgeousThis shampoo is probably the best I’ve ever used! It leaves my hair feeling so soft after use, and it suds up enough to cover my whole hair without being overwhelming. The scent is gorgeous and it lasts all day. I’ve had compliments from friends at how silky my hair looks and how lovely it smells. I would highly recommend this.
