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.

Great shampooI've been using this shampoo with 2 other products from this series and honestly I didn't think that i will see such a difference. I have bleached hair that can often feel dry and look dull but after using this shampoo it kind of looks healthier.
It cleanes my hair gently but effectively. I dont get this horrible squeaky clean feeling after using it - my hair feels nicely hydrated instead. I noticed more shine from the very first use. My ends looks better too, with less frizz. As for my colour - it looks fresher and brighter. It's not a typical purple shampoo, so it doesn't cool down the colour but it definitely brings back the shine.

Best shampoo for blonde hairI was amazed how good this shampoo it. Removes the build up from any product I used, leaves my hair very smooth and has a great smell. I recommend it especially forbleached blonde hair!

AmazingWow what a gorgeous product! The smell is delightful and I have not used a shampoo that has made my hair feel so soft before, it also instantly made my blonde hair look lighter and fresher. Hopefully this will save some trips to the hairdressers!

Amazing shampooI love the way my hair feels with this shampoo, it feels super cleansing and makes my scalp feel clean while not drying it out. Helps my hair feel less damaged. I don't have to use a lot of product for my hair to feel clean.

Great shampooThe shampoo scent nice and after hairs feels nice and soft . The shampoo texture feels and looks like gel. I can tell that this shampoo suited my hairs. Because I love how it looks after wash and it’s not greasy or with some unwanted undertones

OkayI have been using this product with the cicaflash conditioner and I have to say I am quite disappointed, before trying this shampoo and conditioner I was using the kerastase gloss absolu which is my all time favourite, so I was hopeful that because I have bleach blonde hair that it would be the same silky soft feel with a more brightening blonde affect. Unfortunately this shampoo and conditioner feels quite drying on my hair and I didnt notice a difference in the colour of my hair either! Its not a bad shampoo but it’s not the best one that kerastase do

Good for softness, less for brightnessNice shampoo, good texture & lather, definitely helps my hair feel softer but I didn't notice much impact to brightness. My hair needed a wash within a couple of days of using which is standard, so adequate scalp cleaning but not better than other products I've tried in this regard. Packaging is beautiful and looks great in my shower.

Does the jobIt's a great shampoo with an amazing fragrance, but the packaging design is very inconvenient if you have a shower/little space to place the cap somewhere. A flip cover would be so much more convenient to use.
