I was given the opportunity to trial the Kérastase Blond Absolu range, and I am so grateful - this is an effective anti-brass product that I will certainly purchase. Overall I would definitely buy this again. The mask is a bright “whoooaaa” in-your-face electric purple, so no surprise it’s so effective! We love to apply a quarter-size dollop of Kérastase Elixir Ultime Le Masque Hair Mask to our mid-lengths and ends before massaging it. After that was a quick scalp scrub on my dry hair, and a wash with Bain Chronologiste shampoo. Tracy Ryan 10 Mar 2019 I was lucky enough to get to trial this product range on my bleached platinum blonde and white/ grey hair. I found this product to be very nourishing and conditioning. The contents were lovely, once again the fragrance was subtle but lovely and the product was nice on my hair and made it feel soft and bouncy. I loved this product, I was a little concerned by the very bright purple and consequently didn’t leave it on as long as recommended, however I needn’t have worried , next time I will leave it in longer, it left my hair feeling very silky and smooth. First thing I noticed was the very bright color. I have noticed a decrease in the small brassy patches i had and my hair is lovely and shiny now, where it had been looking a little dull previously. My hair is incredibly soft and bright after each use! My damaged hair doesn't feel like it's been chemically treated. It removed the brassy tones and left my hair feeling super soft and bouncy. I left the product in for 20 mins for the the first application and then 10 mins for consecutive treatments. I trialled the Kerastse Blond Absolu Bain Lumiere (shampoo) together with the Masque Ultra-Violet (mask) and Cicaplasm (leave-in serum). It left my hair feeling soft and silky and my blonde looked very fresh. I did find underneath my hair was a little greasy but I suspect tgat may have been due to the amount of product Ibused. Love the jar but admit to being concerned when opened and saw the purple colour! However I need not have been worried at all. The packaging looks pretty but isn't really functional as its difficult to hold the gel and place the lid back on. I'm not sure the trial was long enough to fully evaluate the products so I will continue to use them. The packaging is luxurious and the smell is divine. I've used almost every purple shampoo out there and this would definitely be in my top 5. Definitely a great hair masque and definitely a splurge item. This masque was effective in neutralising brassy tones in my hair. "Use Bain Ultra-Violet to get an instant & powerful shot of anti-brass. My hair needed a good treatment and I had tried other products to get rid of any brassy or yellow tones. The brassy tones were neutralised and there was a nice shine to my hair. Love the scent and the texture too. A unique combination of Hyaluronic Acid, Edelweiss flower and powerful Ultra Violet neutralizing pigments: Aqua / Water - Cetearyl Alcohol - Paraffinum Liquidum / Mineral Oil - Dipalmitoylethyl -Hydroxyethylmonium Methosulfate - Cetyl Esters - Cetrimonium Chloride - Citric Acid - Sodium Benzoate - Sodium Hydroxide - Caprylyl Glycol - Salicylic Acid - Ci 60730 / Acid Violet 43 - Limonene - Glycerin - Sodium Hyaluronate - Tocopherol - Ci 45100 / Acid Red 52 - Leontopodium Alpinum Flower/Leaf Extract - Malva Sylvestris Flower Extract / Mallow Flower Extract - Potassium Sorbate - Parfum / Fragrance. Leaves my hair shiny, and gives a subtle ashiness to my blonde highlights, smells The first time I used it I used a generous amount, left it in for ten minutes and when I rinsed it out could not believe how easily my hair combed through and how soft it left my hair. The only thing I didn't like is the design of the container, the opening is too small? Play it cool with Kérastase Blond Absolu Masque Ultra Violet.
