Kerastase Resistance Fibre Architecte, Erosion Level [1-2], 1.01 Ounce

Product that was delivered was defective as the duo-chambers both distributed as a serum-like consistency. This product comes as a duo-pump dispenser and suppose to dispense as, one-side as a serum-like consistency and the other side as a milky/creamy consistency. Can't comment on the item because contents is not as expected so there-fore will have to discard the item because it can't work as supposed to in helping to protect my hair. Very disappointed as lost my money on this item that was delivered.

I have bought this product a few times from my hairdresser's salon, but since I moved and can't find this anywhere I had to order online. I was unpleasantly surprised when I did my usual 3 pumps and instead of a clear serum and white serum being dispensed, it was all clear. This is not the true Fibre Architect, so I'm not sure why this continues to be sold and passed off as the real thing. Please don't buy this.

Not the real stuff! Knock off... BEWARE!!!

I have very dry ends due to years of highlights. I get it cut regularly and my stylist uses a low bleach solution but still dry, fried looming ends. I heard about this line from one of Mt favorite beauty bloggers so tried it with cautious optimism. IT WORKS ON DRY ENDS. Bottom line - I would definitely recommend this. I add 2 pumps to my hands, rub and massage into the ends of my hair. Then whatever left on hands I run through the roots. My hair looks 50% better after 7 days. In another 7 I imagine it will improve .

I have been a Kerastase user for many years in both my home and salon life! If you abuse your hair with color and hot tools then you will love this. I had platinum blonde hair for over 10 years and and I’m naturally dark brown hair, it made my hair look beautiful and healthy!

Not authentic at all!!

Use on damp hair for a smooth, full blowout ... or on dry hair with a hot iron for the ultimate polish. This continues to be my go-to for my fine, highlighted and bobbed hair. And it's the only Kerastase that's light enough to use every day (my hair does NOT sleep well).

Does not weigh hair down.

For me i not see any changing i use it my hair still dry now is alredy 1month

My hair is not overly damaged but I use this as it protects my hair form blow drying and it smooths it without leaving any residue.

The best item!Thanks

Love this product, use it again and again

I have noticed an improvement in the condition of my hair, I still have a long way to go though
