Those who caught my recent empties post will know I gave the Kerastase Gloss Absolu range a try via some travel sizes. It did not work for me. My hair felt coated in a way I did not enjoy, as though it had been laminated rather than cleaned. So I returned, without much hesitation, to the Résistance range, which has been a reliable favourite for some time. The Kerastase Resistence Strengthening Shampoo is quite possibly my favourite shampoo. That is not a claim I make lightly.
What is it?
A strengthening and fortifying shampoo for dry, brittle hair.
What Do I Think?
The Résistance Bain Force Architecte is quite possibly my favourite shampoo. That is not a claim I make lightly.
My hair is thick, though thinning more than I would like as I get older, and chronically dry. Finding a shampoo that hydrates without weighing everything down is harder than it sounds. Too much moisture and hair becomes difficult to style. Too little and it feels brittle and looks dull. This one gets the balance right.
The formula uses a Vita-Ciment Complex to lift away dirt and impurities while strengthening the hair and helping to prevent breakage and split ends. My hair is not damaged, but I find that the nourishment this provides makes a visible difference. Hair feels soft and sleek after washing without any of the residue or plasticky quality I experienced with the Gloss Absolu.
A quarter-sized amount is enough to produce a good lather, which means one bottle lasts me three to four months at least. Kérastase is not cheap, and I will not pretend otherwise. But the longevity makes the cost considerably more reasonable when you break it down.

Would I recommend?
If dry or brittle hair is something you contend with, this is worth trying. It is one of those products that does exactly what it promises, every time, without drama.
