Editor's Pick: Kérastase Résistance Bain Extentioniste Shampoo

I am always working on my next big hair move. After ambitiously cutting my dark brown hair into a lob during the summer (a move that seemed genius given the sweltering temperatures), I’ve worn out every possible way to style a short baby ponytail or a chignon. And so, I arrived at a new hair goal: Length. I want the kind of healthy long hair that models in shampoo commercials tie into knots and toss around in slow-mo for the camera, and I want it soon.

Thanks to my job in the hair world, I was able to start off my quest with the aid of mane technology’s latest and greatest: Kérastase Résistance Bain Extentioniste Shampoo, a product specially formulated for long hair (and those hoping to get it there without major breakage) that I received from the brand.

To get the details about my personal hair journey and why I can’t stop using the shampoo in the turquoise bottle, keep scrolling.

Why Use Kérastase Résistance Bain Extentioniste Shampoo

If I’m being completely honest, Kérastase nearly always has a place in my shower because I’m a sucker for beautiful packaging and luxurious hair-washing experiences that makes me feel like I’m in a spa. Tack on the delicate floral scent and creamy feel—baby, I’m in love.

Because I have very healthy virgin hair, I don’t normally worry about breakage or split ends. In the winter, however, the dramatic temperature changes in New York and constant parka hood friction leave my ends feeling a little crispy and under-nourished. If you’ve ever aimed for long hair, you know the golden rule: Preserve every centimeter of length as long as possible.

As a bonafide hair product snob, what’s most important to me is the way the shampoo strengthens and fortifies my hair when used as a system with the line’s Masque. Stronger hair means I get to my hair length goals all the faster. Catch me on the beach this summer, long hair floating in the fresh breeze!

How To Use Kérastase Résistance Bain Extentioniste Shampoo

Unlike many women, I like to wash my hair every day because it tends toward oiliness—which means Bain Extentioniste and I come into contact every morning. Water temperature on lukewarm, I thoroughly wet my hair before applying a coin-sized dollop of shampoo to my scalp. I generally opt for soft, massaging circles instead of using my nails to scrub.

Finally, I rinse the shampoo suds out of my hair until the water runs clear and move onto the next step in my cleansing routine—generally wringing excess moisture out of my mane and applying a dollop of Fondant Extentioniste Conditioner to my mid-lengths and ends. While it sits, I take care of all the other important body business to get done in the shower (legs don’t shave themselves, after all). As a final step, I rinse my hair and move on with my day.

If you’re looking for a hair care system that will help you on your way to mermaid-length hair, Kérastase Résistance Bain Extentioniste Shampoo may just be your ultimate ally.
