A Celebrity Colorist Complimented My Hair After I Started Using This Specific Product, and It's Finally Back in Stock
If you're low-maintenance (and admittedly, a little lazy) like I am, I have a beauty secret that you'll definitely want to hear. For background, I've been highlighting my hair for 14 years, and within the past year, I finally started using products specifically meant for lightened hair. I always thought these products were pointless and wouldn't actually make a difference in my blonde hair, but one of my recent highlighting appointments proved me so wrong.
A few months back at my appointment, my colorist (who has worked with many celebs, BTW) said my hair looked so fresh and bright. I credit this to Kérastase's Blonde Absolu line, specifically its Blonde Guard Wonder Shield Spray ($50). From the nourishing, salon-quality ingredients to the protective formula, there's so much to love about this top-tier product. The only thing I don't love is that it's so good it's constantly selling out. But it's finally back in stock, so you know I'm grabbing as many bottles as I can. If you also want the best blonde of your life, keep scrolling to shop all the Kérastase essentials I recommend.
Protects Your Hair Against Aggressors
I recently learned that a variety of factors can influence how quickly your blonde hair fades, especially over the summer. Heat-styling, UV rays, chlorine, and saltwater can all have a negative impact. Using Kérastase's Blond Absolu shampoos, conditioners, masks, serums, and more helps protect against these aggressors. The Blonde Guard Wonder Shield Spray ($50) is the ultimate all-in-one blonde-protecting product—spritz it on for extra protection before you heat-style your hair or go out in the sun, and you'll thank me later. It's one of those essentials you can also use every day at home as a leave-in conditioner to detangle and protect your hair from heat before blow-drying.
Effortless Blonde Maintenance
Kérastase's Blond Absolu line is specifically designed to help you maintain the vibrancy, brightness, and softness of your lightened or highlighted hair. And it did its job, as was evident when my colorist complimented my hair after I went five months between coloring appointments. So how is this possible? The Blond Absolu line protects from fading, reduces brassiness, and nourishes and protects your hair to help you maintain your best, most vibrant blonde for longer. It's the golden ticket to keep your blonde hair shiny, hydrated, and bright for up to two months between salon visits—although it evidently allows me to go much longer than that!
Premium Salon-Quality Ingredients
Kérastase is known for its premium haircare essentials, and its entire Blonde Absolu line features professionally trusted ingredients, including vitamins C and E and hyaluronic acid, which brighten and hydrate your hair just like they do your skin. It also has ultraviolet pigments that neutralize brassiness and natural botanicals such as edelweiss flower that give your hair that glossy, salon-worthy finish from home.
