This French Girl-Loved Beauty Brand Just Launched A Scalp Serum That May Give You Your Healthiest Hair Ever

There’s no denying that the beauty spotlight has been shining on scalp care for quite some time now. But between the millions of posts from experts and influencers sharing their advice across Instagram and TikTok (there’s even a dedicated #ScalpTok hashtag on the latter) and all of the new products launching in the hair care space, it can be hard to know where to start. That’s where the iconic French hair care brand Leonor Greyl comes in, with its new fuss-free hair and scalp serum — because if there’s one ever-trending topic, it’s the French girl beauty routine.

Leonor Greyl’s Serum Énergisant is a luxe blend of botanical ingredients that boast benefits ranging from rebalancing the scalp to increasing hair shine and even encouraging hair growth. Though its $120 price tag is admittedly a splurge, the serum is available for less than $100 from May 1 to May 31 when you use the code ‘20LGSERUM’ to receive a 20% discount (that brings the price down to $96).

Before getting to the serum specifics, for those who are unfamiliar with the brand, Leonor Greyl is a staple in French pharmacies (and my personal go-to shampoo whenever I’m in Paris). Falling a bit more on the luxury side than your typical drugstore beauty brand, Leonor Greyl has prioritized using botanical ingredients to improve the health of the hair and soothe sensitive scalps since its launch in 1968.

In keeping with the brand’s ethos, Leonor Greyl’s Serum Énergisant is a vegan and cruelty-free formula that comprises 99% natural ingredients, and perhaps more importantly, is made without common irritants and ingredients (like silicones, phthalates, parabens, and alcohols) that can secretly contribute to dryness and scalp buildup. Primarily created to reduce hair thinning by restoring the health of the scalp, the serum’s hero ingredients include organic rosemary extract, organic Indian gooseberry, and organic maca extract. Rosemary in particular has been shown in studies to be as effective as Minoxidil treatments when it comes to hair growth, while Indian gooseberry extract’s traditional use as a hair tonic for promoting hair growth was among a blend of ingredients that proved to be helpful in a clinical study.

Because a healthy scalp is essential for healthy hair, the serum also includes multiple plant-based ingredients aimed at nourishing the skin on your scalp and keeping your hair protected. Chief among them, you’ll find ingredients like glycerin, panthenol, and lactic acid to moisturize and balance the scalp’s pH level, as well as antioxidant-rich extracts like green tea, licorice root, and alfalfa to help protect both the scalp and hair from damage caused by pollution and UV exposure. Plus, there are nearly a dozen amino acids in the formula to leave hair shiny and soft, including arginine and lysine, which are believed to promote blood circulation to the hair follicle, as well as collagen production.

You only need to use the serum once weekly to begin to see the benefits, but for severe hair thinning, Leonor Greyl recommends treating the scalp as often as three times a week. The Serum Énergisant is suitable for all hair types, though it was specifically created for those trying to tackle thinning hair. And because it’s free from color-stripping sulfates and includes ingredients that shield hair from environmental damage, it’s especially great for those with color-treated hair who are looking for products that provide color protection.
