Kérastase’s Genesis Serum Strengthens Hair

I’m a fan of any beauty product that requires minimal effort. As someone who lacks consistency in most routines, I found that a simple approach is the only way that sticks, especially when it comes to my hair care. Truthfully, hair serums have proven to be the easiest and most effective way for me to see improvements in my hair’s health and growth. After all, all it takes is a few drops massaged into your scalp to make all the difference. While looking for a new formula to fight damage, I stumbled on the Kérastase Genesis Hair Serum, which immediately piqued my interest.

Kérastase Genesis Hair Serum 

This lightweight hair oil is beneficial for those experiencing hair shedding caused by breakage from brushing. Because let’s face it — detangling knots can be difficult, often resulting in tugging and yanking that weakens hair. Fortunately, this revitalizing formula is packed with strand-strengthening ingredients like edelweiss, arginine, and ginger root to prevent further hair loss as well as encourage hair regrowth. Plus, ginger root is great for calming inflammation that can contribute to hair loss and scalp irritation. It also has antimicrobial and antifungal properties to fight conditions like dandruff. Another bonus? This daily, Kerastase Genesis serum features a woody citrus fragrance to add a fresher scent to your hair. 

Reviewers were impressed with the strengthening serum’s hair-enhancing results. “My hair was feeling weak, shedding more than usual, and looking flat—but this serum has brought it back to life,” said a shopper who added they noticed “less breakage, stronger roots, and even a boost in volume” after a few weeks. A second user raved that their hair fall out is “basically nonexistent,” while their baby hairs are “growing in’ and bald spots are “getting filled in.” Similarly, a final shopper shared that the hair oil left their “significantly fuller” with “tons of new baby hairs” as well. 

Keep in mind, though, this fortifying treatment is not a product formulated to treat specific medical hair loss conditions. If you’re looking for products that help with denser or longer look, you might want to consider the brand’s similar products like the Initialiste Scalp and Hair Serum, Résistance Extentioniste Scalp and Hair Serum, or the Densifique Bain Densité Shampoo.

The Kérastase Genesis Serum is still a must-try if you want to achieve stronger strands that can lead to healthy hair growth. More than 10,000 shoppers even bought it in the last month at Amazon, and it’s available for $64 at the retailer and the brand’s site.
