It’s time for another Splurge or Save 💁‍♀️✨ And today we’re talking about overnight hair serums. If you’re dealing with dry, brittle, dehydrated hair—especially from heat styling, coloring, or just aging hair—you may want to add one of these to your routine. ⭐ SPLURGE: Kérastase Nutritive 8H Magic Night Serum This has been a favorite of mine for a while. I use it often on my hair shafts before bed, and by morning my hair feels softer, smoother, and much less brittle. I love that it works overnight while you sleep—easy, no extra effort, and you wake up with hair that feels revived. ⭐ SAVE: L’Oréal Elvive Hyaluron Plump Overnight Serum Here’s the interesting part—L’Oréal Group owns Kérastase, so sometimes you’ll find overlapping technologies, ingredients, or similar formulations across brands. Is this an exact dupe? No. But it delivers very similar nourishing and hydrating benefits at a much friendlier price point. I especially like this one for those with thicker, coarser, or curlier hair textures, where that extra hydration can really make a difference. So… Splurge or Save? If you want the luxe experience and salon-quality formula, go with Kérastase. If you want great results without spending as much, L’Oréal is a fantastic option. Either way, overnight hair care can make a huge difference—especially as our hair changes with age. haircare LTKgrwm LTKdayinmylife LTKBeauty
