Olive & June Nail Strengthener | Heals & Conditions Weak, Brittle Nails | Up to 77% Increase in Strength | Prevents Peeling & Ridges | Celery Seed + Flora Complex | Vegan, Cruelty-Free Nail Treatment

Say hello to your strongest nails yet with the Olive & June Nail Strengthener—a clean, plant-powered formula designed to restore and protect nails that are weak, brittle, peeling, or prone to breakage. Whether used as part of your weekly mani or a dedicated treatment, this multitasking formula helps your natural nails become healthier, stronger, and visibly improved. In a consumer wear study with 50 testers, users experienced an average 77% increase in nail strength when the product was used correctly—making this a powerhouse in nail care. It’s especially ideal for those recovering from damage, breakage, or just looking to give their natural nails a boost of strength. Powered by Celery Seed Extract and Flora Complex, the Nail Strengthener helps heal and condition the nail surface—reducing white spots, smoothing ridges, and preventing peeling. And thanks to the Flora Complex, a blend of flower-based nutrients, your nails get a gentle but effective dose of nourishment right at the nail plate. As an added bonus, not only does Nail Strengthener help your nails feel stronger, it also contains nail priming ingredients to help your polish last longer by 2-3 days. Use it weekly as a primer substitute before applying your favorite Olive & June polish, or go all in with an intensive treatment: apply daily to bare nails until the desired strength is achieved. It fits seamlessly into your routine and elevates your nail health in just a few uses. Like all Olive & June products, our Nail Strengthener is vegan, cruelty-free, and made to bring salon-quality care straight to your fingertips. Beautiful and strong nails start here.
