I’ve known about Hard as Hoof since I was a teenager, and there are so many people who swear by this product. If you don’t mind a slightly thicker texture, this jojoba oil- and calcium-infused formula instantly starts working to maintain hydration levels in your nails and cuticles, and stop cracks in their tracks. There’s a reason this boasts nearly 50,000 five-star reviews on Amazon.

An Amazon reviewer says: “Seriously blown away by this. I have hypothyroidism, and even with medication, my nails are always thin, flimsy, slow growing, and brittle. I’ve never been able to grow them long in my life, and I’ve always wanted natural, long nails because I hate the feeling of all the types of fake nails. (Also hate the cost of having to get and upkeep them.) I used this cream directly on my nails and right at the base of the cuticle every night before bed for maybe a week, and I instantly saw my nails grow faster, and they haven’t been breaking, tearing, or anything like that. This product is a complete game changer.”
