No more brittle nails.
I've always had a love-hate relationship with my nails. They’ve always been prone to breaking, peeling, and chipping When I stumbled upon Onyx Hard as Hoof strengthening nail cream, I admit I was skeptical, but my desperation won out. And let me tell you, I am so glad it did. From the first application, I was pleasantly surprised. The cream itself isn't greasy and absorbs fairly quickly, which is a huge plus for someone who's constantly on the go. Honestly, I didn’t follow the directions. At first, I started applying it just once a day, before bed. Within a week, I started noticing a difference. My nails, which usually felt flimsy and would bend easily, felt noticeably firmer. The peeling, my biggest nemesis, seemed to be less frequent. By the end of two weeks, I was genuinely impressed. My nails were not only stronger, but they also looked healthier. They had a natural sheen to them that I hadn't seen in years. Now, after using Onyx Hard as Hoof for a little over three months, I can confidently say this stuff is a game-changer. My nails are significantly harder – I can actually tap them without fear of them bending or breaking. I haven’t had a break, split or chip in weeks. They're stronger than they ever have before without splitting, and the constant peeling has practically disappeared. It's not a miracle cure that will make your nails indestructible overnight, but with consistent use, it truly delivers on its promise. If you're like me and have struggled with weak, brittle nails, I wholeheartedly recommend giving Onyx Hard as Hoof a try.

Buy It
As a recovering nail biter, I can't recommend this product enough. I've used plenty of cuticle oils in the past, but nothing has made my nails look and feel as healthy as this stuff. For the first time in my life, quite literally, my nails feel strong. If, like me, you are looking to kick your nail biting habit, here's my advice: 1. Moisturize your nails and cuticles with this stuff! Several times a day especially after hand washing. A little goes a long way! 2. Stop trimming your cuticles. Don't do it. Throw your cuticle nipper away! 3. Clear coat of polish, remove and refresh once a week.

Great product that actually works.
This stuff is amazing! Seriously. I've had splitting nails on both big toes for years, and one worse than the other. I sure wish I had taken a before photo. Years ago my podiatrist said there wasn't anything to do for a nail splitting from the top, vertically down to the cuticle. He offered nothing. I fretted for years watching it get worse. Then I tried Kerisol. It's an oil treatment with tea tree oil. Used half the bottle following the directions and saw no improvement. That was 2 years ago. By now my right toenail has split about halfway down and has a notch in the top edge. My daughter had a jar of this at her house, unopened. I asked her if I could have it and she said she wasn't using it. The instructions say to apply it 3 x a day and that it can be applied over nail polish, which sounded odd. But the instructions say to apply it to the base, under the tip and around the edges, so the polish doesn't' matter. But when I don't have polish on I also rub it into the nail. I started with 3x a day for about 2 weeks, then went down to just morning and night and even missing sometimes. It's been a little over 3 months and I can't believe the difference. It is sandal season and I am no longer embarrassed of my toenails. The split is still slightly visible, but the notched area is growing out, looking better every time I trim. I expect that in another three months the notch and split will be completely gone. It takes time of course. The nail needs to grow out. I was afraid of losing my nails and now I go barefoot with confidence. A little goes a long way and I still have half a jar left. I have ordered two more and will keep using. GREAT PRODUCT that actually works. All podiatrists need to carry this in their offices.

Great for preventing nail splits
This stuff really helps keep my nails from splitting down the middle where I have deep ridges. The best part is that you don't have to always be painting your nails to keep them healthy looking. The only reason I didn't give it 5 stars is because you really do need to apply it at least three times a day to keep it working. I'm on my 3rd jar in three months and it does add up financially. In the long run, it's worth it to have healthy looking nails.

Good Ingredients, Non-greasy, and lanolin-free
The Onyx brand has a solid reputation, and their Hard as Hoof Nail Cream is no exception. My order arrived on time and in good condition. I bought the unscented cream which didn’t smell of added fragrances. It did have a light smell just by nature of the ingredients. It didn’t phase me. The texture is light and smooth. It massages into my cuticles and nails well, absorbs quickly, and leaves no greasy feeling. I also like that I can use it on bare nails or over polish. I’m allergic to lanolin (a wool-based ingredient) and wool, so I needed something without that. This fit the bill. As expected, it hasn’t caused any irritation. My nails tend to peel, split, and get brittle. I appreciate that Onyx Hard as Hoof Nail Strengthening Cream has ingredients to heal my nails and dry cuticles - shea butter, coconut oil, silk protein, jojoba seed oil, safflower oil, beeswax, vitamin E, provitamin B5, retinol. It has already helped soften my dry cuticles. I haven’t used it long enough yet to speak to long-term strengthening results but I expect that my nails will improve considerably. I’ll update this with long-term results after I’ve been using it longer. So far, I’m happy with it.

Should be a key part of your nail health routine!
I purchased this cream because I deemed 2026 the year of the nail rebuild! I had spent the better part of 10 years using gel manicures and recently gel strips or press ons, and my nails were like brittle rubber. They would bend, peel, chip, break completely off. So I started with cuticle oil, added in an OPI nail serum, added in ISDN silica serum, and I did see a big improvement. But they would still break, which made me feel like I had to go back to the rubber base gel I was using. I figured it couldn't hurt to try this creme and OMG the results are crazy. It really helped seal the deal for me and now I can wear my nails bare, do yard work, go about my life and they are so strong! In my entire life I have never seen them this way. They really are as hard as hooves! I believe all of the items I use have helped together, but I love the unscented option and appreciate how great my nails look. I'm very glad I found this and highly recommend it!

Great product for weak brittle soft nails!
I’ve been looking for help for my nails for over a year. They kept breaking vertically, splitting, they were what the dermatologist called “soft”. I tried several products with nothing in return. My cousin told me about this product and I thought a cream to strengthen my nails? But I tried it anyways. I am not disappointed at all! My nails are finally getting stronger, they haven’t been breaking or splitting and they look healthy again. I’m exceptionally pleased with this product. It’s been a life saver. I’m so happy to have finally found something that wasn’t a complete waste of money but rather the complete opposite! I’ve been using it in the morning and before bed diligently. A little goes a long way!

Fortalece las uñas y mejora mucho su apariencia
Después de una semana de uso he notado una mejora clara en mis uñas. La crema ayudó a disminuir las grietas y ahora se ven más cuidadas y con mejor apariencia. La textura es un poco espesa y aceitosa, pero se aplica bien y cumple completamente con lo prometido. Me encantó el resultado y definitivamente volvería a comprarla.
