The Onyx Professional Hard as Hoof Nail Strengthening Cream is designed to help users with thin, brittle, soft, or fragile nails. Infused with vitamins, minerals, and emollients, it aims to strengthen and condition both nails and cuticles. Key natural ingredients include calcium, jojoba oil, and various vitamins, making it a good choice for those who prefer products without harsh chemicals.

Its quick absorption rate ensures that it doesn't leave a greasy residue, which is a plus for everyday use.

Its small size (1 oz) makes it easy to carry, but might not last long with frequent use.

The product is also trusted and recognized within the market, with over 25 years of history. However, the frequent application required might be a drawback for those with busy schedules or who prefer a more hands-off approach. Additionally, it’s recommended to conduct a patch test first to avoid any potential allergic reactions. This product is particularly beneficial for those looking to repair damage from gel or acrylic nails and is suitable for various nail types. Notably, it helps prevent nail splits, chips, peels, and cracks. If you’re seeking a trusted and natural-based nail strengthening and growth solution, this cream is a solid option, provided you’re okay with the application frequency.

Its formula is free of formaldehyde, making it safer and less harsh compared to some other nail treatments. The product applies like a clear polish in a serum form and absorbs quickly, creating a protective layer that strengthens nails and smooths cuticles.

It promises noticeable results in about 5 days, reducing brittleness and protecting nails against splitting, cracking, and tearing for up to 10 days.
