Unfortunately, I purchased two bottles of this product. Initially, it appeared my nails were getting stronger. But not only did they begin to break again, but the condition of my nails also worsened. Moreover, the contents of this product are not listed, so you are not aware of what you are putting on your nails. The merchant does offer a return policy but the shipping cost that the merchant require is either equal or greater than the Nail-Aid product. As such, you are stuck with a product that does not live up to your expectations nor their claim of strengthening your nail. **Q: Which one to buy for vertical split nails?** A: I purchased both and wish I only purchased the Keratin because the Biotin polish peeled right off my nail the following day. I’ve never seen anything like that before and it was applied over their Keratin polish so either it was so thick that it didn’t lay down flat or it’s not compatible with their own Keratin nail strengthener. The Keratin nail strengthener was nicer and laid down flat on the nail. I’m very disappointed in this Biotin polish and I’ve used several brands (including Sally Hanson) which never peeled off in a solid layer as if it was nail resistant like this did. **Q: which is better for nails, keratin or biotin?** A: If your nails are damaged, it’s better biotin **Q: Is there suppose to be a brush on the end of the applicator?** A: Yes it has a brush on the end ## Customer Reviews ### ⭐⭐⭐⭐⭐ highly recommend *by on Reviewed in the United Kingdom 13 July 2026* fantastic productchanged my nails completelyI bought both this one and the sapphire strength one and use them alternate dayscould not be happierhighly recommend ### ⭐⭐⭐⭐⭐ Stronger nails *by on Reviewed in the United Kingdom 26 May 2026* Good productMy nails are definitely stronger ### ⭐⭐⭐⭐ Great product *by on Reviewed in the United Kingdom 19 March 2026* I bought this because it isn’t tested on animals as I do with all of my make up also.If these companies can be cruelty free, why can’t all of the other companies?The product is great, the only reason I haven’t given it five stars is I can’t understand why the brush is so short. It makes it harder to get the nail varnish out. Apart from that it’s great. ## Frequently Bought Together - Nail-Aid Biotin Ultimate Strength - Nail Treatment & Strengthener - Clear, 0.55 Fl Oz (08873) - Nail-Aid Keratin 3 Day Growth Nail Treatment & Strengthener, Clear, 0.55 Fl Oz - Onyx Professional Hard as Hoof Nail Strengthening Cream with Coconut Scent, Nail Growth & Conditioning Cuticle Cream Stops Splits, Chips, Cracks & Strengthens Nails, 1 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/83042964-biotin-ultimate-strength-vitamin-b7-nail-polish-by-nail-aid](https://www.desertcart.co.za/products/83042964-biotin-ultimate-strength-vitamin-b7-nail-polish-by-nail-aid) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-27*
