## Description

A concentrated treatment of nail-strengthening biotin vitamin B7 that fortifies soft, torn nails and ends peeling and breaking.

Review: MUST BUY! This nail strengthener is THE TRUTH! - This stuff is THE TRUTH! I don't often leave reviews unless I'm seriously blown away by a product or it's shockingly bad lol. I suffer from iron deficiency anemia and had been rehabilitating my once indestructible nails. With this product they're finally getting back to their former glory. Not only does it keep my nails strong but flexible, I find that it keeps my polish on for 14+ DAYS when used as a base coat. After a polish change, I oil my bare nails consistently for a day or so (I like hard as hoof and bliss kiss nail oil or cnd solar, but any deeply penetrating oil should work). Before my next polish change, I moisturize my hands and nails thoroughly, wash my hands with dawn dishsoap to dehydrate and remove the excess oils from nails. Then, I typically apply 2 coats of this as base polish, let dry, followed by two coats of color and a fast dry top coat. It's been several months without any nail breaks!
Review: I would definitely buy it again. - Excellent product. Since I started using this hardener my nails are stronger and no longer break easily. It is easily applied and dries quickly. Highly recommended.

## Questions & Answers

**Q: Does this help whiten your nail**
A: Nail-Aid Biotin neither whiten nor strengthened my nails. 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

### ⭐⭐⭐⭐ Amazing results. So far. Let me explain
*by G***E on September 9, 2024*

So I was desperate because my nails were very thin from acrylics which usually i never have that problem but it was overfilling that hurt them. Anyways when i soaked off my acrylics 2 of my nails split in half as you can see. I had a nail girl tell me that will take months to grow back and i was so upset. I found this product and its been about 2 weeks so actually and its working amazing. I am so happy and thankful I gave it a try. Obviously its not completely healed but it is a lot smaller of a split then it was before i used this. The photo on the left and the left nail is from Aug 26th and then the middle one is the beginning of Sept and the last one on the right was from yesterday. Big difference ! And the right photo is basically the same. The left nail is from Aug 26th and the right one is from yesterday. Still a working process which i knew it wasn't gonna be that fast because of the condition of my nails. I just wanted to show my progress so far. Update 8/24- This is what my nails are looking like now. I can't believe the results
