Biotin Ultimate Strength, Clear, 2PCs

I swear on my life, there is nothing I recommend to people more than this strengthener as a basecoat. I had been absolutely SUFFERING with nails that would shatter at the tips or have that flap on the side that is just like, whoops, bye! INSTANTLY, even in one coat, this stuff helped. I've finally been able to grow my natural nails out longer than the press-ons I had been stuck under for ages. And they're strong enough to slam in doors, or shred things with them-- like this stuff weaponized the heck out of them! (I mean, not LITERALLY, ofc) Get this stuff. It's cheap, it looks smooth and dries insanely fast. It'll keep your polish on without chipping away and then just do it again after your next mani too. Thrive. You won't regret it!

I absolutely love the Nail-Aid Biotin Ultimate Strength Nail Strengthener! My nails have been much stronger and healthier-looking since I started using it. I especially like that it contains Biotin (Vitamin B7), which makes it feel like I’m giving my nails extra care while helping protect them from breaking and splitting. I use this along with the Nail-Aid 3 Day Growth Nail Strengthener, and I really like the combination. I use the Biotin Ultimate Strength as part of my nail-care routine and then use the 3 Day Growth polish to help encourage longer-looking nails. Since using both, I’ve noticed a real difference in the strength and appearance of my nails, and I can actually see them growing! If you're trying to grow your nails while keeping them strong, I definitely recommend giving these two Nail-Aid products a try

I love this product and it's not my first time purchasing it, the only reason I am taking one star away is the bottle was almost broken at the screw on part when I received it. I am more apt to think it would have happened by the machine and sometimes those things happen but it will make using it a bit harder so I will just need to use caution while I am opening and closing the bottle. The screw on just seems to be rough and won't work unless I force it closed, which leads me to think that it probably was a machine error, but since this has never happened before, I only took off one star. The product itself is great so I keep buying it as it does help to keep my nails strong and help with growth. I just apply one coat to my nails before applying polish or wraps then use a top coat to finish or this has even been used as a top coat if none other is available. If you have weak or brittle nails, it really does help and give it a few days adding a coat to your nails each day, or every other day which ever works for you.

I bought this after wearing acrylic nails for months, and my natural nails were left weak and damaged. After using it consistently, I noticed they felt much stronger and finally started growing again without breaking so easily. They also look healthier and have a nice natural shine. I’m really happy with the results and will definitely keep using it.

This is the best nail strengthener! I’ve been using it for years, even through chemo when my nails got thin this nail strengthener kept them from peeling and cracking. I’ve tried others but nothing is as good as this one, imo! You can’t beat the price! It’d be great if they made it in colors. Until then I will keep my nails clear!

Worked gone but got gooey fast! Half the bottle was trashed!

This nail fix I call it. Works great ! Nails are growing for sure. Then once in awhile one nail breaks and have to start all over but the trick is to clean you out hands good before putting the polish on otherwise it won't stay on good. It's better than many others. ! My right hand doesn't do good as much as my other hand. Mostly because I use my right hand more. But worth buying.

I love this stuff, but I primarily use it in a different way than the product is advertised - I use it as a top coat on top of my color and the polish lasts WAY longer. It really minimizes all chipping, and I won’t get tip wear if this is on top until 5-6 days into a manicure, but tip wear is guaranteed within a day if I don’t use it. I also like to use it a few days into a manicure to make it look shiny and plump again. I don’t use hardeners directly on my nails often, they’re pretty hard on their own usually, but I’ve done that with this a couple times if they get damaged and could tell the difference in strength for sure.

جربته ترا مو مره واو يعني بستمر واشوف

No cumple con lo que dice, 2 semanas usándolo y las uñas están igual ,ni endurece ni crecen más fuerte Para mi todo un engaño

It is as good as Mavala blue water. Very good product, really helped for strengthen and grow my nails.

I have very brittle soft nails that don’t grow very well. I ordered 2 of the bottles of Nail Aid Biotin Ultimate Strength nail treatment and as this is the second day I have used it I don’t have a real sense of trying it out. It goes on very well and the 2 coats did seem to have made my nails less bendable. The nails have a high gloss which looks great and I have to put a second application of 2 coats on in 1 day after using a polish remover and cleaning the nails. This is the first time I have felt comfortable that this product will work as no other nail strengtheners have done so.

Fantastic product, noticeable difference during and after use. Very strong coating when using it and strengthens the nail underneath so you develop naturally stronger nails the more you use it. Easy to use and cant really fault it. One of the best ones of its kind that I've tried for an affordable price
