Biotin Ultimate Strength - Nail Treatment & Strengthener - Clear, 0.55 Fl Oz (08873)

I’ve been using this nail treatment for a while now, and I can honestly say it works really well. My nails feel stronger and don’t break as easily as before. I also noticed they look healthier and smoother overall. It’s easy to apply and dries quickly, which I like because it doesn’t take extra time out of my routine. I’ve tried a few similar products before, but this one has given me better results. I’m really happy with it and would definitely buy it again.

I’ve been using this regularly and noticed my nails feel stronger and less prone to breaking. It goes on smoothly and dries quickly, so it’s easy to include in a routine. With consistent use, my nails started looking healthier and growing a bit better. It’s a simple product, but it actually makes a difference over time. Great option if you struggle with weak or brittle nails.

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

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!

I really don’t review products often. However, I really had to for this one. I’ve had gel nails for well over 5 years with no breaks. I finally stopped doing them in February. My nails were obviously damaged and kept breaking as soon as they started to grow past my finger tips. I figured I’d give this a try since reviews were promising. I followed the directions and applied every 3 or so days. I did 2 thin coats (dries super fast) and I did a coat of instant dry top coat (Sally Hansen). My nails are much stronger, look healthier, and are growing like crazy! Highly recommend.

Update: I'm now a little more than halfway through the bottle and it has gotten so thick that it's impossible to brush it on smoothly, no matter what I do. It's just... Gloopy. Plus, I've been really struggling to pick up enough of it on the brush because the brush only reaches halfway down the bottle even with the lid completely screwed on. I remember seeing another reviewer mention this but I thought to myself at the time that I would never get that far into the bottle, but here I am a few months later, probably because it goes on so dang thick! Unsurprisingly, this gloopiness certainly does not help with the extra slow drying time. I now have an alternate option on the way and it can't get here soon enough! Original review: every time I apply this stuff it takes forever to dry and still remains tacky for an hour or more afterwards. I've made sure to keep the coats as thin as possible but that doesn't seem to matter. It's especially difficult to apply 2 coats as instructed when starting with bare nails because I have to wait so long in between them. However, some people say that this polish dries really quickly for them, so I'm wondering if not all of the batches of polish are the same. Beyond that, I do like how glossy this polish is and how wide the brush is. Since I use this by itself it does take a couple of coats before you can really tell that there's polish on my nails though.

Works well i use daily and once week remove it and start over . I have noticed my nails have gotten stronger and have grown super fast

My nails were severely brittle, peeling, and cracking after I was anemic. I tried many nail products and this one was the only one that helped. It felt like it made them stronger and also gave an instant protective coating. Gives nails a nice shine too.

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

The Aid biotin ultimate has strength my nails .as they were very brittle and weak .

I have the weakest thin nails, this is the only product I have found over 20 years that actually strengthens my nails.

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
