Nail-Aid Biotin Ultimate Strength Vitamin B7 Nail Polish by Nail-Aid

fantastic productchanged my nails completelyI bought both this one and the sapphire strength one and use them alternate dayscould not be happierhighly recommend

Good productMy nails are definitely stronger

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.

I do think this product is a bit pricey for what it does. I've been using it as per instructions, and can't say I've seen much change to my nails. I do think they are a little stronger but still brittle. However, everyone's nails are different and this may work better for others.

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

Ok... So I messed my nails up with gels, biab and not getting them properly taken off. My nails were so thin and weak... Disaster! So scrolled through amazon and found this. I bought it. I used it as instructed pretty intensely at first, then less so after about 2 months. I'm probably 5 or so months down the line and a lot of the damage has grown out now and my nails are growing and are stronger. I think this really helped me. I could certainly feel after I applied a couple of coats that my nails felt stronger, when they were dare I could literally bend them but with this on it was stronger and gave more protection. I would recommend this to anyone suffering with nail weakness

I wasn’t impressed. My nails were breaking a lot more often. I prefer the Nail-aid keratin.

Good nail strengthening, fast deliveries

جربته ترا مو مره واو يعني بستمر واشوف

I have purchased this nail strengthener several times, and it has become one of my favorite nail care products. It dries quickly, is easy to apply, and leaves a smooth, clear finish that works well on its own or as a base coat. With consistent use, I've noticed that my nails feel stronger and are less likely to peel or break. It also helps them grow longer while maintaining a healthier appearance. Overall, this is a product I continue to repurchase because it delivers reliable results. If you're looking for an effective nail strengthener for weak or brittle nails, I highly recommend giving this one a try.

No cumple con lo que dice, 2 semanas usándolo y las uñas están igual ,ni endurece ni crecen más fuertePara 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.
