Biotin Ultimate Strength, .55 fl oz

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

Did exactly what it said it would. Helps to protect my and strengthen them

I have soft bendy nails that do not grow well. This treatment makes them stronger and helps to grow. When I don’t use it my nails don’t grown and they remain soft/easy to peel

Find it peels after couple of days so seem to be constantly applying. Seems to make no difference in my nail strength or length as of yet.

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

Wasn't effective, peeled off easily

Wow! I'm so impressed, even after the first application! I've tried so many nail products in the past to try & strengthen my nails but none have worked as well as this product. I'm so hopeful that in time my nails will be very hard, without any bend. Got it on subscribe now, it's so good! One very happy customer 🙂

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.

جربته ترا مو مره واو يعني بستمر واشوف

This product really works. My brittle nails are growing and do not break. This polish actually fortifies the nails from the inside out because after using it for a while, my nails are still strong and don’t break even when I have no polish on them.

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

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.

Excelente prodcuto
