NAIL-AID Biotin Ultimate Strength, Clear, 0.55 Fluid Ounce

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

Was very bad for my nails! It literally destroyed them and made them way worse

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

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