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 fuerte Para mi todo un engaño

Buenisimo!! Ni lo duden. Es lo mejor que he probado

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
