Great product.
Great product helped my nails recover fully after having 4 months of acrylic nails which ruined them. This repaired and helped my nails grow delighted!

It really helped strengthen
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

Peels often
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.

Definitely see a difference
Amazing nail strengthener, I’m on warfarin so my nails are extremely thin and brittle but this has helped so much, still no nail growth but definitely stronger so patiently waiting. You can definitely see a difference 😁definitely recommend.

No complaints
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

So impressed!
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 🙂
