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

Pricey
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.

Excellent for soft nail protection and growth.
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

Yes you do need a bottle of this RIGHT NOW
I swear on my life, there is nothing I recommend to people more than this strengthener as a basecoat. I had been absolutely SUFFERING with nails that would shatter at the tips or have that flap on the side that is just like, whoops, bye! INSTANTLY, even in one coat, this stuff helped. I've finally been able to grow my natural nails out longer than the press-ons I had been stuck under for ages. And they're strong enough to slam in doors, or shred things with them-- like this stuff weaponized the heck out of them! (I mean, not LITERALLY, ofc) Get this stuff. It's cheap, it looks smooth and dries insanely fast. It'll keep your polish on without chipping away and then just do it again after your next mani too. Thrive. You won't regret it!
