Nails.INC Gimme Strength Nail Treatment, Restoring Nail Strengthener with Vegan Collagen, Shimmering Nail Highlighter, Cruelty Free, Vegan

I can't say if this really helped harden my nails, because I take daily biotin to help my nails as well, but I do love this formula. It's nice and shiny, dries pretty fast, and doesn't smudge on my nails like some other brands (looking at you OPI >_>). I'll definitely be buying and trying more from this brand.

Great nail strengthener. It’s the second time I have used this on my nails. My nails grew lovely and strong and I was able to have a manicure and polish using my own nails. Would recommend highly.

Good item & bargain on prime day

I love nails inc products. After having gel nails on my nails underneath were dry and cracked. Putting this on top and then the top coat helped keep my nails from breaking/splitting while I grew them out naturally again. Highly recommend!

Yes would buy again and recommend to others

Nails Inc need I say more

Only tried once so far, but seems to do the job

Ok so didn’t realise it had a faint shimmer but really liked it! It’s not too obvious unless you get a close look at it. Needed something asap for my nails as 4 were broken in the corners an going on holiday soon. They dried super quick and withstood me doing the washing up and changing baby within a hour of application. My nails don’t feel heavy which i sometimes get the feeling with strengthening nail treatments. Can already feel my nails feeling better. I am going to cut my nails short anyway so hopefully I won’t have any breakages. All in good a reliable nails inc product, will point out the packaging tape was open - and felt the big box was unnecessary for such a tiny item. Really like Nails inc kale polish so had good hopes this one and it delivered!
