I started using this because I paint my nails slot and I needed something that would strengthen my nails. I like it so far and it seems to do the job well enough. Now 100% sure if this is really working I still have a few nails that chip off every now and then but it's not too bad. Would definitely recommend you try it out for yourself

I love this product. I've been using for my weak nails that break a lot. I have already seen a difference.

Like this product. I tried it on my nails after they started getting weaker and noticed some difference but it wasn't dramatic. They don't break as often but they're not as strong as I'd like them to be

I'm a fan of sephora makeup but this product and other nail products from sephora I don't really like my nails are still brittle after one use it's clumpy and gross but this generally happens with most nail products quickly sinful colors is the only nail product I've found that doesn't.

I really enjoy this product. I do my nails often, and working in a hospital wearing gloves all day can do damage. This treatment keeps my nails from becoming brittle.

This is a fine clear nail polish. I didn't really notice it making my nails any stronger or less likely to break. But it worked as a good base or top coat.

Does this really work?! I've been looking around for many different nail strengthening polishes. My nails are so brittle and weak. I can literally rip a tip of my nail off if I wanted to. I am so deprecate to find something new.

I am already an OPI lover, but I have never used this. I need something that will strengthen my nails & moisturize my nails. My nails grow... But they break as soon as I start getting length. They also become very dry and peel. Quick drying is also important, I need something that I can put on if I'm in a rush and not worry about smudging. Is this product good, if not what product(s) will help my nails?
