Ex-nail biter now!
I’ve bitten my nails for over 30 years, so growing them out has always felt impossible for me. I decided to give Sally Hansen Advanced Hard As Nails Strengthener a try, and I’m honestly so glad I did. As someone completely new to nail care, I needed something simple and effective and this has been exactly that. My nails used to be weak, peeling, and constantly breaking, but after using this, I’ve noticed a real difference. They feel stronger, look healthier, and for the first time ever, I’m actually seeing length! It dries quickly, has a nice subtle shine, and is really easy to apply, even for a beginner like me. I also love that it gives my nails a bit of protection, which has helped me resist the urge to bite them again. It’s not an overnight miracle, but with consistent use, it’s definitely helped me on my nail growth journey. If you’re someone who struggles with nail biting or weak nails like I have, I’d absolutely recommend giving this a go.. you won’t regret it!

Great product!
Great nail hardener! I’m a nurse so I wash my hands all the time. Having grown my nails after biting them for years I found they were very brittle. Having read reviews I thought I’d try this product. I find it excellent. I’ve only been using it for a week and already my nails feel stronger. I recommend this. Good price too.

Strong nails
I've been using Sally Hansen Hard as Nails for a while now, and it’s become a staple in my routine. It applies smoothly without streaks and dries fairly quickly, which is always a plus. My nails definitely feel less prone to breaking when I use it regularly and have a better chance of growing to a nice length (though they do eventually break/split/bend still (it's not a miracle treatment and I probably need more supplements). It’s a solid option if you're looking for a basic, reliable nail treatment that does what it says. Definitely worth picking up if you want to try something that works without spending a lot (I have found it is often cheaper on Amazon than in Boots)

Keeps nails strong
This stuff is excellent! I have really brittle nails, and this stuff really helps stop them from breaking. Bought some for my mum and she’s really impressed with it too. Would highly recommend for anyone looking for stronger nails

It works! Hard as nails!
I bought this one week ago. I am a very practical person and do a lot with my hands at work and at home which often causes my nails to break before they have the chance to grow. I decided I wanted my nails to grow and so looked for solutions, which led me to this product. Just one week later, I have noticed a massive difference....My nails are actually growing! Thank you!

I decided on day to actually learn what you are supposed to do with your nails correctly and decided to not just buy stuff from the dollar store anymore. That lead me down a deep rabbit hole about which products where best, the types of nail polish, undercoats, top-coats, gels, hardeners and AHHHhhhh! Suffice it to say I am more familiar and comfortable building a fire in my wood stove or fixing things around the house. I am also... kinda of cheap because I have brilliant children who will want to go to college someday and other things I am always saving up for. So, with all of that in mind I started the journey towards finding high quality but not too expensive clear coats. This was one of the 3 I bought and I am absolutely impressed! It lasts for weeks. I am pretty rough on my nails but this stuff just lasted and continued being shiny, smooth and keeping my nails happy. One thing I did notice which is probably just because I have never used anything like this before was that instead of breaking off in one big break like my nails normally do, with this on they flaked in layers or broke in smaller ways just at the tips. It didn't seem like it caused any negative issues because nails will always break eventually, but that was a change in how they reacted I noticed. So for the price and what it is the quality is there. It isn't too thick which is nice, and it dries quickly. Can't ask for much more for a basic hardener/clear coat.

Grossartiger Nagelhärter, ich hatte mir durch Nagelstudio u zu intensivem Abfeilen meine Fussnägel versauen lassen. Mit dem Härter schon nach kürzester Zeit eine merkliche Veränderung u nun alles wieder schick. Ich habe immer nach 3-4 Tagen den Lack abgenommen u neu aufgetragen. Werde ihn weiter nutzen.
