Advanced Hard as Nails Strengthener, 13.3ml (Pack of 1)

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!

Keeps my nails strong and shiny. I wear for work.

I started using this at the start of 2020 and it's made a massive difference to my horribly weak and damaged nails. After many years of getting my nails done professionally, I suddenly developed a nasty allergic reaction to gel nail polish so I had re-think what I could do with my nails. I also noticed that my natural nails were in a bit of a state too. They were very weak and brittle and never seemed to grow without splitting. I just assumed that I had "bad" nails or needed more calcium or something. Around this time the pandemic also kicked off so I couldn't see anyone to get my nails done professionally anyway, and I thought this might be a good time to give my nails a break. I'd never used a nail hardener before and I thought I'd give this one a try. It's a good price on Amazon and considering all the shops were closed, I didn't have a lot of options! It took a couple of months but I started to notice a massive improvement in my nails...they grew!!!!! For what seemed like the first time in ages, my nails actually grew to a decent length. They stopped splitting too. I paint one coat on and then let it dry completely before doing another coat. The formula of this polish is kind of gloopy and has a strong smell but it applies evenly enough. It doesn't peel off after a day either some like clear nail polish tends to either. Overall, I'm massively impressed with this! My nails have improved so much since I started using it. They don't split so much and are actually much thicker too. Now, I'm not implying that this nail hardener is some kind of miracle but it has most definitely helped with my damaged nails. I should point out that what's helped restore my nails is most likely a combination of 1) being furloughed from work due to C19 for a few months and not typing as much, and therefore not using my nails as much as I was before 2) taking more vitamins like vitamin D 3) no gel nails (they really weaken your natural nails and can cause allergies) I think gels and acrylics are very bad for your natural nails. Overall, I highly recommend this. It's worked a treat for me and my nails were in a terrible state. I've been using this for over a year now and my nails have never looked better. I now have to actually trim my nails because they get too long! Never thought I'd ever say that! I no longer get gel nails from a salon either which has also helped to improve my nails A LOT too. Give this a try. It's not a miracle worker by any means, but I think it can help significantly. It's also nice to use as a base coat under regular polish.

I can"t live without this nail protector, tried so many other brands over the years ,but always keep coming back to this one. My only gripe with this varnish is that once the bottle is opened the contents only have a very short lifespan, generally having to throw away half a bottle of varnish. This varnish helps to protect my weak, ridged nails helping to promote a little growth, making my nails look nicer.

I find this product excellent. It doesn't chip easily, looks good on my nails. Would recommend

Very good

Ok so, getting a good quality nail hardener in 2025, you would think should be easy right? Especially when it has the name 'Sally Hansen' on the bottle - a name known for good products. Sadly, I have found this to be lacking in performance and expectations. It has been demoted to a base or top coat. And my 'paper-nail' remains paper like....whilst I try and find something that works.

Great product and quality

I like plain nails but want them to be healthier and look neat and nice so have been using this product for years. I'm glad I found it here

De varios que he probado fue el único que realmente hizo que no se me rompan las uñas! Lo recomiendo!!!

I've tried nail strengtheners in the past, but they never worked for me. My nails are very fragile, brittle, and soft; those are their characteristics. I decided to try this product, and I'm very surprised. My nails are growing stronger, a little thicker, and they don't break easily. I've been using the product for a month now, and I've only used half of it. I put on three coats, and they last four days. I remove them and reapply the product. I also use it as a base for my pedicure. It's simply wonderful because I've never had long nails before, and now they're growing stronger! Girls, I recommend it! You must have it! I want to buy more nail polishes from the same brand. I want to use these strengtheners forever.

Useless product. This is only a clear nail polish that you can use as a base. Does not strengthen your nails.

Considering I trade rent for cooking and cleaning, my hands are in and out of hot water all day, which has contributed to the demise of my nails. I tried nail strengthening creams which seemed to work initially but then stopped. In desperation I gave this a try and within 2 weeks saw a drastic improvement. I realize now, what makes this so great is the coating over my nails is what protects them from the damage of so much soapy water. Now they are much healthier and stronger, and I love the shiny gloss which also makes them look so much better. This is a keeper for sure, and if you have weak nails which are prone to splitting and breaking, give this a try. So much more economical than those expensive creams, and sure to last a long time.
