Sally Hansen Advanced Hard as Nails™, Clear Nail Strengthener, Includes Retinol and Nylon, Nourishing

Have used it for decades and it still works to protect my nails with thin coats and last at least a week. I highly recommend this cheap everyday protecting nail polish. Shiny too!

This Sally Hansen Hard as nail literally saved my nails. Thank you for this product. Also it’s very affordable!

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.

This clear nailpolish is the real deal of hard of nails that makes your nails grow. This brand is difficult to find in the stores now, especially the official sally hansen stores but it's a good product and can make your nails nice and hard. Defiantly a 4 out of 5, especially the price. The texture is thin but the coverage and durability is worth it. One or two strokes will do.

Sally Hansen’s Hard As Nails Clear Polish is like a bodyguard for your nails—quiet, strong, and always on duty. Whether you're going polish-free or layering underneath color, it adds that crucial extra boost of strength without fuss. 🔒 Tough-as-Nails Protection: This formula lives up to its name. It reinforces fragile nails, seals cracks, and prevents peeling. Perfect for anyone trying to grow out their nails or recover from gel/acrylic damage. 🌟 Clear & Glossy Finish: Goes on smooth and dries to a transparent, glassy shine that makes bare nails look instantly healthier. It’s the kind of "clean girl" aesthetic that works with literally everything. ⏱️ Quick Dry & Long Wear: Sets fast and wears for days without chipping. Works well solo or as a strong base coat under color. Helps extend the life of your mani without complicating your routine. 👜 Easy, Everyday Essential: Affordable, accessible, and easy to stash in your bag or drawer. It’s the kind of drugstore staple that shows up for you, time after time. 🎀Final Nail Note: If you’re looking for effortless nail care with real results, this polish is a classic for a reason. Simple, strong, and ready to keep your nails looking polished—even when they’re not painted.

The Sally Hansen Advanced Hard as Nails™ Clear Nail Strengthener is an outstanding product for anyone looking to restore, protect, and maintain healthy nails. From the very first use, it provides a smooth, glossy layer that instantly strengthens and protects fragile nails from chipping or breaking. The formula includes Retinol and Nylon, which work together to nourish and reinforce the nail surface, making them more resilient and less prone to peeling. I love how lightweight it feels it dries quickly without leaving any stickiness, and it gives the nails a natural, polished shine that looks neat and professional even without color. Whether used as a base coat or alone, it noticeably improves the appearance and texture of the nails within just a few applications. What truly makes this product stand out is its consistent performance and visible results. With regular use, nails grow stronger and smoother, and the splitting that often happens with daily activities is greatly reduced. It’s perfect for anyone who frequently uses nail polish removers or washes their hands often, as it helps to rebuild the nail’s natural strength. The brush applies evenly, making it easy to get full coverage in just one or two strokes. After a week of use, my nails looked shinier, healthier, and much less brittle. The Sally Hansen Advanced Hard as Nails™ is a must have for maintaining beautiful, strong nails affordable, effective, and reliable. It’s truly one of the best clear nail strengtheners available for everyday nail care.

As other reviewers wrote, this Hard as Nails works as well or better than OPI Nail Envy (which I'd been using the last few years). One coat of Hard as Nails (with nothing else) lasts for 2 or more weeks. No need to add an additional coat every day or two, at least if you have no color polish underneath. I have one nail that is damaged and splits easily so this is mostly to protect that one nail and it works great for that purpose and for protection and shine for the other nails.

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

Funciona 1000% Mis uñas nunca habían sido largas e irrompibles ❤️

Verhard de nagels , komt ook na met wat er over het product geschreven wordt. Tevreden over het product.

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.

I know my nails won't break when I'm wearing two coats of this. Nail polish goes on smoothly over the top
