Sally Hansen Diamond Strength Nail Hardener 45095 Clear, 0.45 Fl Oz, Pack of 1

I thought my once-strong nails were a victim of my age, but it turns out that if I use Diamond Strength and take a little more care with water and detergent, I can grow my nails just as well as when I was young. It looks nice, too.This is the only product, whether drugstore or stupidly expensive, that clearly improves the quality and strength of my nails and protects them more than I deserve, given the way I forget to use gloves for cleaning. There's a big difference in my nails when I use it vs not.It goes on easily, despite the uniformly terrible quality of the brushes in Sally Hansen products. It dries very fast, and doesn't chip -- in tends to eventually wear off the tips.I have pretty significant ridges and three coats makes them invisible, and really protects my nails, too. But even a single coat really improves the look of my nails.

IT WORKS!!! I use this faithfully. I've used other expensive brands and they don't compare. My nails look great for at least 10 days and sometimes longer. My nails and the polish become super strong and durable. A smooth strong base coat.

I like this a lot. It is hard and durable and excellent for a top or under at depending on your needs. In example, i.e., Stronger nails or stronger coat. Very good stuff. The bottle cap is kind of slick.

My nails bend very easily, so I started using this. It works miracles for bendy nails. But you need to be careful with not putting a thick layer on. The white part of my pinky nail just crumbled off last night. It's a stub now. I think the problem is I start with my pinky nails so I have a lot of the product on those nails compared to the larger nails. I have heard on numerous occasions that using this product CAN cause brittle crumbly nails. So I'll start using it more carefully, not using as much on my smaller nails. My other nails seem fine though. They still bend some and are not brittle. So overall I think this is a very good product if you have very bendable thin weak nails.Here is how you are supposed to use it (from the Sally Hansen UK website as the US version of the site does not give directions)...How to use:-Shake gently. Apply one coat to clean, dry, bare nails. Let dry.-For extra protection apply a second coat, or use as a strengthening base coat.-Try using it as a 7 day treatment:-Day 1:-Apply 1-2 thin coats to dry, clean, bare nails, apply nail polish if desired.-Day 3:-Apply a further thin coat over the existing nail treatment / colour.-Day 6:-Remove all products from nails (using Acetone Free Nail Polish Remover - as this will dry out your nails the least) and leave bare for 24 hours.-Day 7:-You may begin the treatment again. Repeat usage will give you the results you desire so make sure you stick at it.

lower odor - hoping it hardens better than $$$ others - will update soonUpdate: it IS helping breakage, doesnt chip much either..it IS drying strong/ hard!!!!!!!!!!I wish bottle was see thru - hard to know polish level.

Nails seem to chip or break less. I like it being clear and natural.

Not as hard as nails as described. The polish easily washes off during rehular hand washing. I'm disappointed with this purchase.

It helped my nails not to break easily.It hardened my nails for sure.
