I thought this product was good. I wouldn’t say my favorite. But I liked it enough to continue using it. It did a fair job at strengthening my nails. It is an affordable product the does work. So I’d say for a drug store product it is worth buying.

It's okay but definitely not the best!

a year ago
Not amazing but not horrible. It works but takes multiple coats over a long period of time to be effective. I'm honestly not sure if it was just the number of accumulated coats or if it actually strengthened my nails.

Nice product

Used years ago and never repurchased. It’s a decent coat for the price point but I tend not to do my nails at home any more. It did add nice shine to the color.

Good for price

a year ago
This product is good for the money, but I don’t think it’s noticeably strengthening. I find it to be super shiny and easy to remove, but it chips a lot and then just looks kind of bad. It does dry super quick, so I use it when I need a quick nail pick me up.

We appreciate you taking the time to try our Diamond Strength Hardener. Even though this product is super shiny and easy to remove, we are sorry to hear it chips a lot and does not noticeably strengthen your nails. Your feedback is important to us, and we will be sure to share your comments with the appropriate teams. To ensure proper application and to help nail polish last longer, we have provided some helpful tips below: -Before applying nail polish, we recommend wiping your nails with nail polish remover and then washing your hands with warm water to remove excess oils and dirt. -Don't buff your nails as this can make the nail surface too smooth for the polish to take hold. -After applying nail polish, allow enough time for it to dry and set. If possible, avoid hot baths and heavy housework for 12 -24 hours after doing your nails. Detergents and household cleaners can make nail polish wear off quickly. If you would like to try a different product, we suggest trying our Miracle Nail Thickener. When your nails need protection against bending and breaking, our exclusive Calcium and Ceramic Gel formula builds a hard shield. Ridges and imperfections are filled in, for thicker, harder, stronger nails. We hope you give it a try! If you have any other questions or comments, please let us know. You can give us a call at 1-800-953-5080 or send an email via the Contact Us page on our website. We will be more than happy to help you out further.

A little thick but good

a year ago
Still pretty nice and shiny, but this one is a little thicker than I would like and can sometimes cause a vaguely lumpy finish. I like the longer brush versus other brands, and the bottle is actually super sturdy which is nice if you're clumsy

Hi there! We appreciate you taking the time to try out our Sally Hansen Diamond Strength Base and Top Coat. We're happy to hear that you are enjoying the shiny finish but we never want to hear that it does not apply smoothly and has become thick. We are happy to help. If the polish is too thick in the bottle, try thinning it by adding 1 or 2 drops of acetone-free nail polish remover. After applying, allow enough time for it to dry and set before applying a second coat. Your loyalty to Sally Hansen is highly valued, and we encourage you to contact us with any questions. Please feel free to give us a call at 1-800-953-5080, or you can send us an email through the Contact Us page on our website. We will be more than happy to assist you further.

Could have been a 4-5

2 years ago
Overall it is a good top coat. The packaging gave me some issues. Maybe it was just a defective bottle but I think it’s important to note. The clear polish on the inside would ooze out a little and dry, making it hard for me to unscrew the lid the next time I needed it.

Longer/Stronger nails

This nail product definitely strengthens your nails and helps them to grow longer too. When I put it on I feel like I can feel the product going into my nails, which is weird but not painful.

Thin Nails

I have tried this product in the hope of finally being able to grow my nails. They are terribly thin and break easily. Caused by many years of nail biting. Unfortunately, this product didn't help my nails, but did keep them protected longer than usual.

I think this product is ok.. I wouldnt say it did too much in my opinion. I bought it once I probably wouldn't buy it again . I have been happy with Sally in the past but this product for me was just a little underwhelming. Im sure someone else out there might love it but for me it's just a miss on this one.

I want to give it more stars but…

3 years ago
Well, I learned after using this for years and gone thru at least 5 bottles, that it horribly discolors and oxidizes. It yellows so bad, it goes from silver glitter in a clear suspension to a dull light yellowed brassy tone in a yellowed suspension. I wish they’d add a UV protectant or something to prevent this. Otherwise it is beautiful and a great topper.

Sally Hansen Diamond Strength Nail Colour 13.3ml-215 Something Borrowed by Sally Hansen I was not as impressed as I thought I would be. I am a repeat user. The tips of my nails chipped on the 2and day. I would like it to have more gardener in it. There prices were high for the wear I got. Maybe for someone who doesn't use their fingertips for a living. I give this 3 stars.

It's okay not the best. I used the diamond strength for about a month continously, and didn't see any amazing results. It's easy to apply and use, you diffently need to apply 2 or 3 coats. Diffently not for people with super long nails that are looking for strengthening polish. I would probably not buy this again.

I haven't used this product much. I bought it because my nails have become more brittle ever since I started to paint them more. I have used this product about 2 times and I haven't seen a difference. This may be because I haven't used it enough. I am not sure.
