Most Helpful Positive Review WEAK NAILS? TRY THIS PRODUCT! I have been using the Sally Hansen's Diamond polish products because I had problems growing nails, they split break wont grow due to my MS. Now I apply the clear polish every few days and look at my beautiful nails. People ask me all the time if they are real, Yes all mine!
Most Helpful Critical Review Made my nails worse I bought this a month ago to stop breakage and it actually made my nails worse. I'm going to try another product today.

Cheap. I wouldn't purchase this product again because once it's applied it just peels right off. Doesn't stick on for very long for it to even do it's job.

It's was a great product I really like this product it's like it's made just for me. It's long lasting, last all day usually even on long days. I couldn't think of a way for it to be better. It's completely incomparable to other products quality wise. I'll definitely buy it again

During winter my nails are really brittle. This definitely helped them. I noticed I had less chips and snags in my nails when I had this on
Wanna strengthen your nails Try this 4

Honestly it works pretty good the formula could be adjusted just a touch turns kind of chunky after a few uses in the bottle but other than that it works pretty well it strengthens my nails when they were absolutely falling a part. But I would say to try it maybe they fix the formulas until last time I've used it and you may get a better result than I did 
So Far So Good: Nails Are Responding 4

I have needed extra help for my nails after months of enjoying nail powder manicures, which are terrific but from which nails need a break every once in awhile. This product goes on smoothly, dries fairly quickly, does not discolor, and protects the nail. I am well pleased and will keep using it! Thanks, Sally Hansen!
Protects your nails 5

I made the mistake of getting acrylic nails a while back and while they might be hugely popular, they are just not for me. Once they were removed, the bed of the nails was just in terrible shape and it took a long time to bounce back. Diamond Strength made them look a little more even and helped keep them protected while they recovered. The only thing I didn't like was how fast it got thick and gooey, but overall this is a very good product.
Great Nail Strengther 4

RThis product definitely has a strong smell! However it does do the job has a nice natural shine to it! My nails have always been weak, and I get gel polish on my toes. After continuous use of gel polish, my toes nails became weak and damaged., I noticed significant improvement in about 3 weeks. I gave 4 stars because I prefer a clear bottle so I could see how far in I was dipping the brush how much product was left.

It has helped my nails they aren't as brittle as they were and they are growing better now I can paint my nails and they look smooth and nicer.
good, but not sure it made them stronger 3

I think this treatment help prevent my nails from becoming more brittle/prone to breakage, but I don't think it actually strengthened my current nails. Once the polish is off, your nails revert to the condition they were previously in. I wouldn't buy again, but I'll continue using for the preventative aspect.
The quest continues 4

I am on the search for the best nail strengthener after a medical procedure made my nails and hair super brittle. I honestly hate doing my nails at home, but if it's low maintenance and will help my nails, okay fine.
This is the third Sally Hansen strengthener I've tried, and I'd say jury is still out on which one ultimately is the best, but the diamond strength is nice! With the exception of my pinky finger, as you can see in my photo, you can barely tell where the ANC ends and my natural nail starts. Which is a huge bonus. I also appreciate that there's a bit of shine to this, since I'm using it alone, but could also be used as a base coat. This also dried very quickly, which is important as I'm busy and use my hands a lot. No smudges!!
As far as strength—well, I haven't chipped my nails since my application last night, but my nails are quite short. And I try to use my nails gingerly anyway. But it does feel like they won't immediately break if I were to pry some LEGO pieces apart right now lol!

I love using this to strengthen my nails. Sometimes when I try to grow out my nails they will peel or get caught on clothing and stuff so when I use this I don't have that problem anymore.

My nails grow super long and pretty hard but this helps them from breaking off at my skin. Provides the little extra boost them need. I love using it and will keep buying. Its affordable as well

It was nice color seemed to chip pretty fast. Not sure if it made my nails stronger either. I have used cheaper polishes that lasted longer. This wasn't t he e worst but definitely not the best!

It does on thick. It stays on for a few days. It's not expensive. But not sure if it really works or not. Although I'm not the best with keeping up on painting my nails all the time.

I use this almost every time after i get my nails done. The only time I don't is when i get a fill. The smell isn't my favorite but i don't expect it to smell nice. Also i have a really strong smell so it might just be me being sensitive to strings scents.
