For Super strong nails!

a year ago
This diamond strength nail polish is great if you have damaged nail beds from the use of gels or acrylics and just need a little more strength in your nail to keep them from bending. It still gives you a good shine and only takes a few minutes to dry so you can use it on the go or if your in a pinch! I use mine when I need a little more strength and protection after removing my acrylics.

Adds diamond luster and diamond like strength to frail brittle nails.

I am very impressed with Sally Hansen diamond strength nail polish for its high diamond like shine. Nice brush applicator makes it easy to apply and it works great by adding strength to my very thin brittle nails. A repurchase and a high recommend.

This clear coat works well to keep your color nice and strong. It keeps my nails from chipping, and the color stays vibrant. It dries pretty quickly, too. I would recommend it as a clear coat!

Strong nails

I've been using this product for a long time now. I feel like it makes my nails so much stronger, it's transparent so you can't really see it but it does give a gentle shine.

Amazing strength

Omg I love this!! They weren’t lying when they say Diamond Strength! I love painting this on. They feel hard and the lovely little shine it gives is amazing. It only takes 60 seconds to dry providing you don’t paint it on too thick. Better to do it in thinner layers!

Game changer!

This top coat is an absolute game changer if you have thin/weak nails that are prone to splitting. It doesn't take long at all to dry and really leaves a decent strong finish, would recommend this to anyone that uses normal nail polish as extra protection from chips and splits

The Best Sally Hansen Product For Versatility

If you like shine, and lots of it, this Sally Hansen polish is the product to try. As with all Sally Hansen nail polishes, it strengthens your nails very well. I use this one as a base coat, a clear “color” coat, and a top coat as well, if I am desiring ultimate shine. You absolutely cannot go wrong with the Sally Hansen Hard As Nails Diamond Strength! Love, Love, Love it!

Great for brittle nails that won’t grow!

This product is great for my girlies with brittle, thin nails that have a hard time growing. I had issues when I was younger (and sometimes still do) with biting my nails & this polish helps to strengthen them & discourages me from biting.

Been using this for many many years. Love this when my nails are feeling weak or I'm using a polish like a metallic that isn't quite as thick of a formula. Helps it not chip as easily.
