Good product. Felt my nails stronger within a week. In comparison with other brands, this one really delivers. The company needs more inventory. Usually there is none of their products available. Definitely would buy again

It works
3 years ago
This is a pretty good product. I have really brittle nails sometimes, and this definitely helps a lot. I like to use it in winter when my nails are cracking off a lot, especially with all my hand washing now during the pandemic. This stuff keeps me from constantly having hangnails!

I always had trouble growing my nails because they would always crack and break. I tried this one and let me tell you, I was amazed! And I've tried a ton of others. My nails grew so long and strong and it didn't take near as long as others did o teach my desired length! You've got to try and see for yourself!

Applies nicely. Strengths my nails and prevents peeling. Good value for your money. Sold at many stores and easy to find. I don’t like to use this product immediately before painting my nails with polish, but rather use this the night before painting my nails. Sally Hansen Diamond Strength®

Trust in Sally Hansen
3 years ago
Sally Hansen is a trusted brand. I have confidence that any product I purchase from this brand will work as suggested and this product was no different. I use this every day to strengthen my weak nails. I am constantly in and out of the sea as I work as a dive instructor and this adversely effects the condition of my nails. A quick coat of the diamond strength really does offer that layer of protection I need against the sun and salt water.

This stuff is wonderful for strengthening my nails. It’s easy to apply because it’s not super thin like some similar products are. I keep it on hand.

This does a great job strengthening your nails. Quick to apply and easy to use. This is one of the pricier nail strength products at the drugstore, but worth it in my opinion

Sally Hansen Diamond Strength helps my nails. I have tried several different strengtheners. Sally Hansen Diamond Strength Instant Nail Strengthener has worked much better and, at least for me, creates a tougher nail surface.

GREAT TOP COAT

I have been using this for years. Its a fantastic top coat. It keeps your mani to stay put for a good week or more and keeps your nails strong. You can also use on bare nails as a strengthener. Sally Hansen Diamond Strength gives your nail a super shinny glow.

Good Stuff

I dont take great care of my nails. I do a lot of painting and crafting. Nails are usually coated with paint or glue. When I can be bothered using this consistently it really does improve the state of my nails. Just wish I was a little more disciplined.

We would use it all the time when we were younger and would definitely help nails to not be so brittle, especially after long nail polish use! Sally nail products are definitely a must use! I will always recommend them fist!

This clear polish is great. It hardens the nail and has an easy application. It lasts a long time and is hard to chip. Reasonably priced.

This product helps my nails from breaking as much. I tend to have thin and brittle nails but work with my hands a lot. Using this product seems to improve things so I have chips less often.
