Diamond Strength Instant Nail Hardener

Diamond Strength Hardener is saving my nails after the damage from a salon SNS manicure!

I have been using it for 2 weeks and I am very impressed. I highly recommend this to keep your nails from breaking and chipping

I've used the Diamond strength polish for years. I wash my hands really well using a nail brush. Then I rub alcohol with a cotton ball, pad or toliet paper. Then I put the polish on length wise. Next day, I wipe with alcohol and apply the polish side ways. Next day length again, day after that sideways. 5th day length again. 6th day, remove all the polish. Leave nails bare until the 7th day then start again. My routine works great with the Diamond strength.

Easy to apply. seems to dry very quickly. doesn’t chip, and gives a good shine also easy to remove. Clear in colour. Can also find on offer in some stores

Sally Hansen Diamond Strength nail polish is great if you have brittle nails. The application of this polish is effortless. It takes very little time to dry. Unlike many other nail polishes I have tried the scent is not that strong so if you are sensitive to the strong smell of nail polish you should give this a try. It has made my nails much stronger than they used to be. The best thing is the price. This polish is so affordable you can do your nails at home instead of going to a crowded salon and get a great result. All of the women in my family use Diamond Strength. I would recommend this product to any looking for a way to strengthen their nails.

As a finger style guitarist, this is the best I’ve found so far to keep my nails intact through rigorous playing. Only wish there was a non glossy option.

This product is great as a base coat But I was wondering if I can also apply it over nail polish

This is the best nail hardener I have found so far. Protects my very weak and split nails. Better than the “Hard as nails”. My only gripe would be the brush which is very narrow. In 10 min is all drying. Is so shiny and very easy to remove it.
