Made it through an obstacle race!

I have been using diamond strength on and off for months and it works so well for me! However, I never thought about writing a review for it until yesterday. For as long as I can remember my nails have naturally been flimsy and have peeled. After I started using this product all of that stopped. Fur...

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!

I have used this many times over the years when my nails have needed a little help. It strengthens my nails right back up and helps them get back to a strong state.

I really like this nail polish. You only need 2 coats to get full coverage. It's lasted about a week before chipping. Which most nail polish chip after a day or so. I would recommend this to family and friends.

is it gluten free
Asked by chuckie
Official Answer By Sally Hansen - Brand Engage
Hello! Thank you for your interest in our Sally Hansen Diamond Strength Instant Nail Hardener. Gluten is naturally present in wheat, rye, barley, oats, and their crossbred varieties and derivatives. We understand that gluten in cosmetics is a common concern among consumers who have a sensitivity to gluten and those with celiac disease. If you have a gluten sensitivity, please be assured, there is no scientific evidence that gluten in cosmetic products which do not have the potential to be ingested (such as lip products) poses a risk to health. We recognize you may still prefer to choose products that don't include gluten, particularly lip products. To help identify gluten in our products, we have provided you with the full list of ingredients. However, if you suffer from severe celiac disease, we encourage you to review the ingredient list of any new product with your medical professional before general use: Butyl Acetate, Ethyl Acetate, Alcohol Denat, Nitrocellulose, Isopropyl Alcohol, Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer, Triphenyl Phosphate, Trimethyl Pentanyl Diisobutyrate, Sucrose Acetate Isobutyrate, Ethyl Cyanoacrylate, Diamond Powder, Dimethyl Polysiloxane, Etocrylene, Isopropyl Titanium Triisostearate, [May Contain:D&C Violet No. 2] We hope that you give it a try!
