- Q
is it gluten free
- Asked by chuckie
- Official Answer By Sally Hansen - BEHello! 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!

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...

Holy Grail
My nails are naturally pretty soft/fragile and I'm not exactly easy on my hands. This stuff is amazing at actually hardening my nails and keeping them sturdy so I can actually grow them long enough to actually have a free edge. Works great and lasts forever alone or under colored polish. Will always repurchase.
Definitely Diamond Strength!

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.
