- 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.

Great product that helps leave nails harder and stronger after 2 or three coats. The dry time quick is fairly quick. This formula helps reduce chipping and cracks.
Perfect top coat!

Dries fast ..pretty glossy look ....helps me grow nails ...makes them strong and shiny..easy to remove with polish remover also dries quickly..
