Healthy for you and healthy for the planet.
Our plant based formula is like a nutrient-rich soil from which stronger, healthier nails grow.
Using the latest in cutting edge green science we are proud to present a formula that is made using plant based ingredients with little to no waste by-product.
We use raw, sustainable ingredients including sugar cane, cassava, cotton and corn. Building on our pioneering vegan, cruelty-free, non-toxic formula, we are now the world’s first, nano-particle free nail polish, that’s healthy for people and the planet too.
Sienna is a 100% vegan and cruelty free company with the certifications to prove it. This is core to our values and implemented with everything we do.

My husband bought me the bundle kit for my birthday and after using these products consistently for 5 months, my nails are in the best shape they’ve ever been in. I’ve always had terrible nails - they would snap and break and I’d bite them, but since using Sienna, my nails are strong and long, my friends all think I have acrylics but they’re just my natural nails! It’s actually mind blowing. The colours are stunning too and I love that I can do a polish once a week and the polish actually lasts, doesn’t chip quickly like other brands. Thank you so much Sienna. I officially don’t need to bother with expensive and time-consuming nail salons anymore and still have beautiful long nails ❤️

My nails have never been stronger since using the Sienna Nail Strengthener! Even after I take my polish off my nails are still strong. I have also found my nails are finally growing since using it.

Frequently Asked Questions
We’ve got you covered. Find answers to all questions.
Did you know that a company can be vegan but not cruelty-free? Confusing isn’t it! Cruelty-free refers to not testing on animals, whereas vegan means not including animal or animal by-products within ingredients.
Sienna nail polish is proudly both vegan certified and cruelty-free (woohool!) and is accredited by Peta (Beauty without bunnies program) which are all auditing bodies who verify the high standards we set for ourselves. We created our entire range so that you can have peace of mind that our products are of the highest quality for you and don’t harm our animal friends.
When non-toxic nail polish arrived in the market, the ‘X-free’ branding was used to show customers the number of chemicals a polish is ‘free’ from.
Unfortunately, without a regulatory body for this type of branding it is fast becoming a race to include as much as possible in the ‘x free’ calculation and some brands have started including ingredients that are not commonly found in nail polish. Therefore, we have decided to not label and let our ingredients list do the talking. We go into this in more depth in our 10-free, 12-free nail polish explained blog.
So don’t be fooled by a big ‘x-free’ number. Take a look at each brands formula to ensure you’re getting a true natural and non-toxic nail polish.
Sienna stands strongly by our formula and is proud to be a natural and non-toxic nail polish brand that is the cleanest brand on the market globally.
We have always been free of formaldehyde, dbp, toluene, tosylamide/formaldehyde resin, synthetic camphor, xylene and benzophenone -1. We are also accredited by the safe cosmetics australia (the toxic-free campaign) and our mission is to ensure that our formula supports your health, planet and your manis!
And if you still don’t take our word for it, we are certified by made safe who have analysed every single ingredient and deemed us the cleanest. Simply put, we want you to be able to enjoy luxe, high-quality natural nail polish that’s free of nasties and available in a beautiful range of organic colours. What more could you want?
