- Start with a well prepped nail by using a single coat of either base coat or nail strengthener.
- Next, with your choice of colour, swipe one side of the brush on the inside of the bottle neck to remove excess nail polish.
- Place your brush with the drop of polish at the base of your nail, near the cuticle. Swipe it in a straight line from the base to the tip of the nail.
- Return to the base of the nail and gently swipe to each side of the initial stripe, covering the nail fully.
- Repeat the process on each nail.
- For full coverage apply two to three coats of colour.
- Finish with your choice of glossy or matte top coat.
- Voila! You achieved nail polish glory.

Sienna is a conventional vegan nail polish formula. It offers a cleaner and more natural option compared to other brands.
Glitter has a significant environmental impact, and we stand against that. Microplastics from glitter have been documented to harm marine life, causing seabirds to die of starvation when ingested. Sienna was the first nail polish brand globally to ban glitter from production to address the environmental concerns.
Our nail polish allows both air and water to permeate through the surface. Scientifically tested to ensure osmosis occurs all the way to the nail bed..
Please note that this osmosis is not visible to the naked eye, and commonly used coffee paper saturation tests are not accurate. Osmosis happens through gently permeating the nail polish film..
