- Apply two coats of the nail strengthener on clean, dry nails.
- Then apply one coat every other day for a week.
- After one week, remove it with a nail polish remover (acetone free), and start the process again.
*Our nail strengthener can also be applied as a base coat to help your nail polish adhere to the natural nail while protecting your nail bed!
- 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.
