Remove old nail polish, if you're wearing any. Use nail polish remover and a cotton ball to wipe each nail clean.
Wash your hands with soap and water to clean thoroughly.
Open the nail strengthener and wipe the brush off on the rim of the bottle to remove excess polish.
Place the brush in the center of your first nail and stroke it gently across the surface from the base of the nail bed to tip.
Move the brush slightly to the left of your first stroke and swipe the polish along the side of the nail. Try to keep inside the nail and away from your skin. Repeat for the other side so that the nail has been completely covered in polish.
Let the nail strengthener air dry. This typically takes about 10 minutes. As a base coat, the nail strengthener can penetrate your nail to seal it and make it stronger. If you like the natural look, leave your nails as they are.
Follow with a coat of your favorite nail polish, if desired, then apply another coat of nail strengthener. As a top coat, the green tea plus bamboo polish provides a hard surface that resists peeling and bonds weak nail layers. Let the top coat dry for about 10 minutes.
