OPI Nail Envy Strength + Color 

OPI Color + Strength, the original OPI treatment with a vegan formula, protects natural nails. For long-lasting shine and care, available in a variety of classic OPI colors.

1. Thoroughly clean your unpolished nails to remove any dirt and oils.
2. Apply a first coat of OPI Big Apple Red nail polish to each nail and let it dry. Repeat the process with a second coat.
3. Apply another coat daily to strengthen your nails and protect them from chipping.
4. On the 7th day, check the condition of your nails. If necessary, you can carefully remove the layers and start the process again to ensure continuous care.
5. For professional use in the salon: Use the nail polish between professional treatments—no base coat required.
