OPI Start To Finish 3-in-1 Treatment with Vitamin A & E - #NTT70

Q: Why should I use cuticle oil, and how often?

Cuticle oils like OPI Nail and Cuticle Oil To Go help keep nails flexible, hydrated, and resistant to breakage. Apply daily to condition the nail bed and enhance the longevity of your polish or gel manicures.

Q: How do OPI nail cleansers help before applying polish or gel?

OPI cleansers such as N.A.S. 99 Nail Cleansing Solution or Expert Touch Lacquer Remover eliminate oils, residue, and moisture from the nail plate. This ensures stronger adhesion, helping your polish or GelColor last longer without lifting.

Q: Can I mix and match OPI prep and care products with other brands?

You can mix and match prep and care products from different brands. However, OPI recommends using their system together to ensure the best performance, adhesion, and wear results.

Q: What OPI essentials should everyone have for at-home manicures?

A cleanser, remover, high-quality file, and cuticle oil are must-haves for maintaining nail health and achieving long-lasting color. These OPI essentials help prep, protect, and support professional-quality manicure results at home.

Q: Can I use any LED or UV lamp with OPI products?

While some third-party lamps may work, OPI recommends using the OPI Star Light Gel Lamp for optimal results. It cures OPI GelColor and OPI GELevate layers in 30 seconds when the correct timing is followed to prevent under-curing or wrinkling.
