Strengthening Base & Top Coat. How it works:
- Sally Hansen Double Duty Base & Topcoat is an all-in-one moisturising base coat & protective shiny top coat.
- As a base coat: containing moisturising & nourishing pro-vitamin B5, smoothes the nail surface & helps grip nail colour for longer wear.
- As a top coat: protects manicures with nylon, a patented nail hardener. Nails are shielded with a hard, shiny, chip-resistant finish.
