Tried this on the recommendation of a beauty guru. I know how to properly do my nails. Cuticle oil, buffing, filing, cuticle oil, push cuticles back, wash, base coat (which always works well with other polished), 2-3 thin coats, top coat. There was literally no reason for this product to perform as poorly as it did. Takes FOREVER to finally cure between coats. The slightest test of tackiness leaves smudges, bare spots. For being marketed as “hard as nails” this product NEVER actually hardened. It stayed soft as can be. I let coats dry 5-10 minutes and even after top coat and another 30-40 minutes the polish was soft and scraped away at the slightest bump or scrape against another nail. Thank goodness it was cheap but I will never buy another Sally Hansen polish. A huge waste of time. In the garbage it goes.
