Buying advice

When choosing a nail thickening solution consider the severity of your nail issues, budget, and how often you can reapply. Budget-friendly options like Sally Hansen work for mild softness, while protein-rich formulas such as Nailtiques are better for heavily damaged nails. For daily wearers, a product that doubles as a polish (e.g., Orly Nail Defense) offers protection without extra steps.
