Buying advice

When selecting a nail strengthener, consider your nail type: if nails are peeling, look for protein-rich formulas; if dry, choose moisturizing oils. Check ingredients like keratin, biotin, or calcium. Apply consistently, usually as a base coat or alone, and avoid overuse as it can cause brittleness. Price and brand reputation are also factors.
