What Nail Strengtheners Do
Nail strengtheners are base coats or treatments designed to reduce peeling, splitting, and breakage. They typically contain proteins, keratin, calcium, or hardening polymers that form a protective layer or reinforce the nail plate. Many formulas also include moisturizers to prevent brittleness.
Top Ingredients to Look For
Effective strengtheners often list keratin, hydrolyzed wheat protein, or silk amino acids for flexibility. Calcium and formaldehyde derivatives add hardness, while vitamin E and jojoba oil help maintain moisture. Avoid products with high concentrations of harsh solvents if you have sensitive nails.
How to Choose the Right Product
Consider your nail type: flexible nails benefit from protein-rich formulas, while very hard nails may need a gentler, moisturizing option. Check for non-toxic certifications and avoid strong irritants. For more guidance on ingredient safety, see the American Academy of Dermatology at nail care tips. Apply as directed, usually as a base coat, and reapply every few days for consistent results.
