Weak nails

Frequently asked questions

Strengthening weak nails

Nails that split, break or become ridged often reflect a fragility of the keratin that makes them up. External factors (household products, nail polish removers) and internal ones (diet, deficiencies) come into play. Beyond everyday protective habits, certain micronutrients play a role in nail strength. Food supplements provide nutritional support from within.

Among the valued actives, zinc contributes to the maintenance of normal nails, as does biotin, which contributes to the maintenance of normal hair and nails. These micronutrients accompany the structure of the nail over time.

For a visible result, allow at least three months of a course, the time for a new nail to grow, combined with protective habits: gloves for housework, moisturising the cuticles and a diet rich in protein. Consistency makes the difference.
