Nails

The nails act as a protective barrier for the fingers, shielding them from impacts, cuts, and other traumas that could cause damage. Taking care of one's nails strengthens this natural protection and contributes to the overall health of the hands, preventing infections and maintaining good hygiene.

Brittle nails: how to strengthen them?

Brittle nails (onychorrhexis) is a common nail disorder, affecting up to 20% of the population. They are more prevalent in women and individuals over the age of 50. Whether it's an internal condition or external environmental factors, anything from a thyroid disorder to the natural ageing of the nail, or even overexposure to detergents, can make nails either soft and brittle (high humidity) or dry and brittle (low humidity). While nothing can be done about age-related nail changes, it is possible to reduce the risk of cracking and fragility of nails linked to other causes. Here are some measures to take in order to protect your nails so they remain strong.
