Which type of nail enhancement is known for its flexibility?

The type of nail enhancement that is known for its flexibility is gel. Gel nails are created using a gel product that is cured under a UV or LED light, which not only hardens the product but also allows it to retain some flexibility. This flexibility makes gel nails less prone to chipping and breaking compared to other types of enhancements, particularly in certain situations like impact or pressure.

Gel nails provide a more natural appearance and can be easier on the natural nail, as the flexibility helps reduce stress on the nail bed. This quality also allows them to move more naturally with the natural nail growth, offering a comfortable wear experience.

In contrast, acrylic nails are known for their rigidity and durability but can be more prone to cracking under stress due to their firmer nature. Hard gel, while it does provide some level of flexibility, still does not match the overall pliability of regular gel enhancements.
