Which product can help hydrate brittle nails?

Cuticle oil or nail strengthening treatments are specifically designed to provide hydration and nourishment to brittle nails. These products typically contain a mixture of oils and vitamins that help to moisturize and enhance the overall health of both the nails and the surrounding cuticle area. Hydration is key in preventing brittleness, as it helps maintain the flexibility and strength of the nails.

Nail polish remover and acetone are solvents that can actually dry out the nails, leading to increased brittleness and damage. A base coat, while useful for protecting nails from staining and enhancing the longevity of nail polish, does not offer hydration or strengthening properties to combat brittleness. Therefore, using cuticle oil or nail strengthening treatments is the best choice when looking to improve the condition of brittle nails.
