Best known for its ability to improve the skin and hair, argan oil also provides benefits for the fingernails. Every day, your fingernails are subjected to a great deal of abuse. Think about how many times you wash your hands during the day or perform household tasks such as washing the dishes. These activities can really take a toll on your nails, leaving them broken and battered. Using argan oil is a great way to bring them back to a healthy state again. Over time, manicures and pedicures can leave your cuticles dry and hard. This is another area where argan oil can help. Its deep moisturizing properties can give new life to your cuticles, helping to make them healthy and attractive.
