The nails must be regularly treated to preserve them and argan oil is also used for this! The benefits of argan oil are beneficial for the health and beauty of the nails. Nails are made up of keratin. The unsaturated fatty acids and vitamins E of argan oil provide hydration and stimulate the creation and regeneration of keratin in the nails. To restore brittle nails, mix pure argan oil with a few drops of lemon juice. Soak your nails for 10 minutes. If you have damaged nails, this treatment should be performed every 2 days. For regular maintenance, it should be done once a week.
