A simple soak in castor oil can strengthen fingernails and help heal dry and cracked cuticles. Castor oil will soften the cuticles and form a protective layer over the nail. To create the nail treatment, add the castor oil to a small bowl and warm in a hot water bath. Soak your fingertips in the warm oil for 5 to 10 minutes. When the cuticles are soft, you can push them back with a clean soft cloth and buff if necessary.
If you would like to add some essential oils, lavender, geranium, and carrot seed are good ones to start out with.
