These are specially formulated products that should be massaged into the nails and cuticles, ideally at the end of each day. They contain a wide variety of ingredients that are designed to nourish the nails and encourage healthy new growth. They are good for restoring the appearance of dry, brittle and splitting nails. Many contain natural ingredients such as vitamin E, calcium pantothenate (vitamin B5) and the comfrey. The herb comfrey is well known for its ability to speed the healing process by accelerating cell division. Some people also find that massaging the nails regularly with jojoba or almond oil is very effective and can help speed up the growth of nail tissue. Olive oil is a cheap altenative.
