Even if your fingernails are thick, you need to protect them, so that they will not become damaged by their impact with the strings. Thin nails, on the other hand, will need additional support and strengthening in order to produce a good tone. You need to discover the best method for you. Some guitarists apply a base coat of clear nail lacquer. After it is dry, they apply one of more thin coats of cellulose glue evenly over their surface, building up the nails in layers until they reach the desired thickness.
Other players like to provide added strength by applying the glue together with one or more layers of thin tissue, ‘Micropore’ adhesive tape or teased out cotton wool. Generally speaking, glue alone is usually adequate. Often these strengthening techniques cause your nails to dry out. To prevent this from occurring, remove the protective layers each day. You may find that it peels off easily, but most likely, you will need to use a nail polish remover to which you need to add a slight amount of oil.
There are many everyday objects which might prove hazardous to your nails. Soon, you will develop a keen awareness of the risks inherent in handling them, learning to avoid actions which might tear or otherwise harm your nails. Some of these objects that you need to be keenly aware of include handles, switches and clock winders. Also, keep in mind that most detergents and soaps will dry your nails, causing problems. Rubber gloves can also cause trouble, not allowing your skin and fingernails to ‘breathe.’ Carry an emery board with you at all times so that you can provide first aid for your nails when you encounter any of these common hazards. An emery board can prevent small cracks from becoming bigger. Large cracks, tears, or flaking, however, may require careful repairs with glue, even requiring you to use paper to make the needed repairs.
