Kim Coleman, age 15, of Tulsa, Okla., for her question:

HOW DO HANGNAILS OCCUR?

Each of your fingernails has an opaque fold of skin at its base that is called the cuticle. A hangnail, which is a common problem for many people, occurs when the cuticle becomes dry and is torn. A ragged and often triangular flap of skin appears, and it can act as a lever to tear into the deeper living layers of skin if allowed to remain.

Hangnails can be removed at the base, using a clean pair of sharp scissors. Care must be taken so that the area doesn't become inflamed.

Fingernails should receive special care. Soak the nails to soften the cuticle, and then press it back gently with the fingertip of the opposite hand. Lubricating cream can also be used to keep the cuticle soft.
