When a nail is injured, it can assume a number of different appearances. The most common, of course, would be a discoloration of the nail plate due to bleeding under or around the nail. This condition is referred to as a subungual hematoma, or hemorrhage in the nail plate (similar to a bruise on the skin). When this occurs, the blood accumulates under the nail and it usually causes the nail plate to separate from the nail bed. In addition, the accumulation of blood underneath the nail plate can create pressure and pain. To relieve the pressure, a doctor will cut back the nail plate with a nail nipper to release the accumulated blood. This now leaves the nail bed exposed, and the client will have to wear a bandage for a few days. The new nail will grow rapidly when the separated nail plate is cut away. Once the discolored, bruised, or infected nail has been properly diagnosed by a doctor and treated, it is then safe to work on that client, provided there is no sign of infection, bleeding, pain, or allergy to acrylic. A tip may be applied to the remaining nail plate if the client has no sensitivities to the products (not recommended for clients with chronic lifting). There is no harm in applying nail polish. Clients may actually appreciate the camouflage.
