Final answer:
Wavy nail ridges, often the result of uneven growth due to injury, are known as nail pitting. Nail pitting can occur when the nail matrix is damaged or interrupted. It can be a sign of underlying health conditions or trauma.
Step-by-step explanation:
Wavy nail ridges, often the result of uneven growth due to injury, are known as nail pitting. Nail pitting can occur when the nail matrix, the area where the nail is formed, is damaged or interrupted. This can happen due to trauma, such as hitting the nail against a hard surface, or as a result of underlying health conditions like psoriasis or eczema.
The uneven growth of the nail matrix can lead to the formation of ridges and indentations on the nail surface, giving it a wavy appearance. Nail pitting is usually harmless, but in some cases, it can be a sign of an underlying health issue. If you notice persistent or worsening nail ridges, it's best to consult a healthcare professional for a proper diagnosis and appropriate treatment.
