What condition involves the overgrowth of skin cells and can affect nails?

Psoriasis is a chronic autoimmune condition that leads to the rapid overproduction of skin cells. This overgrowth creates thick, silvery scales and dry, red patches that can sometimes appear on the nails as well. When psoriasis affects the nails, it can lead to a variety of changes, including pitting, discoloration, and even separation of the nail from the nail bed. This condition can significantly impact both the appearance and health of the nails, making it a relevant concern for manicurists and those in the beauty profession.

In contrast, dermatitis and eczema are primarily inflammatory skin conditions that can cause redness, itching, and irritation but do not necessarily involve the same level of skin cell overproduction seen in psoriasis. Allergic reactions usually manifest as hives or redness and swelling, but they do not lead to the chronic changes associated with nail involvement that psoriasis does. Understanding the specific characteristics of psoriasis helps in recognizing its implications in both skin and nail care.
