👉 Trachynema is a condition characterized by hair growth on the skin, often caused by an autoimmune disorder in which the body produces too much thyroid hormone. It can affect both children and adults, affecting the appearance of the scalp, eyebrows, eyelashes, and other areas of the face. Trachynema is usually mild and self-limited, but severe cases may require medical intervention to prevent further hair loss or to manage symptoms.
