The scalp is the skin covering the top of the head, which is rich in hair follicles. It plays a crucial role in protecting the skull and supporting hair growth. The scalp consists of several layers, including skin, connective tissue, and muscle, and is highly vascularized, meaning it has a good blood supply. The health of the scalp is important for overall hair health. Conditions such as dandruff, psoriasis, and seborrheic dermatitis can affect the scalp, leading to discomfort and hair loss. Regular cleansing and moisturizing can help maintain a healthy scalp environment, promoting better hair growth and overall scalp health.
