The scalp is the skin that covers the top of the head and is the site where hair grows. The scalp is made up of several layers of skin, including the epidermis, dermis, and subcutaneous tissue. The scalp also contains blood vessels, nerves, and hair follicles.

The scalp is susceptible to a variety of conditions such as dandruff, scalp psoriasis, seborrheic dermatitis, and scalp acne. These conditions can cause symptoms such as itching, flaking, redness, and inflammation.
