What does excessive scalp oiliness indicate about the sebaceous glands?

Excessive scalp oiliness is a clear indication of overactivity in the sebaceous glands. These glands produce sebum, which is a natural oil that helps to moisturize and protect the skin and hair. When the sebaceous glands are overactive, they produce more sebum than necessary, leading to an oily scalp. This condition can create a variety of issues, such as greasy hair and potential scalp problems like dandruff or seborrheic dermatitis. Therefore, recognizing that overactivity in the sebaceous glands is the root cause of excessive oiliness is crucial for understanding how to manage scalp health effectively.
