Excessive oil on the scalp typically indicates that the sebaceous glands, which are responsible for producing sebum (the natural oil of the skin and hair), are overactive. This overactivity can be influenced by various factors such as hormonal changes, diet, or genetic predisposition. When these glands produce too much sebum, it can lead to a greasy appearance, potential buildup on the scalp, and may also contribute to issues like dandruff or scalp acne.

In contrast, unhealthy hair growth is not directly linked to the amount of oil produced; rather, it pertains to the overall health of the hair and scalp, which may be affected by a variety of nutritional and health factors. A balanced diet would generally promote healthy hair and scalp conditions, rather than being associated with excessive oil production. While more frequent washing might help manage the appearance of oiliness, it does not directly address the root cause, which is the activity level of the sebaceous glands. Therefore, recognizing overactive sebaceous glands as the correct answer provides insight into the biological processes affecting the scalp's oil levels.
