Oily scalp
An oily scalp, also known as seborrhea or seborrheic dermatitis, occurs when the sebaceous glands produce an excessive amount of sebum, the natural oil that lubricates the scalp and hair. Several factors can contribute to an oily scalp, and treatment recommendations from a dermatologist may include:
Causes of Oily Scalp:
- Hormonal Imbalance: Fluctuations in hormone levels, such as during puberty or menstruation, can lead to increased sebum production.
- Genetics: Some people have a genetic predisposition to overactive sebaceous glands, leading to oily scalp and hair.
- Stress: Emotional and physical stress can affect hormone levels, potentially triggering an oily scalp.
- Seasonal Changes: Humid and hot weather can stimulate sebum production.
- Hair Care Products: Using heavy or oil-based hair products can exacerbate oiliness.
- Overwashing: Paradoxically, washing the hair too frequently can stimulate more sebum production as the scalp tries to compensate for the lost oils.
