What Causes Hair to Become Greasy?

The main causes of hair becoming greasy include overactive oil glands, hair texture, environmental factors, and hair care habits.

1. Overactive oil glands
2. Hair texture
3. Environmental factors
4. Hair care habits

The interplay among these factors reveals the complexity behind greasy hair.

1. Overactive Oil Glands: Overactive oil glands in the scalp cause excessive oil production. The sebaceous glands secrete sebum, a natural oil meant to protect hair and skin. However, some individuals have glands that produce more oil than necessary, resulting in greasy hair. According to a study by J. Dawber and R. D. A. M., published in the Journal of Dermatology in 2015, hormonal changes such as puberty or menstruation can trigger increased oil production. These hormones stimulate the sebaceous glands, which may contribute to greasy hair.
