Why does hair get greasy looking?

Hair can get greasy over time either because of oils secreted from the scalp or because of oily hair care products. Some people produce more oils than others. The excess oil may be due to hormone surges triggered by puberty, stress, pregnancy, menstruation, or hormonal medications. Many hair care products contain oil and can make your hair look and feel greasy. These products may also clog the pores in your scalp and cause skin problems.

There are a few things you can do to prevent or address greasy hair. Make sure you shower and shampoo daily. It's okay to brush your hair, but avoid brushing too hard or too frequently. The oils from your scalp will spread throughout your hair, causing it to look greasy. Also, avoid using products designed for oily hair.
