Oily hair is caused by an overproduction of sebum from sebaceous glands, often driven by genetics, hormonal changes, stress, or improper hair care routines. It can be treated by using clarifying shampoos, washing with lukewarm water, avoiding over-brushing, using lightweight conditioners, and cleaning hair tools regularly.
Common Causes of Oily Hair
- Hormonal Changes: Puberty, pregnancy, or menstrual cycles can trigger increased sebum production.
- Genetics: Some individuals are genetically predisposed to having larger or more active oil glands.
- Incorrect Hair Care Routine: Over-washing can strip the scalp, causing it to produce more oil to compensate, while under-washing allows buildup, say Mediceuticals and Healthline.
- Product Buildup: Using heavy conditioners or styling products containing silicones can make hair appear greasy, note Medical News Today and Healthline.
- Environmental Factors: Hot weather or high humidity can increase sweat and oil, according to mediceuticalsusa.com and naturabrasil.fr.
- Touching Hair Often: Frequently touching your hair transfers oil from your hands to your hair.
