What Causes Oily Hair
Oily hair happens when the scalp produces excess sebum, the natural oil that protects skin and hair. Genetics, hormones, and overwashing can increase oil production. According to the American Academy of Dermatology, washing too often can signal the scalp to make more oil.
How to Choose Shampoo for Oil Hair
Look for lightweight, clarifying shampoos with ingredients like salicylic acid, tea tree oil, or charcoal. These help remove buildup without stripping the scalp completely. Avoid heavy silicones and moisturizing formulas designed for dry hair, as they can weigh hair down and add grease.
How Often to Wash and Best Practices
Most people with oily hair benefit from washing every other day or daily with a gentle formula. Focus shampoo on the scalp and let the suds rinse through the ends. Use lukewarm water, avoid hot showers, and rinse thoroughly to prevent residue that can make oil worse.
