Why Greasy Hair and Dandruff Often Occur Together
Greasy hair happens when the scalp produces excess sebum. This oil can mix with dead skin cells, leading to visible flakes and irritation. According to the American Academy of Dermatology, frequent washing with the wrong products can worsen both oiliness and flaking.
Key Ingredients to Look For
Effective shampoos often include zinc pyrithione, selenium sulfide, or ketoconazole to control fungus and flakes. Salicylic acid or coal tar can help remove excess oil and buildup. For sensitive scalps, formulas with tea tree oil or gentle surfactants may reduce irritation without stripping natural moisture.
How to Use Shampoo for Best Results
Focus the product on the scalp, massaging gently with fingertips for one to two minutes before rinsing. Avoid very hot water, which can increase oil production. If flakes persist or the scalp is red, consult a board-certified dermatologist for a personalized treatment plan.
