Why Oily Hair Gets Dandruff
Oily hair occurs when the scalp produces excess sebum. This environment can encourage the yeast Malassezia, which triggers flaking and irritation. A shampoo that removes oil while treating the root cause helps reduce both greasiness and flakes.
Key Ingredients to Look For
Effective formulas often include zinc pyrithione, which fights fungus and bacteria; salicylic acid, which helps dissolve oil and flakes; and ketoconazole, an antifungal agent. These ingredients target the causes of dandruff while helping to regulate sebum production.
How to Choose and Use the Right Shampoo
Select a gentle, sulfate-balanced shampoo that controls oil without stripping the scalp. Apply to wet hair, massage the scalp for 30 to 60 seconds, then rinse thoroughly. For persistent dandruff, use the product consistently and follow with a lightweight conditioner on the ends only.
