Sick of having greasy hair? Snagging the best shampoo for oily hair is a great place to start. Board-certified dermatologist Dr. Marisa Garshick explains the importance of prioritizing the right shampoos: ones formulated with clarifying ingredients specifically formulated for washing away dirts and oils. She also emphasizes the importance of ingredients like salicylic acid, which can help curb oil production before it starts. “It's important to wash your hair and scalp regularly to prevent buildup of excess oil,” says Dr. Garshick. “That said, it's also important to avoid over-drying the scalp and avoid using too many products that can strip the scalp of its natural oils.” We asked experts to recommend the best shampoos for oily hair, with options pulled from the drugstore to DTCs and everything in-between. Best Shampoo for Oily Hair Overall: Olaplex No. 4C Bond Maintenance Deep Clean Clarifying Shampoo Save to wishlist Save to wishlist Olaplex No. 4C Bond Maintenance Deep Clean Clarifying Shampoo $34 Nordstrom Pros & Cons AccordionItemContainerButton LargeChevron Pros Sulfate and paraben-free Lightweight Cons Some ingredients can be stripping Key ingredients Cocamidopropyl betaine, bis-aminopropyl diglycol dimaleate Price per ounce $3.50 Clarifying shampoos are a generally great choice for those with oily hair because they contain surfactants, which remove excess buildup and oil. Dr. Garshick explains that “the surfactants used in clarifying shampoos tend to offer a deeper cleanse than regular shampoos, making them especially good for those with oily scalps.” Cocamidopropyl betaine is the main surfactant in this formula, but it’s also mixed with the brand’s proprietary ingredient bis-aminopropyl diglycol dimaleate. (This is what Olaplex is referring to when they hype-up their bond-repairing abilities, since it’s been found to repair breakage without weighing the hair down.) In general, this is a great formula that makes your hair feel stronger and more manageable, and it gets bonus points for working into a rich lather.
