Oily

Testing notes: “This shampoo has probably one of the best textures on this list. It’s a gel that foams into a really nice lather and washes out easily for smooth, grease-free strands. I noticed that my scalp was less flaky and oily post-wash and I’d definitely recommend it for anyone looking to combat oily roots and an unbalanced scalp,” says Glamour’s Kilkeary.

Best for Fine Hair: Nécessaire Rosemary Shampoo

• Pros: Smells great; lightweight formula; lathers nicely
• Cons: Pricey

This luxurious rosemary shampoo might be a little pricey, but Glamour’s Kilkeary says it’s well worth it if you have fine, oily strands. Kerry E. Yates, a trichologist and founder of Colour Collective, agrees. “It has antimicrobial properties that can decrease inflammation and help increase blood circulation,” she says. This can help thicken your hair over time and make your hair look fuller and more voluminous (sans the grease). It also has ceramides that nourish and hydrate the scalp’s skin barrier.

Testing notes: “My hair gets pretty oily if I skip a wash day, so I simply can’t go without a clarifying shampoo. This super-nourishing shampoo (which smells amazing, by the way) helps absorb grease and promotes growth in sparse areas, and I’ve noticed such a difference in my hair since I first started using it. The hair at my root is much thicker and stronger, and I don’t find that my strands get as greasy as quickly. My hair feels and looks fresh and has much more body and volume,”Glamour’s Kilkeary says.

Best for Dry Ends: Kérastase Bain Divalent Balancing Shampoo

• Pros: Keeps hair shiny but not greasy; helps with itch
• Cons: Expensive

Have greasy roots but dry ends? Bradley Leake, a professional hairstylist based in Los Angeles, suggests this balancing shampoo, which he describes as “an ultralight formula that balances scalp oiliness.” It contains amino acids to reduce excess oil and odors, while vitamin B₆ helps gently nourish lengths. Leake also notes that it’s a great volumizing shampoo for flat hair, which is yet another reason he loves using it with clients.

Testing notes: “My hair tends to get shiny after a day, but I’ve noticed that after using this Kerastase shampoo, my strands stay shine-free for up to three days. Just keep in mind that it doesn’t lather at all, so I would recommend double- (or triple-) washing with another shampoo. I have coarse, long hair so I do end up using a lot of product, which adds up, but I can honestly say that this is the only hair product that’s actually helped my greasy strands,” says Glamour senior commerce editor Jenifer Calle.
