The Best Shampoo You Can Buy for Oily Hair Is Just $2

Clarifying formulas are the powerhouse cleansers of shampoos, delivering the most purification and easily removing oil and dirt. This super lightweight Suave formula is the GH Beauty Lab go-to for deeply cleaning strands in all our hair swatch studies! Plus, you truly cannot beat the price, making this Lab favorite pick our best overall and our best value choice.

GH Product Analyst Grace Wu uses this shampoo once a week: "The first time I used this shampoo, I was blown away by how squeaky clean my terribly oily hair could feel," she says. "My hair doesn't get as oily as it usually does for a few days after using it." Many reviewers are unhappy with the smaller sized bottle even though it remains the same price as the previous larger bottle.

Oily strands and parched ends are a tough combo — but luckily are no match for this multi-tasking L'Oréal shampoo. A blend of three types of refined clay help reduce oil at the roots, while keeping the rest of your hair nourished and healthy at a bargain price. "This is an incredible shampoo," says one reviewer. "Cleans my scalp and leaves my hair really soft." However, some reviewers disagree, finding their hair and scalp to still be oily after use.

Rosemary and mint clean the hair with a refreshing scent. Aveda's purifying shampoo is also a winner of our GH Sustainable Packaging Awards. Its bottle is made of 100% recycled plastic and has no secondary packaging. GH experts like that you can recycle the press-caps; the design also dispenses the perfect amount of product to avoid waste. "My hair gets oily the next day after washing," a reviewer writes. "With this shampoo, I can push my hair washing to every three days." Some reviewers note that they would prefer a pump for the bottle.

If you have oily hair and an oily scalp, this detoxifying shampoo is a great choice. It deeply cleanses hair and can extend the amount of time between washes. One of our GH staffers uses it once a week: "It has been a game changer for me, and allows me to go four days between washes (where I used to have to go every two days)." Note that this is on the pricier side.

Harklinikken's stabilizing shampoo is a favorite of celebrity hairstylist Ashleigh Marie. She likes that it's "very clarifying but doesn’t overdry the hair and helps to stabilize the scalp microbiome." The brand claims this pricey hair wash is formulated to reduce excess sebum while also promoting conditions for hair growth.

For a gentle yet effective clarifying shampoo, turn to this Olaplex formula. Marie likes this one for its deep cleanse. "It removes buildup and minerals on the scalp and hair but also isn’t super stripping," she shares. Our former Beauty Assistant has also used this shampoo and noticed a significant improvement in hair shine even after just one use, though it's pricey.

Great if you have oily hair and a dry, itchy scalp, this Head & Shoulders shampoo tackles both issues. Formulated with the flake-fighting active ingredient zinc pyrithione, there’s a reason the brand has become the most trusted pick for combatting dandruff. "I no longer have an itchy scalp and my hair isn’t oily," shares one Amazon user. Some reviewers didn't find the formula to be as effective for them, though, as they still experienced some oiliness after use.

With nutrient-rich electrolytes and super nourishing (but weightless) coconut water, this lightweight shampoo will quench dry ends without weighing down hair. In addition to loving the scent, one reviewer shares that "it doesn't leave residue and makes my hair feel so fresh and soft compared to other shampoos." However, this hydrating shampoo may not be as effective for those with extra oily hair.

A salon splurge that’s worth it, Kérastase’s shampoo (and complementary conditioner) were stars in GH Beauty Lab testing for plumping strands but feeling featherlight. They won for leaving hair feeling clean after rinsing and also earned top points for weightlessness in Lab evaluations. "It left my hair full of body and was nice and thick without weighting my hair down," a tester raves. "All day it had that just-washed look." However, this pricey shampoo features a screw-on lid design that was very polarizing to testers.

Rahua's top-rated organic shampoo uses natural lemongrass and green tea to remove excess oil and balance the scalp, while helping to enhance body and volume. Plus, the soothing lavender scent makes washing your hair a spa-like experience. "It tends to get oily fast and my hair is very flat," a reviewer says. "This natural shampoo cleans well and gives a squeaky clean feeling without drying my hair out." However, note that this pricey pick doesn't lather as much as other shampoos.

This Bumble and Bumble weekly intensive deep cleanser is known to remove every last drop of oil, product buildup, dirt and pollutants from your hair and scalp. This Sephora best-seller is great for fine or thick hair, but you may want to skip if you color to prevent fading. "This product is great for breaking down product buildup from styling your hair," a reviewer shares. "I used to use this a lot before I colored my hair, but stopped ever since because it’s not color safe."

Unlike traditional shampoos, this uber cool formula from Carol's Daughter starts as a water and transforms into a foam once you massage it into hair and scalp. It gives hair a deep clean, thanks to the magnet-like power of micellar water to draw out impurities, while also detangling and hydrating hair.

Plus, it has a targeted applicator, allowing you to focus the product on your roots. "The nozzle on the shampoo bottle lets me get the product directly on my scalp, creates a nice lather and leaves my hair clean and smelling great," says one reviewer. Some reviewers find that the product leaves their hair feeling very dry, though.

This certified organic formula from Avalon Organics gently cleans hair, while removing excess oil and product buildup. A powerful blend of lemon essential oil, quinoa protein, aloe and vitamin E help smooth and seal hair's cuticle, making strands smooth and shiny. Plus, it has a soft and subtly sweet citrus fragrance. "The scent is light and pleasant, not overpowering and does not linger," says one reviewer. Take note, this shampoo may not lather as much as others.
