Get Rid of Greasy Hair With These 28 Expert-Backed Tips

Wash Your Hair With a Sulfate-Free Shampoo

Most shampoos contain sudsy detergents called sulfates that can over-cleanse and dry out your scalp. For the first few uses of a sulfate shampoo, your hair might feel squeaky clean, but over time, your scalp may start to overproduce oil to make up for the dryness. So to keep the greasiness at a minimum, opt for gentle, sulfate-free shampoo formulas that will cleanse your strands without stripping your scalp or hair of the oils it needs to stay strong and healthy.

Use Dry Shampoo Between Washes

If you're someone who can't fathom going a single day without washing your hair because your strands accumulate way too much oil– you're not going to like this, but– fight the urge and skip your daily hair wash. It might sound counterintuitive, but the less you wash your hair, the better off it'll be. If you need to stretch your wash, spritz some of Dove's Volume & Fullness Dry Shampoo onto your roots to keep hair looking clean (even if it isn't). If your usual technique involves an aimless spray of dry shampoo, try this technique instead: Part your hair in small sections from ear to ear, and spray the product at the roots to ensure your entire head is covered.

Try a Texture Spray

As awesome as dry shampoo may be, it can do more harm than good for certain hair types. "If your hair is constantly oily, steer clear of over dry-shampooing," says Laura Polko, a Los Angeles-based celebrity hairstylist whose clients include Gigi Hadid, Chrissy Teigen, and Candice Swanepoel. Instead, she recommends applying a texture mist like Bumble & bumble's Thickening Dryspun Texture Spray. "It's great at reviving day two or three hair," says Polko.

Wear Your Hair Up

Depending on your hair type, your roots might start looking a bit dirty around day three, but that's OK. The beauty is that you can capitalize on the grease for don't-care 'dos. These styles are chic but purposefully messy, meaning a little grease and grit from the dry shampoo or texture spray will only make them better. We love a low, loose chignon that you can either tie up with a hair tie or clip in place with a claw clip.

Rinse Hair With Apple Cider Vinegar

On day four or so, we'll let you cheat a bit and do an apple cider vinegar rinse in warm (not hot) water—hot water may be too drying. Many people believe that raw, organic apple cider vinegar, like Fekkai's Apple Cider Detox Rinse, is acidic enough to restore the pH balance of your hair and rid the scalp of buildup, yet mild enough that it doesn't strip your strands of essential nutrients. And, according to Lauren Thompson, a stylist at Nunzio Saviano Salon in New York City, it's also gentle enough to use on color-treated hair.

If you use pure apple cider vinegar, the best way to apply it is to pour a mixture of it into your hair while in the shower, work it through your roots, and rinse it out. Not only will it remove the oily buildup, but it will also leave your hair unbelievably soft and shiny. Win-win. For the ACV mixture, you'll want to mix about two to three tablespoons of pure apple cider vinegar into a bottle of water to help balance the acidity.

Limit the Use of Styling Products

Loads of hairspray and creams may cause buildup on the scalp, which then leads to excess grease, so it's best to skip them if you can.

Allison Friedman, a senior stylist at the Warren-Tricomi Salon in New Jersey suggests applying just one styling product to the scalp and only if you have flat hair that needs a boost of volume. "The only product you ever want to put on your roots when your hair is damp is a mousse or a root lifter before blow-drying." We like the Living Proof Full Thickening Mousse because it gives the hair great hold without coating the strands with a sticky residue or weighing them down over time.

Alternate Between Shampoo Formulas

Though it's best to limit your product use when "training" your hair to produce less oil, if you feel like you're experiencing buildup over time, use a clarifying shampoo every so often to reset your scalp when necessary. Gentle shampoos are better for regular use, but a clarifying shampoo works to deep clean your scalp, roots, and strands when your hair starts feeling heavy or bogged down. It's smart to alternate the formulas you're using in general anyway– even if it's not to use a clarifying shampoo– because if you stick to one for too long, you may notice that your hair isn't getting as clean as it once was.

Exfoliate Your Scalp

Scrubs not only feel amazing on a greasy, irritated scalp, but they're also great for keeping the hair and skin on your head looking healthy and clean. Polko likes using scalp scrubs to remove any excess product buildup and oil, such as Ceremonia's Papaya Scalp Scrub. The lathering formula uses pink salt and papaya enzymes to exfoliate and balance the scalp's natural oils while guava leaf and prickly pear cactus moisturize it.

Let Your Hair Air-Dry

Believe it or not, "blow-drying too much can also cause your hair to produce excess grease, so try letting your hair air-dry instead," says Polko. Sure, air-drying can be time-consuming, but there are ways to speed up the process. "After washing, I recommend using a leave-in-conditioner on your ends rather than an oil because it keeps your hair looking fresh while reducing your dry time." Touching your hair too much before it's dry may create frizz, especially on wavy or curly textures, so try applying your products and letting your hair sit until it's dry. We love JVN's Complete Hydrating Air Dry Hair Styling Cream as it boosts shine while eliminating frizz.

Take a Supplement

"Your hair, skin, and nails are a direct reflection of what you put into your body. Supplements are a great way to achieve shinier, healthier hair," says Polko. We should add that hair supplements are not regulated by the FDA, which means you should take their claims with a grain of salt. Still, some people experience good results from taking hair supplements, so if you're interested in giving them a go, try one designed to manage a greasy scalp. Polko is a fan of Nutrafol, which is "rich in omega-3s and B vitamins" and can help to encourage healthy hair growth. Always consult your doctor before adding any supplement to your diet.

Pay Attention to Your pH

It is important to note that if you are trying to prevent stripping your hair while using shampoo (with or without sulfates), you should pay attention to the product's pH. "Make sure the shampoo has a pH of 5.5 or less," says Sophia Emmanuel, an IAT-certified trichologist and licensed cosmetologist based in New York. "This way, the hair is not as dry once the shampoo is rinsed out and the scalp will not overproduce oil to make up for what was lost. "

Look for the Word, 'Clarifying'

"Anything clarifying will help control oil and extend your wash," says Polko. This MoroccanOil Clarifying Shampoo nourishes and restores the hair with ingredients like Argan and avocado oils and keratin while it removes buildup on the hair strands without the use of sulfates.

Double-Up On Shampoo

If your roots get extra greasy, however, Friedman says the trick is to apply dry shampoo immediately after you've washed your hair. "I apply some dry shampoo directly to my roots so that as the hours go on and your scalp starts to produce oil, the dry shampoo will start working immediately to combat that oil. And you can reapply as much as needed throughout the next days to keep the oil at bay and your blowout as fresh as possible."

Change Your Linens

Consider how much time you spend resting your head on your pillow and now think how often you change your pillowcase. Every night, it absorbs the oil and grime from the day before, and if you're not frequently washing your linens, all of that ends up rubbing on your scalp. So, you could be doing everything else right in your hair care routine, but if your pillowcase is dirty, all those efforts could be in vein.

Use a Sweatband

What if you work out? Of course, having a sweat sesh at the gym means your hair will get oily faster (and will need some freshening up). In this instance, Thompson suggests using a sweatband to absorb sweat and oil at the hairline to prevent it from reaching your hair.

Take Steps to Extend a Blowout

At night, spray hair with dry shampoo to help absorb any oil throughout the night, and clip your hair up in a bun on the top of your head, says Thompson. "I just recently started doing this and it helps extend the life of a blowout." If your hair is in desperate need of a rinse, soak it in the shower with just water, and use dry shampoo once dry.

Experiment With a Wet Look

Rather than pulling your hair up, try working with the grease instead of against it. Try a slicked-back wet look on the last day before a wash. To do so, combine equal parts gel and cream to create a styling balm that allows for soft, touchable hold, and use your fingers to rake the product through the length of your hair. No one will know it wasn't clean, to begin with.

Prolong the Time Between Washes...

How long you can go between washes depends on your hair type and texture, but try to prolong the time between washes as long as you can (anywhere from every other day to once a week). And remember two key things afterward: Touch it as sparingly as possible, and don't overuse styling products or dry shampoo. "By doing so, you overwork your scalp, increasing oil production," says Polko.

...Or Wash More Frequently

On the flip side, maybe your hair does need to be washed every day. People with very oily skin and/or very active lifestyles may benefit more from a daily wash routine rather than stretching out the time in between washes.

Improve Your Washing Technique

Using the right technique is critical to diminishing the appearance of greasy roots. Since oil starts at the scalp, you want to make sure you're working your shampoo and scrubs into the roots and taking time to massage them in. This will break up any buildup and help to clear clogged hair follicles. Furthermore, make sure you're paying attention to your whole head versus just the hairline—even the back of your head needs TLC.

Apply Conditioner Sparingly

As with many styling products, conditioners can weigh down the hair. To keep your roots voluminous, concentrate conditioner only on the ends of the hair, staying away from the roots (which tend to absorb the most oil).

Clean Your Hair Tools

A dirty hairbrush, comb, or hot tools (straightener, curling iron, etc.) can distribute oil and grime throughout the hair. To ensure that you cut through oily residue and buildup and aren't depositing it back onto your clean hair, wash your brush and comb at least once per month.

Try a Scalp Mask

Try a product formulated specifically for oily hair, like Briogeo's Scalp Revival Charcoal + Tea Tree Cooling Hydration Mask which uses balancing and hydrating ingredients such as aloe, hyaluronic acid, and charcoal to reset the scalp.

Turn to Tea Tree Oil

Tea tree oil isn't just for breakouts, it can help with oil regulation, too. Look for scalp and hair products with the natural ingredient in them, or try adding a few drops to your scalp and rubbing it in before shampooing for extra cleansing.

Check the Ingredients

Some ingredients commonly found in hair care products—silicone, for instance—can lead to excess oil production. While this might be beneficial to those with dry scalps, for those with oily hair types, it's mostly likely unwanted. Look for ingredients like cyclomethicone and amodimethicone, which are silicones by another name.

Thoroughly Rinse Out Your Products

Excess product can weigh hair down, causing it to create more oil and to have lots of buildup. Take the time to rinse your shampoo, conditioner, or mask out of your hair completely to avoid this problem.

Wash and Style Hair Gently

Be careful when you wash, dry, and style the hair, as being too aggressive can cause hair to generate more oil. Just as you'll want to use gentle products, you'll also want to treat your hair and scalp gently.

Seek Professional Help

The good news is that most people find that as they get older, their hair will become less oily. This is because the body produces less of the androgen hormone as people age, which is responsible for oil production from head to toe. However, if you feel like your hair is getting more oily or not improving with any of the tips above, you may want to see a doctor to help determine the cause.

Seborrheic dermatitis or dandruff could be the culprit if you are also experiencing an itchy scalp and flakes. A doctor can prescribe a medicated shampoo that contains zinc pyrithione or ketoconazole to help get your scalp healthy.

A hormonal imbalance can also cause excess oil in your hair. Polycystic ovary syndrome is a hormonal disorder that can cause greasy hair, as well as acne and hair loss.
