What Is Greasy Hair?
Greasy hair refers to hair that becomes oily and shiny soon after washing, often within 24 hours or less. The oiliness is caused by an overproduction of sebum, the natural oil secreted by the sebaceous glands in the scalp. While some sebum is necessary to lubricate and protect the hair, excess sebum can make the hair look limp, stringy, and dirty.
Greasy hair is a common problem that affects people of all ages and hair types. It can be frustrating to deal with, as it requires frequent washing and styling to keep the hair looking clean and fresh. However, with the right shampoo and hair care routine, it is possible to manage greasy hair and achieve a healthy, balanced scalp.
What Causes Greasy Hair?
There are several factors that can contribute to greasy hair:
Overactive Sebaceous Glands
The primary cause of greasy hair is overactive sebaceous glands in the scalp. These glands produce sebum, which is a natural oil that lubricates and protects the hair and scalp. However, some people’s sebaceous glands produce too much sebum, leading to oily hair.
Hormonal Changes
Hormonal fluctuations can also affect sebum production. During puberty, pregnancy, and menopause, the body undergoes hormonal changes that can stimulate the sebaceous glands and cause greasy hair. Certain medications, such as birth control pills and testosterone supplements, can also alter hormone levels and contribute to oily hair.
Genetics
Some people are genetically predisposed to having overactive sebaceous glands and producing more sebum than others. If one or both parents have greasy hair, their children are more likely to have it as well.
Stress
Stress can trigger the production of androgens, which are hormones that stimulate the sebaceous glands and increase sebum production. When a person is under stress, their body releases cortisol, which can also lead to oily hair.
Diet
A diet high in processed foods, sugar, and unhealthy fats can contribute to greasy hair. These foods can cause inflammation in the body and disrupt hormone balance, leading to increased sebum production.
Environmental Factors
Hot and humid weather can make greasy hair worse, as sweat and humidity can mix with sebum and make the hair look oilier. Pollution and hard water can also contribute to greasy hair by leaving residue on the scalp and hair.
Overwashing
While it may seem counterintuitive, washing your hair too frequently can actually make it greasier. When you wash your hair, you strip away the natural oils that protect it. In response, the sebaceous glands produce even more sebum to compensate for the loss of oil. This can lead to a vicious cycle of overwashing and increased oil production.
How Do You Choose the Right Shampoo Formula for Greasy Hair?
Choosing the right shampoo formula is key to managing greasy hair. Here are some factors to consider when selecting a shampoo for oily hair:
Look for Clarifying or Volumizing Formulas
Clarifying shampoos are designed to deep clean the hair and scalp, removing excess oil, product buildup, and impurities. They typically contain stronger surfactants than regular shampoos, which can help to break down and wash away sebum. Volumizing shampoos are also a good choice for greasy hair, as they can help to lift the hair at the roots and create the illusion of fuller, less oily hair.
Avoid Heavy, Moisturizing Formulas
While moisturizing shampoos can be beneficial for dry or damaged hair, they can make greasy hair worse. Heavy, creamy formulas can weigh down the hair and make it look even oilier. Instead, opt for lightweight, gel-based or clear shampoos that won’t leave residue on the hair.
Check the Ingredients List
When shopping for a shampoo for greasy hair, look for ingredients that can help to regulate sebum production and keep the scalp balanced. Some beneficial ingredients to look for include:
- Salicylic acid: This beta-hydroxy acid can help to exfoliate the scalp and unclog hair follicles, reducing excess oil production.
- Tea tree oil: This essential oil has antimicrobial and anti-inflammatory properties that can help to soothe the scalp and regulate sebum production.
- Peppermint oil: This refreshing essential oil can help to stimulate blood flow to the scalp, promoting healthy hair growth and reducing oiliness.
- Clay: Kaolin and bentonite clays can help to absorb excess oil and impurities from the scalp and hair.
- Aloe vera: This soothing plant extract can help to balance the scalp’s pH level and reduce inflammation, which can contribute to oily hair.
Avoid shampoos that contain heavy oils, silicones, or waxes, as these ingredients can build up on the hair and make it look greasier.
Consider Your Hair Type
While greasy hair is a common problem, not all oily hair is the same. Different hair types may require different shampoo formulas to manage oiliness effectively. Here are some tips for choosing a shampoo based on your hair type:
- Fine hair: Look for volumizing shampoos that can help to lift the hair at the roots and create the illusion of fuller, less oily hair. Avoid heavy, moisturizing formulas that can weigh down fine hair.
- Thick hair: Choose a clarifying shampoo that can penetrate through thick hair and effectively remove excess oil and buildup. Look for formulas that contain salicylic acid or other exfoliating ingredients to help unclog hair follicles.
- Curly hair: Curly hair tends to be drier than straight hair, so it may not require as frequent washing. Look for gentle, sulfate-free shampoos that can cleanse the scalp without stripping the hair of its natural oils.
- Color-treated hair: If you have color-treated hair, choose a shampoo that is specifically formulated for colored hair. These shampoos are typically gentler and less stripping than regular shampoos, which can help to preserve your hair color while managing oiliness.

How Should You Properly Use Shampoo for Greasy Hair?
Using shampoo properly is just as important as choosing the right formula for greasy hair. Here are some tips for shampooing oily hair effectively:
Focus on the Scalp
When shampooing greasy hair, it’s important to focus on the scalp rather than the ends of the hair. The scalp is where excess oil is produced, so that’s where you should concentrate your cleansing efforts. Use your fingertips to massage the shampoo into your scalp, using circular motions to stimulate blood flow and loosen any buildup.
Rinse Thoroughly
After massaging the shampoo into your scalp, be sure to rinse it out thoroughly. Any leftover shampoo can leave a residue on your hair, making it look and feel greasier. Use cool or lukewarm water to rinse, as hot water can stimulate the sebaceous glands and increase oil production.
Don’t Overwash
While it may be tempting to wash your hair every day if it’s prone to oiliness, overwashing can actually make the problem worse. When you strip your hair of its natural oils too frequently, your sebaceous glands may go into overdrive to compensate, producing even more oil. Try to wash your hair every other day or every three days, depending on your hair type and the severity of your oiliness.
Use Dry Shampoo Between Washes
If your hair starts to look greasy between washes, try using a dry shampoo to absorb excess oil and refresh your hair. Dry shampoo is a powder or spray that can be applied to the roots of your hair to soak up oil and add volume. Look for a dry shampoo that is specifically formulated for oily hair, and be sure to brush it through your hair thoroughly to distribute the product evenly.
Don’t Condition Your Scalp
While conditioning your hair is important for keeping it soft and manageable, you should avoid applying conditioner directly to your scalp if you have greasy hair. Conditioner can weigh down your hair and make it look oilier, especially if it’s applied too close to the roots. Instead, focus on conditioning the ends of your hair, where it tends to be drier and more prone to damage.
Hair Care Tips to Help You Better Manage Greasy Hair
In addition to using the right shampoo and shampooing techniques, there are several other hair care tips that can help you manage greasy hair more effectively:
Use a Boar Bristle Brush
Boar bristle brushes are great for distributing your hair’s natural oils from the scalp to the ends of your hair. This can help to keep your hair looking shiny and healthy without making it look greasy. Look for a brush with natural boar bristles, and use it to brush your hair from root to tip every day.
Avoid Touching Your Hair
Your hands can transfer oil and dirt to your hair, making it look greasier than it actually is. Try to avoid touching your hair throughout the day, especially if you have a habit of playing with your hair or running your fingers through it.
Use a Clarifying Treatment Once a Month
Even if you use a clarifying shampoo regularly, it’s a good idea to do a deep clarifying treatment once a month to remove any buildup that may have accumulated on your scalp and hair. Look for a clarifying mask or treatment that contains ingredients like clay, charcoal, or apple cider vinegar to help detoxify your hair and scalp.
Eat a Healthy Diet
What you eat can have a big impact on the health of your hair and scalp. A diet that is high in processed foods, sugar, and unhealthy fats can contribute to excess oil production and inflammation in the body. On the other hand, a diet that is rich in fruits, vegetables, lean proteins, and healthy fats can help to keep your hair and scalp healthy and balanced. Some specific foods that may help to reduce oiliness include:
- Leafy greens: Spinach, kale, and other leafy greens are rich in vitamins A and C, which can help to regulate sebum production and keep your scalp healthy.
- Nuts and seeds: Almonds, walnuts, and flaxseeds are high in omega-3 fatty acids, which can help to reduce inflammation in the body and keep your hair and scalp healthy.
- Whole grains: Brown rice, quinoa, and other whole grains are rich in B vitamins, which can help to strengthen your hair and reduce oiliness.
- Lean proteins: Chicken, fish, and tofu are all good sources of protein, which is essential for healthy hair growth and can help to balance oil production in the scalp.
Manage Stress
Stress can have a big impact on the health of your hair and scalp. When you’re stressed, your body produces more androgens, which can stimulate the sebaceous glands and increase oil production. To help manage stress and keep your hair and scalp healthy, try incorporating some stress-reducing activities into your daily routine, such as:
- Exercise: Regular exercise can help to reduce stress and improve circulation, which can benefit your hair and scalp.
- Meditation: Taking a few minutes each day to meditate or practice deep breathing can help to calm your mind and reduce stress.
- Sleep: Getting enough sleep is essential for overall health and can help to reduce stress and balance hormones.
- Self-care: Taking time for yourself to do things you enjoy, whether it’s reading a book, taking a bath, or spending time with friends and family, can help to reduce stress and promote overall well-being.
What Are Some DIY Solutions and Natural Alternatives for Greasy Hair?
If you prefer to use natural or DIY solutions for your greasy hair, there are several options to try:
Apple Cider Vinegar Rinse
Apple cider vinegar is a natural clarifier that can help to remove buildup and excess oil from your hair and scalp. To use it as a rinse, mix equal parts apple cider vinegar and water in a spray bottle. After shampooing your hair, spray the mixture onto your scalp and hair, focusing on the roots. Let it sit for a few minutes, then rinse it out thoroughly with cool water.
Baking Soda Scrub
Baking soda is another natural clarifier that can help to absorb excess oil and remove buildup from your hair and scalp. To use it as a scrub, mix equal parts baking soda and water to form a paste. Massage the paste into your scalp and hair, focusing on the roots. Let it sit for a few minutes, then rinse it out thoroughly with cool water.
Lemon Juice Rinse
Lemon juice is a natural astringent that can help to balance the pH of your scalp and reduce excess oil production. To use it as a rinse, mix the juice of one lemon with a cup of water. After shampooing your hair, pour the mixture over your scalp and hair, focusing on the roots. Let it sit for a few minutes, then rinse it out thoroughly with cool water.
Aloe Vera Gel Mask
Aloe vera gel is a natural moisturizer that can help to soothe and balance the scalp, reducing excess oil production. To use it as a mask, apply a generous amount of pure aloe vera gel to your scalp and hair, focusing on the roots. Let it sit for 20-30 minutes, then rinse it out thoroughly with cool water.
Essential Oils
Certain essential oils can help balance sebum production and keep the scalp healthy, which may reduce oiliness. Some of the best essential oils for greasy hair include:
- Rosemary essential oil: Rosemary oil can help stimulate the scalp and regulate sebum production. A 2015 study found that rosemary oil was just as effective as minoxidil, a common hair growth drug, in improving hair growth in people with androgenetic alopecia (male or female pattern baldness)[4].
- Peppermint essential oil: Peppermint oil has a cooling, tingling effect on the scalp that can help stimulate blood flow and unclog hair follicles. A 2014 animal study found that peppermint oil promoted hair growth more effectively than minoxidil[4].
- Lemon essential oil: Lemon oil has astringent properties that can help control excess oil production on the scalp. A 2017 study found that lemon oil helped reduce dandruff and improve the overall health of the scalp[5].
To use essential oils for greasy hair, mix a few drops of your chosen oil with a carrier oil like jojoba or coconut oil, and massage it into your scalp before shampooing. You can also add a few drops of essential oil to your shampoo or conditioner.
Apple Cider Vinegar Rinse
Apple cider vinegar (ACV) is a popular natural remedy for greasy hair. Its acidic properties can help balance the pH of the scalp, which may reduce excess oil production. ACV also has antimicrobial properties that can help keep the scalp clean and healthy.
To make an ACV rinse, mix equal parts water and raw, unfiltered apple cider vinegar in a spray bottle. After shampooing, spray the mixture onto your scalp and hair, focusing on the roots. Let it sit for a few minutes, then rinse it out with cool water.
Aloe Vera Gel
Aloe vera gel is a natural moisturizer that can help soothe and hydrate the scalp without adding excess oil. It also contains enzymes that can help gently exfoliate the scalp, removing dead skin cells and product buildup that can contribute to oiliness.
To use aloe vera gel for greasy hair, massage a small amount of pure aloe vera gel into your scalp and hair before shampooing. Let it sit for 10-15 minutes, then rinse it out and shampoo as usual.
What Common Mistakes Should You Avoid With Greasy Hair?
While there are many effective ways to manage greasy hair, there are also some common mistakes that can make the problem worse:
Overwashing
As mentioned earlier, washing your hair too frequently can strip away the natural oils that protect your scalp, causing your sebaceous glands to produce even more oil to compensate. Try to limit washing to every other day or every three days, depending on your hair type and the severity of your oiliness.
Using Hot Water
Hot water can stimulate the sebaceous glands and increase oil production. When washing your hair, use lukewarm or cool water instead of hot water to help keep your scalp balanced.
Applying Conditioner to the Scalp
Conditioner is designed to moisturize the ends of your hair, not your scalp. Applying conditioner directly to your scalp can weigh down your hair and make it look greasier. Instead, focus on applying conditioner to the mid-lengths and ends of your hair.
Using Heavy, Oil-Based Products
Hair products that contain heavy oils or waxes can build up on the hair and scalp, making greasy hair worse. Avoid using products that contain mineral oil, petroleum, or silicones, as these ingredients can be difficult to wash out and can contribute to oiliness.
Touching Your Hair Frequently
Your hands can transfer oil and dirt to your hair, making it look greasier than it actually is. Try to avoid touching your hair throughout the day, and if you must touch it, make sure your hands are clean.
Avoiding common mistakes and incorporating the hair care tips and DIY solutions mentioned above can help you manage greasy hair and achieve a healthy, balanced scalp. Remember, everyone’s hair is unique, so it may take some trial and error to discover the right combination of products and techniques that work best for you. Be patient, and don’t hesitate to experiment until you find your perfect hair care routine.
