Have you been having greasy hair troubles? Handling greasy hair can often make us annoyed and uncomfortable. Before you can flaunt your clean and fresh hair, your oily hair is already waving at you. You may even find it hard to experiment with new hairstyles or products. So, today, let’s get that out of the way, shall we?

What causes greasy hair?

The sebaceous glands in your scalp produce sebum to keep your hair healthy, smooth and prevent it from drying out and breaking. When these glands get overactive, it can cause your hair to look greasy, and you could get dandruff too. It can happen for various reasons like an improper hair wash routine, the wrong hair care products, certain medical conditions, food habits, and more. 

How can you prevent greasy hair?

The good thing is that you don’t have to live with it! There is plenty you can do to avoid that grease in your hair.

1. Choose the right hair care products 

Like your skin, there are different hair types too. Hence, you need to opt for products that are suitable for thin hair that tends to be greasy.

2. Eat healthy

Other than the products that you use, what you eat also reflects on your hair. Therefore, it is vital to consume a lot of fruits and veggies. Stay away from oily snacks and junk food, as they can affect the health of your hair. 

3. A hair wash routine for greasy hair type

Depending on your hair, create a hair wash routine. For instance, over-washing oily hair to eliminate oil can cause extra sebum or oil production. It is best not to wash your hair every day; instead, 2-3 times a week should be ideal as doing this can help balance oil production and reduce greasiness.

4. Don’t touch your hair!

Try not to touch your hair! Don’t do it! By touching your hair frequently, you can transfer dirt, germs, and oil into it. 

5. Say NO to obsessive hair brushing 

Brushing your hair is excellent. Don’t get us wrong. It improves blood circulation to your scalp, making it healthy and beautiful. However, there’s a thin line between brushing and over-brushing your hair. You don’t have to comb your hair fifty times a day. Maybe just once or twice.

6. Limit your hair care products 

Don’t use too much product on your hair. Rather than buying multiple products on impulse, stick to a limited number of products that are absolutely important for your hair. 

7. Use your conditioner wisely

Apply conditioner only to the ends of your hair to keep them from drying out. Make sure to rinse thoroughly after application. Never apply it throughout your hair, as this can make it greasy. Also, avoid putting conditioner close to your roots as this will make your hair flat and oily quickly.

8. Limit styling your hair with heat

It is best to minimise styling your hair through blow drying, straightening, or curling as they can also give you greasy hair. Avoiding them will also protect hair from heat damage. 

Try to allow your hair to air dry naturally.

9. Wear your hair up 

You may love leaving your hair open, but that can also make it sweaty and greasy. Therefore, sometimes try to tie a ponytail or make a cute bun. You can experiment with various hairstyles like pineapples and braided buns. However, that doesn’t mean you need to always have it tied up. Switch between leaving it open and tying it rather than opting for one particular hairstyle. 

When Should You See a Doctor?

Usually, it is possible to prevent greasy hair by taking care of your hair and taking precautions. If you feel you have done almost everything and still see no difference, talk to a dermatologist. There could be various reasons, including underlying medical conditions causing greasy hair. A doctor can evaluate your situation and share varied treatment options that could work for you. 


1. Why is my hair greasy after one day of washing it?

With every person, the reasons could vary. It could be due to hygiene issues, the wrong choice of products or even overwashing. You can take some help from a dermatologist who will offer you the best solution for your hair issues. 

2. What happens if you do not wash your hair for a week?

It can lead to product build-up on your scalp, along with dirt and dust. Eventually, affecting your hair growth, causing hair fall and other forms of hair damage.

3. Can apple cider vinegar get rid of greasy hair?

It is one of the more popular natural remedies to deal with greasy hair. However, there’s no medical evidence to substantiate this statement.

4. Is it bad to have oily hair?

There’s nothing terrible about oily hair as it is a hair type precisely like the other types. Though, it could be challenging to deal with it. You can follow the tips and things mentioned above to prevent greasy hair.
