What Causes Greasy Hair?

In our hair scalp, there is an oil-producing gland called “Sebaceous”. Greasy hair is the result of the oil produced by the Sebaceous gland. Normally, this oil is nourishing for hair and it makes hair more luscious and stronger.

There are various types of hair texture like coarse hair, thick or thin hair. Those who have coarse or thick hair, often don’t face this greasy hair problem. Those who have fine thin hair, face the greasy roots problem most. 

When your overactive Sebaceous gland produces oil and your hair can’t absorb it, then it leads to oil build-up which causes greasy hair. Now, if you tend to wash your hair often for this greasy hair problem, then you’re doing wrong. Because the more you wash your hair, the more the oil gland produces the oil to keep balance. 

Here are some reasons identified and described by hair experts which causes “my hair gets greasy after 1 day”-

1. Using Wrong Shampoo

Using the wrong shampoo can be the main factor for greasy hair. Try to use mild & gentle shampoo, not too hydrating or not so dry that can strip the natural oil. Experts advise avoiding shampoo that is labeled as “dry”, ” damaged”, “glossy” or “smooth”. 

These work fine, but these aren’t good for greasy hair. However, hair professionals say that, if you have a greasy hair problem, you better use purifying or clarifying shampoo to get rid of the product build-up. These shampoos work as deep-cleanser and remove the excess oil.

2. Too Much Conditioner

After using the conditioner, instantly our hair feels so soft and smooth that we just can’t help to use conditioner more. But, that’s a big NO. It’s directed to use conditioner at the end strands of your hair, not on the top. Some of us have very dry hair, so we use conditioner on the top to detangle our hair. The more upward you’ll use the conditioner, the more you’ll notice the greasiness. 

3. Applying Excessive Oil 

Using oil or serum too much can make your hair feel or look oily even after washing. So, apply a modest quantity of oil, not too much, not too less. Too much oil can’t be absorbed inside the roots, so it becomes dirty and later difficult to wash away. 

4. Product-Build Up

If our hair isn’t well-washed with water, then the shampoo, conditioner, or oil can gradually build up at the roots which result in greasy hair. So, wash your hair with a generous amount of water after shampoo and conditioning. If you want to get rid of the product build-up, then use apple cider vinegar with water to remove the build-up.

Apple cider vinegar with water helps to get rid of product build-up as well as kill bacteria in the scalp. 

5. Not Washing Hair-Styling Tools Often 

Hairbrushes bear our dead scalp cells and dirt of hair plus the outside dust. So, if you haven’t washed your hairbrush often or ever, use warm water to wash the hairbrush. Clean your hair straightener with a damp cloth and let it air-dry. It’ll help to prevent the build-up. 

6. Using Hot Water In Hair

Washing hair with hot water stimulates the Sebaceous gland and it produces more than oil then. So, try to use cold water or lukewarm water to wash your hair.

7. Hormones 

When you are stressed, going through puberty or menopause, then changing of hormones can affect the oil gland, more oil produces. If you are in menstruation, then the increase of progesterone hormone triggers sebum production. 

8. Over Shampooing Your Hair

My mom thinks if I don’t wash my hair regularly, my head will heat up. Many people think like this and wash their hair regularly. If you wash your hair regularly, it increases the sebum production to keep a balance. Try to wash your hair twice or thrice a week. If you sweat a lot, then you’ve to wash your hair often but cut down the shampooing often. 

9. Touching Hair Too Often 

Touching hair feels good, but if you touch it often, the oil and dirt from the hand transfer into the hair which results in product build-up again.

10. Wash Pillowcase Timely 

One should be careful about sleeping habits. Wash your pillowcase often and timely if you want to get rid of the product build-up.
