Oily hair is often due to excessive sebum production by the scalp.

This can be caused by over-washing, which strips natural oils and prompts more sebum production.

Certain hair products might also increase oiliness.

Lifestyle factors like stress, hormonal changes, and poor diet can further affect sebum levels.

Understanding these causes is key to finding solutions for balanced, healthy hair.

Major Causes Of Increased Oil Production

Understanding the major causes of increased oil production can help you better address the issue of oily hair.

Here are some common factors that can contribute to excessive sebum production:


Washing your hair too frequently can strip away the natural oils, leading to an overproduction of sebum as your scalp tries to compensate.1

Aim to wash your hair every other day or every few days to maintain a healthy balance.

Harsh Hair Products

Certain hair care products, such as shampoos and conditioners, may contain ingredients that can irritate the scalp and trigger an increase in oil production.

Look for products labeled "oil-free" or "suitable for oily hair" to avoid exacerbating the issue.

Hormonal Changes

Hormonal fluctuations, such as those that occur during puberty, pregnancy, or menopause, can disrupt the oil balance on your scalp and contribute to oily hair.2

If you suspect hormonal imbalances, consult with a healthcare professional for further guidance.

Unhealthy Diet

Poor nutrition can impact the health of your hair and scalp, leading to increased oil production.

A diet high in processed foods and saturated fats can contribute to oily hair.

Opt for a balanced diet rich in fruits, vegetables, lean proteins, and healthy fats to support overall hair health.


Stress has a profound impact on our body, including our hair and scalp.

High stress levels can disrupt hormonal balance, leading to an increase in sebum production.

Engaging in stress management techniques, such as exercise, meditation, and relaxation techniques, can help reduce the impact of stress on your hair.

Hormonal Imbalances And Oily Hair

Hormonal imbalances are a key factor in excessive scalp oil production, often leading to oily hair.

This is especially common during puberty, pregnancy, and menopause due to significant hormonal changes.

If hormonal imbalances are suspected, consulting a healthcare professional for hormone level evaluation and treatment is advisable.

Addressing these imbalances, along with stress management and a healthy lifestyle, can improve hair health.

Treating the root cause, rather than just external symptoms, is essential for long-term management of oily hair.

The Impact Of Stress On Your Hair's Oil Content

Stress significantly affects our health, including increasing our hair's oiliness.

High stress levels lead to elevated cortisol, the stress hormone, which can disrupt hormonal balance and increase sebum production on the scalp.3

This excess sebum results in greasy, oily hair.

Stress not only directly stimulates oil production but also causes hormonal imbalances that exacerbate the issue.

To combat stress-related oily hair, incorporating stress management techniques into your daily life is crucial.

Regular exercise, meditation, deep breathing exercises, and relaxation activities can reduce stress levels, promoting hormonal balance and healthier hair.

Environmental Factors That Contribute To Oiliness

In addition to internal factors such as hormonal imbalances and lifestyle habits, environmental factors can also contribute to the oiliness of your hair.

It's important to take into account these external influences when trying to address and manage oily hair.

Here are some environmental factors that may contribute to excess oil production:


High humidity levels can cause your hair to become frizzy and appear greasy.

When the air is humid, moisture in the air can penetrate the hair shaft, causing the hair to swell and become more susceptible to oil buildup.

To combat the effects of humidity, try using products that are specifically formulated to control excess oil and provide humidity protection.

Pollution in the environment can contribute to the oiliness of your hair.

Airborne pollutants, such as dust and smoke, can settle on your scalp and mix with sebum, leading to a greasy appearance.

To minimize the impact of pollutants on your hair, it's important to cleanse your hair and scalp regularly using gentle, clarifying shampoos that can effectively remove impurities.

Heat Styling

Excessive heat styling, such as blow-drying, straightening, or curling, can also lead to greasy hair.

Heat can stimulate the oil glands on the scalp, causing an increase in oil production.

Additionally, the use of heavy styling products and serums can also contribute to oiliness.

When using heat styling tools, it's important to use heat protectant products and avoid applying excessive styling products to the roots of your hair.


Brushing your hair excessively or vigorously can stimulate the oil glands on your scalp, leading to increased oil production.

Opt for a gentle brush or comb to avoid overstimulating the oil glands and distributing the oils evenly throughout your hair.
