Causes of increased sebum production on the scalp

Excessive sebum production on the scalp is a common problem that can affect the appearance of the hair, its health and overall comfort. This excessive sebum production can have several causes, some of which are natural, others may be the result of poor hair care or external factors. In this article, we will look at the main causes that can lead to excessive sebum production on the scalp.
1. Hormonal changes
One of the most common causes of excess sebum production is hormonal changes. During puberty, pregnancy, menstruation, or when taking birth control, hormones can affect the activity of the sebaceous glands. Increased production of androgenic hormones (such as testosterone) leads to increased sebum production, which can affect the scalp and other areas of the body.
2. Insufficient drinking regimen
Adequate fluid intake is essential for skin health, including the scalp. A lack of water can cause the skin to lose moisture, leading to overloading of the sebaceous glands, which begin to produce more sebum to compensate for dehydration. This can lead to oily hair and a feeling of heavy, weighed down curls.
3. Skin damage from lighteners
Using chemical hair products, such as lighteners or strong dyes, can damage the scalp. Lighteners that are aggressive on the hair can disrupt the protective layer of the skin, leading to irritation and subsequent increased sebum production. The skin tries to restore balance and naturally responds by producing more sebum.
4. Impermeable layer of silicones
Some styling products, shampoos or conditioners may contain silicones, which create an impermeable layer on the scalp. This layer prevents the skin from breathing naturally, which leads to clogged pores and an imbalance of sebum. The result can be excessive sebum production, which makes the skin feel oily.
5. Low-quality cosmetics
Using low-quality cosmetics that contain harsh or poor-quality ingredients can also affect the condition of the scalp. Some cheap products may contain parabens, sulfates, silicones, and other chemicals that weigh down the scalp, thereby increasing sebum production.
6. Hard water
Hard water is commonly available in the Czech Republic and contains high amounts of minerals such as calcium and magnesium. These minerals settle on the scalp and hair, which can cause them to become clogged and impair the absorption of nutrients. The polluted scalp then starts to produce more sebum, which leads to oily hair and a poor appearance.
7. Stress and unhealthy lifestyle
Psychological factors such as stress, anxiety or insomnia can also affect sebum production. During times of stress, the body produces more cortisol, which can stimulate the sebaceous glands and lead to oily skin. In addition to stress, an unhealthy lifestyle also plays a role - a poor diet, lack of exercise or smoking can negatively affect the appearance of the scalp.
8. Hereditary factors
Genetics can also play a role in how active your sebaceous glands are. If you have someone in your family who tends to have oily skin, it's likely that you will also tend to produce more sebum.
9. Not drying out the scalp and letting the hair dry naturally

Another factor that can contribute to excess sebum production on the scalp is not drying the scalp and letting the hair dry naturally. If you don’t dry it enough or dry it too slowly, the hair can remain damp for a long time, creating an ideal environment for bacteria and yeast to overgrow on the scalp. This microbial growth can then stimulate the sebaceous glands to produce more sebum, resulting in oily hair and an uncomfortable scalp sensation.

Additionally, if hair is left damp for a long time, it can disrupt the natural balance of the skin, causing inflammation or irritation. In this case, the scalp may start to defend itself by producing excess sebum to protect its layer.

The ideal solution is to gently towel dry your hair and then use a blow dryer on a medium heat setting to dry your hair effectively but without overheating your scalp. However, drying your hair too often or for too long at high temperatures can actually dry out your scalp and stimulate it to produce even more sebum, which is important to keep in mind.


Increased sebum production on the scalp is a problem that can have many causes. The most common factors include hormonal changes, insufficient drinking regimen, skin damage from lighteners, use of low-quality cosmetics and hard water. To solve this problem, it is important to choose the right hair and scalp care, use gentle products and pay attention to a healthy lifestyle. If you suspect more serious problems, it is a good idea to consult a dermatologist, who can recommend specific procedures to eliminate this problem.
