An oily scalp is a common condition characterized by excessive sebum production from the scalp’s sebaceous glands. This can make hair look greasy, heavy and difficult to manage, affecting not only appearance but also overall scalp health. In this article we examine the main causes, effective remedies and the best products to manage an oily scalp professionally.
What causes an oily scalp?
An oily scalp results from sebum overproduction, often due to a combination of internal and external factors. Here are the main ones:
1. Genetic factors
Genetic predisposition plays a significant role. If one or both parents have an oily scalp, the issue is likely to appear in their children as well.
2. Hormonal imbalances
Hormonal fluctuations, such as those during puberty, pregnancy or the menstrual cycle, can overstimulate the sebaceous glands.
3. Diet and stress
- A diet high in fats and sugars can contribute to sebum overproduction.
- Chronic stress can negatively affect scalp health, worsening the condition.
4. Inadequate products
Using shampoos that are too aggressive or not suited to your scalp type can make the situation worse, causing a rebound effect (further stimulation of the sebaceous glands).
Main symptoms of an oily scalp
- Greasy appearance: Hair that looks dirty just a few hours after washing.
- Itching: Caused by sebum build-up on the scalp.
- Loss of volume: Hair appears flat and weighed down.
- Risk of oily dandruff: Excess sebum promotes the growth of yeasts like Malassezia, which can cause dandruff.

Remedies and solutions for an oily scalp
1. Targeted shampoos
Choose shampoos with purifying and sebum-regulating ingredients such as:
- Green clay: Helps remove excess sebum.
- Zinc: Counters inflammation and reduces sebum production.
- Green tea or mint extracts: Provide a refreshing, purifying sensation.
If your scalp is also sensitive, opt for gentle formulas. Learn more in our article: Sensitive Scalp: How to Soothe Irritation and Redness.
2. Scalp masks
Apply a purifying scalp mask once a week to remove residues and regulate sebum. Clay or activated charcoal masks are particularly effective.
3. Avoid washing too often
Washing hair daily can make the problem worse. Try to limit washes to 2–3 times per week and use a dry shampoo to keep hair feeling fresh between washes.
4. Adjust your diet
- Increase foods rich in omega-3s, like salmon and walnuts, to improve the scalp’s lipid balance.
- Reduce sugars and fatty foods to avoid excessive sebum production.

5. Avoid direct heat
Frequent use of hair dryers or flat irons can further stimulate the sebaceous glands. Dry hair at medium temperature and limit the use of heat styling tools.
