An oily scalp refers to a condition where the skin on the top of the head produces excessive sebum, the natural oil produced by the sebaceous glands. Sebum is crucial in maintaining the hair’s health and scalp by providing moisture and protection. However, when the sebaceous glands become overactive, they can produce more sebum than necessary, leading to an oily scalp. On the scalp and face, in particular, sebaceous glands are more prevalent in humans than anywhere else except the palms of the hands and soles of the feet.
What are the Causes that make the scalp Oily?
An oily scalp can be attributed to various factors, including genetic predisposition, hormonal changes, lifestyle choices, and environmental conditions. Here are a few common causes why your scalp could be oily:
- Genetics: Your skin type and the activity of your sebaceous glands are significantly influenced by genetic factors. If your family members have a history of oily skin or scalp, you might also be more prone to having an oily scalp.
- Hormonal Changes: Fluctuations in hormones, particularly during puberty, pregnancy, menstruation, and menopause, can influence sebum production. Androgens, or male hormones, can cause the sebaceous glands to generate more oil in both men and women.
- Overactive Sebaceous Glands: Sebum, a natural oil produced by overactive sebaceous glands, hydrates the scalp and hair. Overactive sebaceous glands can produce excessive sebum, resulting in an oily scalp.
- Hygiene Habits: Over washing your hair or using harsh shampoos can strip away natural oils, prompting the scalp to produce more sebum to compensate. On the other hand, inadequate cleansing can accumulate dirt, sweat, and excess oil.
- Humidity and Weather Conditions: Hot and humid weather can trigger the sebaceous glands to generate more oil. The excess moisture in the air can exacerbate the oiliness of the scalp.
- Stress: High-stress levels can trigger hormonal changes that affect sebum production. Stress can also lead to habits like touching your hair and scalp more frequently, which can transfer oil and dirt.
- Diet: A diet high in greasy and fried foods and dairy products can produce excessive sebum. However, the relationship between diet and oily scalp must be fully understood and can vary among individuals.
- Incorrect Hair Care Products: Using hair care products that are too heavy or unsuitable for your hair type can weigh down the hair and make the scalp oilier. Conditioners applied directly to the scalp can also contribute to excess oil.
- Overbrushing: Brushing your hair too frequently can stimulate the scalp, leading to oil distribution from the scalp to the hair strands.
- Medications and Medical Conditions: Some medical conditions, like PCOS and hormonal imbalances, can enhance oil production. Some medications, such as corticosteroids, can also influence sebum secretion.
- Overuse of Styling Products: More styling products, like gels, mousses, and sprays, can build up on the scalp and hair, trapping oil and making the scalp appear greasier.
What to Look for in Haircare Products to Prevent Excess Oil
Choosing the right hair care products can play a significant role in managing excess oil on the scalp. Consider the following important aspects while choosing products to avoid having an oily scalp:
- Shampoo Type: Look for shampoos labeled as “clarifying,” “balancing,” or “oil-control.” These formulations help regulate sebum production and remove excess oil without over-drying the scalp. Avoid shampoos with heavy moisturizing or hydrating properties, as they can exacerbate oiliness.
- Sulphate-Free Formulas: Go for sulphate-free shampoos. Sulfates are abrasive cleaning products that can remove natural oils, causing the scalp to produce more oil.
- pH-Balanced Products: Choose products with a pH level close to the scalp’s natural pH (around 4.5 to 5.5). pH-balanced products can help maintain a healthy scalp environment.
1. Ingredients to Look For
- Salicylic acid: This ingredient helps exfoliate the scalp, eliminating dead skin cells and additional oil.
- Tea tree oil: It can assist in regulating oiliness and preserving the scalp’s health because of its antibacterial characteristics.
- Witch hazel: It can act as an astringent, helping to balance oil production.
- Niacinamide: This form of vitamin B3 can regulate sebum production and soothe the scalp.
2. Avoid Heavy Conditioners on the Scalp
Apply conditioner primarily to the lengths and ends of your hair, avoiding the scalp area. This prevents excess product buildup on the scalp.
3. Look for Non-Comedogenic Formulas
A non-comedogenic product is one that won’t clog pores, so choose those with that label. In particular, the health of the scalp may benefit from this.
4. Frequency of Use
Use hair care products as needed but avoid over-washing your hair. Washing too frequently can strip the scalp of natural oils, triggering more oil production.
5. Dermatologist-Recommended Products
If you’re struggling with excessive oiliness, consider consulting a dermatologist. They can recommend products tailored to your specific scalp condition. Before utilizing a new product, do a patch test to guarantee you don’t have any adverse effects. You should test the product on a tiny patch of your scalp and wait 24 hours to see if it causes any irritation.
Everyone’s scalp is unique, so finding the right products that work for you might take trial and error.

Final Thoughts
An oily scalp is a condition where the sebaceous glands on the scalp produce an excess amount of sebum, the natural oil that helps moisturize and protect the scalp and hair. While sebum is essential for maintaining healthy hair, excessive production can lead to issues like greasiness, flat hair, and discomfort. Several factors contribute to an oily scalp, including genetics, hormonal changes, diet, hygiene practices, and environmental factors.
