Oily Hair: Causes, Remedies and Advice

Greasy hair is a common problem that can cause aesthetic discomfort and a dirty feeling even a few hours after washing. But what causes this phenomenon? Is it possible to reduce excess sebum and have fresh hair for longer? In this article, we will answer these questions and analyze the best strategies to combat greasy hair.

Why does hair become greasy?

The scalp is covered with sebaceous glands that produce sebum, a natural substance that protects and moisturizes the hair. However, when these glands produce too much sebum, the hair can appear greasy and weighed down.

The main causes of oily hair include:

1. Genetic predisposition

If your parents had oily hair, you are likely to have increased sebum production as well.

2. Washing too frequently

Washing your hair every day may seem like a logical solution, but it can actually make the problem worse. Using harsh shampoos can stimulate your scalp to produce even more oil in response.

3. Hormonal imbalances

During adolescence, pregnancy, or other stages of life characterized by hormonal changes, the body may produce more sebum than usual.

4. Unbalanced diet

A diet high in saturated fats and sugars can affect sebum production.

5. Excessive use of styling products

Gels, waxes, hairsprays and other products can build up on your scalp, weighing down your hair and promoting oiliness.

6. Stress and environmental factors

Chronic stress can alter sebum production, as can pollution and humidity.

Greasy hair and hair loss: is there a connection?

Many people wonder if greasy hair can cause hair loss. The answer is no, at least not directly. However, excess sebum can clog hair follicles, weaken hair, and cause hair loss in the long run. Additionally, if you tend to touch your hair often with dirty hands or wash it aggressively, you can contribute to the weakening of the hair shaft.

How to reduce excess sebum?

There are several strategies to reduce sebum production and keep hair fresh longer.

1. Don't wash your hair too often

Frequent washing can upset the balance of your scalp. If possible, try to reduce the frequency of washing and use dry shampoo between washes.

2. Avoid too hot water

Hot water stimulates sebum production, while warm or cold water helps keep hair fresh longer.

3. Limit the use of conditioners and masks

Conditioners and masks can weigh down your hair. If you use them, apply them only to the lengths and ends, avoiding the scalp.

4. Don't touch your hair too much

Your hands transfer dirt and natural oils to your hair, making it greasy. Avoid touching your hair too often.

5. Follow a balanced diet

A diet rich in B vitamins, zinc, and omega-3s can help rebalance sebum production.

6. Avoid excessive heat tools

Frequent use of straighteners, hair dryers and curling irons can stimulate the sebaceous glands. If possible, dry your hair at medium heat and limit the use of hot tools.

When to see a dermatologist?

If your hair is still excessively greasy despite adopting a proper routine, it may be useful to consult a dermatologist. In some cases, excessive oiliness may be linked to conditions such as seborrheic dermatitis or hormonal problems that require specific treatment.
