Why do we have greasy hair?

Introduction :

Oily hair is a common problem that can be both embarrassing and frustrating. If you are wondering why you have oily hair , this article will provide you with the information you need to understand the causes of this phenomenon.

First of all, it is important to understand that oily hair is caused by excess sebum production.

What is sebum?

Sebum is an oily substance produced by sebaceous glands located just below the surface of your skin. These sebaceous glands are found throughout your body, but are most numerous on your scalp , face, chest, and back.

1 - Where does sebum come from?

Sebum is produced by sebaceous cells , which are found inside the sebaceous glands . Sebaceous cells produce lipids, an oily substance that is then secreted into the ducts of the sebaceous glands . The sebum then mixes with sweat and other substances to form the hydrolipidic film, a protective layer that covers your skin.

2 - What is sebum used for?

Sebum has several important functions for the health of skin and hair. It helps maintain a protective barrier for the skin, which prevents water loss and protects against bacteria and other pathogens. Sebum also nourishes the hair, keeping it supple and hydrated -.

3 - What's the problem with sebum?

Excessive sebum production can cause skin and hair problems, such as oily hair , dandruff , clogged pores, and acne . It is therefore important to maintain a healthy balance of sebum production to keep your skin and hair healthy.

- Genetic factors :

Some people are simply predisposed to having excess sebum production due to their genetics. If your parents have oily hair or skin , you may have it too.

- Hormonal changes : Hormones have a significant impact on sebum production. Hormonal changes that occur during puberty, pregnancy, menopause or the menstrual cycle can cause excess sebum production.

- Stress :

Stress can also affect hormone levels and lead to excess sebum production. Stress hormones such as cortisol can stimulate sebum production, which can lead to oilier skin or hair .

- Food :

A diet high in saturated fat, sugar and salt can disrupt hormonal balance and contribute to excess sebum production. Similarly, excessive alcohol and caffeine consumption can also stimulate sebum production.

- Hair and skin care products :

Using the wrong products for your skin or hair type can increase sebum production. Hair products and skin care products that contain ingredients like mineral oils and silicones can clog pores and prevent sebum from flowing normally.

- Environmental factors :

Environmental factors such as pollution, heat, and humidity can also affect sebum production. For example, pollution can worsen acne and increase sebum production.

Conclusion :

In conclusion, oily hair is caused by excessive production of sebum , an oily substance produced by the sebaceous glands located under the surface of the skin. This excessive production of sebum can be due to genetic factors, stress, poor diet, the use of inappropriate hair products, or environmental factors.
