Summary
I. Understanding the Causes of Dandruff
A. The main causes
In general, dandruff is small white residues resulting from the accumulation of dead skin from the scalp.
It is a natural skin cell regeneration process. It is a 4 to 6 week cycle during which scales are generally eliminated from the surface.
Some people are not affected by this phenomenon simply because the cycle is not accelerated in them.
When cell renewal occurs too quickly, dead cells no longer have time to be eliminated and they accumulate, ultimately becoming more numerous and forming a mass.
B. Link with the scalp
The scalp peeling is caused by a natural fungus called Malassezia Globosa.
When it degrades the sebum of your scalp, an acid is secreted and some people tolerate it more easily than others.
In the case of an intolerance, dandruff appears because the scalp shows irritations and enters a protection phase. It therefore accelerates the cycle by 1 to 2 weeks.
C. Oily Dandruff
Oily dandruff is larger, more visible, and tends to stay in the hair. It is more yellowish and is responsible for greater itchiness than dry dandruff.
Causes of oily dandruff
Oily dandruff mainly forms due to excessive sebum production by the sebaceous glands of the scalp. This overproduction can be triggered by various factors such as stress, a diet high in fats and sugars, or hormonal imbalances.
Excess sebum creates an environment conducive to the proliferation of yeasts like Malassezia, which irritate the scalp and accelerate the renewal of skin cells, thus leading to the formation of greasy dandruff.
Furthermore, the use of unsuitable or overly aggressive hair products can also disrupt the balance of the scalp, increasing sebum production and the formation of dandruff.
D. Dry flakes
Dry dandruff is the most common type, appearing in white flakes, and is usually found in a dry scalp. It can be a source of scalp itching.
Causes of dry dandruff
Dry dandruff is often caused by excessive dryness of the scalp.
Several factors can contribute to this condition, including the use of harsh or unsuitable shampoos, which strip the scalp of its natural protective oils.
Environmental conditions such as cold and dry air in winter, or prolonged exposure to air conditioning or heating, can also dry out the scalp.
Moreover, internal factors such as stress, an unbalanced diet low in essential fatty acids, or deficiencies in vitamins and minerals can exacerbate scalp dryness and promote the formation of dry dandruff.
Finally, some people may have a genetic predisposition to a dry scalp, making the occurrence of dry dandruff more likely.
E. Film plaques
Causes of dandruff flakes
"Scaly patches, also known as seborrheic dermatoses, often appear as large visible particles that adhere to the scalp."
These plaques are generally caused by an excessive proliferation of the Malassezia fungus, which feeds on sebum. When the scalp produces too much sebum, it creates a favorable environment for this fungus, leading to irritation and increased flaking.
Other factors such as stress, hormonal imbalances, and certain medical conditions like psoriasis or eczema can also worsen the appearance of dandruff flakes.
Furthermore, the use of aggressive or unsuitable hair products can exacerbate this condition by disrupting the natural balance of the scalp. A holistic approach, including a balanced diet, stress management, and appropriate hair care, is essential for effectively preventing and treating dandruff flakes.
Why do I suddenly have dandruff?
Dandruff can appear suddenly due to various factors such as hormonal changes, an unbalanced diet, or increased exposure to pollution and harsh hair products.
What deficiencies can be the causes of dandruff?
A deficiency in B vitamins, zinc, and omega-3 can also contribute to the appearance of dandruff. A balanced diet is therefore essential for maintaining a healthy scalp.
II. Natural solutions to combat the causes of dandruff
Dandruff is a common hair problem that can be annoying and sometimes embarrassing. Fortunately, there are many solutions to control and reduce it. Here is an overview of the most effective methods to fight against dandruff.
A. Choosing the right anti-dandruff shampoo
The market offers a variety of anti-dandruff shampoos designed to combat seborrheic dermatitis and other causes of dandruff.
These shampoos often contain active ingredients such as zinc pyrithione, selenium sulfide, coal tar, or ketoconazole. It is recommended to use them regularly, according to the instructions, to maintain effectiveness.
Effects of clarifying shampoos
"Clarifying shampoos can dry out the scalp and worsen dandruff. It is therefore better to choose gentle and natural products that respect the balance of the scalp."
B. Resorting to natural remedies for dandruff
Several natural remedies can be effective in treating dandruff: Apple cider vinegar: It helps to balance the pH of the scalp and reduce the growth of yeast and bacteria. Coconut oil: It moisturizes the scalp and fights the fungus responsible for many scalp infections. Lemon juice: Its natural antifungal properties can help manage dandruff.
C. Changes in hair care habits to combat dandruff
The excess of styling products can contribute to the accumulation of dandruff. Using gentler and fewer products can reduce this problem. Additionally, it is advisable to wash your hair regularly, but not excessively, to avoid drying out the scalp.
Signs of hypersensitivity to hair products
Signs of hypersensitivity to hair products include itching, redness, and excessive flaking of the scalp. It is important to choose suitable products and monitor the reactions of the scalp.
D. Balanced diet to prevent dandruff
Diet plays a key role in skin health, including that of the scalp. Ensuring adequate intake of B vitamins, zinc, omega-3, and probiotics can help improve scalp health and reduce dandruff.
Role of diet in the appearance of dandruff
A diet rich in essential nutrients helps maintain a healthy scalp and prevent the appearance of dandruff. Nutritional deficiencies can weaken the scalp and promote their development.
E. Consultation with a dermatologist for treatment
If dandruff persists despite the use of anti-dandruff shampoos and home remedies, it may be helpful to consult a dermatologist. They can prescribe stronger treatments, such as medicated shampoos or topical steroids, and check for other underlying conditions like psoriasis or eczema.
F. Stress Management
Stress can worsen dandruff in some people. Stress reduction techniques such as meditation, regular exercise, and good time management can help reduce symptoms.
Influence of stress on the appearance of dandruff
Stress can disrupt hormonal balance and weaken the immune system, which can promote the appearance of dandruff. Managing stress is therefore crucial for maintaining a healthy scalp.
Although dandruff can be frustrating, there are several strategies to manage it effectively. By combining appropriate care, specific treatments, and consulting a professional if necessary, it is possible to significantly reduce its presence and maintain a healthy scalp.
