What Causes of Dandruff

Who has not ever had dandruff? The odd thing would be to answer no to this question. What causes of dandruff? Dandruff is produced by cell renewal of the scalp, an activity that intensifies in winter, so it is more common to detect white scales between the hair and shoulders at certain times. However, it can become a problem when its appearance is the frequent or abundant amount since beyond the unsightly effect could be indicative of some disease, such as dermatitis.

And dandruff can be much more than an aesthetic problem. But if you want to combat it and show off a clean mane and immaculate shoulders, to get it you can follow the advice that we will offer later. But before describing what causes of dandruff let's see what types of Dandruff you suffer to find the most accurate solution to your particular case.

Types of Dandruff

There are two types of dandruff. On the one hand, there is dry dandruff, which is the most frequent and that is related to the natural process of skin renewal. The scales are thin and white (also gray) and easily detach after brushing or naturally. It is also identified with dry, dull and rough hair.

On the other hand, there is seborrhea dandruff, indicative of dermatitis. It occurs due to hyper seborrhea, that is, an increase in fat production in the scalp. Hair is characterized by being shiny and lubricated. Dandruff comes in the form of thick scales of yellow color and is more adherent, so it is more difficult to remove them than with a simple brushing. In addition, in some cases, this type of dandruff is also associated with alopecia.

There are more accustomed, and others who, however, are surprised a good day to see how small white dots have covered their shoulders and hair. For what is this? Why does this unpleasant phenomenon occur? What causes of dandruff? Among the causes of the appearance of unsightly dandruff we find the following causes of dandruff:

What causes of Dandruff?

The exact causes of dandruff is unknown. Dandruff can be caused by a number of things, including dry skin; sensitivity to hair products; and skin conditions such as psoriasis, seborrhea dermatitis, or eczema. Without spoiling time let’s start main causes of dandruff.

Dry Scalp/Skin:

This is one of the leading causes of dandruff. Often triggered by the under-moisturized or over-dry scalp and may be due to change in weather or washing of hair too frequently. You will notice this when your scalp itches and white crumbs of dry skin fall off whenever you scratch it.

Malassezia (Fungus) Growing On Your Scalp:

This is a live fungus infestation on the scalp causing a rapid increase in skin cell production and shedding as flakes. In treating this, you need to pick the shampoo that contains Zinc Pyrithione as one of its ingredients.

Seborrhea dermatitis:

in most cases, dandruff is an indicator of this pathology, which is characterized by chronic inflammation of the skin, which not only produces scales but also adds a sensation of itching and redness of the affected area.


Some pathology, such as Parkinson, psoriasis or AIDS, have associated episodes of dandruff, and may even present as a reaction of the scalp to certain microorganisms, such as some types of fungi.

Psychological Causes:

When there is no physical trigger, the mood may have a lot to do with the onset of dandruff. Although there are no conclusive clinical studies, the scaling of the skin is related to the hormonal production. Proof of this is that dandruff occurs more intensely, both in men and women, until the age of 30 and is progressively reduced in adult ages. Situations of stress and emotional distress can trigger the onset of dandruff, along with other symptoms, such as hair loss.

You're not shampooing (or rinsing) your hair enough;

Many people say that shampoo can be the causes of dandruff and hair loss. They don't know shampoo has some extra ingredient and oil which help hair to naturally prevent dandruff. For that, you can use the anti dandruff shampoo when you wash your hair and rinse in the shower to reduce dandruff.


although it is not a direct cause of the appearance of dandruff, it does influence in an indirect way, as much in its intensity as in the period of permanence. Diets low in vitamin B or rich in fats and carbohydrates are a critical factor.


The scalp is extremely sensitive to chemical aggressions. While washing the hair daily is not only healthy but also helps prevent dandruff, if it is done with shampoos containing high doses of detergents the opposite effect is achieved. Nor is it advisable to abuse lacquers and hair dyes.

Environmental factors:

very humid climates favor the appearance of certain fungi that can cause dandruff, while the dry environments intensify the natural scaling of the scalp. Pollution, by itself, does not produce dandruff, but it weakens the skin and may lead to external chemical aggression that will favor its appearance.

We described in above about the main causes of dandruff. We try to show you main fact in details. Now we talk about the treatment of dandruff to remove from your head permanently. 

Anti Dandruff Treatment

If dandruff has made an appearance on your lapel do not let it pass and remedy as soon as possible, as there are different options to combat it. Here are two different aspects of anti-dandruff treatments:

For cases of dry dandruff or natural process, it is enough to use a neutral shampoo and apply a soft brushing, although in cases of doubt, the experts recommend going a dermatologist. In this sense, from the Spanish Academy of Dermatology and Venereology, explain that seborrhea dermatitis has symptoms "that may appear in other diseases" such as itching, peeling, redness or oily skin. They said, "For this reason, treatments should not be used without a correct prior diagnosis,"

Among the recommendations provided by this agency is the use of soaps and shampoos recommended by a specialist, as well as restrict the most intense treatments only to the most annoying periods. They also point out the importance of preventing intense sweating and avoiding climatic aggressions with exposures to extreme cold or heat, as well as spending many hours in the sun.

As for the use of shampoos, although they can be bought without prescription in a pharmacy, it is advisable to go to a specialist, since not all anti-dandruff products have the same causes: some are treatments to eliminate microorganisms, others serve to Regulate fat, others are simply neutral for those who do not tolerate chemical compounds, and so on. Your pharmacist or dermatologist will help you choose the right one for you.

Anti-dandruff natural tonics

For less severe cases and for those who want to prevent the appearance of dandruff, there are many natural remedies, which are usually applied on the hair. Here are some of them:

The base for a hair tonic to strengthen the scalp is achieved with an infusion of 50 grams of thyme in half a liter of water for 15 minutes. To the resulting liquid is added 400 milliliters of alcohol of 90 degrees. This mixture is suitable for all types of hair and is applied once a day in the form of a massage.

Another tonic indicated just to remove dry dandruff is prepared by mixing four tablespoons of lemon with four of apple cider vinegar. It is necessary to apply massaging the scalp for ten minutes and then wash the hair with a neutral shampoo. The same can be done with a mixture based on chamomile and rosemary.

For those who prefer cosmetic products, pharmacies can find a wide range. Those with white nettle are particularly indicated, as this plant, in addition to reducing fat production, prevents dandruff, due to its high content of zinc, oleic acid, linoleum and palm tic.

A very similar effect is produced by the birch oil, either directly applying it on the skin over the red areas or through shampoos or creams containing this element, as it works as a blood purifier, in addition Of curing pimples and pimples.

Cataplasms and products enriched with gentian can also be applied for the elimination of dandruff, since, in addition to zinc, it serves to heal wounds and sores and prevents scaling of the skin. It is used, for example, to treat psoriasis.

You can also opt for other products that contain jojoba (natural moisturizer) or licorice (which regulates the production of fat), among its ingredients.



Caring for a balanced diet is also important to keep dandruff away from our hair and shoulders. For those who need to improve their diet for this purpose, in addition to consuming more foods rich in vitamin B (meat, eggs, legumes and whole grains), you should not forget the sulfur. And is that, sulfur is not only a powerful detoxifier of the liver but also, along with zinc, is necessary to take care of the health of the skin. In addition, it is part of the metabolism of vitamin B1, thiamin.

This component is found in pollen-based foods, such as honey, as well as garlic, onion, leek, radish and nuts (dates, nuts, almonds or chestnuts), among others. The fruits that more sulfur contributes to the body are pear, peach, apricot, cherry, strawberry and orange, so do not hesitate to include them in your particular diet against dandruff. There is also water rich in sulfur. Normally it is not commercialized, but there are spas that have sulphurous waters, with a very particular smell, but which are a luxury for health, whether you take advantage of their benefits by taking a relaxing bath or taking their waters.

Another food that you can’t miss in your diet if you want to say goodbye to dandruff or prevent it from appearing is garlic, with antibiotic and antimycotic properties, which thanks to the illicit substance it contains is able to remove bacteria from the scalp. You also have to help the body to create the natural fat layer of the head, so it is advisable to regularly consume sunflower or pumpkin seeds. The skin of the scalp must be regenerated from time to time, so you need to have normal levels of collagen that are formed thanks to vitamin C. This vitamin can be purchased from citrus fruits such as oranges or vegetables such as broccoli or red peppers.

But if you doubt, sugars are the factor that you have to have more controlled to avoid dandruff. These substances have a high acidity that together with their inflammatory properties can promote the appearance of this problem. Insulin, directly related to sugar, can form dandruff so experts recommend reducing the consumption of sugars, simple carbohydrates and saturated and Tran’s fats, as this improves insulin levels and thereby prevent the appearance of dandruff.

In the final word, we say that not only this kind of cause is responsible for the causes of dandruff. Without that, dandruff can be caused by oily hair and scalp, being male, and age. So you have to find out the main cause of dandruff and take care of your hair by taking the right decision with shampoo or natural homemade ingredients.
