Dandruff – What It Is and the Most Effective Ways to Control It

9 May 2024

Seborrheic dermatitis and dandruff are part of the same spectrum of disease affecting the oily areas of the body. Dandruff is limited to the scalp and involves itching, skin flaking, without visible inflammation. Dermatitis can affect the scalp, as well as other oily areas, and involves itching and skin flaking, inflammation, and itching. Various factors such as sebum secretions, fungal colonization on the skin surface, our sensitivity, and the interactions between these factors contribute to the appearance of problems.

As the causes of dandruff are very varied and still being studied, it is important to know some details. At the same time, we will also discuss effective remedies for controlling this problem.

Dandruff – General Information

Seborrheic dermatitis and dandruff are common dermatological problems that affect the oily areas of the body. They are considered to have the same underlying condition, sharing many characteristics and responding to similar treatments. The difference between them is only given by location and severity.

It is estimated that seborrheic dermatitis and dandruff combined affect half of the adult population worldwide. Despite such high prevalence, their etiology is still not fully understood. Genetic, biochemical studies, and animal investigations have provided insight into the pathophysiology and strategies for better treatment.

However, dandruff can be kept under control by introducing adjuvant supplements into the diet, such as Premium Aronia Collagen, a formula created for the health of nails and hair. With a natural origin and a composition based on Hydrolyzed Collagen, Biotin, Hyaluronic Acid, Aloe Vera, and others, it is very effective. Collagen consumption helps maintain hair health, improving the signs of dandruff.

At the same time, the product helps to increase hair strength, elasticity, and structure. Moreover, collagen also helps prevent aging, thus keeping white hairs at bay.

Last but not least, collagen in supplements also enhances skin well-being. Besides becoming shiny, elastic, and resistant, it will no longer be prone to flaking. Consequently, we will no longer suffer from dandruff.

What are the most common causes of dandruff?

Dandruff is very common and affects about 50% of the adult population worldwide. It is also more prevalent in men than in women. Dandruff occurs at puberty, reaches maximum incidence and severity around the age of 20, and becomes less common among people over 50.

Although it is not medically serious, it can affect self-confidence. One in five people suffers from this scalp condition. A mild shampoo can treat milder cases, but symptoms can return over time. Cases also vary depending on the person and skin sensitivity. Understanding the causes that lead to dandruff is a major step in treating it.

What factors can cause dandruff?

Once we have eliminated everything from our routine that could irritate our scalp enough to cause dandruff, we can more easily intervene for improvement. Here are the main causes of dandruff:

1. Irritated or Oily Skin

Most people assume that only people with dry scalps suffer from dandruff. While dry skin can be to blame, it’s not the only cause. An oily scalp results from increased production of sebum, the natural oil on our scalp. This leads to dandruff-producing conditions, such as seborrheic dermatitis, also known as scalp eczema.

If we suffer from seborrheic dermatitis, we can consult a dermatologist for various forms of treatment. The doctor may initially recommend over-the-counter treatments, such as shampoos and natural remedies for dandruff.

If these treatments do not help, the doctor will recommend topical ointments and creams that control inflammation. At the same time, there are also medicinal treatments that help control and alleviate this problem.

2. Shampooing

Some people believe that dandruff worsens the more often they shampoo their hair, but this is not the case. In fact, if we don’t shampoo enough, more oil and dead skin will sit on the scalp, worsening dandruff. A specially designed shampoo can help us.

Shampoos containing ketoconazole, selenium sulfide, or zinc are best for treating dandruff. We can also use a conditioner for dandruff if our hair is more fragile than usual.

3. Malassezia Infection

The main culprit of dandruff is a fungus called Malassezia. This fungus exists on the scalps of most adults. It feeds on scalp oils, breaking them down and leaving behind oleic acid. Many people are sensitive to oleic acid. The body then reacts to this acid by increasing the rate at which skin cells regenerate. It’s an attempt to get rid of the irritant, causing flakes to appear. These are dead skin cells that accumulate visibly on the scalp or even on the shoulders.

This is why a dandruff shampoo and conditioner can be so helpful in treating dandruff. Regular shampoos struggle to clean all the flake buildup. However, more is needed to address the causes of dandruff in men and women. Dermatological shampoos have the right ingredients to do this.

4. Dry Skin

If dry skin is the cause of dandruff, the diagnosis is simple, as other parts of the body are likely dry too. Dry skin surfaces can worsen throughout the year due to temperature, and the same applies to the scalp. Fortunately, all we need to do is moisturize properly.

There are several hair products for dry scalps. A moisturizing hair mask will certainly help. However, it is important to choose products that do not contain irritants.

5. Hair Care Products

Like any other part of our body, the scalp is susceptible to irritation and allergic reactions. If the scalp has a sensitivity to a hair care product, contact dermatitis can occur. This is the skin’s reaction to direct contact with an irritant and in many situations causes dandruff. If we notice that the scalp becomes irritated or sore after using certain products, it might be due to a sensitivity.

It is essential to stop using the product immediately. If we are unsure about which product it is, we can gradually eliminate what we are using to figure it out.

6. Other Skin Conditions

Skin conditions like eczema and psoriasis can also occur on the scalp, causing dandruff. Depending on the severity of these skin conditions, over-the-counter treatments may not control it. We should consult a dermatologist before trying anything new. The wrong products can worsen existing dermatological problems.

Risk Factors That Lead to Dandruff

Now that we have learned some details about the causes and remedies for dandruff, it is important to discuss the risk factors. Almost anyone can get dandruff, but certain factors can make us more susceptible:

Age. Dandruff usually first appears in youth and continues into middle age. This does not mean that older adults do not get dandruff. For some people, the problem can be lifelong.

However, young people entering puberty are most prone to dandruff episodes. The physiological process of growth, the hormones involved, as well as all the chemical reactions in the body, increase the chances of an adolescent developing dandruff. This condition continues to be evident until around the age of 20. As we move into adulthood, our body is no longer stressed by the growth process. Consequently, hormone levels are also no longer the same.

Sex. Dandruff is more common in men than in women. Most likely, this is influenced by the increased secretion of testosterone in men’s bodies. The hormone also contributes to increased sebum and sebaceous secretion, as well as physiological perspiration. Thus, the scalp has the maximum chance of flaking and forming what we know as “dandruff.”
Certain illnesses. Parkinson’s disease and other conditions affecting the nervous system also seem to increase the risk of dandruff. The same applies if we have HIV or a weakened immune system.

Other Factors Associated with Dandruff

In another vein, people with conditions that involve immunosuppression are far more affected by dandruff. Besides HIV, autoimmune conditions and oncological disorders increase the chances of developing this problem.

As we can see, the causes and risk factors for dandruff are very varied and depend on each individual. By paying attention to the signs our body shows us, we will be able to determine the cause of dandruff. Thus, we will also be able to try effective remedies against dandruff.

What Dandruff Remedies Can We Try?

First of all, it is important to use an anti-dandruff shampoo. There are several different types that we can easily find. It is also important to look for products that contain at least one of these ingredients:

salicylic acid;
zinc pyrithione;
ketoconazole;
selenium sulfide;
coal tar.

It is important to use the shampoo for a month to see if the condition improves. We may need to try more than one product to find the right one.

Natural Remedies for Dandruff

In parallel, there are some natural remedies that could help control dandruff. However, it is important to remember that everyone is different. So, a product that works for someone may not be effective for someone else. Before trying any remedy, we must discuss it in detail with a dermatologist. Here are the main natural remedies for dandruff:

Tea tree oil: it has antimicrobial and anti-inflammatory properties, making it effective in treating dandruff. We can add a few drops of tea tree oil to our regular shampoo. Another option is to apply it directly to the scalp, mixing it with a little coconut oil or water.
Apple cider vinegar: it has antibacterial and antifungal properties that help control the fungus causing dandruff. It is recommended to rinse hair with a diluted apple cider vinegar solution after shampooing.
Aloe vera: it is known for its soothing and moisturizing effects on the scalp. Aloe vera gel applied to the scalp can help reduce irritation and dandruff.
Coconut oil: it is another product that helps through its moisturizing and antimicrobial properties. Applying coconut oil to the scalp and gently massaging it before washing helps nourish the scalp and reduce dandruff.
Clay masks: products with green or bentonite clay enhance oil absorption and scalp cleansing, thus reducing the appearance of dandruff.
Balanced diet: a healthy and balanced diet plays an important role in maintaining scalp and skin health. We must ensure we consume enough essential vitamins and minerals for skin health. This especially includes vitamins A, E, zinc, and Omega-3 fatty acids.

Conclusions

Therefore, it is important to be patient and consistent when trying natural remedies for dandruff. Some remedies may require long-term use and may take several weeks before significant improvements are observed. In parallel, we must absolutely stay in touch with a dermatologist, especially in case of adverse reactions.

Dandruff can be an unpleasant problem, but proper treatment and regular care can help control and reduce symptoms.
