A smelly scalp is a common issue that can be caused by various factors, including dandruff. While the exact reason for the association between dandruff and a cheese-like odour is unclear, several factors are believed to contribute to this unpleasant scent. One possible explanation is the presence of a type of yeast called Malassezia, which occurs naturally on the scalp. When this yeast proliferates excessively, it can lead to a condition known as dandruff, and the excess yeast may contribute to the cheese-like smell.

What You'll Learn
Yeast overgrowth
A smelly scalp is often accompanied by conditions such as dandruff, seborrheic dermatitis, or scalp psoriasis. In some cases, a smelly scalp may be due to a yeast overgrowth, specifically a type of yeast called Malassezia. This yeast occurs naturally on the scalp, but when it becomes too abundant, it can cause an overgrowth, leading to dandruff and an unpleasant odour.
The symptoms of yeast overgrowth vary depending on the affected area. For instance, candidiasis of the vagina, also known as a yeast infection, may cause redness, itching, and a thick, white discharge. On the other hand, oral thrush, a yeast infection of the mouth, can lead to mouth lesions and digestive issues. If left untreated, yeast overgrowth can enter the bloodstream and spread throughout the body, causing infections in bones and joints.
Treating yeast overgrowth typically involves addressing the underlying cause and restoring the balance of bacteria and yeast in the body. Antifungal medications are often used to treat candidiasis, and the treatment duration depends on the severity of the infection. Additionally, modifying one's diet by reducing the consumption of sugar, refined grains, dairy products, processed meats, and alcohol may help ease the symptoms of yeast overgrowth.
To summarise, yeast overgrowth can be a potential cause of a smelly scalp, and it can lead to various symptoms and health issues. Effective treatment involves identifying the underlying cause, using antifungal medications, and making dietary modifications to restore the balance of bacteria and yeast in the body.

Poor hygiene
To address a smelly scalp caused by poor hygiene, individuals can make simple lifestyle changes, such as improving hair washing habits and choosing suitable hair care products. It is recommended to wash the hair and scalp regularly with a mild shampoo to prevent the build-up of oils, sweat, and grime, which can contribute to odour. "Clarifying" shampoos can be particularly effective in preventing the build-up of hair products and removing excess oils. Additionally, anti-dandruff shampoos containing ingredients like zinc pyrithione, coal tar, or ketoconazole can help inhibit fungal growth and reduce dandruff, improving scalp odour.
It is worth noting that while poor hygiene can be a contributing factor to a smelly scalp, other factors should also be considered. These include underlying health conditions such as fungal infections, hormonal changes, hyperhidrosis (excessive sweating), skin conditions, and diet. Environmental factors, such as pollution and exposure to smoke, can also impact scalp odour.
If individuals find that their scalp odour persists despite improving hygiene practices and trying over-the-counter remedies, it may be necessary to consult a healthcare provider. A persistent smelly scalp could indicate an underlying scalp condition, such as seborrheic dermatitis, psoriasis, or eczema, which may require professional treatment.

Diet
A smelly scalp can be caused by several factors, including yeast overgrowth, fungal infections, poor hygiene, and diet. While the former three factors are well-known causes of dandruff, diet also plays a significant role in maintaining a healthy scalp and preventing dandruff.
Firstly, it is important to understand the link between diet and body odour. Certain foods and spices can directly influence how your scalp and body smell. Common culprits include onions, garlic, and specific spices. The consumption of these foods can lead to pungent sweat, which can worsen scalp odour. Additionally, a diet rich in processed and sugary foods can negatively impact scalp health.
Secondly, dietary deficiencies in certain key vitamins and nutrients can contribute to scalp odour. For example, a lack of specific vitamins and nutrients can lead to skin issues on the scalp, such as dryness and flaking, which are known to exacerbate scalp odour. To maintain a healthy scalp, it is essential to include a balanced diet with nutritious fruits and vegetables.
While treating a smelly scalp caused by diet, it is recommended to keep a food diary. This involves noting down what you eat each day and observing any correlations with a smelly scalp. By systematically working through different foods, you can identify the specific dietary factors that influence your scalp odour.
In conclusion, while factors like yeast overgrowth, fungal infections, and poor hygiene are direct causes of dandruff and its associated odour, diet plays an indirect yet crucial role. Maintaining a balanced and nutritious diet while avoiding certain odour-causing foods can help prevent and treat a smelly scalp, thereby reducing the occurrence of dandruff and its cheesy smell.

Pollution
A smelly scalp can be caused by a variety of factors, including poor hygiene, underlying health conditions, and environmental factors such as pollution. While it is not uncommon for individuals to experience a smelly scalp at some point, the issue can be unpleasant and embarrassing.
Poor hair hygiene, such as not washing the hair enough, is a common cause of a smelly scalp. This allows for the build-up of sweat, oil, and grime, which can be made worse by wearing hats or scarves that trap bacteria and create an unpleasant scent. Additionally, environmental and chemical pollutants can attach to the hair, contributing to a bad smell. This is particularly relevant for individuals living in polluted cities, where the accumulation of pollutants in the hair can lead to a persistent odor.
To address a smelly scalp caused by poor hygiene, simple lifestyle changes can be implemented. This includes improving hair washing habits, such as washing the hair more frequently with a mild shampoo. "Clarifying" shampoos can be particularly effective in reducing the build-up of hair products and pollutants. Additionally, certain hair care products, such as dry shampoo, can contribute to scalp odor, so choosing the right hair care routine is essential.
In some cases, a smelly scalp may be indicative of underlying health conditions. This can include fungal infections, hormonal changes, hyperhidrosis (excessive sweating), or skin conditions like allergic contact dermatitis, psoriasis, seborrheic dermatitis, or eczema. These conditions can affect the scalp's natural balance of bacteria and fungi, leading to infections and contributing to an unpleasant odor.
While pollution itself does not cause dandruff, it can contribute to a smelly scalp, especially when combined with other factors such as poor hygiene or underlying health conditions. The pollutants in the air can attach to the hair, resulting in a persistent bad smell. This is particularly relevant for individuals who smoke or spend time around smokers, as well as those who work around potent-smelling chemicals.
In summary, a smelly scalp can be caused by a combination of poor hygiene, underlying health conditions, and environmental factors such as pollution. To address this issue, individuals can improve their hair hygiene practices, choose appropriate hair care products, and, if necessary, seek medical advice to treat any underlying health conditions that may be contributing to the problem.

Dandruff is a skin condition that causes itching or flaking of the scalp. It is caused by an abundance of a type of yeast called Malassezia, which occurs naturally on the scalp. While not everyone experiences it, dandruff can sometimes be accompanied by an odour.
If you are experiencing a smelly scalp due to dandruff, there are several hair care products available that can help alleviate the issue. These include:
- Medicated shampoos and topical treatments: Over-the-counter anti-dandruff shampoos often contain active ingredients such as zinc pyrithione, coal tar, and ketoconazole, which can inhibit the growth of fungi on the scalp and reduce dandruff.
- Shampoos containing lemongrass oil: Lemongrass oil has been found to be effective in reducing dandruff and may help with unpleasant odours.
- Tea tree oil: Tea tree oil has antimicrobial properties and is often used to treat skin conditions like dandruff and seborrheic dermatitis.
- Apple cider vinegar: Apple cider vinegar is a natural remedy that can help treat fungal infections and dandruff.
- Lemon juice: Lemon juice has antimicrobial qualities that can help reduce smell-generating bacteria on the scalp. However, it can also make your skin more sensitive to sunlight, so use it with caution.
- Baking soda: Baking soda can be dissolved in water and used as a shampoo alternative to remove excess oil and buildup from the scalp.
In addition to these treatments, maintaining good hygiene practices, such as washing your hair regularly and properly, is important to prevent the buildup of sweat, pollutants, and hair products, which can contribute to a smelly scalp.
For more severe cases of dandruff, there are also specialised hair care product lines designed to address flaking, itching, redness, and irritation associated with the condition. One such example is Jupiter®, a line of vegan and cruelty-free products that includes a medicated shampoo, conditioner, and serum to provide ongoing dandruff control while leaving hair soft, shiny, and refreshed.
