A smelly scalp, sometimes called smelly scalp syndrome, is often an indicator of improper washing, but it can also be a symptom of underlying health conditions. People have described the scent as similar to cheese, milk, or sour milk. There are many potential causes of a smelly scalp, ranging from poor hygiene to diet, pollution, fungal growth, and medical conditions such as psoriasis, dermatitis, and hormonal imbalances.

Poor hygiene
Another factor to consider is your diet. Certain foods such as onions, garlic, and spices can affect how your scalp and body smell. Deficiencies in certain vitamins and nutrients can also lead to skin issues on your scalp, such as dryness and flaking, which contribute to scalp odour. Therefore, it is important to include a healthy balance of fruits and vegetables in your diet and eliminate processed and sugary foods.
In addition to diet, pollution and environmental factors can also cause a smelly scalp. If you smoke or spend time around smokers, your hair may take on the scent of smoke. Similarly, if you work with potent-smelling chemicals, your hair may absorb these odours. Wearing hats and scarves can also contribute to scalp odour, as they can trap bacteria and sweat, so it is recommended to limit their use and wash them frequently.

Fungal growth
A smelly scalp is often due to poor hygiene, such as not washing your hair enough, or environmental factors like pollution and smoke. However, a persistent unpleasant odour, similar to cheese, can be indicative of fungal growth.
The scalp is home to a host of bacteria and fungi, known as the scalp microbiome. When these organisms are in balance, they contribute to the healthy functioning of the scalp. However, an imbalance or overgrowth of a certain type of fungus can lead to infections and a smelly scalp. This is often accompanied by conditions such as folliculitis, dandruff, eczema, and seborrheic dermatitis.
To address fungal growth on the scalp, it is recommended to consult a healthcare provider or dermatologist, who can prescribe appropriate treatments. Antifungal medications, medicated shampoos, and antifungal creams are often suggested to address the root cause of the fungal growth. Additionally, maintaining good scalp hygiene is crucial. This includes regularly washing the hair and scalp, using clarifying shampoos to reduce product build-up, and minimising the use of hats and scarves to prevent the accumulation of grime.
In summary, fungal growth on the scalp can lead to an unpleasant odour, similar to cheese. It is important to address this issue through proper medical care and by maintaining good scalp hygiene practices.

Diet
A smelly scalp can be caused by a variety of factors, including diet, poor hygiene, pollution, and underlying medical conditions. While it is not the only cause, diet can play a significant role in scalp odour.
Some common dietary culprits that may contribute to a cheesy scalp smell include:
Onions, Garlic, and Certain Spices: These foods are known to cause body odour, including scalp odour. If you suspect these foods to be the cause, try eliminating them from your diet and observe any changes in scalp odour.
Meat: Research suggests that a diet high in meat may affect how you smell to others, and this may include the scent of your scalp.
Oily, Fried, and Fatty Foods: Consuming excessive oily, fried, or fatty foods may also impact scalp odour.
Dairy and Soy: Some people have linked the consumption of dairy and soy products with a cheesy scalp smell. However, this may vary from person to person.
To determine whether diet is the cause of your cheesy scalp smell, consider keeping a food diary. Note the foods you eat each day and any changes in your scalp odour. Gradually reintroduce different foods to see if the smell returns. This process can help identify specific dietary triggers.
Additionally, maintaining a balanced diet and staying hydrated can support overall health and healthy scalp function.

Hormone changes
Additionally, hormonal imbalances can cause an overproduction of oil from the skin's glands, including those on the scalp. This excess oil can contribute to conditions like seborrheic dermatitis, characterized by an overgrowth of yeast, resulting in dry, yellowish, scaly patches and an unpleasant scalp odor. Hormonal changes can also impact the health of your scalp and hair, potentially leading to conditions like dandruff or eczema, which are associated with a smelly scalp.
If you suspect that hormonal changes are causing your scalp to smell like cheese, it is advisable to consult a medical professional. They can provide guidance on managing the symptoms and recommend appropriate treatments to address the underlying hormonal imbalances. It is important to remember that scalp odor can be influenced by various factors, including diet, hygiene practices, pollution exposure, hair care products, and underlying health conditions.
To address a smelly scalp due to hormonal changes, you may need to adopt a comprehensive approach. This could include improving your hygiene practices by washing your hair regularly with clarifying shampoos, seeking medical advice on managing hormonal imbalances, and incorporating a healthy diet rich in fruits and vegetables while limiting processed and sugary foods. Additionally, incorporating supplements formulated for scalp health, such as those containing turmeric, ashwagandha root, greens, mushrooms, and vitamins A, C, and E, may be beneficial.
In some cases, hormonal changes during pregnancy or menopause may contribute to the overproduction of oil, leading to a smelly scalp. Consulting a dermatologist or healthcare provider can help address the specific causes and provide personalized treatment options to manage both the odor and the underlying hormonal fluctuations effectively.

Underlying health conditions
A smelly scalp is typically a result of poor hygiene or improper hair washing. However, a persistent odour may be indicative of an underlying health condition.
Dandruff
Dandruff is a common scalp condition characterised by the flaking of the scalp skin. It is often accompanied by itching and can be a source of embarrassment for those affected. Dandruff is caused by the overgrowth of a natural yeast called Malassezia, which feeds on the oils and sweat on the scalp, leading to a cheesy odour. While it can often be managed with over-the-counter anti-dandruff shampoos, severe cases may require prescription-strength treatments.
Seborrheic Dermatitis
Seborrheic dermatitis is a skin condition that can affect the scalp, causing dry, yellowish, scaly patches. It is believed to be caused by an overgrowth of the Malassezia yeast, similar to dandruff. This condition can lead to a smelly scalp and may require medical treatment, such as oral antifungal medications, medicated shampoos, or antifungal creams.
Psoriasis
Psoriasis is an autoimmune disorder that can affect the scalp, causing fine scales or thick, crusty plaques to form. It is often hereditary and can result in a smelly scalp. Treatment for scalp psoriasis typically involves the use of medicated shampoos, antifungal medications, and antifungal creams.
Fungal Infections
Fungal infections, such as folliculitis, can develop on the scalp and lead to an unpleasant odour. These infections can cause inflammatory reactions and require medical treatment. Antifungal medications and shampoos are typically used to treat fungal infections of the scalp.
Hormonal Imbalances
Hormonal changes, such as those experienced during menopause, pregnancy, or menstruation, can affect the scalp and lead to changes in body odour. These hormonal fluctuations can cause excessive sweating, known as hyperhidrosis, which can contribute to a smelly scalp.

Firstly, improve your hygiene practices by washing your hair more frequently with a clarifying shampoo to reduce product and bacteria buildup. You can also try detoxifying scalp masks, balancing shampoos, and conditioners to keep your scalp cleansed and odor-free. Additionally, look for products containing ingredients like apple cider vinegar, tea tree oil, or zinc pyrithione, which can help address dandruff and itching. If home remedies are ineffective, consult a doctor or dermatologist, who may recommend medical treatments such as oral antifungal medication or medicated shampoos.
To prevent your scalp from smelling like cheese, you can make some simple lifestyle changes. Limit wearing hats and scarves, and ensure you wash them regularly to prevent grime and bacteria buildup. Include a healthy balance of fruits and vegetables in your diet while reducing processed and sugary foods.
