Poor hygiene, such as not washing hair enough, can cause a cheesy smell
Poor hair hygiene can lead to a cheesy smell. This is often due to a buildup of sweat, oils, hair products, and other environmental factors on the scalp.
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 a healthy scalp. However, when there is an overgrowth of certain bacteria or fungi, it can lead to infections and contribute to a smelly scalp. For example, a type of yeast called Malassezia can lead to dandruff and an unpleasant scalp odour when it becomes too abundant. This yeast naturally occurs on the scalp, but improper washing can cause it to build up and lead to an overproduction of oil, resulting in a cheesy smell.
In addition to yeast, other factors can contribute to a cheesy scalp odour. Sweat, for instance, can build up on the scalp and cause an unpleasant smell, especially if you wear hats or scarves that trap heat and moisture. Environmental factors, such as pollution and exposure to potent-smelling chemicals, can also cause your hair and scalp to take on these scents.
If you are experiencing a cheesy scalp odour, it is important to address it through proper hair hygiene practices. This may include washing your hair more frequently, especially if you have oily hair or an active lifestyle that causes you to sweat more. It is also recommended to use clarifying shampoos to reduce product buildup and to ensure that hats and scarves are washed regularly to prevent the transfer of grime to your scalp.
While poor hygiene is a common cause of a cheesy scalp odour, it is important to note that underlying medical conditions, such as scalp psoriasis or fungal infections, may also be contributing factors. If simple lifestyle changes and improved hygiene practices do not improve the odour, it is recommended to consult a healthcare professional for further evaluation and potential treatment options.

A fungal infection like Malassezia can cause an overgrowth of yeast, leading to a cheesy odour
A smelly scalp is often an indicator of improper washing, but it can also be a symptom of an underlying medical condition. A fungal infection, such as Malassezia, is one such condition that can cause an overgrowth of yeast, resulting in a cheesy odour. Malassezia is a type of yeast that occurs naturally on the scalp, but when it becomes too abundant, it can lead to dandruff and an unpleasant smell. This is because the yeast produces excess oils, sweat, and other by-products that can become trapped in the hair and scalp, creating an ideal environment for bacterial growth and a subsequent cheesy odour.
Fungal infections like Malassezia can be treated with medicated shampoos, antifungal medications, and antifungal creams. Doctors may recommend anti-dandruff shampoos containing pyrithione zinc, which has been found to be effective in alleviating the problem. Additionally, tea tree oil, with its antimicrobial properties, can be used to treat the infection and reduce dandruff. Apple cider vinegar is another popular home remedy that can help balance the scalp's pH levels and reduce yeast overgrowth.
To prevent and manage a cheesy odour caused by a fungal infection, it is important to maintain good scalp hygiene. This includes washing the hair and scalp regularly with gentle, balancing shampoo and conditioner to remove excess oils and sweat without stripping the scalp of its natural oils. It is also crucial to pay attention to one's diet, as certain foods can affect the smell of the scalp and body. Limiting the use of hair products with strong scents can also help manage the odour.
In addition to medical treatments and proper hygiene, some lifestyle changes can help improve the smell of the scalp. Limiting the use of headwear, such as hats and scarves, can prevent the trapping of heat, reducing sweat and odour. When headwear is necessary, it is essential to wash it regularly to prevent the build-up of grime and bacteria. Combing the hair from root to tip can also help distribute natural oils and remove any built-up residue.
While a cheesy odour can be embarrassing, it is important to remember that it is a common condition that can often be treated with simple measures. However, if the odour persists despite proper hygiene and home remedies, it is advisable to consult a healthcare provider or dermatologist for further evaluation and treatment. They can help identify any underlying conditions and recommend appropriate medical treatments.

A smelly scalp is typically an indicator of improper washing or poor hygiene. However, a persistent odor may point to a health condition. A healthy scalp has no noticeable smell. If you notice that your scalp has a cheesy scent, it could be due to a variety of reasons. One of the possible reasons is the use of too many hair products, which can cause a build-up of bacteria, resulting in an unpleasant, cheesy smell.

This buildup can trap bacteria, leading to the creation of yeast with an unpleasant scent. The scent is often described as cheesy or similar to sour milk. This is often accompanied by symptoms such as dry and flaky skin, itchiness, redness, and hair loss.
If you suspect that your hair care products are causing the cheesy smell, it is recommended to switch to clarifying" shampoos designed to prevent product buildup. Look for ingredients such as apple cider vinegar or tea tree oil, which are known to be effective in treating smelly scalp issues. You may also want to try eliminating hair products for a while to give your scalp a chance to recover.
In addition to product buildup, other factors that can contribute to a smelly scalp include diet, pollution, sweat, and improper hair washing techniques.

It may be beneficial to consult a dermatologist for advice on suitable hair care products and washing frequency.
