Dandruff is a skin condition that affects the scalp, causing itching or flaking. In some cases, it can be accompanied by an odour, which can range from a mild scent to a strong, unbearable smell. The causes of a smelly scalp can vary from poor hygiene, fungal infections, hormonal changes, or even the natural occurrence of microbes like yeast and bacteria on the scalp. While home remedies such as lemon juice, tea tree oil, and apple cider vinegar can help, persistent or severe cases may require medical attention and treatment with medicated shampoos or antifungal medications.

Poor hygiene, such as not washing hair enough, can cause a smelly scalp
Poor hair hygiene, such as not washing the hair enough, is a common cause of a smelly scalp. The scalp naturally contains microbes, such as bacteria and yeast, which break down the scalp's sebum (natural oils) and dead skin cells. When hair is not washed frequently, these microbes build up, releasing acids and compounds with foul smells. This build-up of sweat, oil, and grime can be exacerbated by hats and scarves, which can trap bacteria and create an unpleasant scent. Environmental and chemical pollutants can also attach to hair, creating a bad smell.
In addition to poor hygiene, a smelly scalp can be caused by underlying health conditions, such as fungal infections, hormonal changes, hyperhidrosis (excessive sweating), or skin conditions like allergic contact dermatitis, psoriasis, seborrheic dermatitis, and eczema. Certain foods, hair products, and medications can also contribute to scalp odour.
To address a smelly scalp caused by poor hygiene, simple lifestyle changes can be made, such as improving hair washing habits and choosing the right hair care products. It is recommended to wash hair frequently with a mild shampoo, especially if living in a polluted city, to prevent the build-up of sweat, oil, and grime. "Clarifying" shampoos can be used to prevent the build-up of hair products, and anti-dandruff shampoos containing ingredients like zinc pyrithione, coal tar, or ketoconazole can help inhibit fungal growth and reduce dandruff.
If home treatments are ineffective, it is important to consult a healthcare provider or dermatologist for guidance. They may recommend medicated shampoos, antifungal medications or creams, or other treatments to address the underlying cause of the smelly scalp.

Dandruff is caused by a build-up of dead skin cells, which can lead to bacteria and an odour
A smelly scalp can be an embarrassing and unpleasant experience for anyone. The scalp naturally contains microbes like bacteria and yeast, which break down the scalp's natural oils and dead skin cells. When we don't wash our hair often enough, these microbes tend to build up, releasing acids and compounds with foul smells. Dandruff is a skin condition that causes itching or flaking, and in some people, it may be accompanied by an odour.
To address a smelly scalp caused by dandruff, it is important to maintain good hair hygiene by washing your hair regularly with mild shampoo. Anti-dandruff shampoos containing ingredients like zinc pyrithione, coal tar, or ketoconazole can help inhibit fungal growth and reduce dandruff. Tea tree oil, with its antimicrobial properties, is another effective remedy for treating dandruff and improving scalp health.
In more severe cases of dandruff, it is recommended to consult a healthcare provider or dermatologist. They may suggest medicated shampoos, antifungal creams, or oral medications to address the underlying cause of the condition. Additionally, maintaining a healthy scalp pH and oil balance is crucial to preventing and treating dandruff.
By understanding the causes and seeking appropriate treatments, individuals can effectively manage and eliminate the odour associated with dandruff.

A type of yeast called Malassezia occurs naturally on the scalp, but an overgrowth can cause dandruff and a cheesy smell
A smelly scalp is an unpleasant and often embarrassing issue that affects many people. The scalp can emit a range of odours, from cheese to mildew, and sulphur. In some cases, the scalp may even smell like sour milk. This is often due to an overgrowth of yeast called Malassezia, which occurs naturally on the scalp. However, when it becomes too abundant, it can cause an unpleasant odour, as well as dandruff.
Dandruff is a skin condition characterised by itching or flaking. It is caused by the build-up of dead skin cells, which fall off as white flakes. This build-up of skin cells can also contribute to the cheesy odour, as it provides an ideal environment for bacteria to grow, further exacerbating the smell.
To combat this issue, it is important to maintain good scalp hygiene. This includes washing the hair and scalp regularly with mild shampoo to prevent the build-up of oils, sweat, and grime, which can all contribute to odour. Additionally, clarifying shampoos can be used to prevent the build-up of hair products, which can also trap bacteria and create an unpleasant scent.
In more severe cases, or if home remedies are ineffective, it is recommended to consult a doctor or dermatologist. They may suggest medicated shampoos, antifungal creams, or oral medications to address the root cause of the issue, such as antifungal treatments for fungal infections or hormonal disorders.
It is important to note that a smelly scalp can also be a symptom of underlying health conditions, such as scalp psoriasis, seborrheic dermatitis, or metabolic and hormonal disorders. Therefore, seeking professional advice is crucial to ensure effective treatment.

Hormonal changes can cause an overproduction of oil from the skin's glands, including those on the scalp
A smelly scalp is a common condition that can be caused by various factors, including dandruff. While the exact reason why dandruff may smell like cheese is unclear, several factors could 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 becomes too abundant, it can lead to a condition known as dandruff, and the excess yeast may contribute to the cheese-like odour.
Hormonal changes can significantly impact the oil production of the skin's glands, including those on the scalp. Androgens, such as testosterone, are produced by the adrenal glands, ovaries, or testes, and they play a crucial role in regulating sebum production. During puberty, sebum production can increase by up to 500%, leading to oily, acne-prone skin. This increase in sebum production is more pronounced in male adolescents, but it affects both males and females.
Additionally, hormonal fluctuations during menopause, pregnancy, or menstruation can also influence sebum production. For example, females tend to produce more sebum in the week before their menstrual period when progesterone levels are higher. While the role of progesterone in sebum production is not entirely clear, it appears to reduce the activity of the enzyme 5-reductase, which is involved in converting less active androgens into more active forms like testosterone. This reduction in enzyme activity could be expected to decrease sebum production.
Furthermore, certain medications and underlying health conditions can impact the activity of the sebaceous glands, leading to increased sebum production. For instance, hormonal medications, including testosterone, some progesterones, and phenothiazine, can increase sebum secretion. Additionally, pituitary, adrenal, ovarian, and testicular conditions can affect sebum production, causing either an increase or decrease depending on the specific condition.
Excessive sebum production can lead to oily skin and hair, contributing to a greasy scalp and potentially exacerbating the cheese-like odour associated with dandruff. While hormonal changes are a significant factor, they interact with other factors, such as diet, hygiene, pollution, and hair care products, to influence the overall scent of the scalp.

Underlying skin conditions, such as psoriasis, can cause a smelly scalp
A smelly scalp is a common concern that may result from poor hygiene or an underlying medical issue. Underlying skin conditions, such as psoriasis, can cause a smelly scalp. Psoriasis is an autoimmune disorder that runs in families. If you have scalp psoriasis, you may have fine scales covering your scalp, or you may have a series of thick, crusty plaques.
There are several treatments for scalp psoriasis. Calcipotriene, a vitamin D-related medication, is used to treat scalp psoriasis by regulating the production and growth of skin cells. Coal tar is another treatment option, but it can make the scalp prone to sunburn. If you are experiencing other symptoms, such as a rash, bleeding, or red patches on the scalp, talk to your healthcare professional, who can help identify the problem.
If you have an underlying medical condition like scalp psoriasis, you might benefit from medicated shampoos and topical treatments. These can help heal the skin conditions on your scalp, which can lead to less odor. For example, medicated shampoos containing clobetasol propionate and salicylic acid are among the active ingredients in many psoriasis shampoos.
In addition to medicated shampoos and topical treatments, there are several home remedies that can help treat a smelly scalp caused by underlying skin conditions such as psoriasis. Lemon juice, for example, has antimicrobial qualities that can reduce smell-generating bacteria on the scalp. However, like many fruit acids, lemon juice can irritate the skin and make it more sensitive to sunlight, so use it with caution. Tea tree oil is another natural remedy with antimicrobial properties that can be effective at treating conditions that cause a smelly scalp.
