What causes dandruff?

There are a number of factors that can contribute to the cause of dandruff from dry skin to hair products and certain illnesses or conditions. Dandruff isn’t caused by poor hygiene but can become more noticeable if you do not regularly wash your hair. Let’s take a look at some of the main causes of dandruff.

Malassezia is a family of fungi that is naturally found on the skin surfaces of many humans and is the most common cause of dandruff and seborrhoeic dermatitis. Malassezia is a yeast-like fungus that requires fat to grow and is commonly found in areas that contain sebaceous glands such as the scalp, face and upper part of the body. When the fungus grows it can cause additional skin cell growth, which in turn causes inflammation which creates more sebum secretion. Old skin cells fall off quicker which will be visible as dandruff.

Seborrhoeic dermatitis 
Seborrhoeic dermatitis is a common skin condition that is caused by an overgrowth of yeast on the skin. Seborrhoeic dermatitis can cause your scalp, face and other areas of your body to become itchy, scaly and red and is a cause of more severe dandruff..

Dry skin
Dry skin is a common cause of dandruff, especially in the winter when we are exposed to colder temperatures and central heating. If you have flakes in your hair or on your scalp that are small and do not appear to be oily, or if you have dry skin on other parts of your body then dry skin is the most likely reason you are suffering from dandruff.

Skin conditions
Dandruff can be caused or worsened by certain illnesses such as Parkinson’s disease and skin conditions such as eczema and psoriasis. Eczema causes the skin to become dry, red flaky and itchy. Psoriasis is a condition that causes red, flaky patches of skin and can result in silvery scales. Both conditions can affect the sufferer's scalp and cause dandruff.

Hair products
Sensitivity to hair products such as hair dye, mousse, gel and hairspray can cause allergic reactions or contact dermatitis. Ingredients within these hair products can irritate the skin and damage the outer layer of skin that causes the scalp to become dry and flaky and result in dandruff.

Seasonal changes
Changes in the weather temperature and our environment such as more exposure to central heating can cause the skin cells on our scalps to dry out and lead to a flare-up of dandruff.
