Dandruff is recognisable by visible flakes that can be seen on the hair and shoulders and can be easily treated with the right shampoo.
How to spot dandruff
Dandruff is caused by a natural microbe on the scalp called Malassezia globosa.
This microbe feeds on your natural scalp oils called sebum.
As the sebum is broken down, it produces oleic acid. 1 in 2 people are sensitive to oleic acid, which the scalp reacts to by becoming irritated and itchy.
Dandruff is recognisable by its key signs, including:
- Itchy scalp
- Irritation or redness
This is the key sign of dandruff. Flakes are caused when the scalp has become irritated and inflamed by the oleic acid.
Your body’s solution to getting rid of the irritant is a signal to the brain to make and shed skin cells at a rapid rate.
Rapid shedding is what causes visible flakes on your scalp and shoulders.
There are other causes of visible white specks in the hair that similar appearance to dandruff:
When the scalp is sunburnt, you may experience redness, itchiness and skin flakes. These are often dry and flaky and can be treated with cooling aloe.
Head lice produce eggs called nits. These are often mistaken for dandruff flakes, as they are a similar colour.
How to tell the difference between dandruff and nits:
- Dandruff flakes are loose; they fall off the hair
- Nits cling to the hair
- Nits have a specific teardrop shape
- Dandruff skin flakes can be found on scalp (where they form) AND hair
- Nits will be found only on hair fibres
Head lice and nits need to be treated with specially medicated shampoos and manual combing.
