However, the symptoms of stress have been shown to aggravate a dandruff problem.
There are a whole host of symptoms associated with stress and some can have a knock-on effect which can make dandruff appear worse, including:
Overheating and sweating
These provide the ideal conditions for dandruff-causing Malassezia to thrive.
Hormonal changes
Malassezia globosa breaks down oils (known as sebum) on your scalp, starting the cycle that leads to skin cells flaking off as dandruff.
Sebum production is controlled by hormones so as stress causes changes to your hormonal balance it may cause you to produce more sebum.
This gives the Malassezia globosa on your scalp more oil to break down, so you could see an increase in flaking.
