Dandruff is usually seasonal. It is most severe during the winter and mildest during the summer. Dandruff scales usually occur as small, round, white-to-gray patches on top of the head. Scaling can occur anywhere on the scalp, in the hair, on the eyebrows, the beard and can spread to the neck and shoulders. Dandruff is often known as "dry scalp", but people with oily scalps tend to suffer the most. An oily scalp also supports the growth of P. ovale. Since dandruff is a natural process, it can not be eliminated. It can only be managed and controlled
Dandruff can cause either an overly dry scalp with itchy white flakes that may be waxy or greasy or dandruff can manifest as an oily greasy scalp with scales.
Contrary to popular theory, although bacteria may aggravate a dandruff condition, bacteria do not cause the initial problem. Most medical authorities consider dandruff, even the mildest forms, to be a type of scalp or skin related disease. Clinically, one description of dandruff is seborrhea capitos or excessive sebum production of the scalp. Today most skin specialists agree that dandruff is associated with a tiny fungus called Pityrosporum ovale, or P. ovale for short. This fungus lives on our bodies and scalp all the time, usually without causing a problem. Unfortunately, for some people, it can get out of control... leading to dandruff.
Hope this helped! Best wishes!

The cold air that accompanies winter is much denser than the warm air of summer time. Cold air won't hold much moisture, so winter air is always much drier than during the spring, summer, or fall. Dry air won't moisturize skin, and dandruff is primarily the result of a too-dry scalp.

The air in winter is very dry with low humidity. So you know how your skin gets white and flaky when it's dry? It's the same thing w/ your scalp. It gets dry and gets flaky = dandruff.

Because the arid winter weather makes the scalp irritated which in turn makes the hair greasy and more prone to dandruff. This is my layman's explanation, sorry.

well in the winter there is less humidity which makes things dryer. your head is exposed to the cold more frequintly and causes the scalp to dry and in turn causes more dandruff

Dandruff is flaking skin of the scalp.
Dry skin, flakes more. Air is dryer in the winter then in any other season.

Skin is constantly repairing its self, and with the weather changes the skin is doing it quicker, and that is why it is more noticable, the body is in overdrive renewing the skin on the scalp.

Humidity is generally lower in the winter, resulting in drier skin...which can result in more dandruff...

Because of the use of heaters and the dry skin that comes with that.

coldness causes dry skin becuase the sebatious glands within the skin secrete more during warmer temperatures then cold ones.
