The exact cause of Dandruff Dermatitis remains unknown. Several causes are incriminated. The most famous are :

A type of yeast called Malassezia, which is present on everyone's skin, but invades in some people.
A high level of androgens
Overproduction of lipids by the skin
Inflammation
Family History of Dandruff Dermatitis
Other factors rather aggravate seborrheic dermatitis:
The stress.
A cold and dry climate.
Oily skin.
Lotions with alcohol high level.
History of other skin lesionsuch as acne, psoriasis and rosacea.

Dry air during the winter months accompanied by a dry and cold climate could aggravate seborrheic dermatitis.
Dermatitis improves during the summer as the UVA and UVB rays of the sun kill living Malassezia on the skin!

Psoriasis and seborrheic dermatitis can look alike, both in the basic lesions and in the affected areas.
Indeed, there is a condition called sebopsoriasis where seborrheic dermatitis and psoriasis overlap.

Seborrheic dermatitis and acne may appear at the same time in the same patient. Indeed, the 2 diseases have the same primum movens which is the overproduction of oils by the skin. Thus, people suffering from acne are more likely to have dandruff.
