Malassezia Furfur (aka as Tinea Versicolor) is related to Seborrheic Dermatitis because the yeast feeds off the fatty acids on the skin and the dead cells, so buffing the skin after showering or bathing is very recommended.

The "real" cause is unknown, so I wouldn't be surprised it is related to candida.

There's also a relation between vitamin A and the renewal of surface cells (skin, intestines etc.) so I believe there might be a link there. Vitamin A is important for mucus membranes in general and to prevent infections.

This type of infection [malassezia furfur] is normally associated with dermal-type manifestations. There are topical creams and shampoo's for scalp. It also belongs to the fungi that is commensual to the human host. This may be out-of-control from secondary factors in a pathogenic candida{or other} fungal infection.
It is always recommended to modify diet and start standard anti-fungal protocols. In the case of malassezia furfur, the avoidance of short-chain fatty acids is recommended. Shroom
