How is Seborrheic Dermatitis Caused?
The cause of seborrheic dermatitis is not known to anyone very precisely till yet. The causes may be different for babies and for adults. Seborrheic dermatitis may be related to hormones, because the problem often starts in infancy and goes away before puberty. The most popular theory is that it is caused by a sensitivity to yeast called Pityrosporum ovale on the skin, but it has not been proved yet. It is believed that the build-up of yeast in these glands irritates the skin causing redness and flaking. This organism is normally present on the skin in small numbers, but sometimes its numbers increase, resulting in skin problems.
