built 607 days ago
What is Dandruff?Dandruff (... known as seborrheic dermatitis) is the excess shedding of the top layer of the skin on the scalp, eyebrows or along the sides of the nose. This top layer of skin consists of dead cells, which protect the more fragile cells below. It is normal for these to be shed or rubbed off because the body is constantly producing new cells that simply move up to replace older ones. However, in dandruff, larger "scales" are shed at an increased rate.

Dandruff (... called [S]curf and historically termed Pityriasis capitis) is due to the excessive shedding of dead skin cells from the scalp. As it is normal for skin cells to die and flake off, a small amount of flaking is normal and in fact quite common. Some people, however, either chronically or as a result of certain triggers, experience an unusually large amount of flaking, which can also be accompanied by redness and irritation. Most cases of dandruff can be easily treated with specialized shampoos. Dandruff is not an organism like lice; it is just dead skin that accumulates in the scalp. Dandruff is unlikely to be the cause of hair loss.
