It is also known as seborrhea. It is defined as the excessive shedding of dead skin cells. It occurs in parts of the body with high oil (sebum) production. Body areas that are commonly affected include the scalp (most common site), ears, face, chest, and folds of skin, such as the underarms etc.
A small amount of flaking is normal and in fact quite common. Some people, however, experience an unusually large amount of flaking due to rapid turnover of cells. For people with dandruff, skin cells may mature and be shed in 2-7 days, as opposed to around a month in people without dandruff. The result is that dead skin cells are shed in large, oily clumps, which appear as white or grayish patches.
Scalp psoriasis and seborrheic dermatitis of the scalp can be difficult
to differentiate. Both are common conditions that affect the scalp. In
addition, they share similar symptoms, such as itchy, red, scaly skin.
Most often, the scales of psoriasis are thicker and somewhat drier in appearance than are the scales of seborrheic dermatitis. In addition, psoriasis usually affects more than one area of the body. So if you have scalp psoriasis, you may also have mild psoriasis on your elbows, knees, buttocks or fingers.
There is no single test to confirm a diagnosis of psoriasis or seborrheic dermatitis. A diagnosis is usually made with a visual examination of the affected skin.
The most effective way to control dandruff is to keep the affected area
clean; a proper hygiene must be maintained. All shampoos and other
product which are given to control dandruff will give just a temporary
relief but with the help of homoeopathic medicines the tendency and
symptoms both can be treated, that too without adverse effects.
