What is dandruff and what are its symptoms and causes?
Dandruff or pityriasis capitis is a condition of the scalp where the skin starts scaling and flaking. The top layer of the scalp skin is excessively shed and renewed constantly. Where the cycle of shedding is pretty normal, it is a cause of worry when it offloads in uncontrollable volumes. Generally, when the cells are shed one at a time they are seldom noticed. Large clumps of cells are visible on the shoulders or in the hair traps when you have dandruff.
Symptoms and causes of dandruff and itching:
An itchy scalp and flaking are the most predominant symptoms of dandruff. These flakes are oily and white in colour and often tend to aggravate during winter and fall when the air is really dry.
The causes of dandruff are attributed to many factors and pointing towards an exact source is rather difficult:
Understanding seborrhoeic dermatitis:
Seborrhoeic dermatitis is a severe form of a disease that leaves the skin of the scalp feeling itchy and looking red and scaly. Where it sounds a lot like dandruff the difference lies in the inflammation of the scalp and the pronounced scales. One more thing about seborrhoeic dermatitis is that it has a tendency to affect other parts of the body too. It proliferates to the areas of the body where there is a high concentration of oil glands. The body reacts to the yeast in combination with other products administered to the scalp, which further breaks down the oil content secreted by the glands. Other factors that affect seborrhoeic dermatitis are physical and emotional stress, HIV and related illnesses, genetic and seasonal elements.
