What is Dandruff?
Dandruff is a health condition, where the skin on the scalp turns into dry white flakes, which sheds off from time to time. These flakes are dead skin cells and their shedding is a normal process. When white flakes shed off in large numbers, they start showing off into the hair and on clothing. Dandruff often causes constant itching and may spread all over or may be present in patches on the scalp area. It can be triggered by a variety of reasons like stress, hormonal imbalance, weaker immune system or certain health conditions and medications, which can affect health. In some people dandruff may be triggered after exposure to sunlight.
When dandruff is untreated it expands in leaps and bound and amplifies during winter season and summer months. Usually dandruff can be managed by keeping the hair clean and washing them regularly, however, if required, medical help must be sought.

However growing yeast is the main reason why dandruff increases and these microbes are held directly responsible for varying skin problems. Maximum organisms which are present on skin are not always responsible in increasing dandruff.
Another dandruff condition, called walking dandruff, is usually visible in dogs and other mammals. When dog skin is infected with mites, these mites can be transferred to other animals and humans. This type of dandruff is primarily contagious to animals and also humans. However, this dandruff can be killed and cured with proper medication.
