Dandruff is caused when a type of fungus called Malassezia begins to grow on the scalp. However, this can result in scalp damage and can cause some severe dryness. There is a different type of dandruff wherein the scalp begins to produce more oil and as a result, dandruff appears to be more sticky and oily on the hair.
If dandruff and itching are prolonged or if the condition worsens, it might be a good idea to see a doctor. They can understand the core problem that will respond to a particular diagnosis. Numerous over-the-counter products will help handle flaking and itchiness in the case of mild dandruff without a specific cause.
Choose anti-dandruff shampoo which contains zinc pyrithione. This will work as an antibacterial and antifungal agent.
