Dandruff can be either oily or dry, depending on the cause and appearance of the flakes. Oily dandruff, also known as seborrheic dermatitis, is characterized by larger, yellowish flakes that stick to the scalp and hair and have a greasy appearance. This type is often associated with an overgrowth of the Malassezia yeast, which thrives in oily environments. On the other hand, dry dandruff appears as smaller, white flakes that are loose and easily fall from the hair. This type is usually caused by dry scalp, which may be due to factors like cold weather, infrequent shampooing, or certain hair products.
Here's a quick breakdown of the key differences:
- Oily Dandruff:
