3. Dryness or Greasiness: While dryness is commonly associated with dandruff, some individuals might experience greasy or oily patches on the scalp, particularly in cases of seborrheic dermatitis.

4. Redness or Irritation: The scalp may appear red or inflamed due to the constant itching and scratching associated with dandruff. This irritation can sometimes lead to a sensitive or tender scalp.

5. Sensitivity to Hair Products: In some instances, dandruff can exacerbate sensitivity to certain hair care products, leading to increased symptoms or discomfort.

6. Secondary Infections: Scratching the scalp excessively due to itching can cause small wounds or breaks in the skin, potentially leading to secondary bacterial or fungal infections.
