What hair condition is indicated by the presence of dandruff?

The presence of dandruff is primarily associated with a dry scalp condition. Dandruff, characterized by flakes of dead skin that can be visible on the hair and shoulders, often occurs when the scalp becomes dry and irritated. This can lead to increased shedding of skin cells, resulting in the noticeable flakes we associate with dandruff.

While an oily scalp may also contribute to flaking due to sebum buildup and potential scalp health issues, the classic presentation of dandruff—especially in its milder form—is linked to dryness. Normal and healthy scalps typically exhibit minimal to no flaking, underlining that dandruff is more indicative of dryness rather than an oily or generally healthy scalp.
