What are common signs of a scalp disorder?

Common signs of a scalp disorder frequently include redness, flaking, itching, or unusual hair loss. These symptoms indicate that something may be wrong with the scalp's health. Redness often signals inflammation or irritation, flaking could suggest issues like dandruff or psoriasis, itching can be related to conditions such as dermatitis or allergies, and unusual hair loss may be linked to various scalp or systemic disorders. These signs are pivotal because they prompt further investigation into potential underlying conditions, which can influence treatment and hair care practices.

The other options describe characteristics that signify healthy hair and a healthy scalp, rather than provide indicators of a disorder. Shiny, even-growth hair and natural bounce are traits of well-maintained hair, while thicker density is often associated with good hair health, none of which point towards the presence of scalp issues.
