Hair And Scalp Disorders

Hair and scalp disorders encompass a range of conditions that affect both hair follicles and the scalp skin, leading to symptoms such as hair loss, itching, scaling, and visible scalp abnormalities. Common disorders include androgenetic alopecia (male or female pattern baldness), alopecia areata (patchy hair loss due to autoimmunity), and telogen effluvium (stress-related shedding). Scalp conditions like dandruff (seborrheic dermatitis) and psoriasis present with flaking and inflammation, often causing discomfort and embarrassment. Infections like ringworm (tinea capitis) and folliculitis can produce red, scaly patches or pus-filled lesions, sometimes leading to permanent hair loss if left untreated.

Structural hair shaft disorders, as well as scarring (cicatricial) alopecia, can also result in irreversible hair loss and changes in scalp texture. Diagnosis of hair and scalp disorders relies on medical history, examination, and sometimes laboratory tests, with treatment tailored to the specific cause, including topical medications, antifungal agents, antibiotics, or systemic therapy.
