Possible Causes of Hair Loss and Itching

Conditions that commonly cause both symptoms together

1Early Alopecia Areata often produces non-specific symptoms: fatigue, malaise, or mild discomfort
2Early warning signs may include: hair loss, hair thinning, itching, nail changes
3Subclinical changes in blood tests, blood pressure, or weight often precede overt symptoms
4Family history and risk factors increase the probability that vague symptoms represent early Alopecia Areata
5Screening programmes are designed specifically to detect Alopecia Areata before symptoms appear
6Core management targets: reducing hair loss, hair thinning, itching and preventing disease progression

Conditions That Cause Both Hair Loss and Itching

2 conditions are associated with this symptom combination

Alopecia Areata

Alopecia areata is an autoimmune condition causing patchy hair loss when the immune system attacks hair follicles. It can progress to total scalp (alopecia totalis) or body hair loss (alopecia universalis); intralesional corticosteroids and JAK inhibitors are effective.

Seborrheic Dermatitis

Seborrheic dermatitis is a chronic inflammatory skin condition causing scaly patches and red skin, particularly on the scalp (dandruff), face, and chest. Malassezia yeast overgrowth plays a role; antifungal shampoos and mild topical steroids are effective.
