Hair loss in itself is both a symptom and a disease. Depending on the cause, it can lead to the following complaints and symptoms:
Alopecia areata
- Sudden appearance of round/oval foci(s) with complete hair loss; preferentially in occipital and temporal areas (occipital and temporal regions); but may also occur in the beard or eyebrows.
- Nail symptoms: mottled/pitting nails may occur as an associated symptom; mottling predominates (up to 66% of cases depending on the severity of the relapse).
Alopecia androgenetica (AGA) in men.
- Geheimratsecken (Grade 1)
- Tonsure at the back of the head (grade 2)
- Hair thinning of the crown/confluence of the areas (grade 3).
- Horseshoe hair band (Grade 4)
- Baldness is sharply defined, hair growth in the hairy area is normal, the skin is not atrophic
Alopecia androgenetica (AGA) in women.
- Clearing of the frontal area [forehead area] (grade 1).
- Clearing of the frontoparietal area [frontal and lateral area] (grade 2).
- Extensive clearing of the frontoparietal area (grade 3).
Alopecia cicatrica (scarring alopecia).
- Scarring areas
- Special form: frontal fibrosing alopecia (FFA, frontal fibrosing alopecia): band-like, symmetrical scarring hair loss leaving behind individual hairs that are not affected by the scarring process. Localization: in the frontotemporal hairline (“in the area of the forehead and temple”) in women; men suffer less frequently from this clinical picture.
