[Alopecia in thyroid diseases: characteristic trichograms]. / Alopezie bei Schilddrüsenerkrankungen: Charakteristische Trichogramme.

ABSTRACT

Trichograms from the parietal and occipital area were evaluated in 34 patients with thyroid diseases, which complained about hair loss. The followings findings can be regarded as characteristic for alopecia in thyroid diseases, being not related to the functional state of the thyroid gland increase of dysplastic hairs over 50%, increase of broken hairs over 15% and strenghthening of these findings in the occipital area. Alopecia in thyroid diseases is not caused by changes within the hair cycle but probably by impaired hair quality.
