Chronic telogen hair shedding secondary to specified cause – http://id.who.int/icd/entity/1585443443

Diffuse telogen hair shedding lasting longer than six months secondary to an identified cause. To be a true cause of chronic diffuse telogen hair loss, the relationship between the trigger and the hair loss must be reversible and reproducible. Firm diagnosis requires exclusion of other known causes of shedding (especially androgenetic alopecia) and reversal of the hair loss following correction of the causative factor. Accepted causes of chronic diffuse telogen hair loss are thyroid disorders (both hyperthyroidism and hypothyroidism), profound iron deficiency, severe zinc deficiency, chronic starvation, retinoid drugs and systemic lupus erythematosus.
