This is a diffuse type of Alopecia.
It is the loss of telogen hair that occurs 2-4mths after an acute systemic stressful episode. The hair matrix is highly susceptible to a variety of endogenous insults. It reverts back to its inactive stage ie telogen.

Normal scalp has 13% of its follicles in telogen. In telogen effluvium, it rises to 20%.
T.E never results in total alopecia (baldness) and is always diffuse. After the radical physiological change comes to an end, the follicles resume their natural growth cycle and produce normal hair.
T.E can occur at any age, but is common between 30 & 50 yrs of age in women.
Some may require CBC & TFTâ€™s in addition to clinical examination.
Classically TE is assessed using hair-pull test.
