Dermatology - Telogen Effluvium

Dermatology - Telogen Effluvium 
The temporary increased shedding of typical club hairs from dormant scalp follicles is known as telogen effluvium, and it is caused by a rapid transition from the anagen (growth phase) to the catagen and telogen phases (resting phase). This is an adverse response to several physical and psychological stressors, such as medication reactions, heavy metal poisoning, inflammatory scalp disease, physical illness, trauma, acute psychological stress, and changes in hormones and nutrition.

Increased daily hair loss and, in more extreme cases, diffuse scalp hair thinning are present. Most people are nervous and afraid of going bald. There are no scalp anomalies found.
There is noticeable diffuse scalp hair losing, and a mild hair pull collects one to several club or telogen hairs.

A hair pull, clinical signs, history, and potential biopsy are used to make the diagnosis, ruling out other possibilities. The differential comprises lupus, hypothyroidism, hyperthyroidism, diffuse-pattern alopecia areata, loose anagen syndrome, secondary syphilis, and alopecia brought on by medication.
Regrowth in postpartum TE may never be fully achieved if hair loss is significant and recurs after subsequent pregnancies. Up to a year may pass following the precipitating cause of TE.
The rule is complete regrowth of hair, meaning no intervention is necessary.
