TELOGEN EFFLUVIUM (HAIR SHEDDING)
Other names: acute telogen effluvium, rapid hair fall, TE
What is telogen effluvium?
Telogen effluvium is a general term that means excessive hair shedding. It’s normal to lose 50-100 hairs per day. When this number is exceeded, a clinician may consider the diagnosis of telogen effluvium. Telogen effluvium is not a specific condition but rather a term used to describe over 50 conditions that give excessive daily hair fall.
What are the common causes of telogen effluvium?
A number of conditions can cause telogen effluvium, including:
- low iron levels
- thyroid problems
- crash diets
- medications, including starting and stopping the birth control pill (see larger list)
- major stress
- severe illness
- high fever (infection, etc)
- labour and delivery (post partum telogen effluvium)
How long does shedding last?
Shedding will continue provided the trigger that caused the shedding is still occurring. Once the trigger is removed (for example the iron levels are restored in someone with low iron), the shedding stops in 4-7 months.
Telogen effluvium that goes on many months without obvious cause is referred to as chronic telogen effluvium (see link)
