Telogen Effluvium: During stressful times, the body may react by causing more hairs than normal to enter the resting phase. This is a form of alopecia called telogen effluvium. The body sheds a large amount of hair, which generally will regrow in 9 to 12 months without pharmacologic treatment.
Can you have alopecia and telogen effluvium?
Sudden loss of hair is usually telogen effluvium, but can also be diffuse alopecia areata. In telogen effluvium, once the precipitating cause is removed, the hair will regrow. Hair loss is a common problem that affects up to 50 percent of men and women throughout their lives.
Can telogen effluvium cause androgenetic alopecia?
With telogen effluvium, the “party line” is that shedding does not cause permanent hair loss. However, what we now know is that repeated cycles of shedding speeds up the onset of androgenetic alopecia in patients WHO ARE GENETICALLY PREDISPOSED to develop genetic hair loss.
How can you tell the difference between androgenetic alopecia and telogen effluvium?
True androgenetic alopecia has less density on the top middle and front of the scalp compared to the back of the scalp. … In telogen effluvium, the density is reduced equally all over the scalp.
Does telogen effluvium cause permanent baldness?
It occurs when there’s a change in the number of hair follicles that are growing hair. If this number significantly lowers during the resting (telogen) phase of hair growth, more dormant hair follicles will present. This results in TE hair loss, which typically isn’t permanent.
What does alopecia look like when it first starts?
A common symptom includes small, round patches of hair loss on the scalp, beard area, or other “hairy” parts of the body. Those with alopecia may also notice hair loss and regrowth at the same time, but in different areas of the body. Hair may also only be missing from one side of the scalp and not the other.
How does telogen effluvium unmask androgenetic alopecia?
In women, pattern baldness is often unmasked by telogen effluvium, which occurs 1 to 6 months after a stressor causes a larger portion of the hair to shift from the anagen phase to the telogen phase, leading to an increasing number of hair follicles in the exogen phase.
