▶ Previous Artlcle : #6-1. Various Types of Hair Loss
Representative drugs known to cause telogen effluvium are anti-tumor drugs, and there are various other drugs (Table 1).
In order to determine the causative agent, all drugs taken from 3 to 4 months before the onset of hair loss should be suspected, but it may be difficult to prove unless they are well-known drugs.
If the causative agent is stopped, hair loss will no longer progress after 2-3 months.

Postpartum Telogen Effluvium
Telogen effluvium that comes after childbirth is called postpartum telogen effluvium.
Postpartum telogen effluvium is one of the representative alopecia that occurs in women. It usually begins to appear 2 to 5 months after childbirth, and hair loss occurs mainly in the anterior one third of the head.
The rate of hair loss after childbirth varies from person to person, but it is about 25 to 45%.
When a woman is pregnant, the secretion of female hormone is increased, which leads to a longer anagen phase and a shorter catagen phase during pregnancy, which reduces overall hair loss.
After childbirth, female hormone begins to decrease, and it takes about 3-6 months to normalize.
At this time, the telogen hairs that were waiting without falling out during pregnancy fall out at once, and the number is close to 30% of the total hair.
Six months after childbirth, when the woman finds stability and the hormone balance is restored, the amount of hair loss is normalized and new hair comes back and recovers.
In order to improve nutritional status, it is good to eat foods containing methionine, one of the sulfur amino acids, and avoid stress.
