Telogen effluvium is very often and complex hair condition which affects all ages. However, it occurs mostly at women. After androgenic alopecia, this is the second most frequent cause of hair loss and reason why patients address doctors.

In normal conditions, approximately 80-90% of hairs are in growth phase (anagen phase), while the rest of hairs are in telogen (passive) phase of growth. At telogen effluvium, large number of hairs simultaneously enters the passive phase of growth and falls out. The disease often affects mid part of the scalp, rarely temporal or occipital part. Patients do not lose the entire hair, but the hair becomes diffusely thin and weak, and the scalp is clearly visible. Typical hair loss is in temporal area in the frontal hair line. Female patients report that their ponytail has lost volume. In more complex cases, telogen effluvium affects eyebrows, pubic and armpit areas. Hair follicles are not permanently damaged, but large amount of hair is in passive phase. Therefore, the sooner patients start therapy, the sooner will the therapy slow hair loss and make hairs return to active phase. There are two forms of the disease: in the first form, hair loss occurs rapidly and majority of hair is lost in the first two months after the occurrence of telogen effluvium (acute form). In the second form, the hair gradually falls out, passive phase is prolonged and hair loss is prolonged to 6-8 months (chronic form), after which the loss is reduced.

Why does telogen effluvium occur?

There are numerous factors which can cause this condition. Typical telogen effluvium occurs after delivery. Namely, estrogen which is intensively excreted during 9 months of pregnancy has positive effect on hair growth and prolongs anagen (active) phase of hair growth. After delivery, estrogen excretion is reduced and the hair enters the passive phase. All the hairs that should have fallen out during nine months suddenly started falling out, leading to telogen effluvium. Majority of women manages to deal with this problem, as their hair regains volume after a few months.

Each diet leads to hair loss. It is important to remember that we lose hair each time we lose weight. Therefore, we need to make a plan of supplements which we will take during the diet in order to help our hair. Additionally, taking some medications can lead to the occurrence of telogen effluvium. Such medications are antidepressants, beta blockers. Hair loss can occur during the vaccination or after surgical procedures. Most frequent cause of telogen effluvium nowadays is definitely stress (acute, chronical and suppressed). Chronic diseases and lack of specific vitamins and minerals may also cause the diseases.

It is important to note that telogen effluvium can be joined with other conditions which lead to hair loss, usually with androgenic alopecia and alopecia areata.
