Telogen Effluvium: Know why!

Telogen Effluvium

Our hair has 3 different periods, which we can call “the growth cycle”. Anagen, Catagen and Telogen phases. The anagen phase is the phase in which the hair is born and develops; It takes 3 to 5 years. The catagen phase is the period of change and lasts for 2-3 weeks. The telogen phase which is the place for telogen effluvium, is the resting, shedding period and lasts for 3 months; which is the natural cycle.

During the life of an indiviual, hair falls out an average of 20 times and new hair comes in its place. Of course, the growth and shedding phases of each hair occur at different times, and for this reason, the amount of our hair never decreases or there is no thinning in our hair. Normally, only 10% of our hair is in the telogen phase. When there is telogen effluvium, the number of daily hair loss can be up to 750.


Our hair is a part of our body and our hair is inevitably affected by any change in our general health. Sometimes, when an extraordinary event occurs in our health or life – for example, a major distress, stress, illness, high fever, accident, surgery, etc. – this hair growth cycle is interrupted and disrupted. For this reason, more hair than ever before enters the telogen phase. This rate can be up to 35% and sometimes even 50% of the total hair. In other words, while we accept the loss of 100 hairs in a day as normal, 750 or more hair loss is also possible in a day

During this hair count, there may be cases where we count sometimes 3000, sometimes 6000 hairs falling out. Unfortunately, it can be extremely frustrating for the person experiencing this process.

Extreme Hair Loss

This type of intense hair loss usually occurs 3 months after the event that disrupts the above-mentioned cycle (a great distress, stress, illness, high fever, accident, surgery, etc.), and this type of excessive hair loss, because of the effluvium occurs in the telogen phase, which has the name of telogen effluvium.

Detection of Telegon Effluvium is a subject that requires expertise. Just as we cannot call every hair loss genetic hair loss, we cannot call every “extreme” hair loss Telogen Effluvium.

Daily hair loss can be up to 400 strands, but there are new hairs. For this reason, over time, many short hairs of the same length grow.
