Telogen Effluvium
Sudden stress relate hairs loss which appears as thinning throughout the whole scalp

Telogen Effluvium occurs when sudden or severe stress causes an increase in the shedding of the hair. In Telogen effluvium a sudden or stressful event can cause the hair follicles to prematurely stop growing and enter into a resting phase. The hair will then stay in the resting phase for about 3 months after which time a large amount of hair will be shed. Often the person involved will have recovered from the event before the hair loss occurs. In most cases the hair loss is temporary and the hair soon recovers. However in some cases the hair loss continues until the underlying cause is fixed. Telogen Effluvium appears to affect more women than men because more of the precipitating event such as childbirth are experienced by women.

Temporary hair loss can be caused by:

Child Birth
Pregnancy Terminationís
Starting or Stopping Birth Control Pills
Dieting Drug
Severe Emotional Stress

Many woman notice that their hair is thicker and healthier during pregnancy, this is due to the increased levels of hormones oestrogen and progesterone which cause more hairs than normal to remain in the growth phase. When the child is born however many of the hair follicles that had delayed entering the resting phase suddenly enter the resting phase due to the rapid drop in hormone levels. As a result of this these hairs are then shed about 3 months after the birth.

Hair loss resulting from Pregnancy Terminationís

Similar to the way in which sudden hair loss can occur after childbirth sudden hair loss can also occur after and abortion or miscarriage which the hair loss is triggered by sudden changes in hormone levels. Hair that has remained in the growth phase due to increased hormone levels will suddenly enter the resting phase and will be shed approximately 3 months after the event.

Hair loss resulting form taking the Birth Control Pill

Birth control pills affect the hormone levels within the body and these hormone levels can affect hair growth. In some cases hair thinning may occur due to the male hormones present is some types of contraceptive pills, this type of hair loss is similar to pattern baldness or Androgenetic Alopecia. However discontinuation of The Pill can result in hair loss similar to that which occurs after child birth due to the drop in hormone levels.


The shock involved in a major operation can result in sudden hair loss. Also after micrograft and minigraft surgery where follicles are transplanted on the scalp Telogen Effluvium almost always occurs. Due to the shock of surgery the hair follicles will fall out within about 3 months after which time new hairs will grow from the transplanted follicles.
