After child birth a lot of changes occur to enable the body revert to its nonpregnant state. Hair loss is one of the changes that can negatively impact on the new mom, who is also passing challenges related to child care. 

Hair growth in humans follows through a cycle consisting of a growth phase, regression phase and a resting phase.

On the normal human scalp, only about 10 percent of hairs are in the resting phase at any given time, while about 90 percent are growing and less than 1 percent of the hairs are in regression phase.

About 100-150 hairs on the scalp are shed daily. This normal cycle replaces the hair on the head every 3-5 years. 

what is hair loss after child birth?

Hair loss after child birth medically referred to as postpartum telogen effluvium, is a diffuse nonscarring hair loss which commonly occurs 2-3 months after childbirth. 
It is a normal process and self-limiting over a period of months. The woman may be reassured that her hair growth will return to normal within a few months and that the excess hair lost in the comb or brush will regrow.

During pregnancy the placenta produces significant amount of pregnancy hormones (oestrogen and progesterone). Oestrogen increases the development of hair and causes improvement of hair and skin quality during pregnancy. 

After the removal of the placenta during child birth, the hormones level falls. This causes drop in the pregnancy hormones and this serve as a trigger to the hair loss within months after delivery.

The result is an abnormal shift in hair cycling that leads to the premature shedding of the hair as a result of sudden fall in the pregnancy hormones.

The disorder may have a significant impact on the woman’s mind and would require attention, time, and empathy.

The condition has no predilection for particular race or ethnic group. As a greater percentage of hair begins to undergo the growth phase, more hair falls out with combing and brushing. The loss is in a diffuse, not balding pattern.

The time women loss their hair after child birth is variable and often reaches a peak in the 3rd post-partum month. However, this period may extend up to 6 months in some women.

Excessive hair loss after childbirth must be differentiated from psychogenic hair loss in which the patient seeking advice for hair loss is not necessarily balding. It should also be differentiated from male pattern baldness seen in women with polycystic ovarian syndrome.
