Pregnancy may be a key life event where hair loss can develop. Hair loss may begin during the last trimester or it may begin after child birth. Hair loss is often a form of telogen effluvium but sometimes pregnancy can promote the onset of (androgenetic alopecia) in susceptible women.
Post partum alopecia
Postpartum alopecia is quite a common form of hair loss. In non-pregnant women about 10% to 15%of hair follicles are in a telogen resting state. During the late stages of pregnancy more and more hair follicles enter an anagen growth stage until shortly before birth 5% or fewer hair follicles are in telogen. After child birth up to 60% of these anagen stage hair follicles switch off and enter telogen all at the same time. The hair loss may become progressively worse for up to four months after child birth and it may persist for several more months as the hair follicles reorganize themselves and begin activity again.
Pregnancy involves prolonged hormone levels, particularly estrogen. Estrogen is known stimulate hair follicles and maintain them in an anagen growing state. So in pregnancy the hair follicles are not allowed to cycle as they normally would. The hair follicles are forced to keep active even though they might normally want to have a rest as part of the hair cycle. After child birth the estrogen levels suddenly drop and hair follicles are finally allowed to enter telogen all at the same time.
Pregnancy induced effluvium
Pregnant women are eating for two and a growing embryo consumes a lot of energy and nutrients. Deficiencies in certain vitamins and/or minerals can be the result if a diet is not adjusted to increase intake of required nutrients. Telogen effluvium type hair loss may develop.
