Postpartum hair loss, classed as ‘telogen effluvium’, is a fairly common phenomenon that is estimated to affect between 40-50% of women after giving birth. As telogen effluvium-type hair loss typically occurs in response to some systemic shock, such as physical injury, sepsis, childbirth or emotional trauma, it is generally temporary in nature and can be reversed (although the timeframe of this may vary depending on the causes and extent of the trauma).
Hair loss is a complex condition, and environmental factors often play a key role alongside genetic predispositions in triggering loss of hair. Mechanisms of hair loss differ in men and women, but both are believed to involve the hormone dihydrotestosterone (DHT) in later stages. Fluctuations in hormone levels are understood to commonly precede onset of hair loss in both young and menopausal women.
Menopause is a process that marks the end of a woman’s reproductive capacity and is distinguished by cessation of the menstrual cycle. This typically occurs at the average age of 51 years for most women living in the developed world, although onset may occur from anywhere between 40-58 years and may vary according to factors such as ethnicity, smoking status, low parity and/or age of menarche(1,2). Menopause is characterised by changes in hormone levels, most notably oestrogen and progesterone, as well as Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), inhibit A and B, and testosterone, to name a few(3-6).
Hair loss is a complex condition that is not attributable to one single cause. Frequently, hair loss develops as a result of a combination of genetic predispositions as well as environmental factors. In some instances, medical conditions or certain procedures and medications can also have an impact on the expression of hair loss. Current research suggests that whatever the underlying trigger, the final stage in expression of hair loss involves excessive production of the dihydrotestosterone (DHT) hormone(1-4). This is converted by an enzymatic reaction from the precursor hormone testosterone, which is present in both men and women at different levels(1-3).
Alopecia areata is a type of hair loss that causes patches of baldness to appear on the scalp. It is an autoimmune condition that arises when the body’s immune system attacks its own cells, specifically the hair follicles. This interferes with hair growth and causes hair to fall out. Patches of hair loss may range in size from the diameter of a small coin (common in the early stages of the condition) to larger, interconnected areas of hair loss. Alopecia areata may occur in any area of the body in which hair growth naturally occurs, but it is most commonly found to affect hair on the scalp.
In the ancient world, hair was seen as a symbol of status and wealth, and played a significant role in shaping civilization.
