Pregnancy brings immense change—both beautiful and bewildering. One of the lesser-discussed challenges that many expecting or new mothers face is hair thinning or hair loss. At HDA Clinic in Johannesburg, we’ve seen a growing number of women concerned about the volume and texture of their hair during pregnancy or shortly after giving birth.
The truth is, hormonal fluctuations, nutritional shifts, and physical stress all play a role. While many women experience luscious, fuller hair in the early stages, others notice the opposite—sudden shedding, weakening, and a frustrating lack of regrowth.
This article explores the causes, what to expect at each stage, and what can be done about pregnancy-related hair thinning.
Estrogen is the dominant hormone during pregnancy, and it directly affects the hair growth cycle. Normally, hair grows in a cycle that includes a growing phase (anagen), resting phase (telogen), and shedding phase (exogen).
During pregnancy, the elevated estrogen levels prolong the growth phase. This is why many women find their hair looks thicker and healthier around the second trimester.
However, not everyone experiences this effect. For some, particularly those with underlying deficiencies or hormonal imbalances, hair may actually start thinning during pregnancy. This can be caused by:
In these cases, the hair follicle may enter a premature resting phase, which means less active growth and an overall feeling of hair “going quiet.”
Most women report significant hair loss in the months following childbirth, not during pregnancy itself. This is known as postpartum telogen effluvium, and it’s extremely common.
What Causes It?
After delivery, estrogen levels drop rapidly. The follicles that were kept in the growing phase are suddenly released into the shedding phase all at once. The result? Clumps of hair on your pillow, in the shower, or in your brush.
This typically begins around 8 to 12 weeks after birth and can last several months. For most women, hair begins to normalise by the baby’s first birthday. However, for others, especially those with existing hair thinning, stress, or ongoing nutritional gaps, the loss is more dramatic and recovery is slower.
Signs of Postpartum Hair Loss
If these symptoms persist beyond nine months postpartum, it’s worth having your hair and hormone levels assessed.
Pregnancy-Related Conditions That Worsen Hair Loss
Not all hair thinning during pregnancy is hormonal. Other contributing factors include:
Iron Deficiency Anaemia
Pregnancy significantly increases your iron requirements. When iron levels drop, the body prioritises essential functions—hair growth isn’t one of them. This can trigger thinning or diffuse shedding.
Thyroid Issues
Pregnancy-related thyroid imbalances, such as postpartum thyroiditis, can also lead to noticeable hair loss. These changes often go undiagnosed because symptoms (fatigue, mood changes, dry skin) overlap with normal postpartum recovery.
Polycystic Ovary Syndrome (PCOS)
PCOS often worsens during pregnancy due to insulin resistance and androgen fluctuations. This can contribute to hair thinning, particularly at the crown and sides.
In most cases, yes—but not always at the same thickness or strength. While hair regrowth typically begins within 6 to 12 months, many women notice their hair feels different:
Age, genetics, and nutritional support all influence how effectively the hair bounces back.
During Pregnancy:
Avoid any aggressive hair loss treatments, supplements, or topical applications unless approved by your medical provider.
Postpartum:
Hair loss during or after pregnancy is distressing. It affects self-esteem at a time when many women already feel vulnerable. Acknowledging the emotional toll is crucial.
