Postpartum hair loss: timeline, reassurance and red flags

A few months after having a baby, many women are alarmed to find hair coming out in handfuls in the shower or on the pillow. If this is happening to you, you are not alone, and in most cases it is temporary. This guide explains what is going on and when to seek help.

Why hair falls out after pregnancy

Each hair follicle cycles between a growing phase and a resting phase, after which the hair is shed ¹. During pregnancy, hormonal changes keep more hairs in the growing phase, so fewer are shed and many women feel their hair is thicker. After birth, hormone levels change and a large number of hairs move into the resting phase together. Around two to four months later, those hairs fall out ^{2 3}.

This is a form of telogen effluvium, a temporary shedding triggered by a change or stress to the body ⁴. It is common and does not mean you are going bald.

What it usually looks like

• Shedding often starts around two to four months after delivery ².
• Hair loss is spread across the scalp, though it may be most noticeable around the hairline and temples.
• You may see more hair in the shower, on your brush or on clothing.
• The scalp itself usually looks normal, without redness, scaling or bald patches.

How long it lasts

For many women, hair returns to its usual fullness by the baby's first birthday ². Short new hairs often appear along the hairline as recovery happens. If you notice that your hair is still thinning well after this time, it is worth seeing a doctor.

When it may be something else

Sometimes postpartum shedding reveals or overlaps with another type of hair loss ⁵. See a doctor if:

• Shedding continues for much longer than a year after delivery
• You notice a widening parting or thinning on the top of the head, which may suggest female pattern hair loss ⁶
• There are round bald patches ⁷
• Your scalp is itchy, red, painful or scaly
• You have other symptoms such as extreme tiredness, feeling cold, weight changes or a racing heartbeat

Thyroid problems can develop after pregnancy and can affect hair ^{8 9}. Iron deficiency is also common, particularly after heavy blood loss at delivery, and can contribute to hair shedding ¹⁰. A doctor can check these with blood tests.

What may help while you wait

There is no treatment that is known to prevent normal postpartum shedding, but these steps may make it easier to manage ²:

• Be gentle. Use a wide-toothed comb, avoid tight ponytails and braids, and limit hot styling tools.
• Consider a shorter cut. Some women find a shorter style makes thinning less noticeable and is easier to manage with a new baby.
• Use a volumising shampoo and a light conditioner. Heavy conditioners can weigh fine hair down.
• Eat regular, balanced meals. Looking after yourself matters, particularly if you are breastfeeding ¹¹.
• Keep taking any supplements your doctor or midwife recommends. Do not start high-dose supplements without advice.

Confinement and hair washing

In traditional confinement practices, some families advise new mothers not to wash their hair for a period. Washing does not cause hair to fall out; the hairs that come out in the shower had already been released from the follicle. Gentle washing keeps the scalp clean and comfortable ¹². Do what feels right for you, and follow any medical advice you are given.

Treatments and breastfeeding

Many hair treatments are not recommended during pregnancy or breastfeeding. For example, topical minoxidil is not recommended while breastfeeding, and finasteride is not used by women who could become pregnant ^{13 14}. Always check with a doctor or pharmacist before using any treatment while breastfeeding.

Looking after your wellbeing

Hair changes can add to the stress of the early months with a new baby. It may help to know this is common and usually temporary. If you are feeling low, anxious or overwhelmed, talk to your doctor, as support is available. For a broader look at causes, read hair loss in women.
