Hair Fall After Giving Birth and How to Care for Your Hair

Your hair will come back, with patience and smart care.

Imagine brushing your hair a few weeks after giving birth and finding more strands than usual on the brush and on your pillow. Is this normal? Will your hair return to how it was?

In this article we answer:

  • Why does hair fall after childbirth?
  • When does it start, and when does it stop?
  • When should you see a doctor?
  • What does a gentle care routine look like?
  • And do hair supplements actually help?

Let's explore the science behind postpartum hair fall in five minutes.

1. Why does hair fall after childbirth?

During pregnancy, hormonal changes keep more hair follicles in the growth phase (anagen) for longer. After delivery, hormones drop suddenly and follicles return to the resting phase (telogen) within about 3 to 6 months, causing what is known as postpartum telogen effluvium .

In a study of 116 women, the share of resting-phase hair was higher at the fourth month after delivery than in the last months of pregnancy, and the study concluded that these changes are not exaggerated in most women.

The takeaway: this is a shift in the hair growth cycle after hormones fall, not necessarily a sign of illness.

2. Is it normal, and when does it stop?

Yes, it is very common. In a survey of 331 women, 91.8% reported hair loss after childbirth. These were the averages reported by the women :

  • Start: about 2.9 months after delivery.
  • Peak: about 5.1 months.
  • End: about 8.1 months.

Important: these are averages from self-reported answers. The survey response rate was 21%, and women who were bothered by hair loss may have been more likely to respond. Your own timing may differ.

The takeaway: postpartum hair fall is common, usually starts a few months after birth, and ended after about eight months on average in this study.

3. When should you see a doctor?

Telogen effluvium usually appears two to three months after the trigger, but it can sometimes "unmask" an underlying condition such as traction alopecia (caused by pulling on the hair) or female pattern hair loss, as a case series of three women described .
A comprehensive review notes that downplaying a patient's complaint about hair loss is a common mistake .

See your doctor if:

  • Shedding continues or increases beyond the months the studies describe.
  • Visible gaps or thin patches appear, especially if you wear tight hairstyles.
  • You feel severely exhausted or have other accompanying symptoms.
  • Worry about the shedding affects your mood or your day.

The doctor may look for other causes and order blood tests if needed, since deficiency of some vitamins and minerals may be a modifiable risk factor .

The takeaway: any shedding that goes beyond what is expected, or comes with a clear change in how your hair looks, deserves a doctor's review.

4. A gentle care routine

These are general habits that reduce stress on your hair during this phase. The sources we reviewed did not show that any topical product stops postpartum shedding.

  1. Wash with a gentle shampoo, only as often as you need.
  2. Apply conditioner or a moisturising mask to the lengths and ends, not the scalp.
  3. Detangle gently from the ends up to the roots with a wide-tooth comb.
  4. Avoid tight hairstyles such as a tight ponytail or narrow braids; constant pulling can add stress on the roots .
  5. Limit high heat (flat iron, blow dryer) where you can.
  6. Look after your sleep and food as much as you can; this phase takes patience with yourself.

The takeaway: being gentle protects the hair you have; it does not stop natural shedding.

5. Nutrition and supplements: what does the evidence support?

A scientific review looked at vitamins A, B, C, D and E, iron, selenium and zinc in non-scarring hair loss. It found the evidence large and conflicting, and that deficiency of these nutrients may be a modifiable risk factor. It called for larger trials in people who have both deficiency and hair loss . So the benefit of supplements in people who are not deficient has not been established.

Claim

What the evidence supports

"Any hair vitamin helps everyone"

Evidence is conflicting, and deficiency may be a modifiable risk factor

"Biotin stops hair fall"

No evidence in the sources used here of benefit for people without a deficiency, and it can interfere with some blood tests

"A biotin mask or shampoo brings hair back"

No evidence here for this; topical products are for moisturising and care only

The FDA states that biotin, often found in dietary supplements, can significantly interfere with certain lab tests, and that it has continued to receive reports of falsely low troponin results caused by it. So tell the lab and your doctor about any biotin you take before any test.

While breastfeeding: ask your doctor or pharmacist before taking any supplement during pregnancy or breastfeeding.

The takeaway: start by finding out whether you are deficient, not by buying a ready-made supplement.

6. Common myths about postpartum hair fall

Myth 1: "This shedding means there is a permanent illness."

Not true. It is very common: more than 90% of women reported it in a self-reported survey .

Myth 2: "My hair will stay thin forever."

Not accurate. This is a phase that ended after about 8.1 months on average in the study, but shedding that persists deserves a medical check.

Myth 3: "A biotin supplement or shampoo stops the shedding."

Not accurate. Evidence on hair vitamins is conflicting, and benefit has not been established for people who are not deficient.

Frequently asked questions

When does postpartum hair fall start? On average about 2.9 months after delivery, according to women's own answers, and follicles return to the resting phase within 3 to 6 months.

How long does it last? It ended after about 8.1 months on average, but the length varies from woman to woman.

Do I need a hair supplement? Not necessarily. The evidence is conflicting, and benefit has not been shown for people who are not deficient. Ask your doctor, especially while breastfeeding.

Does biotin affect lab tests? It can interfere with some tests, so tell the lab and your doctor.

Could there be other causes of hair fall? Yes, postpartum shedding can unmask an underlying condition.

Do tight hairstyles matter? Constant pulling can add stress on the roots, and cases have been described where postpartum shedding unmasked traction alopecia.

Is a supplement suitable while pregnant or breastfeeding? Ask your doctor or pharmacist before taking any supplement.

The Avnzor takeaway

Hair fall after childbirth is common and linked to changing hormones and the hair growth cycle, and in the studies it ended within months on average. Being gentle with your hair and seeing your doctor when needed matter more than any quick product.
