Why Is My Hair Falling Out After Pregnancy? Postpartum Hair Loss Explained

First — you're not going bald.

If you've noticed clumps of hair in the shower drain a few months after having your baby, take a breath. Postpartum hair loss is one of the most common things new mums experience, and in the vast majority of cases, it's completely temporary.

But understanding why it happens makes it a lot less frightening. For a full overview of all hair loss types and causes, read our Complete Guide to Hair Loss in South Africa.

Why does hair fall out after pregnancy?

During pregnancy, elevated oestrogen levels keep your hair in the growth phase for longer than usual. You shed less, your hair feels thicker, and many women notice their best hair of their lives while pregnant.

Then you give birth. Oestrogen drops sharply, and all that hair that was "on hold" suddenly enters the shedding phase at the same time. The medical term is telogen effluvium — and it typically kicks in between 2 and 4 months postpartum.

You're not losing more hair than normal. You're losing the hair you didn't shed during pregnancy, all at once.

When does postpartum hair loss peak?

Most women experience the heaviest shedding around the 3 to 4 month mark after birth. It can feel alarming — especially when you're already sleep-deprived and running on empty.

The good news: for most women, shedding slows significantly by 6 months postpartum, and hair returns to its pre-pregnancy thickness by 12 months. If you're still experiencing significant loss beyond that, it's worth investigating other causes like iron deficiency or thyroid changes — both common after pregnancy.

What makes postpartum hair loss worse?

A few things can intensify or prolong shedding:

• Iron deficiency — very common postpartum, especially if you had significant blood loss during delivery or are breastfeeding
• Poor nutrition — your body is prioritising milk production and recovery; your hair follicles are last in line
• Stress and sleep deprivation — both extend the shedding phase
• Crash dieting — common pressure to "bounce back", but rapid weight loss accelerates hair loss

What can you actually do about it?

Be honest with yourself: you can't stop postpartum hair loss entirely. But you can support your scalp and follicles to minimise the impact and speed up recovery.

1. Get your iron checked
Ask your GP for a full blood count and ferritin test. Low ferritin (stored iron) is one of the most common and most overlooked causes of prolonged postpartum shedding. If your levels are low, supplementing can make a significant difference.

2. Use a gentle, scalp-supportive shampoo
Avoid harsh sulphate-heavy formulas that strip the scalp. Look for shampoos with caffeine, biotin, or zinc — ingredients that support follicle health without irritating a sensitive postpartum scalp.

3. Consider a targeted scalp serum
Once shedding peaks and starts to slow (usually around month 4–5), introducing a hair growth serum can help stimulate regrowth. Look for serums with peptides, rosemary oil, or clinically proven actives like minoxidil if loss is significant.

4. Eat enough protein
Hair is made of keratin — a protein. If you're not eating enough (easy to do when you're exhausted and breastfeeding), your body will deprioritise hair growth. Aim for adequate protein at every meal.

5. Be gentle with your hair
Avoid tight ponytails, excessive heat, and aggressive brushing while your hair is in a fragile state. This won't stop the shedding, but it will reduce unnecessary breakage on top of it.

When should you see a doctor?

See your GP or a trichologist if:

• Shedding hasn't improved by 9–12 months postpartum
• You're noticing bald patches (not just diffuse thinning)
• You have other symptoms like fatigue, weight changes, or feeling cold — these can point to thyroid issues
• Your ferritin or iron levels come back low

Frequently Asked Questions

Is postpartum hair loss normal?

Yes — it affects up to 50% of women after childbirth. It's caused by the hormonal shift after delivery and is almost always temporary.

When does postpartum hair loss stop?

Most women see shedding slow by 6 months postpartum, with full recovery by 12 months. If it continues beyond that, see your doctor to rule out iron deficiency or thyroid issues.

Can I use minoxidil while breastfeeding?

No — minoxidil is not recommended while breastfeeding. Focus on scalp-supportive shampoos, nutrition, and iron levels first. Introduce a serum once you've stopped breastfeeding if needed.

Does postpartum hair loss affect the hairline?

Yes — many women notice thinning or short regrowth hairs around the hairline and temples. This is normal and typically one of the first areas to recover.
