Hair Changes in Pregnancy
Hair often looks thicker in pregnancy due to hormones — some postpartum shedding a few months later is normal too.

Quick facts
- In pregnancy
- Often thicker, shinier hair
- Extra hair growth
- Face, tummy, arms — common
- Postpartum shedding
- Usually starts ~3 months after birth
- Postpartum shedding ends
- Usually by 6–12 months
- See a doctor if
- Hair loss during pregnancy or patchy bald spots
One of the more pleasant surprises of pregnancy for many people is hair that suddenly looks fuller, thicker and shinier than usual. This happens because pregnancy hormones change your hair's natural growth cycle, meaning fewer strands fall out day to day.
Alongside this, it's also common to notice some extra fine hair growth in places you don't usually have much — the face, tummy or arms. Both changes are harmless and typically settle down again after birth, though the postpartum period brings its own, equally normal, phase of noticeable shedding. This guide covers what's expected at each stage and what would be worth flagging to your doctor.
Why does hair change in pregnancy?
Hair normally grows in cycles: a growing phase (anagen), a resting phase, and a shedding phase, with a steady proportion of your scalp hair shedding at any given time — typically around 50 to 100 hairs a day. Pregnancy hormones, particularly higher oestrogen levels, extend the growing phase and keep more hairs in it for longer, which means fewer hairs than usual enter the shedding phase. The result is hair that appears thicker, fuller and often shinier through pregnancy.
Some people also notice increased fine, downy hair growth on the face (particularly the upper lip and chin), abdomen, arms or lower back. This is caused by the same hormonal shifts and, when mild, is a normal pregnancy change rather than a sign of an underlying condition. It usually fades in the months after birth as hormone levels return to normal.
The 'thickness' isn't extra hair — it's less shedding
Your hair isn't actually growing more strands; more of the hair you already have is simply staying on your head for longer than usual, which is why it feels fuller.
What causes pregnancy hair changes?
Hormonal shifts are behind both the fuller hair many people notice in pregnancy and the shedding that can follow afterwards.
Extended hair growth phase
Higher oestrogen levels prolong the anagen (growing) phase of the hair cycle, so more hairs stay in place rather than shedding.
Increased blood flow and nutrition to hair follicles
Pregnancy increases circulation generally, which some believe contributes to hair looking healthier and shinier.
Mild extra hair growth (hirsutism-like changes)
Hormonal shifts can stimulate fine hair growth on the face, tummy or arms in some people — this is usually temporary and unrelated to any underlying hormonal condition.
Postpartum hormone drop (telogen effluvium)
After birth, oestrogen levels fall rapidly, and all the hairs that were 'held' in the growing phase during pregnancy shift into the shedding phase together, causing a temporary but often alarming-looking increase in hair loss a few months later.
When hair changes are normal
Both the fuller hair of pregnancy and postpartum shedding are expected parts of the hormonal journey. The following are reassuring:
- Hair that feels thicker, fuller or shinier during pregnancy.
- Some fine, soft extra hair growth on the face, tummy or arms.
- Noticeably more shedding starting around 2–4 months after birth.
- Postpartum shedding gradually easing and hair returning to its usual thickness, typically within 6–12 months.
| Usually normal | Needs medical attention | |
|---|---|---|
| During pregnancy | Fuller hair, mild extra fine hair growth | Noticeable hair loss or thinning |
| Postpartum | Diffuse shedding, easing within a year | Patchy bald spots or shedding beyond ~12 months |
| Scalp | Normal scalp, no soreness | Itching, redness, flaking or pain |
Postpartum shedding looks worse than it is
Because so many hairs were 'saved up' during pregnancy, the shedding afterwards can feel dramatic — but it's simply your hair cycle rebalancing, and it does not lead to permanent baldness for the vast majority of people.
Warning signs — when to get hair changes checked
Hair changes are rarely a sign of a medical problem, but see your doctor if you notice:
Seek urgent medical care if you have
- Noticeable hair loss or thinning during pregnancy itself, rather than after birth.
- Patchy bald spots, rather than an even, all-over thinning.
- Hair loss accompanied by a sore, itchy, flaking or red scalp.
- Rapid or excessive new hair growth on the face or body alongside other symptoms such as irregular periods before pregnancy, deepening voice or significant acne (which could suggest a hormonal condition unrelated to normal pregnancy changes).
- Postpartum shedding that is still heavy or worsening beyond about a year.
Reduced or absent baby movements are unrelated to hair changes but always warrant contacting your maternity unit the same day if you notice them.
Caring for your hair through pregnancy and postpartum
Simple, gentle hair care supports healthy-looking hair at every stage.
During pregnancy
- Continue your normal hair-washing routine — pregnancy hormones, not product changes, drive the thickness.
- Use a gentle shampoo and conditioner suited to your hair type.
- If unwanted facial or body hair bothers you, shaving, plucking or trimming are safe options; check with your doctor before chemical hair-removal products or treatments.
During postpartum shedding
- Use a volumising, gentle shampoo and avoid over-brushing wet hair.
- Consider a shorter style or layers if shedding makes hair feel thin — this is cosmetic, not medical, but can help confidence.
- Be patient: shedding typically peaks around 3–4 months postpartum and settles within a year.
General hair and scalp health
- Eat a balanced diet with adequate protein and iron, and continue any antenatal vitamins as advised by your doctor or midwife.
- Avoid tight hairstyles that pull on the scalp if hair feels more fragile.
- Be gentle with heat styling and chemical treatments during and after pregnancy.
No need for special supplements
There's no strong evidence that specific hair-growth supplements speed up regrowth after postpartum shedding. A balanced diet and patience usually do the job — check with your doctor before starting any new supplement.
When to consult a doctor
Speak to your doctor if:
- You notice hair loss or thinning during pregnancy, rather than after birth.
- Hair loss is patchy rather than evenly spread across your scalp.
- Your scalp is itchy, sore, red or flaking alongside hair changes.
- Postpartum shedding hasn't improved by around 12 months.
- You have other symptoms alongside rapid new hair growth (such as irregular periods before pregnancy or a deepening voice) that suggest something beyond typical pregnancy hormone changes.

Noting how your hair changes through pregnancy and postpartum can help you and your doctor tell normal fluctuation from something worth a closer look.
Open the Pregnancy TrackerFrequently asked questions
Why is my hair thicker during pregnancy?
Pregnancy hormones, mainly higher oestrogen, extend your hair's growing phase, so fewer hairs than usual shed each day. Your hair isn't growing extra strands — it's simply holding on to more of what you already have.
Is it normal to grow extra facial or body hair when pregnant?
Yes, mild extra fine hair growth on the face, tummy or arms is a common hormonal change in pregnancy and usually fades again after birth. If it's accompanied by other symptoms suggesting a hormonal imbalance, mention it to your doctor.
Why am I losing so much hair a few months after giving birth?
This is called postpartum telogen effluvium. Falling hormone levels after birth cause the hairs that were 'held' during pregnancy to shed together, usually starting around 2–4 months postpartum. It's normal, temporary, and typically resolves within 6–12 months.
Will postpartum hair loss lead to baldness?
No, for the vast majority of people postpartum shedding is diffuse and temporary, with hair returning to its usual fullness within about a year. If you notice patchy bald spots or shedding continues well beyond a year, see your doctor.
Can I dye or treat my hair while pregnant?
Many people continue their usual hair colouring and styling routines in pregnancy; if you have concerns about specific chemicals, discuss them with your doctor or midwife, particularly for the first trimester if you prefer extra caution.
