You made it through pregnancy with the thickest, shiniest hair of your life. Then, somewhere around month three, it starts coming out in the shower, on your pillow, in your baby's fists. Your brows look patchier. Your lashes feel shorter.
First, the reassuring part: this is common, it has a name, and for most mums it is temporary. Below is what is actually happening, a month-by-month timeline, what helps, and when it is worth seeing a doctor.
Quick answer
Postpartum hair loss (medically, telogen effluvium) usually starts around 2 to 4 months after giving birth, is most noticeable around month 4, and settles between 6 and 12 months postpartum. It is triggered by the drop in oestrogen after delivery. It can affect your scalp, brows and lashes, because they all grow in the same growth-and-rest cycle.
Why it happens
Every hair on your body cycles through three phases: growing (anagen), transitioning (catagen) and resting (telogen), before it falls out and is replaced.
During pregnancy, high oestrogen keeps more hairs in the growing phase for longer. That is why many women notice fuller hair and fewer strands in the drain. After birth, oestrogen drops sharply. All the hairs that were "held" in the growing phase move into the resting phase at roughly the same time, and a few months later they shed together.
So you are not losing more hair than you were going to. You are losing months of delayed shedding in one go. Sleep deprivation, physical recovery from birth and the demands of breastfeeding can make it more noticeable.

Postpartum shedding timeline: month by month
| Time after birth | What you may notice | What to focus on |
|---|---|---|
| 0 to 2 months | Hair still looks full. Little or no extra shedding yet. | Rest, nutrition, gentle hair care. Nothing to "fix" yet. |
| 2 to 4 months | Shedding starts and builds. More hair in the shower and brush. Brows and lashes may thin too. | Handle hair gently. Avoid tight ponytails and heat styling. |
| Around 4 months | Shedding is usually at its most noticeable, often around the hairline and temples. | This is the hardest stretch. It is a phase, not a trend. |
| 4 to 6 months | Shedding slows. Short regrowth ("baby hairs") appears along the hairline. | Support regrowth: scalp care, steady routine. |
| 6 to 12 months | Most mums are close to their usual density, though regrowth takes time to reach length. | Keep going. Length and density catch up gradually. |
| Beyond 12 months | If shedding is still heavy, it is worth checking other causes. | See a doctor (see below). |
Lashes and brows: the part nobody warns you about
Most articles only talk about scalp hair, but lashes and brows follow the same cycle, so many mums notice them thinning in the same months. Lashes are short-cycle hairs, so changes can show up quickly, and so can recovery.
A few habits help while they recover:
- Be gentle when removing eye makeup. Press and hold, don't rub. Tired-eye rubbing during night feeds adds up.
- Give lash extensions a break if your natural lashes are shedding. Extensions add weight to lashes that are already in their resting phase. See Extension Burnout: How to Bring Your Natural Lashes Back to Life.
- Skip over-plucking while brows fill back in. Let regrowth come through before you reshape.
What actually helps
You can't stop postpartum shedding (it is the reset that has to happen), but you can support healthy regrowth and reduce extra breakage.
- Eat for recovery. Protein, iron, zinc and B vitamins all matter for hair. If you are breastfeeding, your nutritional needs are higher. Ask your doctor before starting supplements.
- Be kind to your scalp. Gentle shampoo, no tight hairstyles, minimal heat. In Singapore's humidity, washing frequency matters too: see How Often Should You Wash Your Hair?
- Tell breakage apart from shedding. Shed hairs have a small white bulb at the root. Snapped hairs don't. They need different fixes: Hair Loss or Hair Breakage?
- Build a routine you will actually keep. With a newborn, a one-minute step you do every night beats a 20-minute ritual you do once. Once you've finished breastfeeding, a conditioning serum fits easily into that window. While you're still breastfeeding, we don't recommend using lash, brow or hair serums, so stick to gentle care for now.
- Give it time. Hair grows slowly. Expect weeks to see less breakage and around three months to see visible density. See The 90-Day Hair Density Timeline.
When to see a doctor
Postpartum shedding is normal, but some hair loss after birth has other causes worth ruling out. Speak to your doctor if:
- Heavy shedding continues beyond 12 months after birth
- You notice bald patches rather than overall thinning
- Hair loss comes with fatigue, feeling cold, weight changes or a racing heart, which can point to thyroid changes or low iron, both common after birth
- Your lashes or brows fall out in patches, or your eyes are red, itchy or sore
FAQ
Is postpartum hair loss permanent?
For most women, no. It is temporary shedding that usually settles between 6 and 12 months after birth. If it doesn't, see a doctor to check for other causes.
Can postpartum hormones make my eyelashes fall out?
Yes. Lashes and brows go through the same growth and resting cycle as scalp hair, so the drop in oestrogen after birth can cause them to shed and look thinner for a few months.
Does breastfeeding make postpartum hair loss worse?
Breastfeeding itself doesn't cause the shedding, but it raises your nutritional needs. Not getting enough protein, iron or other nutrients can make hair loss more noticeable.
Can I use a lash, brow or hair serum while breastfeeding?
To be safe, we don't recommend using any of our serums (lash, brow or hair) while breastfeeding. Your hair, lashes and brows usually recover on their own as your hormones settle. In the meantime, focus on gentle care: no rubbing, gentle makeup removal, a break from extensions and no tight hairstyles. You can start a serum routine once you've finished breastfeeding.
Will cutting my hair stop postpartum hair loss?
No. A cut doesn't change what is happening at the follicle. It can make thinner ends look fuller while you wait for regrowth.
