Why Is My Baby’s Hair Falling Out?

Advertisements

When Little Man was born and they handed him to me for his first cuddle, one of the first things that really struck me was his hair. He had a pretty good head of hair for a newborn, but the thing that really surprised me was how wavy it was. I was convinced that when it grew longer he would have a head of lovely corkscrew curls.

For the first couple of months, debate raged about what colour his hair was. Blonde? Ginger? Strawberry blonde? There are several redheads in the family, who were pretty invested in the idea of him joining their number.

And then… The hair on one side of Little Man’s head started disappearing. Then the hair on the other side. And finally the hair on top. It’s now grown back to about it’s original thickness – but it’s much blonder, and straighter. It looks totally different, except for right at the nape of his neck, where there’s a little patch of wavy ginger hair still hanging on. See below for photos!

Little Man’s hair – before and after

So… What the heck happened? Why was my baby’s hair falling out, and why did it grow back different? I love finding out about child and baby development, so I had to get a’Googling!

Why does babies’ hair fall out?

It’s totally normal for babies to lose all the hair they were born with, during the first six months. It’s thought that this is to do with changing hormones inside their body once they’re no longer sharing mum’s pregnancy hormones. In fact, baby’s hairloss may be caused by the same hormonal shift that causes post-partum hairloss for mum.

Baby’s hair falling out can also be affected by sleeping position, from the friction of baby’s head rubbing against mattresses etc. That’s probably why Little Man lost the hair on his right side first – he much prefers to sleep on that side.

How long before baby’s hair grows back?

Baby’s hair will grow back, but when that happens varies from child to child. Some babies have a full new head of hair by six months, while for others it can take until as late as three years old. For some babies, the hair grows back as it’s falling out, so you may not even notice much of a change.

Most experts agree that by the end of the first year, most of baby’s lost hair will have grown back.

Why does my baby’s hair look different now it’s grown back?

I haven’t been able to find the answer to this one! Lots of sites note that baby hair often grows back a different texture/colour/both, but are silent about why this happens. Do you know? Let me know in the comments!

Post-Partum Body Bullshit

Advertisements

After having a baby, you expect to have a tummy and some weight to lose. That much is expected! But there’s so much weird body stuff that lingers after pregnancy that I didn’t really know about. I suppose that other than the weight, possible stretch marks, and any scars from c-sections or episiotomy etc., I assumed everything else would go back to normal. Oh, how wrong I was!

And even though some of it is minor in the grand scheme of things, I think it’s still okay to find it difficult that your body has changed in ways you weren’t expecting. So, I thought I’d write about it…

Post-Partum Body Bullshit: Weird Stuff Your Body Does After Pregnancy

Post-Partum Hairloss

This one is the worst! I have had issues with hair loss for over ten years, thanks to my pituitary issues. For the last four years or so, since my symptoms have mostly been under control with medication, my hair has been growing back slowly, although it’s still a bit patchy in places. But when I was pregnant, my hair improved so much! It got thick and shiny and generally great. In fact it was pretty much the only good thing about being pregnant (other than getting the baby at the end, obviously!)

Hair tends to get thicker during pregnancy, but not because you’re growing more hair – actually, it’s because it’s falling out less. Strange but true. Of course, what that means is that sooner or later, your scalp needs to catch up on all the hair it would normally have lost during those nine months of pregnancy. Enter post-partum hair loss, which normally kicks in about three months after giving birth.

Even though I know it’s totally normal, I’m still finding it a bit stressful to be pulling handfuls of hair out of my hairbrush on a regular basis. It just takes me back to when my own hair loss was really really bad before my tumor was diagnosed, which was a horrible, stressful time.

Annoyingly, my amazing pregnancy lips, which to be fair also looked great and incredibly plump during pregnancy, vanished almost as soon as Little Man was out! Now I’m back to relying on lipstick again…

Moles and Skin Tags

I’ve always had a lot of moles and freckles, but when I got pregnant they went into overdrive! New moles and skin tags appeared everywhere, often seemingly overnight, and they’re still here four months after having had the baby. They particularly seem to have arisen on my chest, back, and belly. Existing moles have also grown, and in some cases turned kind of scaly (ew, sorry).

The development of moles and skin tags in pregnancy is associated with all the oestrogen sloshing around your body. I’ve had my moles checked over by a doctor and she’s said that the changes appear normal and nothing to worry about. But I can’t help but be unimpressed with this new weird bobbly skin.

Weird Tan Lines

So there’s a thing that happens in pregnancy called the linea nigra, a dark line of hyperpigmented skin that runs down your belly. Typically it shows up around the second trimester, caused by pregnancy hormones oestrogen and progesterone, which stimulate the production of melanin in your skin. You may also notice skin darkening on your face and elsewhere as a result of the same process.

When you read about linea nigra online, most sites say it should disappear a few months after delivery. Well, I’m four months out and mine hasn’t faded a bit despite not getting any sunshine. And there doesn’t seem to be much consensus on what to expect, because some other sites say that the line may take a year to fade – or never go away at all.


As well as my linea nigra, I seem to have developed a patch of unpigmented skin on the right hand side of my belly. I’m quite pale so it’s not super noticeable, but it’s big enough that you can see it if you look for it. I haven’t found anything online that suggests that this is a thing which happens with pregnancy, but it definitely wasn’t there before!
