Why Is My Baby’s Hair Falling Out?

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!

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!
