If you’ve noticed a few fine hairs left in your baby’s crib or seen a slightly thinner patch on their once-full head, you’re not alone. It can be a surprising sight for new parents, but rest assured, this is a very common and normal part of infancy. Just like many other changes in their tiny bodies, hair loss in babies is typically a temporary phase.
Your little one’s body is going through immense adjustments as they adapt to life outside the womb. The hair they are born with, known as lanugo, has a life cycle of its own, and its shedding is often just a sign of healthy development. Let’s look at the reasons behind this fuzzy phenomenon.
The Two Main Reasons for Baby Hair Loss
Most baby hair loss falls into one of two categories. The first is a natural shedding process. Babies are born with hair that is all in the same growth phase. Around three to four months old, this hair enters a resting phase and then falls out, making room for their more mature hair to grow in. The second common cause is friction. If your baby spends a lot of time rubbing their head against their mattress, car seat, or play mat, you might notice a bald spot developing on the back of their head. This is often called friction alopecia
and is completely temporary.
When New Hair Makes Its Appearance
After the initial baby hair falls out, you might be wondering when to expect the new growth. This can vary greatly from one child to another. Some babies sprout a full head of hair within weeks, while for others, it can take until their first birthday or even longer to see substantial growth. The texture and color of this new hair can also be completely different from what they were born with. That surprise blonde fuzz might very well be replaced by dark brown curls!
Caring for Your Baby’s Hair and Scalp
Caring for your baby’s delicate scalp is simple. Use a gentle, baby-specific shampoo and wash their hair just a few times a week to avoid drying out their skin. Be extra gentle when brushing, using a soft-bristled brush designed for infants. If you notice any redness, flaky patches, or areas of complete hair loss, it’s always a good idea to mention it to your pediatrician to rule out any less common causes, like a fungal infection.
In the vast majority of cases, seeing your baby lose their hair is no cause for concern. It’s simply a natural part of their growth journey. Before you know it, you’ll be marveling at the new hair that grows in its place, marking another beautiful stage in your baby’s development.
