Is it normal for a newborn to lose hair?

Why This Happens

Hair loss in infants is usually a physiological response to the transition from the womb to the outside world. Several factors may contribute to this process:

• Hormonal shifts: During pregnancy, high levels of hormones from the mother stimulate hair growth. After birth, these levels drop significantly, which can trigger a resting phase for the hair follicles, leading to shedding.
• Natural growth cycles: Every person has a hair growth cycle consisting of growth, transition, and resting phases. Newborns often enter the “telogen” or resting phase shortly after birth, causing hair to fall out.
• External friction: Newborns often spend a lot of time on their backs. Frequent rubbing against sheets or car seats can cause hair to thin in specific areas, such as the back of the head.

What It Might Mean in Your Situation

When observing your baby’s hair, it is helpful to look at the overall pattern and timing. Most newborns begin shedding between two and four months of age, though some may start much earlier. The nuance often lies in where the hair is thinning and how the skin beneath looks.

If the hair loss is diffuse (happening all over) or occurs in a predictable patch on the back of the head where the baby rests, it is often a standard developmental phase. However, the meaning changes if the hair loss is accompanied by other symptoms. For instance, if the scalp appears extremely red, scaly, or contains blisters, it may indicate a skin condition rather than simple shedding. Similarly, if the baby seems unusually lethargic or has other systemic issues, the hair loss might be a secondary symptom of a different concern.

What To Do About It

1. Maintain a gentle routine: Use a soft-bristled baby brush and mild, baby-safe shampoo. Avoid scrubbing the scalp harshly, as the new hair follicles are delicate.
2. Observe and document: Keep a simple note of when you first noticed the thinning and where it is occurring. This information is helpful for providing a clear history during your baby’s regular wellness check-ups.
3. Consult your pediatrician: At the next scheduled visit, mention the hair loss to your provider. If you notice sudden, circular bald spots or an inflamed scalp, you can request an appointment sooner to rule out issues like cradle cap or alopecia areata.

Real-Life Example

Sarah noticed that her three-month-old son, who was born with a thick head of dark hair, suddenly had a thinning patch on the back of his head. She felt concerned that he was losing his hair prematurely. After observing that the area matched where he rested during tummy time and naps, and noting that his skin was healthy and clear, she mentioned it to her pediatrician. The doctor confirmed it was normal shedding combined with friction, and Sarah felt relieved knowing the permanent hair would grow in over the coming year.

When To Seek Outside Help

While newborn hair loss is usually benign, outside professional help from a pediatrician or pediatric dermatologist is recommended if the hair loss is accompanied by severe inflammation, pus, crusting, or if the baby appears ill. If the hair loss is causing you significant emotional distress or anxiety, speaking with a postpartum support group or a licensed counselor can help you navigate the stresses of new parenthood.
