Is it normal for newborns to lose their hair?

Why This Happens

Hair loss in infants is generally a physiological process rather than a medical concern. There are several common explanations for why a baby’s hair may thin or fall out in the first few months of life.

• Hormonal shifts: During pregnancy, high levels of hormones stimulate hair growth. After birth, these hormone levels drop significantly, which can trigger a resting phase for the hair follicles, leading to shedding.
• The hair growth cycle: Like adults, babies go through cycles of growth and shedding. In newborns, the first “set” of hair is often replaced by a permanent set of hair with a different texture and color.
• Physical friction: Newborns often spend a lot of time lying on their backs. Constant rubbing against cotton sheets or car seat fabrics can cause hair to wear away in specific spots, such as the back of the head.

What It Might Mean in Your Situation

When observing your baby’s hair loss, it is helpful to look at the overall pattern and timing. In most cases, the shedding is gradual and occurs across the scalp or in a localized patch where the head rests. The nuance lies in the appearance of the scalp and the baby’s general health.

If the hair is thinning evenly or appearing as a bald spot on the back of the head while the skin remains smooth and healthy, it is likely a standard part of infant development. However, the meaning changes if the hair loss is accompanied by other symptoms. For example, if the skin is intensely red, scaly, or contains pustules, it may be something else, such as cradle cap (seborrheic dermatitis), which is also common but handled differently than hormonal shedding.

Consider how your baby is behaving; if they are feeding well and meeting milestones, the hair loss is likely a cosmetic transition. Consistency in the shedding pattern usually suggests a natural cycle rather than an acute reaction.

What To Do About It

1. Practice gentle scalp care: Avoid scrubbing the baby’s head vigorously. Use a soft-bristled baby brush or a gentle cloth during bath time to keep the scalp clean without causing unnecessary friction.
2. Monitor the skin’s condition: Keep a mental or written note of when the shedding started and whether the skin underneath looks normal. If you notice crusting or inflammation, you can mention it to your pediatrician during the next wellness check.
3. Manage expectations for new growth: Be patient with the timing. New hair may take several months to grow in, and the color and texture of the new hair may be completely different from the hair the baby was born with.

Real-Life Example

Sarah noticed that her three-month-old son, who was born with a full head of dark hair, was starting to develop a bald patch on the back of his head and thinning at the temples. Concerned that he was losing his hair permanently, she brought it up at her pediatrician’s visit. The doctor explained that because the baby spent most of his time on his back, the friction combined with natural hormonal shedding was causing the thinning. Sarah felt relieved to know it was a common phase and simply continued using a gentle baby shampoo, and by eight months, her son had a full head of light brown curls.

When To Seek Outside Help

While newborn hair loss is typically normal, outside professional help from a pediatrician is useful if the hair loss is accompanied by severe redness, oozing, or intense itching. You should also seek medical advice if the baby has other systemic symptoms, such as a fever or poor feeding, or if you have concerns about the baby’s overall growth and development. If you are experiencing significant anxiety or distress regarding your baby’s health that interferes with your daily life, a licensed counselor or postpartum support group can provide valuable emotional assistance.
