Is it normal for newborns to lose hair?

Why This Happens

Hair loss in infants is generally a result of biological transitions. While every baby is different, there are a few common explanations for why this occurs:

• Hormonal shifts: During pregnancy, high levels of hormones keep the hair in a growth phase. After birth, these hormone levels drop significantly, which can push many hair follicles into a resting phase, leading to shedding.
• The natural hair cycle: Newborns undergo a process called telogen effluvium, where a large amount of hair enters the shedding phase simultaneously. This is a natural part of the cycle to make room for permanent hair.
• Physical friction: Frequent rubbing against sheets, car seats, or the mattress—especially at the back of the head where infants spend most of their time—can cause thinning or “bald spots.”

What It Might Mean in Your Situation

When observing your newborn, it is helpful to look at the pattern and timing of the hair loss. If the thinning is happening generally across the scalp or specifically where the baby’s head rests on a surface, it is most likely a normal part of infancy. The timing usually peaks between two and six months, though it can start earlier.

You may notice that your baby’s hair color or texture changes as the birth hair falls out. Some babies are born with a full head of dark hair that falls out, only to grow back blonde or curly. This shift is common and reflects the baby’s developing genetic expression rather than a problem with their health.

What To Do About It

1. Practice gentle grooming: Use a soft-bristled baby brush to gently massage the scalp. This can help remove loose hairs and stimulate blood flow without irritating the skin.
2. Manage bathing habits: Avoid using harsh soaps or scrubbing the scalp vigorously. Use a mild, baby-safe shampoo and gently pat the hair dry with a soft towel instead of rubbing it.
3. Monitor for other symptoms: Keep an eye on the skin beneath the hair loss. If the scalp looks healthy, pink, and smooth, it is likely standard shedding. If you see redness, scaling, or crusting, this is a sign to mention it to a professional.

Real-Life Example

Sarah noticed that her three-month-old son, who was born with a thick mop of brown hair, began developing a noticeable bald patch on the back of his head. Initially, she worried he was losing hair due to a deficiency. However, after noticing that the thinning occurred exactly where his head rested during naps and that the hair on the sides remained thick, she realized it was simply friction-based shedding combined with the natural hormone drop. She continued gentle care, and by the first birthday, his permanent hair had grown in evenly.

When To Seek Outside Help

While newborn hair loss is typically benign, outside help from a pediatrician is useful if the hair loss is accompanied by persistent distress, skin inflammation, or other worrying signs. Please contact a healthcare provider if you notice severe redness, pustules, extreme scaling, or if the baby seems to be in pain when the scalp is touched. Professional guidance can help differentiate between normal shedding and conditions like seborrheic dermatitis (cradle cap) or other skin issues.
