Your 4-month-old's hair loss is likely completely normal. Many babies experience hair shedding in the first few months of life. This is often due to a few common reasons:
Common Causes of Hair Loss in 4-Month-Olds
-
Hormonal Changes: After birth, the baby's hormone levels adjust, leading to shedding of the lanugo (fine, downy hair) and the hair they were born with. This is a perfectly natural process. [See references supporting this: BabyCenter, Healthline, Mustela, The Bump, Enfamil, WhatToExpect]
-
Friction: Constant rubbing of the baby's head against surfaces like crib mattresses, playpens, or car seats can cause hair loss. This friction-based hair loss is most common between 3 and 6 months of age, and the hair typically grows back once the baby begins to sit up independently.

-
Sleeping Position: The way your baby sleeps can also contribute to hair loss in certain areas. For example, consistently sleeping on the back of the head can lead to more hair loss in that specific region. [See reference supporting this: Healthline]
When to Seek Professional Advice
While hair loss in 4-month-olds is often benign, consult a pediatrician if:
- The hair loss is patchy or accompanied by other symptoms like skin irritation or rash.
- The hair loss is excessive or seems to be progressing rapidly.
- You have other concerns regarding your baby's health and development.
Addressing Hair Loss
Generally, no treatment is necessary for normal infant hair loss. The hair usually grows back within a few months. However, you can minimize friction-related hair loss by:
- Changing your baby's sleeping position regularly.
- Using softer materials for bedding and clothing that comes into contact with the scalp.
- Ensuring that the baby's head isn't constantly pressed against firm surfaces.
