Newborns come with many surprises, including their hair, which can be thick, thin, or even completely absent at birth. However, parents often notice that a newborn’s hair may start to fall out within a few weeks after birth, which can be concerning. This hair loss is a natural part of development and is usually temporary. In this guide, we’ll explore why newborns lose their hair, when it typically falls out and regrows, and how you can care for your baby’s scalp during this phase.
Why Do Newborns Lose Their Hair?
The Natural Hair Cycle
Hair grows in cycles, moving through growth, transition, and resting phases. For many newborns, there is a phase called “telogen effluvium,” where hair enters the resting phase and falls out, usually due to a shift in the hair growth cycle. As your baby’s hair goes through this process, some shedding is normal as new hair growth begins. This cycle, while unexpected, is simply a natural reset for hair follicles as they prepare for new growth.
Hormonal Changes After Birth
Newborn hair loss is often influenced by hormonal changes that occur shortly after birth. During pregnancy, a mother’s hormones help the baby’s hair grow. After birth, these hormones drop, which can lead to hair loss, similar to postpartum hair loss that many mothers experience. As a result, the baby’s hair naturally sheds as it adjusts to lower hormone levels, allowing for new hair growth to follow.
Pressure and Friction
Newborns spend much of their time lying on their backs, which can create friction between the back of their head and the crib or bassinet. This pressure can lead to hair thinning or bald spots, particularly on the back of the head. Over time, as babies start to move around and sit up more, this friction-related hair loss often decreases, and hair begins to regrow evenly.
Changes in Sleep Position
Newborns spend much of their time lying down, and this can contribute to hair loss in specific areas. Frequent contact between the back or sides of the head and a crib or mattress can lead to friction-related hair shedding. As babies become more mobile, this type of hair loss often decreases.
Genetic Factors
Genetics play a role in the timing and extent of newborn hair loss. Some babies are more predisposed to early hair shedding or slower regrowth based on their family history. While hair loss varies widely among newborns, genetic factors largely determine how quickly new hair will grow back.
When Does Newborn Hair Typically Fall Out?
First Few Months
For most newborns, hair shedding begins around 8-12 weeks of age. However, this timeframe can vary, with some babies experiencing hair loss earlier or later. While this shedding can be surprising, it’s usually no cause for concern. This initial hair loss is temporary and part of the baby’s hair growth cycle.
Signs of New Hair Growth
While your baby’s hair might be falling out, you may start to notice new hair coming in as early as 3 months. This new hair growth may continue steadily over the next few months. It’s common for this new hair to be different in texture, thickness, or color from their initial hair. By 3-7 months, most babies have a noticeable amount of new hair growth, which continues to fill in and thicken as they grow.
Variations Among Babies
Hair loss timing can vary significantly from one baby to another. While some newborns may start losing hair as early as a few weeks, others may retain most of their hair until they are several months old. Each baby’s hair cycle is unique, and timing often differs based on individual factors.
Differences Between Full-Term and Premature Babies
Premature babies may experience hair loss and regrowth differently than full-term babies. They may retain their initial hair, called lanugo, for a longer period before it begins to shed. Full-term babies, on the other hand, typically shed hair earlier as part of a natural transition to mature hair growth.
Newborn Hair Regrowth
Different Hair Types and Textures
It’s normal for your baby’s new hair to differ from the hair they were born with. Genetics play a significant role in the texture, thickness, and color of the regrown hair. For instance, a baby born with fine, straight hair might develop curly or thicker hair over time. This process reflects their genetic makeup and can vary greatly from one baby to another.
The Timing of Regrowth
Most babies start to show significant hair regrowth between 6-12 months of age. While some babies’ hair grows rapidly, others may have a slower regrowth phase, which is entirely normal. By their first birthday, many babies have developed a fuller head of hair, though each child’s hair growth rate is unique. With patience and time, most children experience steady growth as their hair becomes more defined in color and texture.
How to Care for a Newborn’s Hair and Scalp During This Phase
Gentle Hair Care Practices
Using a mild, tear-free baby shampoo is best for a newborn’s hair. Washing 1-2 times a week is usually enough to keep the scalp clean without drying it out. Since newborns have sensitive skin, over-washing can strip natural oils, which are important for scalp health. Keep washing sessions gentle to avoid irritating their scalp.
Using a Soft Brush
A soft-bristled baby brush is a wonderful tool for newborn hair care. Gently brushing your baby’s hair and scalp can help remove any loose flakes and stimulate blood flow to the scalp, promoting a healthy environment for new hair growth. A soft brush is also gentle on sensitive areas, making it ideal for maintaining scalp cleanliness.
Protecting the Scalp from Friction
Placing a soft, breathable cloth or blanket under your baby’s head during sleep or playtime can reduce friction. Repositioning your baby’s head periodically can also help prevent hair loss and flat spots from developing on one side. As your baby grows, they’ll start to move more independently, reducing the need for repositioning.
Avoid Tight Hats or Headbands
Avoid using tight hats, headbands, or any accessories that could create pressure or friction on your baby’s scalp. These can contribute to hair breakage and discomfort. Opt for soft, loose-fitting hats made from breathable materials to protect the scalp without restricting hair growth.
Monitor for Scalp Conditions
Keep an eye out for any signs of scalp dryness, redness, or flakes, as these can indicate conditions like cradle cap or skin irritation. If you notice persistent dryness or patches, consult your pediatrician for appropriate treatments to keep your baby’s scalp healthy during this hair growth phase.
Moisturizing and Preventing Dryness
If your baby’s scalp appears dry or flaky, a gentle baby-safe oil or moisturizer can provide relief. Lightly apply the oil to the scalp after a bath, and avoid using too much, as this can make the scalp greasy. Proper hydration keeps the skin and hair follicles healthy, encouraging hair regrowth.
Frequently Asked Questions (FAQs)
When does newborn hair fall out and grow back?
Newborn hair typically begins to fall out around 8-12 weeks of age due to natural hormonal changes. New hair often starts to grow back by 3-7 months, though the timing can vary. Most babies have noticeable regrowth by their first birthday, often with changes in color or texture.
How can I stop my baby’s hair from falling out?
You can’t fully prevent newborn hair loss, as it’s a natural process. However, minimizing friction by using a soft blanket, gently brushing the hair, and avoiding over-washing can help reduce additional hair shedding. These practices keep the scalp healthy, supporting new hair growth.
How long does it take for newborn body hair to fall off?
Newborn body hair, or lanugo, generally falls off within the first few weeks after birth. This soft, fine hair covers the baby’s body in the womb and typically sheds by 1-4 weeks of age, though some babies may retain lanugo longer, especially those born prematurely.
How long after having a baby do you experience hair loss?
Postpartum hair loss often starts around 2-4 months after childbirth. This temporary shedding, caused by hormonal changes, is common and typically peaks within a few months. Hair growth usually returns to its pre-pregnancy cycle by the time the baby reaches 6-12 months old.
Key Takeaways
Newborn hair loss and regrowth are natural aspects of a baby’s development, and most infants go through this process within the first year. While hair may change in color, texture, or thickness, gentle care and patience can support your baby’s scalp health during this phase. Embrace these changes as part of your baby’s unique growth journey, knowing that their hair will grow at its own pace. With proper care and understanding, you can help ensure that your baby’s hair journey is smooth and healthy.
