Bringing your baby home is magical, but a few weeks later, you might notice something surprising: that adorable newborn hair is disappearing.
Finding baby hair strands can be alarming, but it’s a natural change that happens during their first year.
Understanding when babies lose their hair helps you know what to expect during this phase. Let’s find out why your baby’s hair falls out and what comes next.
From typical timelines to helpful care tips, we’ll guide you through every stage of your baby’s hair journey.
When Do Babies Typically Lose Their Hair?
Most babies start losing their newborn hair within the first six months of life. The most shedding usually happens around 2-3 months old, but every baby is different.
Some lose hair right away, while others don’t shed much until they’re 4-6 months old. There’s no exact schedule to follow.
New hair typically starts growing back between 3-7 months. By their first birthday, most babies have a full head of hair again. The new hair might look completely different from what they were born with, in terms of color and texture.
Why Babies Lose Their Hair After Birth?
Baby hair loss happens for perfectly normal reasons related to hormones and development. Understanding why this occurs can help you feel more confident during this natural phase of your baby’s growth.
1. Hormonal Changes
During pregnancy, babies receive high levels of hormones from their mothers through the placenta. After birth, these hormone levels drop suddenly, which triggers hair follicles to enter a resting phase.
This hormonal shift is the main reason newborns lose their hair. It’s similar to postpartum hair loss that many mothers experience after giving birth.
2. Telogen Effluvium in Babies
Telogen effluvium is when many hair follicles enter the resting phase at the same time instead of gradually.
This causes sudden shedding, not just a few hairs. In babies, it’s normal and temporary. Hair follicles will naturally restart growth without treatment.
3. Birth Stress
Labor and delivery are physically stressful events for babies, even during healthy births. This stress can alter cortisol and other hormones in your baby’s body.
As your baby adjusts to life outside the womb, their body goes through a physiological adjustment period that can temporarily affect hair growth and cause shedding.
Different Types of Baby Hair Loss
Baby hair loss can look alarming at first, yet most causes are normal, temporary, and related to development. Here is a concise comparison table to clarify key differences.
| TYPE | WHAT IT LOOKS LIKE | CAUSE | SHOULD YOU WORRY? |
|---|---|---|---|
| Friction alopecia | Bald spot on the back of the head | Rubbing on the mattress or seats | No. Resolves once the baby rolls over |
| Cradle cap | Yellow or brown scales | Seborrheic dermatitis | No. Hair may shed with scales |
| Lanugo hair | Fine, soft body hair | Normal prenatal hair | No. Sheds naturally |
| Alopecia areata | Circular bald patches | Autoimmune issue | Yes. Consult a pediatrician |
What Your Baby’s New Hair Will Look Like?
Your baby’s new hair might surprise you because it can look completely different from their newborn hair. Blonde babies often develop brown hair, and straight hair might come in curly or wavy.
The thickness can change, too; fine baby hair might be replaced with thick, coarse strands.
These changes happen because your baby’s genetics and new hormone production determine their permanent hair characteristics.
The hair they were born with was influenced by pregnancy hormones. You’ll start seeing their true hair color and texture emerge between 6-12 months as the new hair grows in.
How to Care for Your Baby’s Hair During Hair Loss?
Proper hair care during shedding can keep your baby’s scalp healthy and comfortable. These gentle practices won’t stop natural hair loss, but they’ll support healthy regrowth.
1. Washing Guidelines
Wash your baby’s hair only 2-3 times per week using tear-free, gentle baby shampoo. Use light massaging motions with your fingertips instead of scrubbing.
This prevents unnecessary stress on the hair follicles. Avoid shampoos with harsh chemicals, fragrances, or sulfates, as these can irritate your baby’s sensitive scalp.
2. What to Avoid
Don’t wash your baby’s hair daily, as this can accelerate hair loss and dry out their scalp. Skip applying oils or lotions unless your pediatrician recommends them.
Never shave or cut your baby’s hair thinking it will grow back thicker—this is a myth. Avoid tight headbands, especially during heavy shedding phases.
3. Reducing Friction
Increase supervised tummy time when your baby is awake to reduce pressure on the back of their head. Always place babies on their backs to sleep for safety, even if this causes temporary bald spots.
Use soft crib sheets and handle your baby’s head gently during diaper changes and feeding.
4. Managing Cradle Cap
Use gentle shampooing techniques to loosen cradle cap scales without forcing them off. A soft baby brush can help remove flakes naturally.
Never pick at or scrape cradle cap, as this can irritate the scalp or cause infection. Apply moisturizing creams only if your doctor recommends them.
When Will Your Baby’s Hair Grow Back?
New hair growth follows a natural timeline that varies from baby to baby. While most babies regrow their hair within the first year, some take a bit longer.
-
Regrowth typically begins between 3-7 months after the initial shedding phase ends. You’ll notice fine, fuzzy hair appearing first, which gradually becomes thicker and longer over time.
-
Most babies have a full head of hair by their first birthday, though the thickness and length vary. Some babies develop thick hair quickly, while others have wispy, thin hair throughout their first year.
-
Some children don’t grow much hair until toddler years, and this is perfectly normal. Genetics plays the biggest role in hair growth speed, so look at family baby photos for clues about your baby’s timeline.
-
You cannot stimulate faster hair growth through special shampoos, oils, or treatments. Adequate nutrition through breast milk or formula provides everything your baby needs for healthy hair development.
-
Delayed hair growth is rarely concerning unless accompanied by other symptoms, such as skin problems or developmental delays. If you’re worried, discuss it with your pediatrician at regular checkups.
When to Call Your Pediatrician?
Most baby hair loss is completely normal, but certain signs warrant a doctor’s visit. Contact your pediatrician if hair loss persists beyond 6 months or if your baby shows no regrowth by 12 months.
Call immediately if you notice circular bald patches, which could indicate alopecia areata, or if hair loss is accompanied by redness, swelling, or skin infections.
Also, reach out if hair loss occurs alongside other symptoms such as poor growth, extreme fatigue, or developmental delays. These could signal nutritional deficiencies or thyroid problems that need medical attention.
Wrapping It Up
Now you know when babies lose their hair and why it happens naturally. Those newborn locks typically shed between 2 and 6 months as hormones adjust, but every baby follows their own timeline.
What grows back might surprise you with a completely different color and texture.
Keep caring for your baby’s scalp gently and watch for any red flags we discussed. Trust the process; beautiful new hair is on its way.
