Most babies go through their first major hair texture change between birth and 6 months, when their newborn hair sheds and is gradually replaced by a different type of hair. But the full transition can take much longer. Many children don’t settle into their more permanent hair texture until age 2 or even later, and some experience additional shifts well into childhood.
The Newborn Shedding Phase
The very first hair your baby grows actually starts forming around 14 weeks of gestation. This early hair is often extremely fine and downy, and it’s shaped by the hormonal environment of the womb. Once your baby is born and no longer exposed to those maternal hormones, this newborn hair enters a resting phase and begins to fall out.
This shedding is a normal process called physiological effluvium of the newborn. It typically begins in the first few weeks of life and can last up to about 6 months. Some babies lose hair gradually, so you barely notice, while others shed in visible patches or clumps. The back of the head is a common spot for thinning, partly because of friction from lying on their back. The hair that grows in afterward often looks and feels completely different from what your baby was born with.
When the New Texture Starts Showing
Between roughly 6 and 12 months, most babies begin growing replacement hair that’s noticeably thicker than what they had at birth. This hair may come in a different color, too. But it’s still not necessarily the texture your child will have long-term.
The bigger texture shift tends to happen during the toddler years, between ages 1 and 3. As your child’s body ramps up production of growth-related hormones, the hair shaft itself gets thicker and the natural pattern becomes more defined. A baby born with straight, wispy hair might develop loose waves. A baby with gentle waves might develop tight curls. In one well-documented example, a baby whose hair had a slight bend at 7 days old had tightly coiled hair by 24 months, along with a color change from deep black to brown.
There’s no single age when texture is “final.” Some children see their hair continue to evolve through preschool and even into puberty, when another wave of hormonal changes can alter thickness and curl pattern again.
What Determines Your Baby’s Hair Texture
Hair texture comes down to the shape of the hair follicle. Round follicles produce straight hair, oval follicles produce wavy hair, and flat or asymmetrical follicles produce curly or coily hair. Your baby’s follicles are set for life, but the hair they produce can change character as your child grows and their hormonal environment shifts.
Genetics is the dominant factor. Research on genotyping shows that about 95% of Black individuals have curly hair, while roughly 12-13% of people with European or Asian ancestry do. If your baby has parents from different ethnic backgrounds, the range of possible textures is especially wide, from straight to wavy to curly to coily, sometimes even on the same head. Studies of biracial hair have found that coily strands are nearly always thicker than wavy strands from the same person.
Shaving Won’t Change the Outcome
A persistent belief in many cultures is that shaving a baby’s head will make the hair grow back thicker or with a better texture. Pediatricians at the University of Utah Health have addressed this directly: it doesn’t work. Hair texture and growth rate are determined by genetics, not by cutting or shaving. What happens after a shave is that the blunt-cut ends of the regrowing hair can feel coarser to the touch, creating the illusion of thicker hair. The follicle itself hasn’t changed at all.
Caring for Hair During the Transition
Baby hair in its first year is delicate, and the scalp is sensitive. How often you wash and what products you use should match the texture that’s emerging.
- Tightly curled or coily patterns tend to be drier. Once-a-week washing is usually enough. Washing more often can strip the natural oils that keep this hair type moisturized.
- Looser curls or wavy hair can handle an extra wash or two per week if needed.
- Straight or fine hair that gets oily may benefit from twice-weekly washing, but daily washing is too much for most babies.
When you do wash, be gentle. Scrubbing the scalp too briskly can irritate the delicate follicles underneath. Use products with as few ingredients as possible during the first year. If your baby’s hair seems dry or you want to smooth it down, a small amount of a natural oil like olive, almond, or jojoba can moisturize both the hair and scalp safely. Skip any products with harsh chemicals or strong fragrances.
Light trims every 6 to 8 weeks during the toddler stage can help manage early tangles and keep the hair healthy as the new texture fills in. This is also the age when cowlicks often become noticeable, which is simply a reflection of how the follicles are angled on your child’s scalp and not something that changes with trimming or styling.
What to Expect Long-Term
The color and texture your child has at age 2 is a much better predictor of their adult hair than what they were born with, but it’s still not a guarantee. Hormonal shifts during puberty represent another common turning point when straight hair can develop waves, or thick childhood curls can loosen. Some people notice texture changes during pregnancy or menopause as well.
If your baby’s hair looks nothing like yours right now, give it time. The first two years involve so much change that the wispy, light fuzz on a 3-month-old tells you very little about the full, textured hair that same child will have as a toddler.
