Hair pulling in a 1-year-old is almost always a normal self-soothing behavior, similar to thumb sucking or rocking. At this age, babies discover that tugging on hair produces an interesting sensation, and many use it as a way to calm themselves down, especially before sleep or when upset. While it can look alarming, it rarely signals a medical or psychological problem in children this young.
Self-Soothing and Sensory Exploration
Between about 1 month and 2 years, babies commonly twist or gently pull their own hair (or yours) while sucking their thumb or fingers. It tends to happen at predictable times: while falling asleep, during breastfeeding or bottle feeding, or when your child is overtired, frustrated, or distressed. The repetitive motion and the sensation on the scalp produce a calming feedback loop, much like the way adults might twirl their hair without thinking about it.
Some children are drawn to the sensory experience itself. The slight tingle or pull on the scalp can feel satisfying in a way that’s hard to explain but easy to observe. Kids who are more sensory-seeking in general, meaning they like strong textures, movement, or touch, may gravitate toward hair pulling more than others. This doesn’t mean something is wrong with your child’s sensory processing. A lot of toddlers fiddle with, twist, or pull hair without causing any clear damage, and the habit fades on its own as they develop other ways to self-regulate.
Boredom, Stress, and Emotional Triggers
Even at 1 year old, children respond to their environment in ways that can increase repetitive behaviors. Hair pulling often picks up during transitions: a new sibling, a change in routine, starting daycare, or a period of disrupted sleep. Boredom is another common trigger. If your child tends to pull her hair during quiet moments, like sitting in a car seat or waiting in a high chair, she may simply be looking for something to do with her hands.
Fatigue and frustration are big ones at this age. A 1-year-old has intense feelings but very few tools for managing them. Pulling hair can serve as an outlet for that tension. You might notice it increases on days when naps were skipped or when she’s been overstimulated.
Could It Be Pain or Discomfort?
Sometimes hair pulling that’s focused on one side of the head points to physical discomfort rather than a habit. Ear infections are common in this age group, and one of the hallmark signs is tugging or rubbing at the ear. If the hair pulling is concentrated near the ears and comes with fussiness, trouble sleeping, fever, or irritability, an ear infection is worth considering.
Teething can produce a similar pattern. The referred pain from molars coming in can radiate through the jaw and toward the temples, and a baby who can’t articulate where it hurts may grab at nearby hair instead. If the pulling started suddenly and seems to bother her rather than comfort her, a quick check with your pediatrician can rule out an underlying cause.
When Hair Pulling Becomes a Concern
The line between a normal habit and something that needs attention is usually visible on the scalp. If your child is pulling hard enough to create bald patches, that’s a sign the behavior has moved beyond typical self-soothing. In clinical studies of childhood hair loss, trichotillomania (compulsive hair pulling) accounted for about 7% of cases, and the characteristic pattern is a circular patch of broken hairs at varying lengths, with normal hair surrounding it.
That said, the actual prevalence of trichotillomania in children under 2 remains unknown, and most experts consider it rare at this age. The condition is more commonly diagnosed in older children and adolescents. For a 1-year-old, even noticeable hair pulling is far more likely to be a developmental phase than a disorder.
One thing worth watching for: hair eating. Some children who pull their hair also put it in their mouths and swallow it. Over time, swallowed hair can form a mass in the stomach called a bezoar. These are uncommon in toddlers and can go undetected for years, but if you ever notice hair in your child’s vomit or stool, bring it up with your doctor.
What You Can Do
The most effective approach at this age is redirection rather than correction. A 1-year-old doesn’t understand “stop pulling your hair,” and drawing attention to the behavior can sometimes reinforce it. Instead, try gently moving her hand and offering something else to hold or touch, like a soft blanket, a textured toy, or a stuffed animal with interesting fabric. The goal is to give her hands something equally satisfying to do.
Keeping hair short or pulled back can reduce the opportunity, which is sometimes enough to break the cycle. If the pulling happens mainly at bedtime, a lightweight cap or hood can serve as a physical barrier while you work on replacing the habit with another comfort object.
Pay attention to the timing. If hair pulling clusters around specific situations, like being in the car seat, being put down for a nap, or after a long day, that context tells you what’s driving it. Addressing the underlying trigger, whether it’s boredom, fatigue, or overstimulation, is more effective than trying to stop the pulling in isolation.
For most 1-year-olds, this phase resolves within a few months as language develops and new coping strategies emerge. If the pulling intensifies over time, results in visible hair loss, or is accompanied by other repetitive behaviors that seem difficult for your child to control, a pediatrician or pediatric dermatologist can evaluate the scalp and help determine whether further support would be useful.
