Hair pulling in a 1-year-old is almost always a normal self-soothing behavior, similar to thumb-sucking or rocking. Toddlers this age are still learning to regulate their emotions and bodies, and repetitive motions like tugging or twirling hair help them do that. It looks alarming, but in most cases it’s a phase that resolves on its own.
It’s Usually Self-Soothing
At 12 months, your child’s brain is developing rapidly, but her ability to manage stress, boredom, and tiredness is still very limited. Hair pulling and twirling give her a repetitive sensory input that feels calming, the same way adults might fidget with a pen or twist a ring. This is especially common during times of stress, boredom, or before bedtime when she’s winding down. For children who tend to be more intense or anxious by temperament, hair pulling can serve as a physical release valve for emotions they can’t yet express with words.
The Bedtime Connection
Many parents notice hair pulling spikes at naptime or bedtime, and that’s not a coincidence. Toddlers often develop “sleep-onset associations,” which are repetitive behaviors that signal to their brain it’s time to sleep. Hair pulling can become one of these associations, especially if sleep is already disrupted. In a study of children under 24 months with hair-pulling behavior, researchers found the habit was closely tied to poor sleep patterns. When parents improved sleep hygiene (consistent bedtime routines, appropriate nap schedules, a calm sleep environment), hair pulling improved significantly over about three months and stayed improved at follow-up.
If your child mostly pulls her hair when she’s tired or falling asleep, that’s a strong clue the behavior is sleep-related rather than a sign of a deeper issue.
Physical Discomfort Can Play a Role
Sometimes what looks like hair pulling is actually your child reaching for a source of pain she can’t tell you about. Ear infections are a classic example. Because toddlers can’t say “my ear hurts,” they tug at or near their ears, and that pulling can extend to hair around the ear area. Teething pain can cause similar reaching and grabbing around the head and face.
If the hair pulling is concentrated on one side, seems to come with fussiness or fever, or started suddenly, it’s worth checking whether an ear infection or new teeth might be the real trigger. Once the discomfort resolves, the pulling typically stops.
How to Redirect the Behavior
You don’t need to stop the underlying need to self-soothe. You just want to give your child a less destructive way to meet that need. A few approaches that work well at this age:
- Offer a sensory substitute. A small stuffed animal with soft fur, a silky blanket edge, or a textured teething toy can replace hair as the thing she reaches for. Keep it available during the times she tends to pull most.
- Gently redirect without reacting strongly. Calmly move her hand away and place the substitute in it. Big reactions (even concerned ones) can accidentally reinforce the behavior by turning it into an attention-getter.
- Tighten up the sleep routine. If pulling happens mostly around sleep, a consistent, calming bedtime routine can reduce the anxiety that drives the habit. Dim lights, a predictable sequence of activities, and an age-appropriate nap schedule all help.
- Keep hair short or pulled back. This is a practical, temporary fix. If there’s less hair to grab, the habit has less opportunity to take hold while you work on other strategies.
When Hair Pulling Becomes a Concern
The vast majority of 1-year-olds who pull their hair outgrow it. But there is a condition called trichotillomania, a compulsive hair-pulling disorder, that affects roughly 1 to 2 people out of every 100. In young children, the key distinction is whether the pulling causes noticeable hair loss. A child with trichotillomania will have visible bald patches or significant thinning, and the behavior persists rather than fading over weeks or months.
At age 1, a formal diagnosis is rare and usually unnecessary. The diagnostic criteria require that the person has tried to stop the behavior and that it causes significant distress or impairment, thresholds that don’t apply well to a baby who’s simply discovered a soothing habit. Still, if you’re seeing actual bald spots, skin irritation on the scalp, or the behavior is intensifying rather than tapering, bring it up with your pediatrician. Early intervention, often focused on parent-guided strategies rather than anything invasive, tends to be very effective at this age.
