Most 1-year-olds who pull their hair are doing something completely normal. At this age, hair pulling is typically a self-soothing behavior, similar to thumb sucking or rubbing a blanket. Babies often twist or gently pull their own hair (or yours) while sucking their thumb, falling asleep, or feeling upset. It feels good to them, and they keep doing it for that reason.
That said, hair pulling exists on a spectrum. In some cases it can become persistent enough to cause noticeable hair loss, which points to something worth paying closer attention to. Here’s how to tell the difference and what you can do about it.
Why It Happens at This Age
Around 12 months, babies are discovering what their hands can do while also navigating big emotions they can’t yet express. Hair pulling checks several boxes at once: it provides a repetitive sensory experience, it gives them something to grip during moments of frustration or tiredness, and the slight tugging sensation can be genuinely calming. The Sydney Children’s Hospitals Network notes that hair pulling in babies between 1 month and 2 years often pairs with thumb sucking as a way to self-soothe before sleep or during distress.
Think of it like the toddler equivalent of twirling your hair while watching TV. It’s an automatic, comfort-seeking habit rather than a sign of pain or emotional problems. Many babies also pull a parent’s hair during breastfeeding or bottle-feeding, simply because their hands are exploring whatever is within reach.
Common Triggers
Even when hair pulling is developmentally normal, certain situations make it more likely. Recognizing these patterns can help you respond effectively.
- Tiredness. Sleepy babies are the most common hair pullers. You may notice it ramps up right before naps or bedtime, often alongside thumb sucking or eye rubbing.
- Frustration or overstimulation. A 1-year-old who can’t reach a toy, can’t communicate what they want, or is overwhelmed by noise and activity may grab at their hair as an outlet.
- Boredom. Repetitive pulling can simply be something to do with their hands, especially during car rides, stroller time, or other low-stimulation moments.
- Comfort-seeking. Some children find the pulling sensation genuinely pleasant and reinforcing, which is why the habit can stick around even when nothing is obviously wrong.
Scalp Irritation as a Cause
Sometimes pulling or scratching at the scalp has a physical explanation. Atopic dermatitis (eczema) on the scalp can be intensely itchy, and a baby who can’t tell you their head itches will simply scratch or pull at the area. If the pulling seems focused on one spot and you notice redness, flaking, or rough patches, eczema is worth considering.
Cradle cap (infantile seborrheic dermatitis) is another common scalp condition in this age group, but it typically isn’t itchy, so it’s less likely to drive hair pulling. If your child’s scalp looks irritated and the pulling seems more like scratching than the rhythmic twisting described above, a skin condition could be the underlying issue.
When Hair Pulling Becomes a Concern
The line between a normal habit and something more significant is usually visible on your child’s head. If your 1-year-old is pulling out enough hair to create thin patches or bald spots, the behavior has crossed into territory that deserves attention. This is called trichotillomania, a repetitive hair-pulling condition now classified among obsessive-compulsive and related disorders.
Trichotillomania has been documented in children as young as 12 months. In one clinical study, the peak age of onset for hair loss was 1 to 2 years, accounting for 36% of the pediatric cases studied. So while it’s not the most likely explanation for your child’s behavior, it’s not rare either.
Signs that distinguish trichotillomania from ordinary baby hair pulling include:
- Visible hair loss. Patchy areas where hair is noticeably thinner or missing.
- Broken or uneven hair. Short, frayed strands mixed in with longer hair in the pulling area.
- Persistence. The behavior continues for weeks or months rather than coming and going.
- Eating the hair. Some children put pulled hair in their mouth. Over time, swallowed hair can form a mass in the stomach, which is a medical concern.
A pediatrician can distinguish trichotillomania from other causes of hair loss, like alopecia areata (an autoimmune condition where hair falls out in round patches). One simple test involves gently tugging on a small group of hairs. In alopecia areata, hairs come out easily, while in trichotillomania, the remaining hair holds firm because the follicles are healthy.
What You Can Do at Home
For the majority of 1-year-olds, the goal isn’t to eliminate the behavior overnight but to gently redirect it while the habit is still young. A few practical approaches tend to work well.
Offer something else for their hands. If your child pulls hair while falling asleep, give them a small stuffed animal, a silky blanket edge, or a textured teething toy to grip instead. The idea is to replace the hair with something that provides a similar sensory experience. Some parents find that keeping their child’s hands loosely occupied with a comfort object during feeding or wind-down time reduces pulling significantly.
Keep hair short or covered. This is a simple physical barrier. Shorter hair is harder to grip, and a soft hat during peak pulling times (like car rides) removes the temptation entirely. It’s not a long-term solution, but it can break the cycle while your child develops other self-soothing habits.
Watch for patterns. Tracking when pulling happens, whether it’s at bedtime, during transitions, or when your child is hungry, helps you address the underlying trigger. A baby who pulls hair mainly when overtired might benefit from an earlier nap schedule more than from any redirection technique.
Stay calm and avoid big reactions. Drawing a lot of attention to the pulling, even negative attention, can accidentally reinforce it. At 1 year old, your child isn’t pulling hair on purpose to upset you. A gentle, matter-of-fact redirection (“here, hold this instead”) works better than a sharp “no.”
What to Expect Over Time
Most babies who pull their hair at 12 months outgrow it. As language develops and emotional regulation improves over the next year or two, children gain other ways to cope with frustration and tiredness. The self-soothing hair pull that feels so alarming at 1 year old often fades on its own by age 2 or 3.
For children who develop trichotillomania, the picture is different. The behavior tends to persist and may require support from a specialist, particularly if it’s causing noticeable hair loss or distress. A pediatrician can assess whether the pulling has moved beyond a normal developmental phase and, if needed, connect you with a behavioral specialist who works with young children.
