A flat back of the head often results from external pressure, genetics, or developmental factors affecting skull shape.
Understanding Why the Back Of My Head Is Flat
A flat spot at the back of the head is a condition many notice, especially in infants but sometimes persisting into adulthood. This phenomenon, medically known as plagiocephaly or positional molding, occurs when constant pressure flattens one area of the skull. The human skull is malleable during early life stages, making it susceptible to shape changes based on positioning.
In adults, a flat back of the head may be less common but can still happen due to genetics or prolonged pressure. For infants, it’s often linked to sleep positioning since babies spend much time lying on their backs. While generally harmless, understanding the root causes and implications helps address concerns and explore treatment options if necessary.
Common Causes Behind a Flat Back of the Head
Several factors contribute to why the back of my head is flat. Here are some primary reasons:
1. Positional Plagiocephaly
This condition arises from repeated pressure on one part of an infant’s skull. Since babies have soft bones that fuse gradually, lying too long in one position can cause flattening. The widespread recommendation to place babies on their backs to sleep (to reduce sudden infant death syndrome risks) has increased positional plagiocephaly cases.
2. Congenital Factors
Sometimes, flatness results from conditions present at birth. Premature birth can lead to underdeveloped skull bones that are more vulnerable to deformation. Additionally, intrauterine constraints—limited space in the womb—can cause certain cranial shapes.
3. Craniosynostosis
This is a rare but serious condition where one or more sutures in an infant’s skull close prematurely. It restricts normal growth and leads to abnormal head shapes, including flattening at the back or other areas.
4. Genetics and Natural Variation
Not all flatness signals a problem; some people naturally have flatter occipital regions due to hereditary traits or ethnic cranial shape variations.
5. External Pressure in Adults
For adults experiencing a flat back of their head, long-term pressure from headrests, helmets, or sleeping positions can subtly alter skull contour over time.
The Science Behind Skull Development and Flattening
The human skull consists of several plates connected by sutures—fibrous joints that allow growth during infancy and early childhood. This flexibility is crucial for brain development but also means external forces can reshape the head.
During fetal development and infancy:
- Sutures remain open: Allowing expansion as the brain grows rapidly.
- Cranial bones are soft: Making them pliable under pressure.
- Molding occurs naturally: To ease passage through the birth canal.
If pressure persists on one area—like lying on the back consistently—the bone may remodel slightly, causing flattening in that spot while other areas compensate by bulging outwards.
In adults, sutures have fused completely by early adulthood, so significant reshaping is rare but not impossible with persistent mechanical forces or trauma.
How Common Is a Flat Back of the Head?
Positional plagiocephaly affects approximately 20-30% of infants today due largely to recommended supine sleeping positions introduced since the 1990s for SIDS prevention. Most cases are mild and improve naturally with time and repositioning strategies.
For adults, noticeable flattening at the back of the head is uncommon unless linked to specific causes such as genetics or chronic external pressure.
Here’s a quick overview:
| Age Group | Prevalence of Flat Back Head | Main Cause |
|---|---|---|
| Infants (0-12 months) | 20-30% | Positional molding due to sleep position |
| Toddlers (1-3 years) | <5% | Residual effects from infancy; natural correction ongoing |
| Adults (18+ years) | <1% | Genetics or chronic pressure exposure |
Telltale Signs That Your Back Of My Head Is Flat
Recognizing a flat spot involves visual inspection and sometimes professional assessment:
- Visible flattening: A noticeable indentation or lack of curvature at the base of your skull.
- Asymmetry: One side may appear uneven compared to others.
- Shoehorn effect: The forehead or sides might bulge slightly due to compensatory growth.
- No pain or discomfort: Usually painless unless related to underlying conditions.
- Sensory issues: Rarely associated with hearing or vision problems unless part of syndromic cranial deformities.
If you suspect abnormal flattening beyond cosmetic concerns, consulting a healthcare professional like a pediatrician for infants or a neurologist for adults helps rule out serious conditions like craniosynostosis.
Treatment Options for a Flat Back Of My Head Is Flat Condition
Treatment varies depending on age and severity:
Repositioning Techniques for Infants
Simple changes in how babies lie down can significantly improve mild flattening:
- Tummy time: Encouraging supervised playtime on their stomach strengthens neck muscles and reduces back-of-head pressure.
- Alternate head positions during sleep: Gently turning baby’s head side-to-side prevents constant pressure on one spot.
- Avoid prolonged time in car seats or swings: These keep pressure concentrated on certain areas.
Most infants respond well within months if repositioned early.
Cranial Orthotic Helmets (Helmet Therapy)
For moderate cases not improving with repositioning alone, specially designed helmets help mold an infant’s skull gently over weeks or months by applying corrective pressure patterns.
Helmet therapy requires medical supervision and precise fitting but boasts high success rates when started before 12 months old.
Surgical Intervention for Craniosynostosis
When premature suture fusion causes significant deformity or developmental delays, surgery may be necessary to correct skull shape and allow brain growth unhindered.
This option is rare but critical in severe cases diagnosed early by specialists.
No Treatment Needed for Adults with Mild Flattening
Since adult skull bones are rigid, cosmetic concerns often remain unchanged without surgical options like implants or contouring procedures—which carry risks and costs not typically warranted unless desired for aesthetic reasons.
The Role of Prevention: How To Avoid A Flat Back Of The Head Is Flat Scenario in Infants
Prevention focuses mainly on infant care practices:
- Diverse positioning: Avoid keeping babies in one position too long; alternate between back sleeping with gentle head turns and supervised tummy time.
- Adequate tummy time daily: Build neck strength so babies can move their heads freely.
- Avoid restrictive devices: Limit use of car seats, swings, bouncers where babies’ heads rest against hard surfaces for extended periods.
- Pediatric monitoring: Regular check-ups ensure early detection if any asymmetry develops.
- Cautious swaddling: Ensure swaddling doesn’t restrict movement excessively forcing constant head placement on one side.
These measures greatly reduce risk without compromising safety guidelines designed primarily for SIDS prevention.

Frequently Asked Questions
Why Is the Back Of My Head Flat in Infancy?
The back of your head may be flat due to positional plagiocephaly, which happens when constant pressure is applied to one area of an infant’s soft skull. This is common because babies spend a lot of time lying on their backs, making certain spots prone to flattening.
Can Genetics Cause the Back Of My Head To Be Flat?
Yes, genetics can play a role in the shape of your skull. Some people naturally have a flatter back of the head due to hereditary traits or ethnic cranial variations. This type of flatness is usually harmless and part of normal variation.
Is a Flat Back Of My Head a Sign of a Serious Condition?
While often harmless, a flat back of the head can sometimes indicate conditions like craniosynostosis, where skull sutures close prematurely. If you notice significant asymmetry or other symptoms, it’s important to consult a healthcare professional for evaluation.
How Does External Pressure Affect the Back Of My Head?
External pressure from helmets, headrests, or sleeping positions can gradually flatten the back of the head over time. In adults, prolonged pressure may subtly change skull shape, similar to positional molding seen in infants but less common.
What Are Common Treatments for a Flat Back Of My Head?
Treatment depends on age and cause but may include repositioning techniques for infants or helmet therapy in more severe cases. Early intervention often leads to better outcomes by allowing the skull to reshape naturally as it grows.
The Last Word – Back Of My Head Is Flat Explained Clearly
