Phrenology, the 19th-century pseudoscience, claimed that bumps on the skull could reveal a person's character and intelligence. Modern science has thoroughly discredited these notions, leaving many to wonder, **does skull shape mean anything** at all?

While head shapes vary widely among individuals due to a combination of genetics and environmental factors, the medically "normal" head, or normocephalic, is typically defined as having balanced proportions. This guide will address the common query: **what is a normal head supposed to look like?**, covering infants and adults.

It's a fact that few people have a perfectly spherical head. The question, 'Is it normal for your head to not be completely round?', is a common one, and the answer lies in understanding the complex and natural development of the human skull, which has many potential variations.

Contrary to popular belief, the human skull is not perfectly symmetrical. It is very common for individuals to wonder, 'is it normal for the top of the head to be uneven?', and for most, minor bumps or dents are a normal anatomical variation. The shape of our skull is influenced by many factors, from the pliable bones of infancy to anatomical features that develop over a lifetime.

Facial and cranial asymmetry are common, with up to 46% of healthy babies experiencing some form of asymmetrical head shape. For adults wondering, “Is it normal for my skull to be asymmetrical?”, the answer is often yes, but understanding the cause and knowing when to seek professional advice is essential for your general health.

While the "Back to Sleep" campaign has successfully reduced Sudden Infant Death Syndrome (SIDS) by over 50% since 1992, it has also led to an increase in positional plagiocephaly, or "flat head syndrome," in infants. This raises a common question for many: **Can I fix the shape of my head?**

Did you know that the human skull is made of several bony plates that are connected by fibrous joints called sutures, which can sometimes be felt as grooves? Understanding these anatomical features can help shed light on **why you have a groove on the back of your head**, a common phenomenon that is usually harmless but can sometimes point to an underlying issue.

At birth, a baby’s skull is not a single, solid bone but a collection of flexible plates that allow for rapid brain growth. The fascinating **squiggly lines on a human skull** are actually these movable joints, known as cranial sutures, that eventually fuse together to form a protective helmet.

While the skull is a solid structure, a 2014 study highlighted that skull deformities, though rare, can have numerous underlying causes. Finding a sunken indentation can be alarming, but understanding **what causes sunken skull indentation** is the first step towards a clear path forward, whether it's a minor anomaly or a more serious condition.

An estimated 50% of infants develop some degree of positional plagiocephaly, or a flat spot on the head, often from constant pressure in one position. For adults asking, 'Why is the back of my head flat and dent on top?', the explanation can range from an uncorrected childhood condition to more complex causes like trauma or underlying medical issues that affect the skull's shape over time.
