Do you wear headphones for long periods of time? Have you noticed a dent on the top of your head afterward? Well, you are not alone. This phenomenon is often referred to as the “headphone dent.” Many people are concerned about the potential long-term effects of headphone use on the shape of the skull. 

In reality, headphones alone are not capable of permanently denting or deforming your skull. Let’s take a deeper look at what the fuss is all about. 

Can Headphones Dent Your Skull?

Wearing Headphone

The short answer is no; headphones cannot dent your skull. This is because the pressure required to fracture a human skull is far greater than what regular headphones can exert.

According to a study published in the Journal of Neurosurgery, the first signs of skull fracture appear at a load of around 298 pounds (135 kilograms). Another study from the Faculty of Engineering and the Department of Neurosurgery of Tokyo University puts the average at around 520 lbs (236 kg) or 570 pounds (258 kg).

In comparison, the pressure applied by a typical pair of headphones is relatively minor and not enough to cause any harmful alterations to the skull.

Can Headphones Slowly Cause Head Deformation?

Another common concern is whether extended headphone use could gradually change the shape of the skull over time. Fortunately, this is also not possible.

The adult skull stops growing after a certain age. Artificial cranial deformation, where the skull is tightly bound during early childhood, was practiced in some cultures. But this only works on the growing skulls of young babies.

Once the skull has fully developed, it cannot change shape permanently. Even if there is prolonged pressure from headphones.

What Causes the Appearance of “Headphone Dents”?

Headphone Dents

If headphones can’t dent your skull, what is the cause of the dent that many people notice after wearing them for a long period? It is because of the hair and soft tissue beneath the skin, not the bone. 

Headphone Hair

When you wear headphones, the headband applies pressure on your hair. This compresses and flattens the hair and is more noticeable with longer hair. The tips of longer hair tend to fall down and create a layer of air between the ends of the hair and your scalp. 

The combination of pressure, sweat, and grease from your skin can make the hair stick together. This is what appears as a dent on the top of your head. This same phenomenon can occur with other head-mounted accessories, such as hats, beanies, and even helmets.

Soft Tissue Displacement

Even if you have only little to no hair, longer use of headphones can cause temporary dents on the skin. This is because there is a layer of tissue and fat between the skin and the bone. The pressure from the headband can compress and displace this soft tissue.

While this indentation may look concerning, it’s similar to the marks left by glasses on the nose and ears or the temporary pillow marks on your face after a nap. These indentations will go away on their own after the pressure is removed.

How to Get Rid of Headphone Indentations?

If you do notice a temporary indentation on your head after wearing headphones, there are a few things you can do to help it disappear more quickly:

  1. Washing away the sweat and grease that helps the hair stick together can help the indentation caused by “headphone hair” disappear faster.
  2. Gently massaging the indented skin can help improve blood circulation and speed up the process of the area returning to its natural shape.
  3. Giving your head a break from the constant pressure of the headband can prevent deep indentations from forming in the first place.

Can Headphones Affect Ear Shape?

Headphones Affect Ear Shape

No, wearing headphones cannot permanently change the shape of your ears. The human ear fully develops by the age of 7-8, with some minor “ear maturation” continuing up to age 13. Headphones simply don’t apply enough pressure to alter the shape of the ear, even with prolonged use.

The only reason one ear may appear to protrude more than the other after wearing headphones is that the headphones may not be applying pressure evenly across both ears. Ensuring the headband is centered and the fit is adjusted properly can help prevent this issue.

When Should You Worry About Skull Deformities?

While headphones are not responsible for causing permanent skull deformities, there are some rare medical conditions and situations that can lead to changes in the shape of the skull:

  • Congenital skull indentations: These occur in newborns and babies due to uneven skull expansion or the use of aggressive delivery methods.
  • Previous brain surgery: Procedures like craniectomy, where a piece of the skull is temporarily removed, can leave a noticeable indentation.
  • Severe trauma: A significant head injury that causes a depressed skull fracture can also result in a visible dent or indentation.
  • Paget’s disease of the bone: This condition disrupts the normal bone remodeling process, leading to abnormal bone growth and strange shapes.
  • Bone cancer or tumors: Certain types of bone lesions or growths can cause irregularities in the skull’s appearance.

If you notice any persistent or concerning changes in the shape of your skull, it’s best to consult a medical professional to rule out any underlying health conditions.

Adjusting Headphones for Comfort and Preventing Indentations

Adjusting Headphones for Comfort

To avoid the temporary indentations caused by headphone use, here are some tips:

  1. Add extra foam or cushioning to the headband to distribute the pressure more evenly.
  2. Positioning the headband towards the back of your head can help minimize the indentation on the top of your skull.
  3. Ensure the headphones aren’t too tight, as excessive pressure can lead to discomfort and indentations. Loosen or tighten the headband as needed.
  4. Remove your headphones for a few minutes every hour to give your head a break from the constant pressure.
  5. If your current headphones are consistently causing discomfort or indentations, it may be time to invest in a more comfortable pair.

Q: How long does a headphone dent take to go away?

In most cases, the temporary indentation caused by headphones will disappear within 30 minutes to a few hours, depending on the duration and intensity of the pressure.

Q: Can headphones cause hair loss?

No, headphones do not directly cause hair loss. However, excessive tugging or pulling on the hair from poorly positioned headphones could potentially lead to a form of hair loss called traction alopecia.

Q: What are the signs of a serious skull deformity?

Persistent or worsening indentations, unusual bumps or growths, severe headaches, dizziness, vision problems, and balance issues could be signs of a more serious underlying condition and should be evaluated by a medical professional.


In conclusion, the widespread concern about headphones causing permanent dents or deformities in the skull is groundless. While you may notice temporary indentations or impressions on your head after prolonged headphone use, these are harmless and will disappear quickly.

By understanding the true nature of these “headphone dents” and following simple tips to improve comfort and prevent indentations, you can enjoy your music or audio without worrying about long-term consequences to the shape of your skull. Remember, the human skull is remarkably resilient, and regular headphone use has no risk of permanent alteration.
