Dents in the skull are abnormal and can indicate a serious medical condition. I first noticed dents in my skull when my hair began thinning and shedding at the onset of menopause.
The largest dent is on the top right side of my skull. It measures about an inch long and half an inch deep. A smaller dent is right behind it. Smaller dents are along my hairline.
The dents and skull depressions concerned me enough to make an appointment with my doctor. She told me not to worry since I didn't have any symptoms and my bloodwork was normal.
The dents in my head are not the result of head trauma. I would remember if I was hit in the head with a hammer or a similar blunt object.

According to Healthline.com, the number 1 cause of dents in the skull is trauma. Other causes are covered below.

Car accidents, falls, or severe blows to the head can cause what’s called a depressed fracture in your skull. A depressed fracture means that a part of your skull has been crushed in toward your brain. This kind of injury requires emergency medical treatment.

Excessive levels of Vitamin A in the blood can cause skull indentations, particularly in children who don't eat a well-balanced diet. Vitamin A is essential for healthy skin, hair, eyes, and more.

5. Congenital skull indentation
Some babies are born with an indentation in their skull. These indentations can be caused by the birth process or forceps used by doctors to extract the baby.
