While a direct hit to the head can cause a nasty bump, it's unlikely to cause a bald spot. Bald spots are usually the result of an underlying condition, such as alopecia or a fungal infection. However, if you notice a small, round bald spot after a head injury, it's important to have it examined by a doctor. It could be a sign of a more serious problem, such as a concussive injury.
If you suffer a blow to the head, it is important to seek medical attention immediately, even if you do not think that the injury is serious. A doctor will be able to assess the extent of the damage and recommend any necessary treatment. In some cases, hair loss from a head injury is only temporary and your hair will eventually grow back. However, in other cases, the hair loss may be permanent.
If you have suffered a head injury and are concerned about potential hair loss, contact a dermatologist or another medical professional. They will be able to evaluate your individual case and offer guidance on what to expect.
If you have a bump on your head, it's important to see a doctor to make sure it's not serious. If the bump doesn't go away or is accompanied by other symptoms, it could be a sign of a more serious condition.
If you have a bald spot after a bump on the head, it's important to see a doctor to make sure there isn't any internal bleeding or other serious injuries. In most cases, the bald spot will eventually grow back on its own.
It's called "traction alopecia", and it occurs when excessive force is applied to the hair follicles.
This can happen from tight hairstyles that pull on the follicles, or from wearing helmets or other headgear that rubs against the skin.
In some cases, traction alopecia is permanent, but it can usually be reversed if caught early enough.
If you think you might have traction alopecia, see a dermatologist for diagnosis and treatment.
