Scalp bleeding can have several causes. It's important to determine the underlying reason to receive appropriate treatment.
Common Causes of a Bleeding Scalp
Several conditions can lead to a bleeding scalp. These include:
-
Scalp Psoriasis: This inflammatory skin condition causes itchy, dry skin that can crack and bleed, often accompanied by dandruff-like flaking and reddish patches.

-
Head Injuries: Even minor head injuries can cause bleeding due to the scalp's rich blood supply. Small cuts or large bruises (lumps) are possible. [Source: Seattle Children's, MedlinePlus] More serious head injuries may involve bleeding within the brain or surrounding layers. [Source: MedlinePlus]

Dry Scalp: Severe dryness can lead to cracking and bleeding. Other symptoms might include red patches, temporary hair loss, and burning or soreness. [Source: WebMD]

Acne or Pimples: Breakouts on the scalp can lead to inflammation, resulting in bleeding if scratched or picked. [Source: Cleveland Clinic]
Determining the Cause
Identifying the cause requires careful observation of accompanying symptoms. If you have other symptoms besides bleeding, such as:
- Itching and scaling: This points towards psoriasis or seborrheic dermatitis.
- Redness and inflammation: This could indicate psoriasis, seborrheic dermatitis, or an infection.
- Pain or swelling: This suggests a possible head injury.
- Pus or discharge: This points towards an infection.
It is crucial to consult a doctor or dermatologist for proper diagnosis and treatment. Self-treating can worsen the condition. They can perform a physical examination and potentially order tests to determine the underlying cause and recommend appropriate treatment.
