Unexplained bleeding from the head

Generally speaking, unexplained bleeding from the head does not occur. Head bleeding may be caused by trauma, folliculitis, seborrheic dermatitis, tinea capitis (scalp ringworm), or purpura, among other reasons. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment accordingly. Specific analysis is as follows:

1. Trauma

If the head suffers accidental injury—such as impact, abrasion, or laceration—the scalp may break open and capillaries may rupture, leading to local bleeding accompanied by pain. Patients should seek medical attention promptly and use povidone-iodine or hydrogen peroxide solution to disinfect the affected area. It's also important to maintain cleanliness and dryness of the area in daily life, which helps promote recovery.

2. Folliculitis

Folliculitis is an infection of hair follicles on the scalp, which can be caused by bacteria, fungi, or viruses. Inflammation and infection may lead to congestion and rupture of the follicular area, resulting in bleeding from the scalp. Topical medications such as mupirocin ointment or fusidic acid sodium ointment can be applied according to medical advice. Avoid scratching the affected area with hands, and develop the habit of washing hair regularly, which benefits recovery.

3. Seborrheic Dermatitis

Seborrheic dermatitis is a common inflammatory skin condition affecting the scalp, usually triggered by multiple factors such as excessive sebum production or fungal infection. In severe cases, symptoms may include itching, redness, flaking, fragile skin, ulceration, and even bleeding. Patients can use hydrocortisone cream, sulfur ointment, or similar medications under medical guidance to improve symptoms.

4. Tinea Capitis (Scalp Ringworm)

Tinea capitis is a fungal infection of the scalp that manifests as itching, scaling, and inflammation. Scratching and chronic inflammation may damage the scalp skin, leading to bleeding. Treatment options include topical or oral antifungal agents such as terbinafine hydrochloride cream, griseofulvin tablets, or itraconazole capsules, used under a doctor’s supervision.

5. Purpura

Purpura may result from abnormal platelet function, damage to blood vessel walls, or coagulation disorders. Its hallmark features are petechiae (small bleeding spots), ecchymoses (bruises), and subcutaneous bleeding on the skin and mucous membranes. Patients are advised to seek timely medical evaluation and, under physician guidance, may take medications such as vitamin C tablets, cetirizine hydrochloride tablets, or rutin tablets to alleviate symptoms.

In daily life, maintaining a positive and optimistic mindset, adhering to healthy sleep patterns, and properly caring for the skin can support recovery from the condition.
