What causes red bumps on the head?
Generally, red bumps on the scalp may be caused by excessive scalp cleansing, climate changes, excessive dandruff, seborrheic dermatitis, folliculitis, or other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a healthcare professional. Specific analysis is as follows:
1. Excessive Scalp Cleansing
Over-cleansing or using shampoo products containing irritating ingredients may disrupt the scalp's natural protective barrier, leading to dryness, itching, and even red bumps. When washing hair, use lukewarm water and avoid excessively hot water that may irritate the scalp.
2. Climate Changes
During seasonal transitions, fluctuations in temperature and humidity can disrupt the balance of scalp oil secretion, resulting in red bumps. Using a mild, non-irritating shampoo and maintaining moderate scalp hydration can help.
3. Excessive Dandruff
Excessive dandruff can accumulate on the scalp, promoting bacterial growth and infection, which may trigger red, swollen bumps. Managing dandruff through anti-dandruff shampoos and a balanced diet can improve the condition.
4. Seborrheic Dermatitis
Seborrheic dermatitis is associated with overactive sebaceous glands and proliferation of Malassezia yeast. Inflammation from this condition may present as red bumps, often accompanied by increased dandruff and itching. Treatment may include antifungal medications such as ketoconazole shampoo, clotrimazole cream, or itraconazole capsules, as prescribed by a doctor.
5. Folliculitis
Folliculitis is primarily caused by bacterial infection. Bacteria may infect hair follicles, leading to red bumps and pustules, often accompanied by pain and pus discharge. Treatment under medical supervision may include topical or oral medications such as mupirocin ointment, amoxicillin capsules, or clindamycin hydrochloride gel.
In daily life, maintain a clean and dry scalp, and avoid friction or squeezing the bumps. Adjust lifestyle habits by ensuring adequate sleep and a light, balanced diet to promote overall skin health.
