Bumps in the acute stage of scalp folliculitis are mostly inflammatory papules, which can be treated with physical therapy such as red light and semiconductor laser irradiation in addition to iodine tincture, antibiotic ointment, and oral antibiotics.
Non-acute bumps are mostly hyperplastic keloids or keloids that form after healing. Intradermal injection of tretinoin and compound betamethasone injection can be given to help soften and calm the lesions and improve discomfort such as pain and itching. Or CO2 laser abrasion may be performed as appropriate.
Secondary prevention of scar formation can also be done by topical application of topical silicone gel and other drugs to prevent scar proliferation after surgical excision or combined with superficial X-ray radiotherapy, etc.
