intralesional steroid injection

 intralesional injection

this method of treatment — the most common form of treatment for alopecia areata — uses corticosteroids that are injected into bare patches of skin with a tiny needle. These injections are repeated about every four to six weeks.
An intralesional steroid injection involves a corticosteroid such as triamcinolone acetonide injected directly into a lesion on or immediately below the skin.
