Hello, While the wounds from your hair transplant are small, they can still get infected. Scalp folliculitis is one of the most common post-transplant complications. It is caused by bacteria and manifests with bumps, pustules or pimples around your hair follicles, inflammation, redness and pain. Get connected with your surgeon as the infection can be deeper, causing an abscess. Get clinically examined. Your surgeon may prescribe topical or oral antibiotics based on the kind of infection. Underlying scalp infections like seborrheic dermatitis, eczema, scalp psoriasis, etc., must be managed before a hair transplant. However, even with the best prevention, they can still occur and may be itchy. Hair restoration surgery can trigger scalp psoriasis. Be sure to let your surgeon know about any lesions, rashes, scales and plaques that appear on your scalp during recovery, so they can provide proper care instructions. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
