You should avoid scratching at a scab so that you do not cause further breaks in the skin, which can disrupt the healing process and increase the risk of infection and scarring. By Kristen Gasnick, PT, DPT September 10, 2022 https://www.verywellhealth.com/why-do-scabs-itch-5181014
To help relieve itching, use a moisturizer to help prevent water loss from the skin and decrease the dryness that can cause itching. Cooling ointments that contain menthol can also help decrease stimulation of the sensory nerves on the skin to help alleviate itching.
To prevent infections, wounds should stay clean and moist. Wounds need moisture to promote the migration of new skin cells over the wound bed, so the wound should be kept moist but not too moist.
Antibiotic skin ointment can be applied topically to an open wound to prevent infection. Covering the wound with a sterile bandage can also help decrease the risk of infection by creating a barrier between your skin and the outside environment.
Scabs form to help your skin heal after injury. However, they do come with discomfort like itching during your recovery process. It’s usually nothing to worry about, but if you think your wound is infected, call your doctor to receive further medical care.
