Scabs also itch for a [reason](https://www.healthline.com/health/why-do-scabs-itch#causes)
New skin growth can also cause itchiness. As collagen cells expand and new skin begins to grow on the wound, it results in a scab. When a scab is dry and crusty, it stimulates an itchy sensation.
These messages of itchiness from your brain are ones that you should ignore. Scratching a wounded area or picking at a scab can tear new skin cells that your body is producing to heal the wound. Scratching the itch can reinjure the wound and set back the healing process.
