Why do scabs itch?
Scabs itch because your skin is busy fixing itself underneath.

Pip’s answer
- Scabs itch because your skin is busy fixing itself underneath.
- A scab is a little cover that keeps the spot safe while it heals.
- New skin grows and stretches, and that tickly work feels itchy.
- Wow-ee, your body builds new skin all by itself, so try not to scratch!
For grown-ups
A scab forms from dried blood and protects a wound while new skin grows underneath. As healing happens, nerve endings are stimulated and chemicals like histamine are released, which can cause itching. Picking scabs can slow healing and cause scars.
Ask your child: What can you do instead of scratching an itchy scab?
