- •
Known postmortem root bands (PMRBs) in human hair were characterized at the light and electron microscopy spatial scales.
- •
The PMRB is an interwoven network of gas-filled void spaces.
- •
Degradation to the intermacrofibrillar matrix may be responsible for the void spaces.
- •
In the PMRB region, the layers of the cuticle are not degraded.
- •
There is little degradation perpendicular to the hair length.
