SUMMARY

The discussion focuses on the unique properties of human hair, particularly when two strands are crossed and appear to be connected. Participants suggest that this phenomenon is not due to static electricity, as both hairs would carry the same charge. Instead, the connection is attributed to the microscopic structure of hair, which features thousands of tiny scales that can interlock, similar to snake scales. This insight highlights the importance of examining hair under a microscope to understand its physical properties better.

PREREQUISITES
  • Understanding of human hair structure
  • Basic knowledge of microscopy techniques
  • Familiarity with static electricity principles
  • Concept of surface tension and friction in materials
NEXT STEPS
  • Research the microscopic structure of human hair and its implications for hair care.
  • Learn about the effects of static electricity on different materials.
  • Explore microscopy techniques for examining biological samples.
  • Investigate the role of surface friction in material interactions.
USEFUL FOR

Biologists, cosmetologists, materials scientists, and anyone interested in the physical properties of human hair.

why when you cross the 2 hairs

the moment you try to break them up, you would see like they are "somehow connected", is that "static electric" ?

Not likely... as far as I know, they would both have the same charge if it was a matter of static. If you examine hairs through a microscope, though, you'll see that they are composed of thousands of little scales like the underside of a snake. In your example, I suspect that the scales are catching on each other.
