In Week 6, we looked at hair from humans, dogs, and three big cats: Nakobi the cougar, Mama the serval, and Riley the tiger. Big thanks to Carolina Tiger Rescue and Katie Cannon for guest hosting. We asked Katie several questions about Carolina Tiger Rescue and the animals during and after the show. Check out the Q&A with Katie here.
This seems really cool.
Glad you like it! Let us know if you have any questions!
So is hair completely made out of dead skin cells or is it simply the outside structure?
Hi Kayla. Thanks for your question. Most of your hair is dead cells and proteins (mostly keratin). The only living part of your hair is in the follicle, which is below the skin.
For more information, check out this Wikipedia article as well as this more technical article on hair’s structure.
That’s really neat!
We agree. Send us your questions!
I had no idea that hair looked like with the scale pattern. So cool!
I love how there were so many different patterns. Amazing!
Thanks for tuning in Jay!
I have never looked at hair so in depth like this! Learn something new every day!
this is cool! I’ve never got to see hair under a scanning electron microscope. its cool to see how hair has different structures but i can’t feel them.
