Do people shed more hair in summer like animals?

Yes, I know we are animals, but do we lose our winter coats? Do we even have winter coats, or by using clothes has this biological feature been lost to us?

No. Hair is not shed. It's the undercoat that's shed. The undercoat is the super fluffy part of an animal. You can see it if you have a dog or cat by blowing gently on their fur so you can almost see the skin. The top coat is where you see their patterns and most of their coloration. Undercoat looks like a fuzzy, lighter color than the top coat.

Humans don't have this undercoat so we don't shed seasonally.
