Do you notice the hairs in the bathtub or on your comb? Relax, you should not worry!
A whirlpool is the result of two forces acting against each other.
If you find hairs in the bathtub after a shower or you find hairs stuck in your comb, don’t worry; you’re not necessarily going bald. And yet if you kept track of all the hairs you found over a period of a few years, it would seem that what’s left on top must be getting thinner.
