Fact or Fiction?

• a) Cutting the hair makes it grow faster. Fiction. Cutting hair doesn't affect the growth rate at the root.

• b) Thick hair is more resistant to stretching than thin hair. Fiction. While it might seem intuitive, thin hair can often be more elastic and thus more resistant to stretching. The structure and type of hair fibers also play a role.

• c) Wet hair is more vulnerable than dry hair. Fact. Wet hair is weaker and more prone to damage because the hydrogen bonds are temporarily broken.

• d) Negative molecules are more attracted to the hair than positive molecules. Fiction. Hair has a slightly negative charge, so positive molecules are more attracted to it.
