Practice 3: Your Crowning Glory 

Read the selection, then answer the questions that follow.

(1) Human hair may be curly or straight, and either a blonde-haired person, red, brown, black, white, or a mixture thereof. But everyone's hair is relatively the same in the way it grows.
(2) Hair is a threadlike structure that grows from the skin. Below the scalp, at the bottom of each hair, is a tiny pit called a follicle. It leads down to the hair's root. Cells at the base of the root begin to move up. As they do, they harden and become a strand of hair.
(3) The hair on your head grows in stages. Follicles actively produce hair for three to six years, then rest for about three months. There's an average of 100,000 hairs on the human head, and about 10% are resting at any given time. We lose about 70–100 hairs every day from our resting follicles!
(4) Sometimes it seems your hair grows fast, but it normally grows less than inch (13 mm) a month. Children's hair grows faster than adults' hair, and everyone's hair grows faster in summer than winter!
10. You can conclude that about 90% of the follicles on your head
a. are resting and not producing hair.
b. are too small to hold the root of a hair.
c. are producing hair at this time.
d. have been closed and can't produce a hair.
11. If it is winter, you can conclude that
a. your hair is growing slower than it did last summer.
b. your hair is growing faster than it did last summer.
c. your hair is growing the same as it did last summer.
d. you have fewer follicles than you had last summer
12. What might you logically conclude about the growth of hair in summer?
a. More people get their hair cut in hot summer weather.
b. Cold weather makes plants and hair grow longer
c. Wearing a hat in winter stops hair growth.
d. Heat and sweat make hair grow faster
