Can hair follicles fall out along with the shed hair If not what is the black bump at the end of the hair?
The white bump is called the hair bulb. It sits inside the follicle and is the beginning of the hair strand. The hair bulb is where the dead cells that make up hair are connected with live cells from the body. The follicle is part of your skin so it can't "fall out" but it can become damaged. Illness, sun damage, repeated waxing or tweezing are the most common reasons for follicle damage. There are three phases in the life of hair, a growing phase, a resting phase, and a loss phase. Usually, a healthy person will have 90% of their hair growing, 10-14% of their hair resting, and 10% of their hair falling out at any time.

Why does it hurt when you pluck a hair but not when you cut one?
my guess would that because when you pluck a hair it comes out from the root and pulls from your skin/scalp. But when you cut you're not usually cutting from the root. Well, yeah, that seems to be part of it. I would word it this way: It doesn't hurt when you cut hair because hair doesn't have any nerves, but when you pluck hair, you also kind of pull the nerve the hair is attached to.
