Its… Fun Fact Friday! Which means- time for more interesting facts about your hair.

Our first fun fact:

Hair is the body’s fastest-growing tissue, second only to bone marrow.

The biological purpose for the hair on our head is to serve as a heat insulator and coolant.  It also helps to protect us from the sun’s UV rays.

On average, the

lifespan of a human hair is 2 to 7 years.

The hair on our scalp goes through 3 phases, the anagen phase, catagen phase, and telogen phase.

Remember, every hair strand is in different phases. If all hair strands were on the same phase schedule, there would be periods where you would be completely bald!

The anagen phase is the active growth phase of hair follicles during which the root of the hair is dividing rapidly, adding to the hair shaft.

During this phase the hair grows about 1 cm every 28 days.

The catagen phase is a short transition stage that occurs after the anagen phase.It is also the end of active hair growth. This phase lasts for about 2–3 weeks.

The telogen phase is the resting phase. The hair follicle is considered dead. It is during this phase that hair shedding will occur.

When the body is subjected to extreme stress, as much as 70 percent of hair can prematurely enter the telogen phase. Read:
