The Anatomy of Hair

What is the anatomy of hair? 

Hair has different cycles. Think of it as the cycle of life, hair has a cycle of life of 4 phases. 

The first three phases are the growth phase, active phase (anagen), regression phase (catagen), and resting phase (telogen). During this time, the growth occurs until the maturation of hair.

ACTIVE PHASE (ANAGEN)

The dermal papillae are an important part of the hair growth cycle. They send nutrients and signals to follicles, which in turn produce healthy new hairs with their long life span!

REGRESSION PHASE (CATAGEN)

The dermal papillae are now fully developed, telling us that this growth phase is over.

RESTING PHASE (TELOGEN)

The hair follicle goes into hibernation, and while it rests a new growth phase begins.

SHEDDING PHASE (EXOGEN)

The cycle of life, which starts with the shedding old hairs and ends in a new follicle taking their place.
