AIR BIOLOGY

The hair root is composed of three structures:

The follicle - The living tissue from which your hair grow.

The bulb – A thickened club-shape that is located in the lower part of the hair root.

The papilla – Located at the bottom portion of the follicle and it contains the blood supply to keep the hair alive.  Within the hair papilla is a rich blood and nerve supply that contributes to the growth and regeneration of the hair.

HAIR GROWTH CYCLES

GROW, REST, SHED & REPEAT!

Hair grows in a series of cycles

As normal, healthy hair grows, each follicle repeats these cycles through three stages, from active to inactive.

Follicles all have the same structure and cycle phases:

1. Growth (Anagen) phase

2. Transitional (Catagen) phase

3. Rest (Telogen) phase

The average growth of healthy hair on the scalp is about 12.7 - 25.4mm (½ - 1 inch) per month.

At any given time, as much as 90% of the hair on your head is growing.  

The remaining hair are in the transition or resting phase.
