NORMAL HAIR CYCLE
The scalp bears an average of 110,000 hair follicles, which are growing and falling out on a day to day basis. When the balance between growing hair and falling ones is out of balance then hair loss commences leading to baldness.
The hair cycle is made of three phases:
- Anagen phase during which the hair
is growing (± 3 years)
- Catagen phase also called the
transition phase (± 3 weeks)
- Telogen phase during which the hair
is dying and falling (± 3 months), which
is followed by the anagen phase again.
