3 Stages Of Hair Growth Cycle | Jonsson Protein SG

Hair Growth Cycle

The hair growth cycle is made up of three distinct phases, namely Anagen Phase, Catagen Phase and Telogen Phase. Each phase has its characteristics that determine the length of the hair.

Anagen Phase

  • Also known as the Growing Phase, the hair grows continuously for about 2 to 6 years.
  • Tiny blood vessels provide protein and other nutrients to the hair strand, making the hair strands thick.
  • About 80% to 90% of the hair on our scalp are in the Anagen Phase.

Catagen Phase

  • Signals the end of active hair growth and it lasts for 2 to 4 weeks.
  • Hair detaches from the blood supply and the follicle slowly shrinks to about 1/6 of its original size.
  • Approximately 2 to 3% of the hair on our scalp are in the Catagen Phase.

Telogen Phase

  • Also known as the Resting Phase, approximately 50 to 100 strands of hair are shed daily.
  • The affected hair follicles remain inactive for about 3 months before a new cycle starts again.
  • Around 10 to 15% of the hair on our scalp are in the Telogen Phase.

Hair Loss Explained

Interestingly, all three phases occur simultaneously; at any one time, a random number of hair strands on our scalp will be in one of the three phases. That explains why we drop an average of 50 to 100 strands of hair daily. However, when the cycle is disrupted, increased hair fall results and this may lead to hair thinning or hair loss subsequently.
