Hair Growth Cycle

By May 20, 2019 May 21st, 2019 No Comments

There are approximately 100,000 hair follicles on your scalp and the average person typically sheds between 50 – 100 hairs every day, as part of the natural hair growth cycle.

Your hair is attached to your scalp at the base of the follicle by the hair root. This is where the hair grows and is continuously nourished by small blood vessels delivering oxygen and nutrients to the cells. The actual thickness of the hair depends on the size of the hair follicle from which it grows. Like all the hair on our body, each hair on our head follows its own independent 3 phase growth cycle:

– Anagen: The active growth phase

90% of hairs are in active growth at any one time. The growth phase lasts for approx 4 years

– Catagen – The transition phase

During this phase the hair stops growing and the follicle shrinks. This short phase lasts 2-4 weeks.

– Telogen – The resting phase

This is a period of rest and inactivity when the hair has reached the full extent of its growth and the hair falls out. Normally, no more than 10% of hair is in this phase at any one time, which can last up to 3 months before the cycle is repeated.

Unfortunately, through Female Pattern Hair Loss the hair follicle shrinks (miniaturization) and the hair becomes finer. In addition, the growth phase (Anagen – approx. 4 years) becomes shorter and the resting phase (Telogen – approx. 3months) progressively longer, which inevitably leads to sparse hair growth and ultimately to hair loss.

Hair Dr. Follicle Shampoo and Follicle Serum deliver unique growth-factor-mimicking peptides directly into the follicle to extend the growth phase and shorten the resting phase. By doing so, it effectively prolongs the hair life-cycle and significantly increases the volume of hair on the head.
