How Your Hair Grows
Normal hair growth occurs in three cycles, these are called Anagen, Catagen and Telogen. Every hair that we grow passes through these three stages.
Every one is a totally different stage of activity
First Phase -Anagen
The growing stage, the Anagen phase should usually last for about 1000 days,this can vary though and there have been cases of it lasting for 6 years. It is during this stage that the hair cells quickly multiply, during this process the hair grows in both length and diameter to its maximum length
Second Phase -Catagen
The Second Growing Phase or ‘Catagen’ is also called the transitional phase, usually lasting one to two weeks, this is the period when the hair actually stops growing before entering the final stage.
Third Phase -Telogen
The Telogen stage is the last or the ‘off stage’, lasting up to 6 weeks,this is when the hair literally remains static or stays dormant. After about 6 weeks this phase comes to its end and new hair starts growing again in the Anagen phase which forces the old hair out
At any given time, at least 85 – 90% of all the hair on your head is in the Anegan or growing stage with the rest usually split between the transitional and resting stage.
Baldness
In the cases of Common baldness, Male pattern baldness or Hereditary hair loss , the body’s genes and hormones effect the follicles and cause them to shrink. This shortens the growing stage and lengthens the final resting or Telogen phase. because of this the hairs become become short and thinner. They will gradually deteriorate until they are no longer visible to the naked eye and the hair follicles eventually close and shut down totally!
