Hair growth phases
Hair growth phases
It may seem that hair grows all the time. We need to go to the hairdresser regularly so that it doesn't feel unkempt and too far from the style and hairstyle we want. And this is true, but each strand of hair has its different phases - sometimes it grows and sometimes it rests.
It is usually said that hair grows in cycles. Each hair follicle alternates between three different phases – a growth phase, a transitional phase and finally a resting phase. Then the growth phase returns and so the cyclical process continues.
The growth phase
This phase is called with a nicer word the anagen phase. It is during this phase that the hairs form and grow. Approximately 90% of all hairs are in this phase at the same time. This is a long phase that can last for several years and produces a growth of a few tenths of a millimeter each day. It may not sound like much, but in a whole year it is about one decimetre. However, growth can vary individually. It has been established, for example, that if the hair root receives the right nutrients from within (through food and nutritional supplements), the growth rate increases.
Transition phase
Transition phase , which is also called the catagen phase, is the phase in the hair's life when it stops growing and instead prepares to rest. In practice, it is the hair follicle (i.e. the hair's "root") that contracts and ceases to produce growth. This is a relatively short phase of just a few weeks.
The resting phase
During the resting phase (telogen phase) there is no activity in the hair follicle, and so it is for a couple of months. Around 10% of a man's hair is in this phase at the same time. At the beginning of the resting phase, the hair remains attached, but then it comes off completely naturally, for example when you comb or wash your hair. This hair loss is a natural part of the hair's life cycle, and as a rule of thumb it is usually said that about 100 hairs fall out a day completely naturally.
When the hair is detached, the hair follicle prepares to re-enter the growth phase, and then begins to produce a new strand of hair – and so the natural hair growth starts again.
