The Hair Growth Cycle

cycleTo truly understand what types of problems are connected with your lack of hair, you first need to learn the three stages of the hair growth cycle. It is a complicated natural process, but it can easily be explained without the use of complicated scientific words. The goal of the post is to allow the regular individual to understand what happens with his or her hair and why it falls naturally and what happens when things go wrong. The three separate stages that are a part of the hair growth cycle are: Anagen, Catagen and Telogen. Below we will give short explanations of each phase.

1. Anagen Phase

The anagen phase of the hair growth cycle is actually the growing phase.

  • Hair grows faster in summer rather than winter.
  • The average length achieved per month is around an inch.
  • This phase lasts anywhere between three and five years.
  • The anagen phase is longer for Asians and they can grow up to 40 inches of hair in 7 years.

So for us in the UK, we could grow up to 30 inches in 5 years if the phase lasts that long.  On a detailed level what’s happening is cells from the follicle divide and thus contribute to the hair shaft. An unknown signal causes this process to stop and that’s the beginning of the catagen phase.

As we get older the length of this phase shortens making out hair thinner and weaker with each cycle. Viviscal helps combat this by ensuring the right nutrients are getting to the follicles.

2. Catagen Phase

The Catagen phase is actually the shortest lasting only 10 days. This is a transformational phase in the hair growth cycle between the Anagen and Telogen phases. During this part of the process there is no pigment produced and that’s probably the main reason why the follicle stops all hair production. The follicle moves to the surface of your scalp and the dermal papilla is forced to rest. At the same time a new hair is created underneath the old one.

3. Telogen Phase

This is the last phase in the hair growth process and it is called the resting phase. It is the period when your hair is released and falls out. This phases shouldn’t scare you as it is quite normal. There is a break after this that lasts for about 90 days in which the follicle is inactive and your hair stays the same. Around 20% of our hair is in this phase.

After, the whole hair growth process repeats itself. Each follicle has its own individual lifecycle and the process for each follicle starts at different times. If this was not the case, all of your hair would shed in a one day. Instead you are loosing only a small proportion of your hair on any individual day. This number is estimated to be 80-100 hairs per day (80-100 hairs enter the telogen phase every day)

When Things Go Wrong

Problem occur when the hair growth cycle is disrupted. This provokes hair thinning and loss. Reasons for this to happen can be found with metabolic imbalances, bad nutrition or illness. Just remember that if sometimes after 10 ir so days of being sick, excessively stressed or surgery etc you notice large amounts of shedding. it is probably due to the event 10 days earlier. The event causes the Anagen phase to be terminated prematurely and for a large proportion of your hair to start the catagen and telogen phases.
