Approximately 85 percent of the hair is in this phase at any given moment, and it can last anywhere from months to years. All of the hair is always at different stages of growth. If all of our hair was in one phase at the same time, we would be either bald or have hair for that time period.  

The second stage is the Catagen, a transitional period that lasts around two weeks. During this phase, the hair does not grow. As a result, the follicle shrinks, causing the bulb to separate and begin the rest phase i.e., Telogen. It lasts 5 to 6 weeks and results in the formation of a new hair bulb.

As it grows, a new baby hair forms, pushing out the unshed ones that haven’t already fallen out. Roughly 10 to 15 percent of our hair is in this stage all the time.

How many hair growth cycles do an average person goes through in a lifetime?

The hair will never grow in a single cycle, only through successive ones. It is estimated that each person goes through 20 to 30 hair growth cycles in their lifetime. For that reason, it is expected that they grow thinner and weaker until death.

Besides that, the older we are, the less fiber we produce in the anagen phase, resulting in fewer strands being produced until it eventually stops, and we have to deal with baldness.

In healthy people, 90% of the hair is in the anagen (growth) phase and only 10% in the catagen (rest) or telogen (falling).

If there is a different balance between them, it’s important to visit your dermatologist to look for the real cause of your hair loss and why it is having trouble growing back.

Most of the time, It should be related to the factors mentioned in the article like – lousy eating habits, hormonal changes, lack of care, etc. So, stop being a doctor yourself and go to a dermatologist if needed.
