The anagen phase, also known as the growth phase, is the first part of the hair growth cycle. During this phase the hair root active and begins to produce new hair. Growth occurs through the cooperation of hair follicle cells, blood vessels, and the nutrient-rich papilla cells located at the base of the hair follicle.
In the anagen phase, hair can grow for an average of 2-7 years, although the actual growth time can vary from person to person. During this time, hair grows approximately 1 cm per month, resulting in a total length of 30-100 cm, depending on individual genetic factors.
The length of the anagen phase is influenced by several factors, including genetics, age, hormonal changes, diet and general health. Influences such as pregnancy, certain medications or illnesses can shorten or lengthen the anagen phase.
During the anagen phase, the hair remains anchored to the head and continues to grow. It can be colored, cut, styled and otherwise treated during this phase as it is firmly anchored in the scalp.
After the anagen phase, the hair enters the so-called Catagen phase over which it becomes inactive and is gradually cut off from the blood supply. This is then done by the Telogen phase followed, in which the hair falls out and makes room for new hair.
In summary, the anagen phase is the active growth phase of hair in which new hair is produced. It lasts several years and can be influenced by various factors. During this phase, hair can usually be treated and styled without any problems.
