The Anagen Phase is the active growth stage of the hair cycle, during which hair follicles produce new hair. This phase is the longest in the cycle, lasting anywhere from 2 to 7 years, depending on genetics, health, and environmental factors.

During the anagen phase, cells within the follicle rapidly divide, pushing the hair shaft upward and out of the scalp. This activity results in continuous growth and determines the ultimate length of the hair.

The duration of the anagen phase varies among individuals and is influenced by factors such as nutrition, hormonal balance, and overall health. For example, scalp hair typically has a longer anagen phase compared to body hair, leading to its greater length.

Promoting a healthy anagen phase is essential for maintaining thick, strong hair. Treatments targeting this phase, such as minoxidil or platelet-rich plasma (PRP) therapy, can stimulate growth and prolong the active period of hair production.
