Hair growth occurs in cycles. The growth phase, or anagen phase, is the active phase of hair growth, during which the hair grows about 1 cm per month. This phase can last for several years. The transition phase, or catagen phase, is a brief period of hair growth during which the hair stops growing and the follicle shrinks. Finally, the resting phase, or telogen phase, is a period of hair growth during which the hair falls out and a new hair begins to grow in its place. On average, a person loses about 50 to 100 hairs per day due to the telogen phase.
Hair growth is influenced by several factors, including genetics, age, hormonal changes, and overall health. Factors such as poor nutrition, certain medications, and certain medical conditions can also affect hair growth.
Using topical treatments can prolong your hair in it's original state, and prevent loss from occuring at it's natural pace. This, in turn, can lead you to experiencing better long term results. The key is to use these treatments on an on-going fashion, and at least once a day.
