Hair Growth Cycle

Did you know that your hair grows in three stages? All the hair on your body grows in cycles, but not every hair is always at the same stage, at the same time. Here are the three stages of hair growth.



Anagen: The Growth Stage

The first stage of hair growth is the Anagen Stage. This is the stage of the cycle where new hair is produced. Approximately 85% of all the hair on the body will be in the growth stage at one time. Since most of the hair on the body is in the Anagen Stage at the same time, it makes it the perfect time in the hair growth cycle to wax.

Catagen: The Regression or Falling Out Stage

The Catagen Stage is the second stage in the hair growth cycle. In this stage, the hair shaft grows upward and detaches itself from the bulb. Once the hair has detached itself from the bulb, its also gets cut off from the blood supply. This means that the hair no longer receives any nutrients or pigment. This is the mean reason why hair in this stage looks dull and unhealthy. Only 2 to 3% of the body's hair will be at this stage at any given time.

Telogen: The Final or Resting Stage

This is the stage in the hair growth cycle when hair is at its fullest size. In this stage, hairs are completely erect in the follicle, allowing the hair to show above the skin's surface. Hair is more likely to either shed or fall out during this stage. Only 15% of the body's hair will be in this stage at any given time.

Fun Fact about Hair Growth: It takes anywhere from 4 to 13 weeks for the hair to grow from the dermal papilla (the base of the hair follicle) to the surface of the skin. Have you ever felt a little leftover stubble after getting waxed? That's because some of the hairs left behind were still in the early Anagen Stage and not long enough to be removed from waxing. With regular waxing every 3 to 4 weeks, you are more than likely to get your hair on the same growing cycle, allowing for optimal waxing results.
