Human Hair Growth
Everyone's hair grows differently, depending on age, weight, metabolism,
hormones, ethnicity, medications, and other factors. But all hair goes
through three distinct growth phases:
1) Active growth phase (the anagen phase),
lasts up to several years. At any given time, the majority (85%) of
our body hair is in this phase. During anagen, the hair has an abundance
2) Regressive phase (the catagen phase) lasts about two weeks, during
which the hair stops growing but is not yet shed. About 3 - 4% of our
body hair is in this phase at any given time.
3) Resting phase (the telogen phase), which lasts 5 - 6 weeks, at the
end of which the hair falls out and a new hair begins to form. Approximately
10-13% of our body hair is in this phase at any one time.
An appropriate question people had in
taking Samson’s Secret was the following:
If I take Samson's Secret, will the hair on my arms grow faster and longer, too?
We, at Clayman Company understand and share your
concern. Our research will provide you with a comforting answer. Each
hair on your body grows from its own individual hair follicle. Inside
the follicle, new hair cells form at the root of the hair shaft. As
the cells form, they push older cells out of the follicle. As they are
pushed out, the cells die and become the hair we see.
A follicle will produce new cells for a certain period of time depending on where it is located on your body. This period is called the growth phase. Then it will stop for a period of time (the rest phase), and then restart the growth phase again. When the hair follicle enters the rest phase, the hair shaft breaks, so the existing hair falls out and a new hair takes its place. Therefore, the length of time that the hair is able to spend growing during the growth phase controls the maximum length of the hair.
The cells that make the hairs on your arms are programmed to stop growing every couple of months, so the hair on your arms stays short. The hair follicles on your head, on the other hand, are programmed to let hair grow for years at a time, so the
hair can grow very long.
