Otherwise, the situation we are talking about is Is it just an aesthetic coincidence or… Is there a more complex biological mechanism behind it?

In fact, this difference is present in our body There is a very interesting scientific explanation…

Our hair grows in certain cycles.

These cycles begin with the accumulation of cells in the hair follicles and hair strands are formed. on our scalp hair grows because it is nourished by blood circulation and grows about 1.27 centimeters per month.

But this The renewal process doesn’t last forever. The anagen phase, the hair growth phase, lasts only a few years, depending on genetic factors.

The longer the anagen phase lasts the hair also grows so long. This phase can vary from 2 to 6 years.

For example, at the end of the anagen phase, which lasts two years, the hair grows to about 0.48 centimeters in length; In the six-year phase, this length can triple.

Our body hair, unlike the hair on our heads, has a much shorter anagen phase.

in our body The hair growth cycle only lasts a few weeks. For this reason, the hair on our arms and legs cannot grow as long as the hair on our heads.

the hairs on our heads, protect us from the sun’s rays or keep the sweat out of our eyes It is thought to serve a biological purpose, such as

But arms and legs Because our hair does not have such a function, They don’t have to stretch for long.
