In life, many people will experience longer eyebrows after the age of 50. Many people think that this is a good phenomenon and a manifestation of longevity. So is this statement correct? What does long eyebrows mean? Next, let's find out together.

Does longer eyebrows equal longevity?

Nowadays, more and more people believe that the length of eyebrows has a certain relationship with lifespan. Therefore, scientists have carried out related research on this issue.

The researchers observed 300 long-lived elderly people. Through the study, they found that 9 of the 300 long-lived elderly people had long eyebrows, and the rest were normal eyebrows . Longevity is not directly related.

What does it mean for men to have "longer eyebrows" after the age of 50? Many people may not know

age factor

The reason why eyebrows change is related to age , because eyebrows are also a kind of body hair. As we all know, human hair will undergo metabolism, and sometimes hair will fall off naturally and grow new ones. The same is true for eyebrows.

After metabolism, old eyebrows will show signs of falling off, and new eyebrows will grow back. However, as you get older, your body's metabolic capacity is relatively weak, and eyebrow metabolism is slow, so it will grow longer.

eating habits

With the improvement of living standards, the usual diet structure is becoming more and more casual. If the diet is not appropriate, it is very likely to stimulate the rapid growth of eyebrows. For example: often eating foods with high hormone content , which will affect the normal secretion of hormones in our body and cause eyebrows. getting longer.

genetic factors

In fact, sometimes eyebrows, like hair, have a certain genetic predisposition , that is to say, when parents have thicker eyebrows, they may also inherit their parents' eyebrows, showing a trend of getting thicker and thicker.

Conversely, if parents have sparse eyebrows, their children will usually have sparse eyebrows too, but this is not absolute, as genetic factors are only one of them.

hormone changes

Whether the body hair is strong is related to the secretion of hormones. The eyebrows are a kind of body hair. If a person's androgen secretion is strong, his hair will be very thick, and the eyebrows will be naturally thick.

Conversely, if a man's hormones are too low, his hair can also be affected and may experience hair loss and thinning eyebrows.
