We have two types of bristles. One is shorter and thinner, namely peach fuzz also called hair. The other is longer and thicker, like our hair, eyelashes or chest hair. terminal hairs. Although peach fuzz is generally more common in children, it covers 30 percent of the female body. 90 percent of men Let us note that it consists of terminal hairs.

Although this distinction varies between women, children and men, be different for everyone or there are some reasons why it is generally concentrated in certain regions.

Humans have reached the form they are today as a result of evolutionary processes that have taken millions of years.

The body of our ancestors; It was covered with a lot of hair for protection against cold weather and external dangers, and even for social communication. Over time, the hair of people; climatic conditions, lifestyle and natural selection decreased due to factors such as. However, there were evolutionary advantages to keeping hair thick and dense in some areas.

For example, the hair on our head helps protect us from the sun, while eyebrows and eyelashes prevent harmful substances such as dust and sweat from entering our eyes. Hair in the armpit and groin area reduces friction It can prevent skin irritations.

The biggest factor in hair growth is hormones.

A group of hormones called androgens is one of the main factors that cause hair growth, especially in men. testosterone, It is one of the most well-known androgens and as levels increase during adolescence, body hair growth increases.

Women also have androgen hormones, but their levels are generally lower than in men. For this reason, hair growth in women is less intense, but in some women it is hormonal imbalances This allows male pattern hair growth to be observed.

Polycystic Ovary Syndrome (PCOS) Such conditions can lead to increased androgen levels in women, which can result in excessive hair growth on areas such as the face, chest, and back.

The density and quality of the hair follicles are also effective.

in different parts of our body density of hair follicles and its quality explains why hair growth is uneven. Each follicle; It follows cycles of growth, rest and shedding. These cycles differ depending on the region.

While hair follicles, for example, have a long growth phase hair on arms and legs has a shorter growth phase. This causes the hair in these areas to become shorter and thinner.

In addition, the follicles in some areas may be more sensitive to hormones. Especially on the face, armpits and follicles in the genital area, More sensitive to androgen hormones. In these areas, thicker and darker hair grows.

Finally, genetic and environmental factors are also important in hair growth.

family history, gender, age and even climate, One of the factors that affects hair density and distribution. While the bodies of people living in warm climates may produce less hair to regulate body temperature through sweating, people living in cold climates may have more hair.
