There are areas in our body that are known to grow hair, especially after puberty. Some of them are our scalp, our genital area and our armpits. However, as a matter of fact, our whole skin is covered in hair, except for the palms of our hands and the soles of our feet. This hair is often so thin that we cannot see it unless we pay a lot of attention and look very closely.
The thickness and quantity of body hair is controlled by our genes and the presence of male sexual hormones, namely, the androgens. Since men usually have higher male hormone levels than women, they tend to have more body and facial hair. However, there could be an excess of androgens in the body; for example, due to a problem with the glands. When this happens, our bodies cover in abundant hair. This condition is known as hirsutism.
