dmatador said:Given that we humans are descended from the great ape, as well as are gorillas and chimpanzees and bonobos, why do we have hair that grows indefinitely, while they do not? I've read something about a sexual selection aspect to evolution, surmising that hair is a means to finding a mate, like strength and intelligence, but I am not completely convinced by this idea.
The hair on a human head grows indefinitely due to the presence of hair follicles, which are tiny pockets on the scalp that contain hair roots. These hair roots are responsible for continuous hair growth as they produce new hair cells.
No, hair growth is not constant for all individuals. It varies based on genetics, age, and health. On average, hair grows about 0.5 inches per month, but this can vary for each person.
While hair growth is mostly determined by genetics, diet and lifestyle can play a role in promoting healthy hair growth. A balanced diet with essential vitamins and minerals, as well as proper hair care practices, can help support hair growth.
The hair on other parts of the body, such as the arms and legs, have a shorter growth cycle because they are considered non-essential for survival. In contrast, the hair on our head has a longer growth cycle as it provides protection and insulation for our scalp.
No, it is not possible to stop hair from growing indefinitely. However, certain medical conditions or treatments, such as chemotherapy, can temporarily halt hair growth. Additionally, regular hair trims can prevent hair from reaching a longer length, but it will still continue to grow.
