Some people have straight hair and some people have curly hair but why is that?
Hair growth depends on the follicles and therefore the hair is straight, less curly, or more curly.
There are three types of follicles, so there are three types of hair.
Straight hair grows form around follicles.
Wavy hair grows from oval follicles.
Too much curly hair grows from flat follicles.
The number of hairs:
The number of hairs depends on their color. Such as:
Golden Hair:
Those who have golden hair have 140,000 hairs on their head.
Red hair:
People who have naturally red hair have 90,000 hairs on their head.
Black or brown hair
People with black or brown hair have about 110,000 hairs on their head.
Why is hair smooth and soft?
The hair follicles contain an oily gland called the sebaceous gland. This gland oil produces a substance that lubricates and softens the hair.
Why does most people's hair turn gray or white with age?
As we age, our hair turns gray or white because another substance called melanin is found in the hair and when it stops growing, the hair turns white.
