Where does hair growth occur?
Hair growth occurs on the head, face, and body. The amount and location of hair growth varies from person to person.
Hair on the head grows from follicles in the scalp. Hair on the face grows from follicles in the beard area and mustache area. Hair on the body grows from follicles all over the body.
Each follicle has its own growth cycle. The growth cycle of a follicle can be divided into three phases: anagen, catagen, and telogen.
Anagen is the growth phase of the follicle. The anagen phase lasts between two and six years.
Catagen is the transitional phase of the follicle. The catagen phase lasts two to three weeks.
Telogen is the resting phase of the follicle. The telogen phase lasts two to four months.
At the end of the telogen phase, the follicle enters the anagen phase and the hair growth cycle begins again.

What layer does hair grow from?
What layer does hair grow from?
This is a question that many people have wondered about, and the answer is not as straightforward as you might think. Hair grows out of the skin, but it starts in a different place depending on whether you are male or female.
Male hair growth starts in the hair follicles, which are located in the dermis, the layer of skin just below the epidermis. The epidermis is the top layer of skin, and it is what you see when you look at your skin. The dermis is a thicker layer of skin that contains blood vessels, nerves, and hair follicles.
Female hair growth starts in the dermal papilla, a small structure located in the dermis that contains blood vessels and nerves. The dermal papilla is in contact with the matrix, the tissue that surrounds the hair follicle. The matrix is responsible for the production of hair fibers.
How do I know my hair growth cycle?
There are three stages of hair growth- anagen, catagen and telogen. Each hair on your head goes through all three stages, but at different times. Knowing which stage your hair is in can help you figure out how to best care for it.
The anagen stage is the growth stage. This is when the hair is actively growing and getting longer. The average anagen stage is about three years long, but it can vary from person to person.
The catagen stage is the transitional stage. This is when the hair growth slows down and the hair follicle begins to shrink. The catagen stage usually lasts about two weeks.
The telogen stage is the resting stage. This is when the hair falls out and a new hair begins to grow. The telogen stage usually lasts about three months.
Most people lose between 50 and 100 hairs per day. If you’re losing more than that, it may be a sign that something is wrong. See your doctor if you’re concerned about your hair loss.

Where does all the hair go?
Have you ever wondered where all your hair goes? It’s a question that has puzzled many people over the years. Well, wonder no more! I’m here to tell you where all that hair goes.
First of all, hair is not like other body parts. It doesn’t decompose and it doesn’t get recycled. Once it’s gone, it’s gone for good. So where does it go?
The vast majority of hair is simply swept away by the wind or washed down the drain. A small amount of it may end up in your brush or comb, but most of it just floats away.
Hair is a natural insulator, so it helps to keep us warm in the winter. When it rains, the hair on our heads helps to keep us dry. And when it’s hot, the hair on our heads helps to keep us cool.
So the next time you lose a hair, don’t worry. It’s all going to a good place!
