How Does Hair Grow?
This article will explore different theories of how hair grows and the ins and outs of human and animal hair types.
By the end of this article, you'll be able to take the time to make sure your hair survives future hairstyles!
What is Hair? When we look at the hair on our heads or eyebrows, it seems to appear out of nowhere. Yet, there's a lot of scientific information that goes into why hair grows. The growing cycle of hair begins when a stem cell division begins a process known as mitosis (separation). This division is called mitosis because successive phases of growth are possible. Enlarging portions of fibres from the parent cell will split off to form new cells, which will grow into a smaller amount through division. After this initial stage of growth, the new cells will attach to nearby tissues to form a follicle. The constant process of splitting and growing is called the growth phase.
More than one cell may be needed to increase hair length. When hair is being cut off, the body will try to make sure that a certain amount of it grows back to have a full head of hair so another part can be cut off. Experts believe that the cells responsible for growth are at the root of all hair-growing processes. The human body has many stem cells located in the hair follicle and the skin. These cells are activated when the hair is cut or damaged for various reasons (like an accident) and divided into two new cells. The new enclosure will then grow into a thicker portion of hair.
Hair types: Choosing between different types of hair
Hair growth is not steady for everyone, and it's not always easy to determine what type of hair you might be growing. The first factor that will affect your answer is your genetics - various genes can affect how fast and thick your hairs are and how they grow. Interestingly, hair growth is an entirely natural process, and it is not influenced by vitamin supplements, minerals, or other artificial products.
The second fact that you should understand about hair growth is that there are two types: anagen and telogen phases.
This phase lasts for 2-5 years - it's the active phase of your hair's life, during which it grows around 1cm every month. It's the longest stage in your hair cycle because the growth cells divide rapidly with high energy rates. Experts believe that most of the human body has less than 10 per cent of hair in the anagen phase at any point in time.
This phase lasts for 1-2 months. During this period, the hair follicle is resting and recharging its cells. The telogen stage is when the cells are waiting to go back into the anagen phase to start dividing and multiplying again.
When a lot of hairs are in the telogen phase simultaneously, or if you have had a bad haircut, your hair will seem thin. Many experts believe that it is possible to change which stage your hair will be in by changing your lifestyle habits and environment. We'll discuss this in more detail later, but for now, you must keep these facts in mind if you want to understand whether some techniques work or not.
Hair growth is a complex process that requires a lot of energy and effort from our bodies. During the growth cycle, the body pumps amino acids into the protein cells, and after they're used up, they'll pump more to keep the process going.
The paradox of hair growth is that hair loss can sometimes happen because your body will push out old cells that it no longer needs. The human body generates new tissues all the time, but nutrients are only available in specific amounts. In hair growth, your body will push out cells that are not being used so they can be replaced with fresh new cells. Hair loss may also happen when the hair is clogged by dead skin cells or other types of waste products.
Before falling out, the hair will become thinner and less nourished than usual. However, you can't tell if your hair has thinned out because it can be caused by genetics or other factors.
The process of losing hair is known as telogen effluvium. It results in shorter hairs that become more noticeable as time goes on.
The problem with hair loss and thinning is that it's often hard to spot; females have less testosterone in their bodies, so they usually lose about 50 per cent less hair than males. If you still don't believe that this type of problem exists, then ask your spouse or a close friend if they've noticed any issues with your hair.
What is Alopecia? Even though everyone loses hair all the time, there are certain cases where it's more noticeable. It's possible for inches to fall out during an early stage of growth or when the hair has been damaged because of an accident or bad haircut. When the body experiences severe stress periods, it can also cause a significant change in your hair.
