It is perfectly normal to lose some hair every day. In fact, the average person loses between 50 and 100 strands of hair per day. But what if you start losing more than that? And what if it is not just a few strands here and there, but clumps of hair coming out in your hands every time you brush or style your hair?

What Are the Main Causes of Hair Loss?
Did you know that there are a lot of different causes of hair loss? In both men and women, hair can fall out for a variety of reasons. Some people might be surprised to learn just how common hair loss is.

The 15 Causes of Hair Loss for Men and Women
1) Cause of Hair Loss: Genetics or Hereditary
Hair loss is a common problem for men and women. But what many people do not know is that hair loss can be started by genetics or hereditary factors. This is one of the most common causes of hair loss, particularly in men. If you have a family member who has experienced hair loss, it’s more likely that you will too.
For men, hair loss is often caused by a condition called male pattern baldness. This is a genetic condition that causes the hair follicles to slowly shrink and produce less hair over time. In some cases, men may even lose all of their hair, but it typically starts with a bald spot or a receding hairline in the corners of your hairline near the temple area.
Women can also experience hair loss due to genetics or hereditary factors. In women, the most common cause of hair loss is a condition called female pattern baldness. This condition is similar to male pattern baldness, but it typically causes the hair to thin out rather than fall out completely.
In the medical world, the correct term is androgenic alopecia for men and women experiencing pattern baldness and if you are experiencing hair loss, it’s important to talk to your doctor. They will be able to determine if your hair loss is due to genetics or another underlying condition.
How Early Can You Experience Hereditary Hair Loss?
Hereditary hair loss is primarily driven by your genetics and the truth is that you can begin to experience hair loss at any age. The earlier you begin to pay attention to the warning signs of hereditary hair loss, the better.
As a woman, if your mother or grandmother experienced hair loss at a young age, you are more likely to experience hair loss yourself. The same is true for men as well. Hereditary hair loss usually occurs gradually and can start as early as your twenties.

One example is the STI known as Syphilis. Not only can it lead to blindness but it can also create patches on your scalp as a result of losing hair on your head, in your eyebrows, in your beard, and anywhere else hair may grow if left untreated; however, it is not the only STI that can cause hair loss.

This is a condition that causes hair to fall out in patches. It can be caused by stress, childbirth, surgery, medications, or even crash dieting.
13) Cause of Hair Loss: Hair Care
If you color, perm, or relax your hair, you could be damaging your hair. Over time, this damage can lead to hair loss.

Many people who have plaque psoriasis develop psoriasis on their scalp at some point. This can lead to hair loss.
