The causes of hair loss vary from one sex to another. Besides, the causes of losing hair are different from children and adults.
The probability of men suffering from hair loss increase with age. Approximately 40 percent of all American men have visible hair loss by the age of 35. By the age of 60 that percentage grows to 65 percent.
Children, on the other hand, are prone to lose their hair early because of a disease, or a fungal infection, or even an emotional disorder.
So, who are affected by the causes of hair loss? We will consider here, what are the causes of hair loss for men, women, and children. Everyone is exposed to the causes of hair loss.
We will see here, what are the causes of
hair loss for men, women, and children. Then we'll consider some additional
conditions and diseases that also contribute to hair loss or thinning hair in
all groups. If you want see behind the causes of hair loss, you can click
here. Now, let's begin with male group.
Among the causes of hair loss in men, the most common is a hereditary issue called male pattern baldness. As is stated in the U.S. National Library of Medicine, there are other names for this condition, as androgenic alopecia, male pattern alopecia, and pattern baldness.
In some men occurs gradually, as they are getting older. The signs of male pattern baldness are bald spots and a receding hairline.
Another reason why most men lose their hair is an imbalance of a hormone called testosterone. Testosterone is an androgen male hormone.
The imbalance occurs when the
testosterone converts into DHT, or 5a-dihydrotestosterone. In
men, DHT causes the hair follicles to shrink, regress, and die, resulting in
The causes of hair loss in women vary, being the most common a hereditary condition called female pattern baldness, or androgenetic alopecia. While in some men's hair loss occurs gradually, as they are getting older, in women becomes visible as thinning hair.
Androgenetic alopecia is also triggered by the ovary or pituitary gland tumors, because produce by secretion of the androgen hormone, and that causes hair loss in women.
The problem is, another hormone, testosterone, is not exclusive to males, nor is it the result of testosterone becoming DHT. Unfortunately for women, even a small part of this process causes them to suffer hair loss.
If women change the contraception form, from pill to another method, it activates an induced shedding hair stage, because the body reacts to the changes which affect hormones.
Polycystic Ovary Syndrome or PCOS are another condition that causes hair to fall in women. Symptoms include irregular or not having menstrual periods at all, infertility, acne, pain in the pelvic zone, patchy, and discolored skin, and excessive facial or body hair.
Traction alopecia is the
hair loss associated with tight hairstyles, like hair rollers, ponytails,
braids, and other hairstyles that cause tension to the hair.
I know it's difficult to visualize children hair loss as a normal thing, because it's not. In fact, only the 3 percent of the children population have hair loss, bald spots, or some kind of thinning hair.
Children's hair loss is frustrating not only to the children but for their parents as well. The good news is that, in the little ones most causes of hair loss are temporary, and the hair usually grows back by itself. At least, it's refreshing to know that.
If one of your precious child is losing hair, you want to know the causes for sure. Let's check out the list, in alphabetical order, of causes of children's hair loss:

As you can see there are many causes of hair loss in children. Pretty daunting, to say the least. Fortunately,
much of these causes are temporary. Although not the congenital ones. Let's
hope none of these affect your kids.
Another one of the causes of hair loss is the telogen effluvium. This is an alteration of the normal hair cycle, in which the hair continues to grow for two years, then stops, and in two more months it enters the final shedding phase and is visible as thinning hair or excessive hair loss.
The name itself "effluvium" means the same as an outflow or leakage. Dermatologists say this is the second most common way to lose hair. The first one is androgenetic alopecia.
Telogen effluvium is a natural process of the body. But there are two variations of the condition. The first one is telogen effluvium, which is caused by at least 20 reasons. You can check out that in here.
Besides, there's the other
side of the coin, known as chronic telogen
There are several drugs that cause hair to fall out. In fact more than you can imagine! That's why drugs are one of the causes of hair loss. Maybe you were not aware of all the risks involved, when the doctor prescribed that medication for the first time.
The scalp hair growth has four phases. If you want to know what are these, go and read the article: Telogen Effluvium.
The more we take the drug, the more hair we will lose. Therefore, we will see medications for different conditions, in which hair loss is among their side effects.
To see a list of some of them, go to the article: Hair Loss due to Medication.
As I said before, the causes
behind hair loss are many, as well as the list of previous conditions. Now, imagine that I mention all the drugs, that produce
hair loss, among their side effects.
If hair loss is roaming around in your family, there's a good chance that you suffer from one of the more common causes of hair loss. A genetic condition called male pattern baldness. Other name for the condition is hereditary-pattern baldness. So the name says it all.
In women is called, female pattern baldness. The signs are bald spots and a receding hairline. While in women it becomes visible as thinning hair.
Some people believe male pattern baldness, and female pattern baldness, are not really causes of hair loss. They think these are natural conditions, as we age.
But think about it for a moment, if these conditions are natural, why do we worry so much about it? If it's natural we would just accept them, and that's it, but we don't.
Hereditary-pattern baldness is a condition that starts at 20's or 30's and affects the 40 percent of the male population, but almost anyone can experience some degree of hair loss as we age.
Is caused by hormonal
disorders, age, and hereditary reasons. The common believe is that this kind of
pattern baldness comes from the genes of the mother's side, but investigators
say that this condition is caused by the genes of both parents.
Hormones and hair loss are strongly related, especially in women. Changes like pregnancy, childbirth, menopause, perimenopause, polycystic ovary syndrome, or PCOS, and an imbalance of the thyroid gland are one of the causes of hair loss.
Another hormonal imbalance is testosterone converting to DHT or 5a-dihydrotestosterone. Testosterone is an androgen male hormone.
In men DHT causes hair follicles to shrink, regress, and die, resulting in premature balding.
is not exclusive to men, because women also have certain levels of that hormone
in their bodies. Therefore, they also experience the conversion of testosterone
into DHT. Unfortunately for women, even a small part of this process causes
them to suffer hair loss.
The diseases are among the main causes of hair loss. There are external and internal diseases that have a direct or indirect effect on our appearance. Some of them are the responsible for the hair to fall.
Of course, not every disease is exclusive to women, nor to men. So it's time to go to a list of diseases that cause hair loss, or I mean the list. Which ones are these?
· Acute Stress Disorder
· Alopecia Areata
· Lupus, especially Discoid Lupus
· Polycystic Ovary Syndrome or PCOS
· Scalp Diseases
· Trichotillomania or Hair Pulling Disorder
If you examine the list carefully, you will notice that there are some diseases related to the scalp. There are others that are autoimmune. While others are related to emotional issues
Anyway, this is by no means a complete list of the
diseases that cause hair loss. They are the most famous ones or most infamous,
as you do wish to call it. Periodically I will update it to form a more
complete list. But, you can click this link, if you want a more detailed explanation.
It is almost certain that you have hair loss from chemotherapy, if you underwent that treatment. One of the most distressful and unpleasant side effects of chemo and radiation treatments is seeing before your eyes the hair falling. Besides, for many people, sudden hair loss is a sure sign of cancer.
Of course, no one would like to go through that experience. If you want nobody to know you have cancer, you may feel frightened just by thinking that other people notice you are losing your hair.
You may be wondering why hair loss happens when you are undergoing chemotherapy. Simply put, because chemotherapy medications are extremely potent drugs aiming to rapidly destroy the growth of cancer cells.
The problem is that they also attack good cells, including cells that make hair grow.
Chemo or radiotherapy treatments, as well as chemotherapy drugs can damage the cells that cause hair to grow.
This can lead to a certain type of hair loss known as alopecia. It causes you to lose hair not only on the head, but also eyebrows, eyelashes and other parts of your body. If you do not lose your hair completely, it could happen that males your hair thinner.
After starting the chemotherapy, the hair begins to fall around two to four weeks.
Thankfully, usually most of
the time, hair loss is temporary. The re-growth of your hair begins three to
six months after your last chemotherapy, although the texture and shade of your
hair may vary.
Different studies that have been carried out, connect smoking and hair loss, though in an indirect way. There are still many people who smoke, and a great chunk of these don't pay much attention to their negative consequences.
According to Mayo Clinic you can have hair loss from stress. The loss of hair that comes from stress can occur, either due to a very stressful physical, or emotional event such as a divorce, the death of a loved one, injury, illness, surgery, or even serious financial problems.
That hair loss can be seen between 6 weeks to 3 months, since the incident occurred.
There are three types of hair loss due to stress. The first is the telogen effluvium. It occurs when stress forces a large number of hair follicles to enter a resting phase. In a few months, the follicles that remain in that phase, suddenly begin to fall, just by shampooing and combing your hair.
The second is alopecia areata, which occurs when anxiety levels are high. Then the white blood cells attack the hair follicles.
Third and not least is Trichotillomania. This is an irresistible desire to pluck out the hair from the scalp, eyebrows and other parts of the body.
But hair loss can be left
behind, just by keeping stress under control. If stress is controlled, the hair
will re-grow. If you want to know more about hair loss from stress, and to see

Fungal infection of the scalp is the same as ringworm of the scalp. It's also named tinea capitis. Although this is a fungal infection affecting the scalp, it can strike other body regions, like the groin, also called jock itch, and the beard, feet, as in athletes foot, and another skin areas.
