Causes of Hair Loss

The causes of hair loss vary from one sex to another. Besides, the causes of losing hair are different from children and adults.

Who are affected by the causes of Hair Loss?

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.

Women, on the other hand, by the age of 40 had a 40 percent more visible hair loss. So women, make up a significant part of the population affected by hair loss and thinning hair. 

In the case of children, they are prone to lose their hair early because of a disease, or a fungal infection, or even an emotional disorder.

Young men are not immune also, because 25 percent of the people, who start to see the first signs of hair loss, are the men with less than 21 years old, according to the American Hair Loss Association.

We will examine what are the causes of hair loss, affecting not only men and women, but also children. Because everyone is exposed to the causes of hair loss.

Then, we will consider other conditions and diseases that also contribute to hair loss or thinning hair in all groups. If you want to see the main factors behind hair loss, then you must read Causes Behind Hair Loss.

We'll talk about the causes of hair loss in the three groups mentioned above. Let's start with the first group, males.

Causes of Male Hair Loss

The most common among the causes of hair loss in men, is a hereditary issue called male pattern baldness. 

As stated in U.S. National Library of Medicine, the condition has other names, 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 an androgen male hormone called testosterone. 

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 premature balding.

Hair Loss in Women Causes

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 one of the causes of hair loss, triggered by the ovary, or pituitary gland tumors, because it is caused by the 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.

Another condition that is well known and that mainly affects women is Lupus. You can learn more by going to the Lupus and Hair Loss article.

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, pelvic zone pain, 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.

Children Hair Loss

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 for the little ones, is that 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:

DHT Hair Loss

DHT Hair Loss is the main cause of losing hair in men and women alike. It affects more men than women because men have higher levels of Testosterone, and DHT comes from that hormone.

About 10 percent of testosterone is converted to DHT. The latter is a by-product of the former. By-product means that it is a product obtained from a principal, or it can also have an unexpected consequence. 

DHT meets both of these definitions well. First, because it is a by-product of testosterone and second, because it also produces an unexpected consequence.

Now it all boils down to one question, what does testosterone levels have to do with hair loss, and why is DHT having an unexpected consequence? You can find out in the article DHT Hair Loss.
