Causes of Hair Loss

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

Who are affected by the causes of Hair Loss?

With age, men are more likely to experience hair loss. Approximately 40 percent of all American men have visible hair loss by 35. By the age of 60, that percentage grows to 65 percent.

On the other hand, by 40, women 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, a fungal infection, or even an emotional disorder.

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

We will examine the causes of hair loss, which affect men, women, and children, but everyone can suffer from 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, 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. 

The U.S. National Library of Medicine states that the condition has other names, such 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 most men lose their hair is an imbalance of a male androgen hormone called testosterone. 

The imbalance occurs when the testosterone converts into DHT or 5a-dihydrotestosterone. DHT causes hair follicles to shrink, regress, and die in men, resulting in premature balding.

Hair Loss in Women Causes

The causes of hair loss in women vary, being the most common 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 become visible as thinning hair.

Androgenetic alopecia is also one of the causes of hair loss, triggered by the ovary or pituitary gland tumors because the secretion of the androgen hormone provokes it, and that causes hair loss in women.

Another hormone, testosterone, is not exclusive to males, nor is it the result of testosterone becoming DHT. Unfortunately for women, even a tiny part of this process causes 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 is 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 challenging to visualize children's hair loss as a regular thing because it's not. Only 3 percent of the children population have hair loss, bald spots, or thinning hair. 

Children's hair loss is frustrating not only to the children but also to their parents. 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 children 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 leading cause of losing hair in men and women alike. It affects more men than women because men have higher testosterone levels, and DHT comes from that hormone.

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

DHT meets both of these definitions well. In the first place, 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 does DHT have an unexpected consequence? You can find out in the article DHT Hair Loss.
