Hair loss can be different for different people. It is seen both in men and women as they age. Whatever the underlying reason for your hair loss may be, it can make the hair loss either gradual or sudden. Hair loss can also be either temporary or permanent. An average human sheds 50 to 100 strands of hair a day. With more than 100,000 hairs in the scalp, losing 100 wouldn’t make much difference. However, when this continues to happen or increase over a period of time, it can become a major problem.

Many things cause hair loss, ranging from unusually high levels of stress to diseases, and there is no single underlying factor that makes people lose their hair. Alopecia, for example, is a condition that causes complete hair loss on the body, but hair is also lost as we age. Similarly, vitamin deficiencies or a poor diet can just as easily rob us of our hair. Medical disorders like thyroid disease and scalp infections, such as ringworm, can also cause hair loss.

Common Causes of Hair Loss

There are many causes of hair loss. Some of the most common ones include the following:


The most common factor for baldness among males and females (more percentage in males) are the hormones and the genes that carry them. In many cases, a hormonal imbalance can even cause permanent hair loss. In males, the testosterone hormone triggers the start of hair loss, whereas, in females, it can be due to pregnancy, childbirth, use of birth control pills or the onset of menopause.

Medical Conditions and Medications

A number of medical conditions like thyroid, or certain skin and scalp infections may cause huge amounts of hair loss. Medications that are used for the treatment of health conditions like cancer, depression, high blood pressure, thyroid, and heart problems can also cause hair loss.

Androgenetic Alopecia

Hereditary factors may also contribute to hair loss in both men and women. In men, the hair loss happens on the scalp and in the case of women, there is a visible thinning over the top and front of the scalp.

Alopecia areata

This is an autoimmune disease where the hair follicles are attacked by the immune system. This generally begins in childhood and if someone in your family suffers from this disease, there is a heightened risk of also having the disease.

Cicatricial (scarring) Alopecia

This is a rare condition wherein the hair follicles are destroyed and scar tissues are formed in place of the follicles.

Poor Nutrition

Hair loss that happens due to poor nutrition is often the result of crash diets and eating disorders. A lack of protein and iron in the diet can also lead to hair loss.

Vitamin A

Excessive consumption of vitamin A can also cause hair loss.


This is a condition where a person feels irresistible urge to pull out their own hair. The sufferers feel a constant urge to pull hair from the scalp, and other parts of the body.


There are other causes such as menopause, stress, and giving birth which that have also been connected to hair loss.

What causes hair loss in women?

The causes of hair loss in men and women are relatively the same, although male pattern baldness does tend to afflict men at a higher rate. Hair loss in women is primarily caused by hormonal shifts, perhaps those that come as part of menopause, as well as vitamin deficiencies and abnormally high levels of stress. This can be a result of your diet or lifestyle, and can, therefore, be remedied in the case of most women.

What causes hair loss in men?

Hair loss in men is often caused by a condition known as male pattern baldness, which affects nearly 80% of men in some way by the time they are 50 years old. This is the gradual thinning of the hair, although hair loss can also happen more rapidly. Aside from MPB, hair loss is also caused by a lack of minerals and vitamins in your diets, such as copper, zinc and vitamin B. Stress and the natural aging process also cause hair loss.

What causes baldness?

Baldness is caused by a myriad of factors, ranging from genetic predisposition to chronic anxiety. Hair growth and strength is closely tied to our dietary choices and nutrient balance in the body, so when there are vitamin deficiencies, such as in the Vitamin B complex, hair loss occurs, eventually leading to baldness. Complete baldness, unless it is the result of alopecia, usually doesn’t happen until a rather advanced age.
