Causes of hair loss

Hair loss is a physiological phenomenomenon that affects all human beings, regardless of gender, age and race. Studies show that up to one hundred hairs are lost every day.

This phenomenon should not cause any concern, as it is absolutely natural. Each hair goes through a cycle of life characterized by a growth phase (anagen), an involution phase (catagen) and finally a resting phase (telogen), which ends with the hair falling out after gentle pulling. If the life cycle works correctly, there will already be a new one under the lost hair.

At certain times of the year, such as spring and autumn, it is possible to notice a more pronounced fall, which is however physiological.

However, if you notice an excessive increase in hair loss, which leads to the number of hair lost being greater than the amount of hair growing, then it is advisable to consult a specialist, who can help us understand the causes of the fall, and then define an effective therapy.

We analyze below some of the main causes of hair loss and baldness:

Androgenetic alopecia

The main cause of hair loss is the so-called androgenetic androgenetic hair loss, generally known as common baldness. It is a type of hair loss due to the susceptibility of hair loss to the action of androgenic hormons.

It is so widespread that it affects more than 70% of men and 30% of women, and has different thinning patterns depending on the individual, although there are two main ones:

  • Male pattern: characterized by a thinning and thinning of the vertex area that can extend to the front, mid scalp and crown, i.e. the entire upper part of the scalp.
  • Female pattern: generally recognized in women but also affecting men, characterized by a widespread thinning without affecting the frontal line.


Alopecia areata, total and universal

It is a scalp pathology in which the fall is manifested by the formation of hairless patches. In the most severe cases it can extend to the entire scalp (in this case it is called total alopecia), or to the entire body (universal alopecia).

Etiology and pathogenesis are not yet fully recognized by experts, although an immunological matrix and genetics have been identified.



This is a dysfunction of the thyroid in which the body produces a lower than normal amount of hormones. Thyroid hormones are responsible for the growth of skin, nails and hair.

As a result, it is possible that an excessive increase in the number of lost hairs may occur in the presence of this condition.


Seborrheic pencil disease

Intersecting the sebaceous and manifests itself through an important scalp desquamation. An inflammation of the sebaceous glands leads to a lack of essential nutrients to the hair follicles and a consequent hair loss.



It is an autoimmune disease, which therefore affects the immune system, and affects about 1.5 million people worldwide.

Excessive hair loss is one of the symptoms of the disease, in addition to joint pain, fatigue, swelling, fever and anemia. In this case it is recommended to consult a rheumatologist as well as a trichologist.
