Hair loss, for many individuals, is associated not only with self-esteem and insecurity, but even with depression. This problem can range from thinning hair, recession of the hairline, to complete loss of hair on the upper and upper side of the head.

Hair loss occurs in more than 60% of the male population and in approximately 10% of the female. Although hair loss increases the risk of damage to the scalp and skin cancer, baldness is a condition, with rare exceptions, treated electively.

Main causes of hair loss

Most capillary losses are associated with age and hormonal changes, and there may also be genetic influence. However, there are a large number of individuals with alopecia (medical term for hair loss) due to an underlying systemic, oncological, psychiatric or infectious disease.

Below are the main causes of hair loss:

  • Heredity: the main cause of hair loss is hereditary, whether male or female. This pattern occurs gradually with advancing age in a predictable way, with an increase in “entrances” in men and a thinning of the hair in women.
  • Hormonal changes and diseases: A wide variety of pathologies can cause temporary or permanent hair loss, including hormonal changes during pregnancy, menopause and thyroid problems . Also included in this category are infections of the scalp and psychiatric conditions that may cause the individual to pull their own hair (trichotillomania).
  • Medicines and supplements: hair loss may be associated with the use of drugs that have alopecia as a side effect. Some of these medications include those used to treat cancer, arthritis, depression, heart problems, gout and high blood pressure . After the drug ceases, the hair may not grow in the same way as before.
  • High stress episodes: individuals may experience thinning and thinning of hair until many months after an event of physical or emotional shock. However, this hair loss is temporary.
  • Hair treatments and hairstyles: some hairstyles that pull the strands too much can cause hair loss called traction alopecia. Hair treatments involving hot oils and other toxic substances can also cause hair loss due to inflammation of the hair follicles. If scarring forms over the affected area, baldness can be permanent.

What are the symptoms?

Hair loss can manifest in different ways depending on its underlying cause. This loss can occur gradually or suddenly and affects only the hair or all body hair. In addition, alopecia can be temporary or permanent.

Some of the main ways that alopecia occurs are:

  • Gradual thinning of the hair on the top of the head;
  • Emergence of circular areas without hair;
  • Sudden hair loss;
  • Shedding of hair throughout the body;
  • Bald areas scattered over the scalp.

When to see the doctor?

Schedule an appointment if there is discomfort related to hair loss and desire to treat it. Talk to your doctor if you notice a sudden, tufted fall while washing or brushing your hair. Sudden hair loss may be the sign of an underlying condition that needs treatment.

What are the risk factors for hair loss?

Among the main factors we can mention:

  • Family history of baldness
  • Advanced age
  • Significant weight loss
  • Diseases like diabetes and lupus
  • Stress
