What is alopecia?

Alopecia is a disease characterized by the partial or total reduction of hair of the scalp or of any other area of the body.


In a scenario of alopecia, the scalp loses a great number of strands of hair, which causes one or several roundly shaped or circular bald spots, shaping what resembles a big coin. Normally, hair doesn’t grow back in these areas.

  • Abundant hair loss while brushing or washing the hair;
  • Softly sliding your hand through the hair and notice an intense loss;

  • Being able to see the scalp easily in some areas of the head;

Androgenetic Alopecia

Also known as pattern baldness, it’s the hair loss caused by genetic factors. This type of alopecia is the most frequent, being responsible for 95% of the cases among men.

It’s associated with a genetic tendency that influences a type of testosterone – dihydrotestosterone (DHT) – that ends up weakening the hair follicle.

Diffuse Alopecia

Progressive hair loss that doesn’t create a complete baldness. In this case, the hair looks weak and lifeless, and the person gets a feeling of scarcity. 

This type of problem can happen, among other factors, due to endocrine causes, problems in the endocrine glands such as hyperthyroidism or hypothyroidism, which is why it’s more common among women. It can also occur due to the use of medication that may influence diffuse hair loss and hair weakening, such as anticoagulants, chemotherapy treatments, psychiatric drugs, oral contraceptives, among others. 

Another factor is nutrition since it’s of the utmost importance for hair health and for the prevention of diffuse alopecia. If the hair doesn’t get the necessary nutrients for its development, it will become dry, breakable, and thin. As a result, eating disorders, such as nervous anorexia or bulimia, also contribute to the development of alopecia. 

Alopecia Areata

It’s characterized by hair loss in the form of round strands in one or several areas of the scalp. It’s caused by autoimmune factors or by a disruption of the emotional system.

Alopecia areata can be recognized through the quick, partial or total loss of hair in several areas of the scalp
