Trichology is the science that studies hair, hair and scalp, with the aim of solving problems related to them. Appeared in England, it is an area studied until today to deal mainly with conditions such as fall, dandruff, baldness, among others.

To better understand the subject, Hickey solution prepared a complete content with all the important information.


What is trichology?

As mentioned, trichology studies the hair, the causes of hair loss and the problems associated with the scalp. And the specialist, known as a trichologist, performs the assessment to define the cause of the problem and the best treatment for each case.

The word “trichology” comes from the Greek (Trikhos), which means hair. It is an area that lies between dermatology, cosmetology and aesthetic biomedicine. This branch is quite old: it is estimated that it started in the early 1900s.

The trichologist is, in most cases, a doctor specializing in dermatology. But there are technical courses in the area and for that reason there are estheticians, biomedical and pharmacists specialized in the area.

The specialist in trichology analyzes the scalp and hair in a thorough way to arrive at an effective treatment. There are several problems that arise in the structure of the wires, in addition to infections and other diseases that affect the scalp.

Trichologist: when should I go to a hair specialist?

The trichologist analyzes everything that involves the hair, hair and scalp. Therefore, it can be consulted whenever problems arise in these places.

The person who feels irritation, itching, inflammation on the scalp or excessive hair loss, thinning of the strands or any injury should see a trichologist for an evaluation.

It is worth mentioning that the function of a (a) trichologist is quite different from that of a hairdresser. This is because the trichologist is a hair therapist who deeply knows the structure of the hair and scalp, as well as its biological cycle, the main diseases, the amount of hair and the capillary density. The hairdresser is the professional trained to take care of the look and beautification of the threads.

The trichologist can do several specific tests to examine the hair and scalp. This specialist understands how the capillary structure works – the formation of the hair strand and all its parts such as medulla, cortex, cuticle and intercellular cement. And so, it identifies the damage and indicates the most appropriate treatments.

People who have a family history of hair problems of genetic origin should be even more attentive to the first signs. Thus, it is possible to detect the problem early and start treatment as soon as possible.

Loss of hair

It is normal to lose about 50 to 100 hairs a day. But, when the fall is excessive it is important to find out if there are any related health problems.

The hair strands fall out when the hair root is less irrigated by nutrients and blood.

The problem usually occurs due to illness, medication use, inappropriate habits, stressful situations, excessive anxiety , hormonal problems or nutritional deficiencies.


Scientifically known as androgenetic alopecia , baldness can be defined as excessive hair loss. In some cases, it can lead to total or partial loss of hair. It can affect both men and women, but the problem is even more common in men.

Baldness can occur due to genetic or hormonal issues. In women it is common for it to happen due to an excess of male hormones.

There are several forms of treatment such as topical, oral and also laser medications. But, it is important to seek a specialist to identify the causes of baldness.


It is an autoimmune disease that affects the skin, it is chronic and not contagious. Symptoms can be cyclical, that is, they disappear and reappear periodically.

It can reach several parts of the body, including the scalp. In such cases, it may look like dandruff. But larger, thicker, scale-like plaques appear that are more apparent and whitish. These plaques can bleed, cause pain, burning, burning and itching.

The main risk factor is genetic predisposition. Treatment may vary according to the intensity of the symptoms. A specialist usually recommends specific shampoos that should be applied directly to the scalp.

Seborrheic dermatitis

Popularly known as dandruff or seborrhea, it is an inflammation of the skin that causes peeling and redness in some areas of the body such as the scalp. This peeling can loosen and fall into small white fragments.

The health problem is chronic, that is, it may have moments of improvement and worsening of symptoms. This inflammation occurs due to genetic issues, excessive stress , use of some medications and excess oil, as well as due to fungi.

There is still no definitive treatment for seborrhea, but there are specific medications for the skin and scalp that can alleviate the symptoms.


The health problem is a yeast infection that is known scientifically as tinea capillary. It causes symptoms such as severe itching and, in more severe cases, hair loss.

It can be easily transmitted through the use of personal items such as combs, towels, hats, or any item worn directly on the head.

Generally, treatment is carried out with oral antifungal medications and also shampoos. It is also necessary to maintain frequent cleaning of the hair and scalp.

Capillary thinning

Hair can become thinner and thinner due to a number of factors such as hormonal changes and routine habits. However, it is normal for hair to change its thickness throughout life.

And after the age of 50, they may become thinner because of a weakening of the hair follicle, which is the structure formed by the hair and other elements such as the bulb and the sebaceous gland.

In addition, excess chemicals such as dyes and hair dyes make hair thinner. Other habits such as taking too many days to wash your hair, rubbing your hair on the towel hard to dry, using a flat iron and excessive hair dryer tend to make the problem worse.

What treatments can a trichologist undergo?

When going through a consultation with a trichologist, the specialist identifies the problem and indicates what is the best treatment – which varies according to the disease detected.

The specialist in trichology seeks capillary health, acts on detoxification, generates increased oxygenation and favors the distribution of nutrients in the hair.

Generally, the first step is to carry out an evaluation of the scalp and hair with a videodermatoscopy using a scanner.

After the investigation and diagnosis, the trichologist can indicate treatments that aim to help in the distribution of nutrients through the blood circulation and also have bactericidal and fungal actions, in addition to unblocking the hair bulbs.

Before indicating the appropriate treatment, the trichologist makes the diagnosis.

See details below for some treatments indicated by trichologists.

  • Detox: the technique uses specific deep cleansing products that help with hygiene, exfoliation and can regenerate the scalp. It can be performed on all types of hair to reduce flaking and excess oil.
  • Blend of amino acids: application of essential oils that can be used during the treatment of aromatherapy. The aim is to stimulate blood circulation and combat hair loss. They can also have fungicidal, anti-inflammatory, healing and bactericidal action. It can be used in cases of seborrhea, psoriasis, stimulating hair growth, among other problems.
  • Clay therapy: in this case, clay is used to detoxify and balance the pH of the scalp and replenish minerals. It can be indicated to deal with excess chemicals.
  • Lasertherapy: the laser is used as a biostimulator that performs cell renewal and helps in the growth of the hair.
  • Capillary skull massage: performing a capillary massage increases the oxygenation and nutrition of the hair root. By increasing blood circulation, it can prevent the hair from falling out more easily, as it helps in hair regeneration and stimulates hair growth.
  • Micro needling: through a technique with needles, the scalp regenerates. Thus, there is stimulation of hair growth.
  • Carboxitherapy: it is a technique that uses products with vasodilating action, which increases the blood circulation in the scalp. This way, there is more oxygenation and nutrients in the place and the hair grows stronger.
  • Radiofrequency: through moderate heat waves, it promotes the irrigation of the scalp. This stimulation promotes hair growth.
  • Microinfusion of medicines on the skin: it is the application of medicines on the deepest layers of the scalp. It can contribute to baldness and severe hair loss.
  • Hair therapy: uses various manual techniques, devices and cosmetics that help to treat and prevent scalp problems.

It is very important to follow the instructions of the trichologist to have a positive result in the treatment. After managing to control the symptoms, it is often necessary to maintain regular visits to maintain the benefits and control the pathologies.

How much does a consultation with a trichology specialist cost?

Consultation fees may vary according to the specialist’s region: it is usually the price of a medical consultation.

In addition, the value of the technique chosen by the trichologist can also vary – some devices use high technology and can cost around R $ 300 per session. In manual techniques, the value can vary from R $ 80 to 100.
