Trichology is a branch of dermatology that focuses on the study, diagnosis, and treatment of diseases of the hair and scalp. A trichologist is a physician who specializes in managing hair-related conditions such as hair loss, dandruff, seborrhea, alopecia (baldness), and other disorders. Trichology also addresses issues related to improving hair and scalp health, disease prevention, and corrective therapies.
Main conditions managed in trichology
Alopecia (hair loss). This condition is characterized by partial or complete hair loss. Several types of alopecia are distinguished, including:
- Cicatricial alopecia – hair loss resulting from trauma or skin diseases that lead to the formation of scar tissue.
- Alopecia areata – patchy hair loss caused by autoimmune processes.
- Androgenetic alopecia – the most common form, associated with genetic and hormonal factors.
Seborrheic dermatitis. A chronic inflammatory condition of the scalp associated with increased sebaceous gland activity and the presence of fungi. Seborrheic dermatitis causes itching, redness of the skin, and dandruff formation.
Dandruff. This is the shedding of dead skin cells from the scalp. Dandruff may be a symptom of seborrhea or other scalp disorders. It is often accompanied by itching and discomfort.
Hair fragility and thinning. These problems are related to deterioration of the hair shaft structure, leading to dryness, brittleness, and thinning. They may be caused by external factors (for example, excessive use of heat styling tools) or internal factors (nutritional deficiencies, thyroid disorders).
Trichotillomania. A psychiatric disorder characterized by compulsive pulling out of one’s own hair, resulting in areas of hair loss.
Fungal infections (scalp mycoses). These infections can cause inflammation, itching, and hair loss. The most common include tinea capitis (ringworm) and other fungal infections of the scalp.
Causes of hair problems
- Genetic predisposition. Heredity plays a significant role in the development of conditions such as androgenetic alopecia.
- Hormonal changes. Hormonal imbalances related to pregnancy, menopause, or thyroid diseases may lead to hair loss.
- Nutritional deficiencies. Lack of vitamins and trace elements such as iron, zinc, and biotin can negatively affect hair health.
- Stress. Chronic stress is a common cause of increased hair shedding, as it disrupts regulation of the hair growth cycle.
- Infectious and autoimmune diseases. Autoimmune disorders such as systemic lupus erythematosus or thyroiditis may cause hair loss.
- Medications and chemotherapy. Certain drugs may cause hair loss as a side effect. Chemotherapy is also a common cause of temporary alopecia.
Diagnostic methods in trichology in Belarus
- Trichoscopy. A method of visual examination of the scalp and hair follicles using a dermatoscope that provides magnification. Trichoscopy allows assessment of hair shaft structure, density, signs of damage, scalp condition, and identification of pathological changes.
- Phototrichogram. A diagnostic technique in which a specific area of the scalp is photographed under magnification before and after trimming the hair in that area. After several days, repeat imaging is performed to evaluate hair growth rate and the proportion of hairs in different growth phases.
- Blood tests. The physician may order general and biochemical blood tests to detect hormonal imbalances, anemia, vitamin deficiencies, or trace element deficiencies that can affect hair condition.
- Scalp biopsy. In rare cases, a small sample of scalp skin may be taken for examination to identify autoimmune diseases or infectious processes.
- Spectral hair analysis. A method used to assess the concentration of trace elements in hair. It may help identify mineral deficiencies or excesses that can influence hair growth.
Prevention of hair problems in Belarus
- Proper nutrition. Adequate intake of vitamins and minerals such as iron, zinc, B-group vitamins, and vitamin D is essential.
- Hair care. Use appropriate hair care products and avoid excessive use of heat styling tools and aggressive procedures such as frequent coloring.
- Stress management. Chronic stress negatively affects hair health, so relaxation techniques such as yoga or meditation are recommended.
- Protection from environmental factors. Ultraviolet radiation, air pollution, and hard water can worsen hair condition, so protecting hair from these factors is important.
Trichology services in Belarus are available in leading clinics and medical centers. Experienced specialists help restore hair health and address the underlying causes of hair loss.
Q&A
Если вы заметили сильное выпадение волос, появление залысин, зуд, шелушение или другие изменения на коже головы, рекомендуется как можно скорее обратиться к трихологу. Это поможет своевременно диагностировать проблему и начать лечение.
Некоторые виды выпадения волос, такие как андрогенетическая алопеция, имеют генетическую природу, и их сложно полностью предотвратить. Однако, правильный уход за волосами, здоровое питание, управление стрессом и использование подходящих средств могут замедлить процесс и предотвратить сильное выпадение.
Это наиболее распространённая форма облысения, вызванная генетической предрасположенностью и повышенной чувствительностью волосяных фолликулов к гормону дигидротестостерону (DHT). Она проявляется как у мужчин, так и у женщин и чаще всего приводит к истончению волос на лобной и теменной части головы.
