1. Anatomy and physiology of hair: the foundation of understanding

In order to adequately assess the role of dietary supplements in maintaining hair health, it is necessary to understand their structure and processes that provide their growth and functioning. Hair is a complex structure consisting of two main parts: a hair follicle located in the skin and a hair rod protruding above the surface of the skin.

1.1. Hair follicle:

Follicle is a dynamic structure responsible for hair formation. It is an invagination of the epidermis in the dermis. Inside the follicle there is a hair onion, which contains cells that actively divide and form hair.

• Hair onion: The central part of the follicle containing the cells of the matrix, which are divided and differentiated, forming various layers of the hair. The onion includes a dermal papilla containing blood vessels that feed the matrix cells and regulate hair growth.
• Matrix: A layer of actively dividing cells producing keratin is the main protein that makes up the hair. The hair growth rate and their thickness depend on the activity of the matrix.
• The vagina of the hair follicle: Several layers of cells surrounding the root of the hair and supporting its structure. The vagina consists of internal and external root vaginal.
• Sebaceous glands: They are located next to the hair follicle and selected sebum (sebum), which lubricates the hair and skin, protecting them from drying and external influences.
• Muscle raising hair: A small muscle attached to the hair follicle. The contraction of this muscle leads to a hair raising (the so -called “goose skin”).

1.2. Hair rod:

The rod is the visible part of the hair consisting of three layers:

• Cuticle: The outer layer consisting of overlapping Keratin scales. The cuticle protects the inner layers of the hair from damage. The condition of the cuticle determines the gloss and smoothness of the hair. The damaged cuticle leads to dim, brittle hair.
• Cortical substance (bark): The main layer of the hair, which is up to 90% of its mass. The bark contains keratin fibers that determine the strength, elasticity and color of the hair (melanin).
• Core (Medulla): The central layer of hair, which is not in all types of hair. Medulla contains loose cells and airspace, its role in the hair is not fully studied.

1.3. Hair growth cycle:

Hair growth is a cyclic process consisting of three main phases:

• Anagen (growth phase): Duration from 2 to 7 years. In this phase, the matrix cells are actively divided, and the hair grows about 1 cm per month. About 85-90% of the hair on the head are in the anagen phase.
• Katagen (transition phase): Duration is about 2-3 weeks. In this phase, hair growth slows down, the hair follicle is compressed, and the connection of the hair with the dermal papilla is disturbed.
• Telogen (Phase Salm): Duration is about 3 months. In this phase of the hair, it stops growing and remains in the follicle until it is pushed out by a new hair in the anagen phase. About 10-15% of the hair on the head are in the heterogene phase.

1.4. Hair health factors:

Many factors affect hair health, including:

• Genetics: A genetic predisposition plays an important role in determining the type of hair, their thickness, color and a tendency to loss.
• Age: With age, hair growth slows down, hair is thin and can turn gray.
• Hormones: Hormonal balance has a significant effect on the growth and health of the hair. Hormonal disorders, such as hypothyroidism or polycystic ovary syndrome (PCOS), can lead to hair loss.
• Nutrition: The lack of nutrients, such as protein, iron, zinc, vitamins, can adversely affect the health of the hair.
• Stress: Chronic stress can lead to hair loss (heterogene alopecia).
• Medical conditions: Some diseases, such as autoimmune diseases, fungal scalp infections, can cause hair loss.
• Medicines: Some drugs, such as anticoagulants, antidepressants, can have a negative effect on hair health.
• External factors: Excessive use of hair styling products, heat treatment (hair dryer, iron), chemical curling, hair dyeing can damage the hair structure.

2. What are dietary supplements and how do they work?

Biologically active additives (dietary supplements) are concentrates of natural or identical to natural biologically active substances, designed for direct intake with food or introduction into food products in order to enrich the ration with individual food or biologically active substances or complexes of such substances, as well as to enhance the protection of the body from adverse environmental factors. It is important to understand that dietary supplements are not medicines, but food additives aimed at maintaining health and replenishing the nutrient deficiency.

2.1. Classification of dietary supplements:

Bades are classified according to various criteria, including the composition, form of release and purpose:

• By composition:
  • Vitamin complexes: Contain various vitamins necessary to maintain hair health.
  • Mineral complexes: They contain minerals such as iron, zinc, selenium necessary for the growth and strengthening of hair.
  • Amino acid complexes: Contain amino acids that are building protein (keratin) building blocks, the main component of the hair.
  • Plant extracts: They contain extracts of plants with antioxidant, anti -inflammatory and stimulating hair growth properties.
  • Omega-3 fatty acids: Polyunsaturated fatty acids necessary for the health of the scalp and hair.
  • Probiotics: Living microorganisms that improve the intestinal health and, indirectly, can affect hair health.
• By the form of release:
  • Capsules: Convenient release form, providing an accurate dosage.
  • Tablets: A cheaper release form, but can be less convenient for swallowing.
  • Powders: You can add to drinks or food.
  • Liquid forms: They are quickly absorbed.
• By purpose:
  • To strengthen hair: They contain components that strengthen the structure of the hair and prevent brittleness.
  • To stimulate hair growth: They contain components that stimulate the division of matrix cells and accelerate hair growth.
  • Against hair loss: They contain components that block the effects of dihydrotestosterone (DGT), a hormone causing androogenetic alopecia.
  • To improve the appearance of hair: They contain components that give the hair shine, smoothness and volume.

2.2. The mechanism of action of dietary supplements:

The mechanism of action of dietary supplements depends on their composition. In general, dietary supplements work as follows:

• Filling a deficiency of nutrients: Dietary supplements replenish the deficiency of vitamins, minerals, amino acids and other nutrients necessary for the normal functioning of the hair follicle.
• Improving blood supply to the scalp: Some dietary supplements contain components that improve blood microcirculation in the scalp, which provides the best nutrition of hair follicles.
• Antioxidant Protection: Some dietary supplements contain antioxidants that protect hair follicles from damage to free radicals.
• Hormonal regulation: Some dietary supplements contain components that block the effect of DGT, a hormone that causes an androgenetic alopecia.
• Keratin synthesis stimulation: Some dietary supplements contain amino acids and other components necessary for the synthesis of keratin, the main protein that makes up the hair.

2.3. Bad safety:

The safety of dietary supplements is an important aspect that must be taken into account when choosing them. Bades do not go through the same strict test as medicines. Therefore, it is important to choose dietary supplements from trusted manufacturers with a good reputation.

• Important: Before taking dietary supplements, you need to consult a doctor, especially if you have any diseases or take medications. Some dietary supplements can interact with medicines or have side effects.
• Pay attention to the composition: Study the composition of the dietary supplement thoroughly and make sure that you do not have an allergy to any of the ingredients.
• Observe the dosage: Do not exceed the recommended dosage indicated on the packaging.
• Buy dietary supplements in proven places: Buy dietary supplements only in pharmacies or specialized stores to avoid buying fakes.
• Report the doctor: Be sure to inform your doctor about what dietary supplements you take so that he can take this into account when prescribing treatment.

3. Myths and reality about hair dietary supplements

There are many myths and misconceptions about hair dietary supplements. It is important to distinguish scientific facts from marketing tricks.

3.1. Myth: Bades are a miraculous remedy for hair loss.

Reality: Bades can be useful when hair loss caused by a deficiency of nutrients or other factors, but they are not a miraculous tool and cannot solve all hair problems. Hair loss can be caused by various causes, including genetic predisposition, hormonal disorders, stress, medical conditions and drugs. In such cases, comprehensive treatment is necessary, including consultation with a trichologist.

3.2. Myth: dietary supplements can accelerate hair growth several times.

Reality: Hair growth is a complex process that depends on many factors, and dietary supplements cannot significantly accelerate it. Bades can help improve the condition of the hair and stimulate their growth, but you should not expect the hair to grow several times faster than usual. The normal hair growth rate is about 1 cm per month.

3.3. Myth: Bades are effective for all types of hair loss.

Reality: Bades are effective only in cases where hair loss is caused by a deficiency of nutrients or other factors that dietary supplements can affect. With androgenetic alopecia (hereditary hair loss), dietary supplements can be ineffective, since this form of hair loss is associated with a genetic predisposition and hormonal factors. In such cases, other methods of treatment are necessary, such as minoxidil or finsterida (as prescribed by a doctor).

3.4. Myth: The more expensive it is, the more effective it is.

Reality: The price of dietary supplements is not always an indicator of its effectiveness. It is important to pay attention to the composition of the dietary supplement, the reputation of the manufacturer and consumer reviews. Dear dietary supplements can contain more expensive ingredients or have a more complex formula, but this does not always mean that they will be more effective than cheaper analogues.

3.5. Myth: Bad can be taken uncontrollably.

Reality: Bad must be taken with caution and on the recommendation of a doctor. Some dietary supplements can interact with medicines or have side effects. Exceeding the recommended dosage can be dangerous to health.

3.6. Myth: Bades are just a marketing move.

Reality: Bades can be useful for maintaining hair health, if you choose and take them correctly. However, do not rely only on dietary supplements. It is important to lead a healthy lifestyle, eat right and care for hair.

3.7. Myth: Dietary supplements can return the hair the previous density.

Reality: Bades can improve the condition of the hair and stimulate their growth, but they cannot completely restore lost hair. If the hair follicles died, dietary supplements will not be able to revive them. In such cases, only surgical treatment methods such as hair transplant can help.

3.8. Myth: The result of the reception of dietary supplements is visible immediately.

Reality: It takes time to achieve visible results from taking dietary supplements. Hair growth is a slow process, and in order to evaluate the effectiveness of dietary supplements, it is necessary to take it for several months.
