Section 1: Understanding of hair growth and factors affecting it
1.1 Hair growth cycle: fundamental phases
Hair grows cyclically, passing through the three main phases: anagen, catagen and bodyogen. Anagen is a phase of active growth, which can last from 2 to 7 years, determining the length of the hair. Katagen is a short transition phase lasting 2-3 weeks, when hair growth slows down. Telegogen is a dormant phase that lasts about 3 months, during which the hair remains in the follicle, but does not grow. At the end of the heterogene, the hair falls out, and the cycle begins again with anagen.
1.1.1 Variations of the duration of phases:
Individual differences in the duration of the phases of anagen and heterogene affect the length of the hair and the degree of their loss. In people with an anagen phase, hair, as a rule, does not reach a long length, and the heterogene phase can be more noticeable, leading to a temporary increase in hair loss.
1.1.2 Hair cycle regulation:
The hair growth cycle is regulated by a complex system of hormones, growth factors and signal tracks. Androgens, especially dihydrotestosterone (DGT), play an important role in the development of androgenic alopecia. Other hormones, such as estrogen and thyroid hormones, also affect hair growth.
1.2 Hair growth factors:
Hair growth depends on many factors, including genetics, nutrition, hormonal balance, stress and health status. Understanding these factors is crucial for the development of effective strategies for improving hair growth.
1.2.1 Genetic predisposition:
Genetics plays a significant role in determining the texture of the hair, growth rate and a tendency to baldness. Androgenic alopecia, or male baldness, often has a hereditary character.
1.2.2 Nutrition and deficits of trace elements:
The lack of certain nutrients can adversely affect hair growth. The most important trace elements for hair health include iron, zinc, biotin, vitamin D, B vitamins and proteins.
- Iron: The lack of iron can lead to iron deficiency anemia, which is one of the causes of hair loss.
- Zinc: Zinc is involved in the synthesis of protein and cell division, which is necessary for hair growth.
- Biotin (Vitamin B7): Biotin plays an important role in the metabolism of fats, proteins and carbohydrates necessary for the health of the hair.
- Vitamin D: The low level of vitamin D is associated with hair loss.
- B vitamins B: B vitamins, especially B12 and folic acid, are important for the growth and health of hair.
- Protein: Hair consists mainly of keratin protein, so sufficient protein consumption is necessary for their growth and recovery.
1.2.3 Hormonal balance:
Hormonal changes caused by pregnancy, birth, menopause or thyroid diseases can affect hair growth.
- Androgens: DGT can cause miniaturization of hair follicles in people genetically predisposed to androgenic alopecia.
- Estrogens: Estrogens contribute to hair growth, so a decrease in estrogen levels during menopause can lead to hair loss.
- Thyroid hormones: Hypothyroidism and hyperthyroidism can cause hair loss.
1.2.4 Stress:
Chronic stress can lead to heterogeneous loss when more hair goes into the heterogene phase, which leads to its loss.
1.2.5 Medical conditions and medicines:
Some medical conditions, such as autoimmune diseases, infections and diseases of the scalp, can cause hair loss. Some drugs, such as anticoagulants, antidepressants and chemotherapeutic drugs, can also lead to hair loss.
1.2.6 Age:
With age, hair growth rate slows down, and hair follicles can decrease, leading to thinning of the hair.
1.3 Diagnosis of the causes of hair loss:
Determining the cause of hair loss is the first step towards effective treatment. It is important to consult a trichologist for diagnosis.
1.3.1 Anamnesis:
The doctor will collect an anamnesis that includes information about family history, nutrition, medications and diseases.
1.3.2 Physical examination:
The doctor will examine the scalp and hair to evaluate the degree and nature of hair loss.
1.3.3 Laboratory research:
Blood tests can be prescribed to determine the level of iron, zinc, vitamin D, thyroid hormones and other indicators.
1.3.4 Trichoscopy:
Trichoscopy is a non -invasive method of studying the hair and scalp with a dermatoscope, which allows you to assess the condition of hair follicles and hair structure.
1.3.5 Scalp biopsy:
In rare cases, a scalp biopsy may be required to clarify the diagnosis.
Section 2: Hair growth: composition, action mechanisms and reviews
2.1 Review of the main ingredients of dietary supplements for hair growth:
Bades for hair growth contain various ingredients aimed at maintaining hair health, stimulation of growth and preventing loss.
2.1.1 Vitamins:
- Biotin (Vitamin B7): Participates in the metabolism of fats, proteins and carbohydrates necessary for the health of the hair. Biotin deficiency can lead to hair loss. Reviews of biotin are often positive, especially in people with a deficiency of this vitamin.
- Vitamin D: He plays a role in the growth and differentiation of cells, including hair follicles. The low level of vitamin D is associated with hair loss.
- Vitamin C: It is an antioxidant that protects the hair follicles from damage to free radicals. Participates in the synthesis of collagen necessary for the health of the hair.
- Vitamin E: An antioxidant that improves blood circulation in the scalp and promotes hair growth.
- B vitamins B (B1, B2, B3, B5, B6, B9, B12): Participate in the metabolism of energy and the synthesis of proteins necessary for hair growth.
2.1.2 Minerals:
- Iron: The lack of iron can lead to iron deficiency anemia, which is one of the causes of hair loss.
- Zinc: Participates in the synthesis of protein and cell division, which is necessary for hair growth. Zinc deficiency can lead to hair loss and worsening of the condition of the scalp.
- Selenium: Antioxidant protecting hair follicles from damage. Participates in the synthesis of thyroid hormones, which affect hair growth.
