Bad review to stimulate hair growth: scientific analysis and practical recommendations
Chapter 1: Understanding the physiology of hair growth and causes
1.1. Hair growth cycle:
The hair passes through three main phases: anagen (growth phase), catagen (transitional phase) and bodyogen (rest phase). Anagen lasts from 2 to 7 years, determining the length of the hair. Katagen is a short phase that lasts about 2-3 weeks, during which the hair follicle is compressed. Telogen lasts about 3 months, and during this period the hair falls out, freeing up a place for a new hair in the anagen phase. In a healthy person, about 85-90% of the hair is in the anagen phase, 1-2%-in Katagen and 10-15% in the bodyogen.
1.2. Hair growth factors:
- Genetics: A genetic predisposition plays a key role in determining the density, texture and a tendency to loss of hair. Androgenetic alopecia (baldness according to the male type) is a vivid example of genetically determined hair loss.
- Hormonal balance: Hormones, such as dihydrotestosterone (DGT), estrogen and thyroid hormones, have a significant effect on hair growth. DGT is the main hormone responsible for androgenetic alopecia, since it reduces the anagen phase and miniatures hair follicles. The imbalance of estrogen, especially after childbirth or during menopause, can also lead to temporary hair loss. Hypothyroidism and hyperthyroidism can cause diffuse hair loss.
- Nutrition: The lack of necessary nutrients, such as protein, iron, zinc, B vitamins and vitamin D, can negatively affect the health of the hair and lead to their loss. Hair, not vital for the body, receive nutrients in the last turn. Therefore, the deficiency of nutrients is often manifested in the deterioration of the hair.
- Stress: Chronic stress can lead to telogenic effluvia, a state in which a large amount of hair prematurely passes into the bodyogen phase and falls out. Stress can also aggravate other causes of hair loss, such as autoimmune diseases.
- Medical conditions and medicines: Some medical conditions, such as autoimmune diseases (an area of an area, systemic red lupus), scalp infections (stripping lichen) and thyroid disease, can cause hair loss. Certain drugs, including anticoagulants, antidepressants, beta-blockers and chemotherapeutic drugs, can also cause hair loss as a side effect.
- Age: With age, hair follicles become less active, which leads to thinning of the hair and slowing down their growth.
1.3. Types of hair loss:
- Andogenetic alopecia: The most common type of hair loss, characterized by the gradual thinning of the hair on the head of the head in men and the expansion of parting in women.
- Telogen Effluvia: Temporary hair loss caused by stress, illness, pregnancy or medication.
- Alopecia areata: Autoimmune disease causing focal hair loss.
- Traction alopecia: Hair loss caused by constant hair tension (for example, with tight hairstyles, hair extension).
- Rickeeper alopecia: Hair loss caused by damage to the hair follicles and the formation of cicatricial fabric.
Chapter 2: The role of dietary supplements in stimulating hair growth: scientific data and mechanisms of action
2.1. General principles for the use of hair dietary supplements:
Bades (biologically active additives) are aimed at providing the body with the necessary nutrients that support the health of hair follicles and stimulate hair growth. It is important to understand that dietary supplements are not a replacement for a balanced diet and treatment of medical conditions that cause hair loss. They can be a useful addition to a comprehensive approach to hair care. Before taking any dietary supplements, it is recommended to consult a doctor in order to exclude contraindications and interaction with other drugs.
2.2. Key ingredients of hair dietary supplements and their mechanisms of action:
- Biotin (Vitamin B7): Biotin is a cooferment involved in the metabolism of fatty acids, glucose and amino acids. It plays an important role in the synthesis of keratin, the main protein that makes up the structure of hair, skin and nails. Biotin deficiency can lead to hair loss, fragility of nails and skin rashes. Biotin stimulates hair growth, strengthens their structure and improves their appearance. Studies show that the intake of biotin is effective with a deficiency of this vitamin, but its effectiveness at the normal level of biotin in the body is less proved.
- Collagen: Collagen is the main structural protein in the body that provides the strength and elasticity of the skin, hair and nails. With age, the production of collagen decreases, which can lead to thinning of the hair and their brittleness. Reception of collagen additives can help strengthen hair follicles, improve hair elasticity and stimulate their growth. Collagen contains amino acids necessary for the synthesis of keratin.
- Iron: Iron is necessary for transporting oxygen to the cells of the body, including hair follicles. Iron deficiency (iron deficiency anemia) is a common cause of hair loss, especially in women. Reception of iron additives can help restore the normal level of iron in the body and stimulate hair growth. It is important to note that the use of iron should be carried out only with the proven deficiency of iron, since the excess of iron can be harmful to health.
- Zinc: Zinc is involved in many important processes in the body, including protein synthesis, cell division and immune function. It also plays an important role in the health of hair, skin and nails. Zinc deficiency can lead to hair loss, slowing hair growth and scalp problems. Taking zinc additives can help improve the condition of the hair with a deficiency of this mineral.
- Vitamin D: Vitamin D plays an important role in the regulation of hair growth. Studies have shown that the low level of vitamin D can be associated with hair loss, including the alopecia of the area. Taking vitamin D additives can help stimulate hair growth, especially in people with a deficiency of this vitamin.
- B vitamins B: Group B vitamins, such as B12, folic acid and niacin, play an important role in cell metabolism and the health of the nervous system. They are also necessary for the health of hair, skin and nails. B vitamins deficiency can lead to hair loss, slowing hair growth and scalp problems.
- Amino acids (L-cysteine, L-lisine, L-metionine): Amino acids are construction blocks of proteins, including keratin. L-cysteine, L-lysine and L-metionine are important amino acids for hair health. L-cysteine is the main component of keratin. L-Lisin is involved in the assimilation of iron. L-metionine is an antioxidant and protects the hair from damage.
- SAW Palmetto palm extract: Serene palm extract blocks the 5-alpha reductase enzyme, which turns testosterone into dihydotestosterone (DGT). DGT is the main hormone responsible for androgenetic alopecia. A decrease in the level of DGT can help reduce hair loss and stimulate their growth.
- Green tea extract (EGCG): Green tea extract contains an epallocatechin Gallat (EGCG), a powerful antioxidant that can stimulate hair growth and protect hair follicles from damage. EGCG can also block 5-alpha reductase.
- Keratin: Keratin is the main structural protein of hair. Taking keratin additives can help strengthen hair follicles and improve hair structure.
- Omega-3 fatty acids: Omega-3 fatty acids, such as EPA and DHA, have anti-inflammatory properties and can improve the health of the scalp and stimulate hair growth.
2.3. Forms of hair dietary supplements:
Hair dietary supplements are available in various forms of release, including capsules, tablets, powders, chewing sweets and liquids. The choice of release form depends on personal preferences and ease of admission.
2.4. Dosage and duration of dietary supplements:
The dosage and duration of the reception of dietary supplements depend on a specific product and individual needs. It is important to follow the instructions on the packaging and consult a doctor before starting dietary supplements. As a rule, to achieve noticeable results, it is required to take dietary supplements for several months.
2.5. Side effects and contraindications:
Bades can cause side effects, such as stomach disorder, nausea and allergic reactions. Some dietary supplements can interact with medicines. It is important to consult a doctor before taking dietary supplements, especially if you have any medical conditions or you take medicines. Pregnant and nursing women should consult a doctor before taking any dietary supplements.
