B vitamins for hair growth: role and meaning
I. Foundation: B vitamins and their relationship
B vitamins are water -soluble organic compounds that play a critical role in numerous metabolic processes of the body. They act as coofers, helping enzymes catalyze the biochemical reactions necessary for energy, synthesis of DNA, functioning of the nervous system and, which is especially important for this topic, for the health of hair. Since these vitamins are water -soluble, they do not accumulate in the body in significant quantities and require regular replenishment through a diet or additives. The disadvantage of even one vitamin group B can disrupt the normal functioning of the body and manifest itself in various symptoms, including deterioration in hair condition.
The relationship between group B vitamins is especially important. They often work synergically, enhancing the action of each other. For example, vitamin B12 (cobalamin) requires folic acid (vitamin B9) for proper absorption and metabolism. The imbalance in one vitamin of group B can affect the assimilation and effectiveness of others, which emphasizes the need for balanced consumption of the entire complex. For this reason, when considering the influence of group B vitamins on hair growth, it is important to take into account their interaction, and not to focus exclusively on one vitamin. The manifestation of vitamin B deficiency in the hair can vary, including loss, deceleration of growth, dullness, dryness and brittleness.
II. Tiamin (vitamin B1): Energy for hair follicles
Tiamin, or vitamin B1, is an important coherent in carbohydrate metabolism, which are the main source of energy for body cells. The influence of thiamine on hair growth is associated with its role in ensuring energy for hair follicles. Hair follicles are structures in the skin from which hair grows. They are metabolically active, requiring a constant influx of energy to maintain hair growth and health.
Tiamin is involved in the Crebs cycle (citric acid cycle), which is a central metabolic path that produces energy in the form of ATP (adenosineric). ATP is used by cells to perform various functions, including protein synthesis necessary for the formation of new hair cells. The disadvantage of thiamine can lead to a decrease in energy production, which will negatively affect the functioning of hair follicles. This can lead to a slowdown in hair growth, thinning of hair and even hair loss.
Sources of thiamine include whole grain products, legumes, nuts, seeds and pork. Symptoms of thiamine deficiency may include fatigue, weakness, irritability and neurological problems. The chronic deficiency of thiamine, known as Beri Bury, can lead to serious health consequences, including heart failure and damage to nerves. Although the deficiency of thiamine is rarely found in developed countries, it can occur in people with inferior nutrition, alcohol dependence or certain medical conditions that violate the absorption of nutrients.
III. Riboflavin (vitamin B2): Protection and regeneration of cells
Riboflavin, or vitamin B2, plays a key role in cellular respiration and metabolism of fats, proteins and carbohydrates. It is also important for protecting cells from damage by free radicals. The influence of riboflavin on hair growth is due to his participation in these processes.
Riboflavin is a component of two important coofers: Flavmononucleotide (FMN) and Flavidenindininucleotide (FAD). These coofers are involved in many redox reactions necessary for the production of energy and the synthesis of various biologically active molecules. FAD, in particular, plays a role in the metabolism of fatty acids, which are important to the health of the scalp and hair. Healthy scalp provides an optimal medium for hair growth.
The antioxidant properties of riboflavin are also important for hair health. Free radicals are unstable molecules that can damage the cells, including cells of hair follicles. Damage to free radicals can lead to premature hair aging, thinning of hair and hair loss. Riboflavin helps neutralize free radicals, protecting the hair follicles from damage.
Riboflavin deficiency can lead to various symptoms, including skin inflammation, cracks in the corners of the mouth, photophobia and hair loss. Riboflavin sources include milk, eggs, meat, green leafy vegetables and enriched cereals. With insufficient consumption of riboflavin, additives can be useful for maintaining hair and healthy health.
IV. Niacin (vitamin B3): blood circulation and nutrition of hair follicles
Niacin, or vitamin B3, plays an important role in energy metabolism, the functioning of the nervous system and maintaining skin health. The effect of niacin on hair growth is due to its ability to expand blood vessels and improve blood circulation.
Niacin is involved in the synthesis of two important coofers: nicotinindenindininucleotide (above) and nicotinindinindinicoleotidfosphate (NAS). These coofers are involved in many metabolic reactions, including glycolis, the Krebs cycle and oxidative phosphorylation. They are also important for the synthesis of DNA and RNA necessary for dividing and growth of cells.
Niacin’s ability to expand blood vessels (vasodilation) is especially important for hair health. Improving blood circulation in the scalp provides the delivery of more oxygen and nutrients to hair follicles. This stimulates hair growth and strengthens hair follicles. Insufficient blood circulation in the scalp can lead to a slowdown in hair growth, thinning of hair and hair loss.
Niacin deficiency can lead to Pellagra, a disease characterized by dermatitis, diarrhea and dementia. Symptoms of niacin deficiency may also include fatigue, headaches and hair loss. Sources of Niacin include meat, fish, poultry, peanuts and enriched cereals. Niacin can also be synthesized in the body of tryptophan, amino acids contained in protein foods. However, this process is not always effective, especially with a lack of other nutrients.
V. Pantotenic acid (vitamin B5): moisturizing and hair restoration
Pantotenic acid, or vitamin B5, plays a key role in the metabolism of carbohydrates, fats and proteins. It is also important for the synthesis of Coenzyme A (COA), which is involved in many biochemical reactions, including the synthesis of fatty acids, cholesterol and hormones. The effect of pantothenic acid on hair growth is due to its role in hydration of hair and the restoration of damaged hair.
Pantotenic acid helps maintain moisture in the hair, preventing dryness and brittleness. It also participates in the synthesis of lipids, which are important components of the hair structure. Lipids help protect the hair from damage and give it shine. The disadvantage of pantothenic acid can lead to dryness, brittleness and testing of hair.
Pantotenic acid also plays a role in the restoration of damaged hair. It helps to strengthen the structure of the hair and prevent their further damage. Studies have shown that pantothenic acid can help reduce the split ends and improve the overall type of hair.
The deficiency of pantothenic acid is rare, since it is widespread in food. However, deficiency can occur in people with severe malnutrition or certain medical conditions. Symptoms of pantothenic acid deficiency may include fatigue, headaches, insomnia and hair loss. Sources of pantothenic acid include meat, fish, poultry, eggs, dairy products, vegetables and fruits.
VI. Pyridoxine (vitamin B6): SELECE STELS and scalp health
Pyridoxine, or vitamin B6, is an important coherent in many metabolic processes, including amino acid metabolism, neurotransmitter synthesis and hemoglobin formation. The effect of pyridoxine on hair growth is due to its role in the synthesis of protein and maintaining the health of the scalp.
Proteins are the main building blocks of hair. Pyridoxine is involved in amino acid metabolism, which are components of proteins. It is also necessary for the synthesis of keratin, the main protein that makes up the structure of the hair. The disadvantage of pyridoxine can lead to a decrease in keratin synthesis, which leads to a weakening of hair and slowing down hair growth.
Pyridoxine is also important for maintaining the health of the scalp. It helps to control the production of skin fat, an oily substance that moisturizes the skin and hair. The disadvantage of pyridoxine can lead to excessive production of sebum, which can lead to blockage of hair follicles and the development of seborrheic dermatitis, a condition characterized by itching, peeling and inflammation of the scalp. Seborrheic dermatitis can negatively affect hair growth.
A deficiency of pyridoxine can lead to various symptoms, including depression, irritability, fatigue and hair loss. Sources of pyridoxine include meat, fish, poultry, legumes, nuts, seeds and enriched cereals. Some drugs, such as oral contraceptives, can reduce the level of pyridoxine in the body.
VII. Biotin (Vitamin B7): Keratin and Volos Structure
Biotin, or vitamin B7, is often called “beauty vitamin” because of its role in maintaining the health of hair, skin and nails. It is a coherent in several important metabolic processes, including metabolism of fatty acids, carbohydrates and amino acids. The influence of biotin on hair growth is due to his participation in the synthesis of keratin.
Keratin is the main protein that makes up the structure of the hair. Biotin is necessary for the synthesis of keratin and plays an important role in maintaining health and strength of hair. It helps to strengthen the structure of the hair, preventing brittleness and split ends. The disadvantage of biotin can lead to a weakening of hair, thinning of hair and hair loss.
Although a biotin deficiency is relatively rare, it can occur in people with certain medical conditions, such as a disorder of biotinidase, a genetic disease that prevents the absorption of biotin. Biotin’s deficiency can also occur in people who consume a large number of raw eggs, since raw eggs contain avidine, protein that binds biotin and prevents its absorption.
Symptoms of biotin deficiency may include thinning of hair, fragility of nails, skin rash and neurological problems. Sources of biotin include meat, fish, eggs, dairy products, nuts, seeds and vegetables. Biotin is also produced by bacteria in the intestines. Biotin additives are widely available and are often used to improve the health of hair, skin and nails. However, it is important to note that studies on the effectiveness of biotin additives for hair growth are ambiguous.
VIII. Folic acid (vitamin B9): cell division and hair growth
Folic acid, or vitamin B9, plays a critical role in the division and growth of cells. It is necessary for the synthesis of DNA and RNA, genetic material, which carries information for all cellular processes. The effect of folic acid on hair growth is due to its participation in these processes.
Hair follicles are rapidly dividing cells that require a constant inflow of DNA and RNA to maintain hair growth. Folic acid provides the necessary building blocks for the synthesis of DNA and RNA, contributing to the normal division and growth of cells of hair follicles. The disadvantage of folic acid can slow down the division of cells of hair follicles, which leads to a slowdown in hair growth and thinning of the hair.
Folic acid is also important for transporting oxygen to hair follicles. It is involved in the formation of red blood cells that carry oxygen throughout the body. The disadvantage of folic acid can lead to anemia, a state characterized by a decrease in the number of red blood cells. Anemia can lead to insufficient supply of oxygen of hair follicles, which can lead to hair loss.
Folic acid deficiency can lead to various symptoms, including fatigue, weakness, irritability and hair loss. Sources of folic acid include green leafy vegetables, legumes, citrus fruits and enriched cereals. Pregnant women are recommended to take folic acid supplements to prevent defects in the nerve tube in the fetus.
IX. Cobalamin (vitamin B12): oxygen and health of hair follicles
Cobalamine, or vitamin B12, is necessary for the normal functioning of the nervous system and the formation of red blood cells. The effect of cobalamine on hair growth is due to its role in the transfer of oxygen to hair follicles.
Cobalamin is involved in the synthesis of DNA and RNA, as well as in the metabolism of amino acids and fatty acids. It is also necessary for the formation of myelin, the protective shell of nerve fibers. The disadvantage of cobalamin can lead to nerves damage and neurological problems.
Cobalamin plays an important role in the formation of red blood cells. Red blood cells tolerate oxygen throughout the body, including hair follicles. The disadvantage of cobalamin can lead to pernicious anemia, a state characterized by a decrease in the number of red blood cells due to a violation of cobalamin absorption. Pernicious anemia can lead to insufficient supply of oxygen of hair follicles, which can lead to hair loss.
Cobalamine deficiency can lead to various symptoms, including fatigue, weakness, numbness and tingling in the arms and legs, as well as hair loss. Sources of cobalamine include meat, fish, poultry, eggs and dairy products. Vegans and vegetarians are recommended to take cobalamine additives, as it is not found in plant products. The absorption of cobalamin requires the presence of an internal factor, protein produced by the stomach cells. Some people do not produce a sufficient amount of internal factor, which can lead to a deficiency of cobalamin, even with sufficient consumption of vitamin.
X. The role of group B vitamins in the treatment of alopecia and hair loss
B vitamins are often considered as a potential for the treatment of various forms of alopecia and hair loss. Although the deficiency of group B vitamins can contribute to hair loss, it is important to note that not all cases of hair loss are associated with a deficiency of vitamins.
In case of deficiency of group B vitamins, additives can help restore normal hair growth. However, in cases of hair loss caused by other factors, such as genetics, hormonal changes or autoimmune diseases, group B vitamins may not be effective.
Some studies have shown that biotin can be useful for the treatment of thinning of hair and fragility of nails. However, most studies were conducted in public with a deficiency of biotin, and the results are not necessarily applicable to people with a normal level of biotin.
Niacin can be useful for improving blood circulation in the scalp, which can stimulate hair growth. However, additional studies are needed to confirm this benefit.
In general, it is important to consult a doctor or a trichologist to determine the cause of hair loss and develop a suitable treatment plan. B vitamins can be a useful addition to the treatment plan, but they should not be considered the only remedy.
XI. Diet and additives: how to ensure sufficient consumption of B vitamins
The best way to provide sufficient consumption of B vitamins is to adhere to a variety of and balanced diet, rich in whole products.
Products rich in group B vitamins include:
- Meat (especially the liver)
- Fish
- Bird
- Eggs
- Dairy products
- Whole grain products
- Legumes
- Nuts
- Seeds
- Green sheet vegetables
- Fruits
In some cases, it may be necessary to take the additives of B vitamins, especially for people with a deficiency of vitamins, vegan and vegetarians, as well as for people with certain medical conditions that violate the absorption of nutrients.
When choosing the additive of B vitamins, it is important to choose a quality product from a reliable manufacturer. It is also important to follow the dosage instructions and not exceed the recommended dose. Reception of too much vitamins of group B can lead to side effects.
XII. Myths and facts about group B vitamins and hair growth
There are many myths and facts about group B vitamins and hair growth.
- Myth: B vitamins are guaranteed to stimulate hair growth for everyone.
- Fact: B vitamins can contribute to hair growth only if a person has a deficiency of these vitamins.
- Myth: Reception of a large amount of B vitamins will lead to a faster hair growth.
- Fact: Reception of too much vitamins of group B can be harmful and will not necessarily lead to a faster hair growth.
- Myth: Biotin is a miraculous hair growth.
- Fact: Biotin can be useful for the treatment of thinning of hair and fragility of nails, but it is not a miraculous tool for hair growth.
XIII. Conclusion: B vitamins as part of an integrated approach to hair health
B vitamins play an important role in maintaining hair health. They are necessary for energy metabolism, protein synthesis, the formation of red blood cells and maintaining the health of the scalp. B vitamins deficiency can lead to hair loss.
However, it is important to remember that group B vitamins are only one part of a comprehensive approach to hair health. Other factors, such as genetics, hormonal changes, stress and diet, also play an important role.
To maintain hair health, it is important to adhere to a diverse and balanced diet rich in vitamins and minerals, avoid stress, use high -quality hair care products and consult a doctor or a trichologist if problems with hair occur.
