Hair growth: myths and reality
I. Introduction: destroying hopes and exploring the facts about hair diets
Hair loss, their thinning and slow growth are problems that worry millions of people around the world. Advertising announcements about wonderful means promising thick hair in a short time were filled with the Internet and store shelves. Among these promises, a special place is occupied by biologically active additives (dietary supplements), positioned as a panacea from all troubles associated with hair. However, before rushing into the pool with your head and spending money on these often expensive products, you need to figure out what the hair growth is actually, what components are contained in them, and what confirms or refutes their effectiveness. This detailed analysis is designed to separate myths from reality, provide the reader with complete information about various ingredients, potential risks and side effects, and also help make a balanced decision based on scientific data and expert opinions.
II. What are dietary supplements and why are they so popular?
Bades (biologically active additives) are concentrates of natural or identical to natural biologically active substances, designed for direct consumption with food or introduction into food products. They are not drugs and, therefore, do not pass strict quality control and clinical trials necessary for drugs. The popularity of dietary supplements is due to several factors:
- Accessibility and convenience: Bad can easily be purchased in pharmacies, specialized stores and online, without a doctor’s prescription.
- Marketing promises: Aggressive advertising, often based on unverified statements, gives the impression of a quick and effective solution to hair problems.
- The idea of naturalness: Many consumers believe that dietary supplements, as products containing “natural” ingredients are safer than medicines.
- Dissatisfaction with traditional methods of treatment: People who have not received the desired results from traditional methods of treating hair loss often turn to dietary supplements in the hope of a miracle.
However, it is important to understand that the lack of strict regulatory requirements for dietary supplements creates risks associated with the quality of products, the inaccuracy of the declared properties and potential side effects.
III. The main ingredients of dietary supplements for hair growth and their alleged action
Bad for hair growth contain a wide range of ingredients, which, according to manufacturers, are able to stimulate hair growth, strengthen their structure and improve the overall condition of the scalp. Consider the most common of them:
- B vitamins B (Biotin, B5, B6, B12): Biotin (vitamin B7 or H) is one of the most popular hair dietary supplements. It is believed that it plays an important role in the metabolism of fats, carbohydrates and proteins necessary for hair growth. Vitamin B5 (pantothenic acid) is involved in the formation of coenzyme A, which is important for the health of the skin and hair. Vitamins B6 and B12 are also involved in metabolic processes and can affect the condition of the hair.
- Myths and reality: The deficiency of group B vitamins can lead to hair loss, however, if a person does not have a deficiency, additional intake of these vitamins is unlikely to have a significant effect on hair growth. Clinical studies on the effectiveness of biotin for hair growth in people without biotin deficiency give conflicting results. Most studies confirming the effectiveness of biotin were conducted in public with a deficiency of this vitamin or with genetic diseases affecting biotin metabolism.
- Vitamin D: Vitamin D plays an important role in the regulation of cellular growth and differentiation, including hair follicles. Vitamin D deficiency is associated with various forms of hair loss, including focal alopecia.
- Myths and reality: The low level of vitamin D can really contribute to hair loss. However, if the level of vitamin D is normal, additional intake of additives is unlikely to significantly improve hair growth. Studies show that vitamin D additives can be useful for people with vitamin D deficiency and some forms of alopecia.
- Vitamin E: Vitamin E is a powerful antioxidant that protects the cells from damage by free radicals. It is believed that it improves blood circulation in the scalp and stimulates hair growth.
- Myths and reality: Although vitamin E is useful for health in general, its effect on hair growth has not been proven convincingly. Some small studies have shown that vitamin E can improve hair growth in people with alopecia, but additional studies are needed.
- Vitamin C: Vitamin C is necessary for the synthesis of collagen, which is an important structural component of hair. It is also an antioxidant and protects the hair from damage.
- Myths and reality: Vitamin C is important for hair health, but its effect on hair growth is limited. Vitamin C deficiency can lead to brittle hair, but additional intake of vitamin C is unlikely to significantly improve hair growth in people who receive a sufficient amount of vitamin C from food.
- Iron: Iron plays an important role in transporting oxygen to cells, including hair follicles. Iron deficiency is a common cause of hair loss, especially in women.
- Myths and reality: Iron deficiency can really lead to hair loss. In such cases, taking iron additives can be effective for restoring hair growth. However, it is important to determine the cause of iron deficiency and exclude other possible causes of hair loss. Reception of iron additives without need can be harmful to health.
- Zinc: Zinc is necessary for many enzymatic reactions in the body, including protein synthesis and cell division. Zinc deficiency can lead to hair loss.
- Myths and reality: Zinc deficiency can contribute to hair loss, and taking zinc additives can be effective in such cases. However, an excess of zinc can also be harmful and lead to other health problems.
- Selenium: Selenium is an antioxidant that protects the cells from damage. It is also necessary for the health of the thyroid gland, which plays an important role in the regulation of hair growth.
- Myths and reality: Selenium is important for hair health, but its effect on hair growth is limited. Selena deficiency can lead to hair loss, but sewing of selenium can also be toxic.
- Amino acids (L-cysteine, l lis, methionine): Amino acids are construction blocks of proteins, including keratin, the main protein that makes up the structure of the hair.
- Myths and reality: Amino acids are necessary for hair growth, but their deficiency is rare in people who receive a sufficient amount of protein with food. An additional intake of amino acids can be useful for people experiencing protein deficiency, but their effect on hair growth in people receiving a sufficient amount of protein has not been proven convincingly.
- Collagen: Collagen is the main structural protein in the skin, hair and nails. It is believed that taking collagen additives can improve skin elasticity, strengthen hair and stimulate their growth.
- Myths and reality: Collagen is indeed an important hair component, but there is no convincing evidence that taking collagen additives directly stimulates hair growth. Collagen entering the body with food or additives is split into amino acids, which are then used to synthesize proteins necessary for hair growth.
- Plant extracts (Saw Palmetto, Green Tea Extract, Horsetail Extract): Plant extracts contain various biologically active substances, which, according to manufacturers, can block DGT (digidrotestosterone), a hormone associated with hair loss, or stimulate blood circulation in the scalp.
- Myths and reality: The effectiveness of plant extracts for hair growth is not proven convincingly. Some studies have shown that Saw Palmetto can be useful for the treatment of androgenic alopecia, but additional studies are needed. Green Tea Extract contains antioxidants that can be useful for hair health, but its effect on hair growth is limited. Horsetail Extract contains silicon, which can strengthen hair, but its effect on hair growth is not proven convincingly.
IV. Scientific research and clinical trials: What does the science of the effectiveness of hair dietary supplements say?
Clinical trials devoted to the study of the effectiveness of dietary supplements for hair growth often have restrictions, including a small number of participants, the absence of control groups and the use of subjective assessment methods. Many studies are financed by dietary supplements, which can lead to a displacement of the results.
- Review of existing studies: The general conclusion from existing studies is that dietary supplements for hair growth can be effective only in cases of deficiency of certain nutrients. If a person does not have a deficiency of vitamins or minerals, additional intake of dietary supplements is unlikely to have a significant effect on hair growth.
- The importance of placebo-controlled research: Placebo-controlled research is the “gold standard” of clinical research. In these studies, one group of participants receives an active drug, and the other – a placebo (dummy). If the results in the group that received an active drug is much better than in the group that received placebo, this indicates the effectiveness of the drug. Unfortunately, placebo-controlled studies of dietary supplements for hair growth are not enough.
V. The risks and side effects of hair dietary
Despite the fact that dietary supplements are often positioned as safe products, they can cause side effects and interact with drugs.
- Allergic reactions: Many dietary supplements contain plant extracts that can cause allergic reactions in people with increased sensitivity.
- Interaction with drugs: Some dietary supplements can interact with drugs by changing their effectiveness or increasing side effects. For example, vitamin K can reduce the effectiveness of anticoagulants (drugs that thin blood).
- An overdose of vitamins and minerals: Reception of large doses of vitamins and minerals can be harmful to health. For example, an overdose of vitamin A can lead to hair loss, and an overdose of iron can cause liver damage.
- Poor products: Since dietary supplements do not undergo strict quality control, such as drugs, there is a risk of acquiring low -quality products containing harmful impurities or improper dosage of ingredients.
- Masks of serious diseases: Reception of dietary supplements can mask the symptoms of serious diseases, such as thyroid diseases or autoimmune diseases that can cause hair loss.
VI. Who should take dietary supplements for hair growth?
Hair growth can be useful in the following cases:
- Confirmed deficiency of vitamins and minerals: If blood tests show a deficiency of vitamins or minerals, the use of dietary supplements containing these nutrients can help restore their level and improve the condition of the hair.
- Certain diseases: Some diseases, such as focal alopecia, can be associated with a deficiency of certain nutrients. In such cases, the reception of dietary supplements prescribed by a doctor may be useful.
- Vegetarianism and veganism: Vegetarians and vegans can experience a deficiency of certain nutrients, such as vitamin B12, iron and zinc. In such cases, the reception of dietary supplements can help replenish this deficit.
VII. How to choose the right dietary supplement for hair growth?
If you decide to try a dietary supplement for hair growth, it is important to choose a quality product that will not harm your health.
- Consultation with a doctor: Before you start taking dietary supplements, consult a doctor to exclude possible contraindications and interactions with medicines. The doctor may also prescribe blood tests to determine the presence of a deficiency of vitamins and minerals.
- The choice of a reliable manufacturer: Choose dietary supplements from well -known and respected manufacturers who comply with quality standards and conduct laboratory research on their products.
- Checking the composition: Carefully study the composition of the dietary supplement and make sure that it contains the ingredients that have proven their effectiveness in clinical research.
- Avoid products with dubious ingredients: Avoid products containing ingredients that do not have a scientific justification or may be harmful to health.
- Follow the recommended dosage: Do not exceed the recommended dosage indicated on the packaging.
- Pay attention to the reviews: Read the reviews of other users about the product, but do not rely only on them.
VIII. Alternative methods for improving hair growth
There are alternative methods that can be more effective and safe to improve hair growth than to receive dietary supplements.
- Balanced nutrition: Make sure you get enough protein, vitamins and minerals with food.
- Correct hair care: Use soft shampoos and air conditioners, avoid frequent hair dryer and ironing, do not injure your hair with rough combing.
- Scalp massage: Regular scalp massage improves blood circulation and stimulates hair growth.
- Medication: In cases of serious hair loss, the doctor may prescribe drug treatment, such as minoxidil or finsteride.
- Professional procedures: There are professional procedures, such as mesotherapy and PRP therapy that can stimulate hair growth.
IX. Conclusion: accept or not take dietary supplements for hair growth?
The decision to take dietary supplement for hair growth should be based on individual needs, blood tests and consultation with a doctor. Bades can be useful in cases of confirmed deficiency of nutrients, but are not a miraculous tool that can solve all hair problems. It is important to remember the possible risks and side effects of dietary supplements and choose quality products from reliable manufacturers. Alternative methods, such as a balanced diet, proper hair care and scalp massage, can be more effective and safe to improve hair growth. In cases of serious hair loss, you must consult a doctor to diagnose and prescribe the appropriate treatment.
X. Review of specific dietary supplements and their components
Consider several specific examples of popular dietary supplements for hair growth and analyze the composition of their components:
- Perfectil: This dietary supplement contains a wide range of vitamins, minerals and plant extracts, including B vitamins, vitamin D, vitamin E, iron, zinc, selenium, amino acids and grape seed extract. Although many of these ingredients are important for hair health, there is no convincing evidence that Perfectil effectively stimulates hair growth in people without a deficiency of these nutrients.
- Hairfinity: Hairfinity contains biotin, vitamins of group B, vitamin C, vitamin D, amino acids and the patented mixture of Capilsana Complex. Capilsana Complex includes hydrolyzed collagen, MSM and horsetail extract. The effectiveness of Capilsana Complex for hair growth is not proven convincingly.
- Viviscal: Viviscal contains the Aminomar C complex, which is a patented mixture of sea extracts. Some studies have shown that Viviscal can improve hair growth in people with thinning of hair, but additional studies are needed.
XI. The effect of stress on hair health and the role of dietary supplements in the fight against stress
Stress is one of the main factors affecting hair health. Chronic stress can lead to hair loss, slowing hair growth and other hair problems. Some dietary supplements contain ingredients, which, according to manufacturers, help reduce stress, such as adaptogens (for example, Rodiola Pink, Ashvaganda) and magnesium. However, it is important to understand that dietary supplements are not a replacement for a healthy lifestyle and effective stress management strategies. Regular physical exercises, meditation, yoga and other relaxation techniques can be more effective for reducing stress and improving hair health.
XII. The relationship between the hormonal background and the growth of hair: can dietary beads help?
Hormonal background plays an important role in the regulation of hair growth. Hormonal disorders, such as the imbalance of thyroid hormones or an increased level of DHT, can lead to hair loss. Some dietary supplements contain ingredients that, according to manufacturers, help to balance hormonal background, such as Saw Palmetto and DIM (diisodolmetan). Saw Palmetto can block DGT, and DIM can contribute to the balance of estrogen. However, it is important to understand that hormonal disorders can be caused by serious diseases, and dietary supplements can be dangerous. If hormonal disorders are suspected, consult a doctor to diagnose and prescribe the appropriate treatment.
XIII. The role of nutrition in hair health: how to make a balanced diet for healthy hair
Food plays a key role in hair health. For healthy hair, it is necessary to obtain a sufficient amount of protein, vitamins, minerals and essential fatty acids.
- Protein: Protein is the main building material for hair. Good sources of protein include meat, fish, eggs, legumes and nuts.
- Vitamins: B vitamins B, vitamin D, vitamin E and vitamin C are necessary for hair health. A diverse diet that includes fruits, vegetables and whole grains can provide a sufficient amount of these vitamins.
- Minerals: Iron, zinc, selenium and magnesium are necessary for hair health. Good sources of these minerals include meat, fish, nuts, seeds and green leafy vegetables.
- INFORMATIONAL BYSTENT APLISTS: Omega-3 and omega-6 fatty acids are important for the health of the scalp and hair. Good sources of these fatty acids include fish, nuts, seeds and vegetable oils.
XIV. Microbia of the scalp and its effect on hair health: Can dietary supplements improve it?
A microbia of the scalp is a set of microorganisms that inhabit the scalp. The imbalance of the microbioma of the scalp can lead to various problems with hair, such as dandruff, itching and inflammation. Some dietary supplements contain probiotics and prebiotics, which, according to manufacturers, help improve the balance of the microbioma of the scalp. However, it should be noted that studies on the influence of probiotics and prebiotics on the microbia of the scalp and hair of the hair are limited.
XV. The latest developments and research in the field of dietary supplements for hair growth
Scientific research in the field of dietary supplements for hair growth continues. New studies study the effectiveness of various ingredients, such as peptides, growth factors and stem cells, to stimulate hair growth. However, most of these studies are in the early stages, and additional studies are needed to confirm the effectiveness of these new ingredients.
XVI. Legal aspects and regulation of the market for hair growth
The regulation of the market for hair growth is different in different countries. In some countries, dietary supplements are subject to more strict control than in others. It is important to know the legal aspects of the acquisition and use of dietary supplements in your country and choose products that meet quality and safety standards.
XVII. Hair growth in women: features and recommendations
Hair loss in women can be caused by various causes, including hormonal changes, stress, nutrient deficiency and thyroid disease. Hair growth, intended for women, often contain ingredients that help to balance hormonal background and make up for a nutrient deficiency. However, it is important to remember that before starting to receive dietary supplements, it is necessary to consult a doctor in order to exclude possible contraindications and interactions with drugs.
XVIII. Hair growth in men: features and recommendations
Hair loss in men is most often associated with androgenic alopecia (male baldness), which is caused by a genetic predisposition and an increased level of DGT. Hair growth, intended for men, often contain ingredients that block DGT, such as Saw Palmetto and zinc. However, it is important to understand that dietary supplements cannot completely stop androgenic alopecia, and in cases of serious hair loss, you must consult a doctor to prescribe drug treatment.
XIX. Hair growth after childbirth: what is safe and effective?
Hair loss after childbirth is a common problem that is caused by hormonal changes. Usually hair loss after childbirth ceases by itself after a few months. However, some women may experience more severe and prolonged hair loss. Bad for hair growth can be useful for restoring hair growth after childbirth, but it is important to choose safe products that do not contain ingredients contraindicated during breastfeeding. Consultation with a doctor before starting dietary supplements after childbirth is required.
XX. Bad for hair growth in old age: is it worth taking them?
With age, natural thinning of the hair and slowing down their growth occurs. Hair growth dietary supplements can be useful for maintaining hair health in old age, but it is important to consider possible contraindications and interactions with medicines. Reception of dietary supplements in old age should be agreed with a doctor.
XXI. Conclusion: summing up and recommendations for the choice and use of dietary supplements for hair growth.
In conclusion, dietary supplements for hair growth can be useful in certain cases, but are not a panacea. It is important to remember the possible risks and side effects of dietary supplements and choose quality products from reliable manufacturers.
