Dietary supplements for hair strengthening: which actually work

Dietary supplements for hair strengthening: which actually work

Part 1: Introduction to the world of hair additives

Healthy, thick and shiny hair is a dream of many. Unfortunately, a modern lifestyle, stress, improper nutrition and aggressive environmental impact can adversely affect the state of hair. Hair becomes thin, brittle, dull, falls out. In such cases, many turn to bioactive additives (dietary supplements) for hair, hoping to strengthen them from the inside. But what additives are really effective, and which – only a marketing move? In this article, we will analyze in detail the most popular and scientifically sound dietary supplements to strengthen hair, their composition, mechanism of action, effectiveness, possible side effects and contraindications. We will also discuss the factors affecting the health of the hair, the importance of an integrated approach and warnings when choosing additives. Our goal is to provide you with complete and objective information so that you can make a conscious choice and improve your hair.

Part 2: Factors affecting hair health

Before considering specific additives, it is important to understand that hair health is a comprehensive process that depends on many factors. Ignoring these factors will reduce the effectiveness of any additive.

• Genetics: A genetic predisposition plays a key role in the structure, density and tendency to loss of hair. Some people are genetically predisposed to androgenetic alopecia (baldness by male type) or have thinner and more weak hair. Although genetics cannot be changed, its influence can be softened through proper care and nutrition.

• Nutrition: Hair, like any other organ, needs enough nutrients for normal growth and functioning. The deficiency of vitamins, minerals and proteins can lead to loss, thinning and dullness of hair. Key nutrients for hair health are:

  • Protein: The main building material of the hair (keratin). The lack of protein in the diet can lead to a slowdown in growth and thinning of the hair.
  • Iron: Participates in the transfer of oxygen to hair follicles. Iron deficiency (iron deficiency anemia) is one of the most common causes of hair loss, especially in women.
  • Zinc: It is necessary for cell growth and tissue restoration, including hair follicles. Zinc deficiency can lead to hair loss, dry scalp and dandruff.
  • Vitamin D: Plays an important role in the regulation of hair growth. The low level of vitamin D can be associated with hair loss.
  • B vitamins (biotin, niacin, pantotenic acid): Participate in the metabolism of energy and cell growth. Biotin is especially important for the health of hair and skin.
  • Vitamin C: Antioxidant, protects hair follicles from damage to free radicals. It is also necessary for the synthesis of collagen important for the structure of the hair.
  • Vitamin E: Antioxidant improves blood circulation in the scalp and promotes hair growth.
  • Omega-3 fatty acids: Reduce inflammation and improve the condition of the scalp.

• Hormonal balance: Hormonal changes, such as pregnancy, childbirth, menopause, thyroid diseases and polycystic ovary syndrome (SPKU), can have a significant effect on hair growth and loss. For example, an increased level of digidrotestosterone (DGT) is associated with androgenetic alopecia.

• Stress: Chronic stress can lead to hebogene falling (Telogen Effluvium), when a large number of hair follicles prematurely go into the rest phase and fall out.

• Diseases and medicines: Some diseases (for example, autoimmune diseases, scalp infections) and drugs (for example, chemotherapy, antidepressants, anticoagulants) can cause hair loss.

• Hair care: Aggressive styling methods (for example, frequent use of a hairdryer, curling iron, iron), dyeing, chemical curls and tight hairstyles can damage the hair and lead to its brittleness and loss.

• Age: With age, hair growth slows down, hair becomes thinner and more prone to loss.

Part 3: Key ingredients in hair dietary supplements: Scientific review

Let’s look at the most common and studied ingredients in hair dietary supplements and evaluate their effectiveness based on scientific data.

• Biotin (Vitamin B7 or Vitamin H):

  • Role: Biotin is necessary for the metabolism of carbohydrates, fats and proteins. It plays an important role in the synthesis of keratin, the main protein that makes up hair, skin and nails.
  • Efficiency: Biotin deficiency is a rare occurrence, but it can lead to hair loss, fragility of nails and skin problems. Studies show that biotin supplements can be effective for people with a Biotin deficiency. However, for people without deficiency, evidence of the effectiveness of biotin to strengthen hair is limited.
  • Cautions: High doses of biotin can distort the results of some laboratory tests, for example, tests for thyroid hormones. It is important to inform the doctor about taking biotin before taking tests.
  • Recommended dose: Doses of biotin in dietary supplements vary from 30 μg to 10 mg. The optimal dose depends on individual needs and the presence of deficiency.

• Collagen:

  • Role: Collagen is a structural protein that forms the basis of the skin, hair and nails. It provides elasticity and tissue strength.
  • Efficiency: With age, the production of collagen in the body decreases. Reception of collagen additives can stimulate the production of collagen in the skin and hair follicles, which can improve the condition of the hair, make them thicker and more shiny. Some studies show that collagen can also reduce hair loss. However, additional studies are needed to confirm these results.
  • Types of collagen: There are various types of collagen. For hair health, the most useful collagen type I and III. Hydrolyzed collagen (collagen peptides) is easier to absorb by the body.
  • Recommended dose: The doses of collagen in dietary supplements are usually from 2.5 to 10 grams per day.

• Vitamin D:

  • Role: Vitamin D plays an important role in the regulation of cell growth, including hair follicles. It also participates in the immune function and reduces inflammation.
  • Efficiency: Vitamin D deficiency is associated with various forms of hair loss, including focal alopecia (Alopecia Areata). Reception of vitamin D additives can be effective for people with vitamin D deficiency and hair loss. However, it is important to note that taking vitamin D without deficiency can be ineffective and even harmful.
  • Cautions: An overdose of vitamin D can lead to hypercalcemia (an increased level of calcium in the blood) and other health problems. It is important to take a blood test to the level of vitamin D before taking the additives and consult a doctor to determine the optimal dose.
  • Recommended dose: The recommended daily dose of vitamin D for adults is 600-800 IU. Doses in dietary supplements can vary, depending on the content of vitamin D.

• Iron:

  • Role: Iron is necessary for transferring oxygen to cells, including hair follicles. Iron deficiency can lead to iron deficiency anemia, which is one of the most common causes of hair loss, especially in women.
  • Efficiency: Taking iron additives can be effective for people with iron deficiency anemia and hair loss. However, the use of iron without deficiency can be harmful and lead to overloading with iron (hemochromatosis).
  • Cautions: Reception of iron additives can cause constipation, nausea and other gastrointestinal disorders. It is important to take iron with food and consume a sufficient amount of fiber to prevent constipation. It is not recommended to take iron simultaneously with calcium, since calcium can reduce iron absorption.
  • Recommended dose: The recommended daily dose of iron for women is 18 mg, for men – 8 mg. Doses in dietary supplements can vary, depending on the shape of iron.

• Zinc:

  • Role: Zinc is necessary for cell growth, tissue restoration and immune function. It also participates in the synthesis of protein and DNA.
  • Efficiency: Zinc deficiency can lead to hair loss, dry scalp and dandruff. Taking zinc additives can be effective for people with zinc deficiency and hair loss. However, the use of zinc without deficiency can be ineffective and even harmful.
  • Cautions: Taking high doses of zinc can lead to nausea, vomiting, diarrhea and a decrease in immunity. He can also prevent the assimilation of copper. Therefore, with prolonged use of zinc, it is recommended to take copper additives.
  • Recommended dose: The recommended daily zinc dose for women is 8 mg, for men – 11 mg. Doses in dietary supplements can vary.

• Vitamin C:

  • Role: Vitamin C is a powerful antioxidant, protects hair follicles from damage to free radicals. It is also necessary for the synthesis of collagen important for the structure of the hair.
  • Efficiency: Vitamin C can improve the absorption of iron, which indirectly affects the health of the hair. However, there is no direct evidence that the intake of vitamin C separately improves hair growth.
  • Recommended dose: The recommended daily dose of vitamin C for adults is 75-90 mg. Doses in dietary supplements can be higher.

• Vitamin E:

  • Role: Vitamin E is an antioxidant, improves blood circulation in the scalp and promotes hair growth.
  • Efficiency: Some studies show that vitamin E can improve the condition of the hair and reduce loss. However, additional studies are needed to confirm these results.
  • Recommended dose: The recommended daily dose of vitamin E for adults is 15 mg. Doses in dietary supplements can be higher.

• Omega-3 fatty acids:

  • Role: Omega-3 fatty acids reduce inflammation and improve the condition of the scalp. They also contribute to the moisturizing of the hair and give them shine.
  • Efficiency: Some studies show that taking the supplements of omega-3 fatty acids can improve the condition of the hair and reduce loss.
  • Sources: Omega-3 fatty acids are found in fish, linen seed, chia and walnuts. Bades with omega-3 fatty acids usually contain fish oil or krill oil.
  • Recommended dose: The recommended dose of omega-3 fatty acids varies, but usually 1-2 grams per day.

• Amino acids (L-cysteine, L-lisine, L-metionine):

  • Role: Amino acids – Building blocks of protein. L-cysteine, L-lysine and L-metionine are important components of keratin, the main protein that makes up the hair.
  • Efficiency: Reception of amino acid additives can improve the structure of the hair, make it more durable and shiny.
  • Recommended dose: Doses of amino acids in dietary supplements vary.

• Extracts of plants (horsetail extract, palm extract, green tea extract):

  • Horsetail extract: Contains silicon, which helps to strengthen hair and improve their structure.
  • Serene palm extract: Blocks the action of digidrotestosterone (DGT), a hormone associated with androgenetic alopecia.
  • Green tea extract: Contains antioxidants that protect hair follicles from damage.
  • Efficiency: The effectiveness of plant extracts to strengthen hair requires further study. Some studies show that they can be useful, but larger and well -planned clinical trials are needed.
  • Cautions: Plant extracts can interact with some drugs. It is important to consult a doctor before taking additives with plant extracts.
