Section 1: Understanding the biology of hair growth and factors affecting their condition

1.1. Hair growth cycle: from anagen to heterogene

Hair life is a cyclic process consisting of several phases. Understanding these phases is critical of realizing how dietary supplements can affect the growth and health of the hair.

  • Anagen (growth phase): The longest phase lasts from 2 to 7 years (an average of 3-5 years). At this time, an active division of the cells of the hair follicle occurs, as a result of which the hair grows in length. The duration of the anagen determines the maximum length that the hair can reach. Genetic factors play a key role in determining the duration of this phase. Throughout the anagen, the hair follicle is deeply rooted in the dermis and is actively supplied with blood and nutrients.
  • Katagen (recression phase): The transition phase lasting about 2-3 weeks. Hair growth slows down, and the follicle begins to contract and separate from the papilla (Dermal Papilla), which supplies it with nutrients. Cell division stops, and the follicle begins to move to the surface of the skin. In this phase, the production of melanin, which is responsible for hair color, stops.
  • Telogen (Phase Salm): The resting phase lasts about 3 months. The hair completely stops growing and remains in the follicle in the form of a “glomerulus”. The papilla is completely separated from the follicle. About 10-15% of the hair on the head are in this phase at any time.
  • Exogen (falling phase): It is often considered as part of the heterogene, but is actually a phase when the hair falls out of the follicle. The new hair, located in the anagen phase, pushes the old hair. Daily loss of 50-100 hair is considered the norm.

1.2. Factors affecting health and hair growth

Many factors, both internal and external, can affect the hair growth cycle, their density, strength and general condition. Some of the most important factors include:

  • Genetics: The genetic predisposition plays a decisive role in determining the type of hair (thin, thick, straight, curly), the duration of the anagen phase, as well as a tendency to baldness (androgenetic alopecia). Heredity from both parents can affect the structure of the hair.
  • Hormonal balance: Hormones, especially androgens (testosterone, dihydrotestosterone – DGT), estrogens and thyroid hormones, have a significant effect on hair growth. The imbalance of hormones, for example, an increased level of DGT, can lead to miniaturization of hair follicles and hair loss, especially in men. In women, hormonal changes during pregnancy, after childbirth or during menopause, can also affect the condition of the hair.
  • Nutrition: Hair needs enough nutrients for healthy growth. The deficiency of proteins, vitamins (especially vitamins of group B, vitamin D, vitamin E), minerals (iron, zinc, selenium) and essential fatty acids can lead to a slowdown in hair growth, their thinning and loss.
  • Age: With age, the hair growth cycle slows down, the anagen phase is reduced, and the heterogene phase increases. This leads to a decrease in hair density and an increase in the number of hair dropping hair. Hair follicles can also decrease in size and produce thinner hair.
  • Stress: Chronic stress can negatively affect hair growth, causing heterogeneous loss (Telogen Effluvium) – a temporary loss of a large amount of hair located in the heterogene phase. Stress can affect the hormonal balance and worsen the absorption of nutrients.
  • Medical conditions: Some diseases, such as autoimmune diseases (for example, an area of ​​the area), thyroid disease, anemia, ovarian polycystic ovarian (PCO) and skin diseases (for example, seborrheic dermatitis), can cause hair loss. Some drugs (for example, chemotherapy, antidepressants, anticoagulants) can also have side effects that affect the condition of the hair.
  • Hair care: Aggressive methods of hair care, such as frequent dyeing, lightening, chemical curls, the use of hot tools (hair dryer, iron, curling hairstyles, can damage the hair and lead to their fragility and loss.
  • Environment: Air pollution, exposure to ultraviolet rays and chlorine water can also negatively affect hair health.

Section 2: The main ingredients in dietary supplements for hair growth and their action mechanisms

2.1. Vitamins

  • Vitamin A (Retinol): It is necessary for the growth and differentiation of cells, including the cells of the hair follicle. Participates in the synthesis of sebum, which moisturizes the scalp and hair. Vitamin A deficiency can lead to dry scalp and brittle hair. However, excess vitamin and can also be harmful and lead to hair loss. Bades usually contain beta-carotene, the predecessor of vitamin A, which is converted into vitamin A in the body, depending on the needs.
  • B vitamins B: Key to the health of hair.
    • Vitamin B1 (TIAMIN): Participates in the metabolism of carbohydrates, providing the energy of the cell of the hair follicle.
    • Vitamin B2 (Riboflavin): It is necessary for cellular respiration and growth.
    • Vitamin B3 (Niacin): Improves blood circulation in the scalp, contributing to the delivery of nutrients to hair follicles.
    • Vitamin B5 (pantotenic acid): Participates in the synthesis of Coenzyme A, which is necessary for the metabolism of fats and carbohydrates. Helps maintained hair moisturizes.
    • Vitamin B6 (Pyridoxin): Participates in the metabolism of proteins necessary for hair growth. Helps to absorb zinc, an important mineral for hair health.
    • Vitamin B7 (Biotin): One of the most famous vitamins for hair health. Participates in the synthesis of keratin, the main protein of which the hair consists of. Biotin deficiency can lead to hair loss, fragility of nails and skin problems. However, it is important to note that the biotin deficiency is relatively rare, and additives with biotin can be useful only in cases of proven deficiency. Reception of high doses of biotin can distort the results of some laboratory tests, for example, tests for thyroid hormones.
    • Vitamin B9 (folic acid): It is necessary for dividing cells and tissue growth, including hair follicles.
    • Vitamin B12 (cobalamin): Participates in the formation of red blood cells, which deliver oxygen to hair follicles. Vitamin B12 deficiency can lead to anemia and hair loss. It is especially important for vegetarians and vegans, since vitamin B12 is contained mainly in animal products.
  • Vitamin C (ascorbic acid): An antioxidant that protects the hair follicles from damage by free radicals. Participates in the synthesis of collagen, an important component of hair structure. Improves the absorption of iron.
  • Vitamin D: Plays an important role in the regulation of the hair growth cycle. Studies show that vitamin D deficiency can be associated with hair loss, especially with the alopecia of the area. Vitamin D stimulates the growth of new hair follicles and helps to maintain healthy immunity.
  • Vitamin E (tocopherol): An antioxidant that protects the cells from damage by free radicals. Improves blood circulation in the scalp, contributing to the delivery of nutrients to hair follicles. Helps maintained hair moisturizes.

2.2. Minerals

  • Iron: It is necessary for the formation of hemoglobin, which transfers oxygen to the cells of the body, including hair follicles. Iron deficiency (iron deficiency anemia) is one of the most common causes of hair loss, especially in women. It is important to note that an excess of iron can also be harmful, so before taking additives with iron, it is necessary to consult a doctor and take tests for the level of iron in the blood.
  • Zinc: Participates in the synthesis of proteins, including keratin, the main protein from which the hair consists of. It is necessary for the operation of the sebaceous glands that produce skin lard, moisturizing the scalp and hair. Zinc deficiency can lead to hair loss, slowing down, dry scalp and dandruff. Zinc also has antioxidant properties and protects the hair follicles from damage.
  • Selenium: An antioxidant that protects the cells from damage by free radicals. It is necessary for the normal function of the thyroid gland, which plays an important role in the regulation of hair growth. Selena deficiency can lead to hair loss and a change in their structure. However, the excess selenium can also be harmful and lead to hair loss.
  • Magnesium: Participates in many biochemical reactions in the body, including the synthesis of proteins and DNA. It helps to reduce stress, which can negatively affect hair growth. Magnesium deficiency can lead to hair loss.
  • Calcium: It is necessary for the growth and strengthening of hair. Participates in the regulation of hormonal balance. Calcium deficiency can lead to brittle hair and slowing down their growth.

2.3. Amino acids

  • L-Cistein: An amino acid containing sulfur, which is an important component of keratin, the main protein of which the hair consists of. L-cysteine ​​helps strengthen the hair, make it more elastic and resistant to damage.
  • L-Lisin: An indispensable amino acid that is involved in the synthesis of collagen and improves iron absorption. L-lyzine deficiency can lead to hair loss.
  • Methionine: An indispensable amino acid containing sulfur, which is involved in the synthesis of keratin. It has antioxidant properties and protects the hair follicles from damage.

2.4. Plant extracts

  • SAW Palmetto palm extract: It is used to treat androgenetic alopecia (male baldness). The enzyme 5-alpha reductase is blocking, which turns testosterone into dihydrotestosterone (DGT), a hormone that causes miniaturization of hair follicles and hair loss. The effectiveness of the Serenia palm in the treatment of hair loss is comparable to the effectiveness of finsteride (a drug used to treat androgenetic alopecia), but with fewer side effects.
  • Nettle extract: Contains vitamins, minerals and antioxidants that nourish hair follicles and improve blood circulation in the scalp. It has anti -inflammatory properties and helps reduce dandruff.
  • Horsetail extract: It is rich in silicon, which strengthens the hair and makes it more elastic. Improves blood circulation in the scalp.
  • Green tea extract: Contains antioxidants (catechins), which protect hair follicles from damage by free radicals. It can help reduce hair loss caused by stress.
  • The extract includes the wheelchair: Adaptogen, which helps the body adapt to stress. Reduces the level of cortisol, stress hormone, which can negatively affect hair growth.
  • Rosemary oil: Improves blood circulation in the scalp, stimulates hair growth and reduces hair loss. It has anti -inflammatory and antimicrobial properties. Studies show that rosemary oil can be as effective as minoxidil (a drug used to treat hair loss) in stimulating hair growth.

2.5. Other ingredients

  • Collagen: Protein, which is the main component of connective tissue, including skin, hair and nails. Collagen helps strengthen the hair, make it more elastic and resistant to damage. Reception of collagen can improve hydration of the scalp and reduce brittle hair. However, it is important to note that the collagen taken inside is broken down in the digestive tract into amino acids, which are then used by the body to synthesize its own proteins, including collagen. Therefore, the direct effect of collagen on the hair after oral administration has not been proven.
  • Keratin: The main protein from which the hair consists of. Keratin’s intake can help strengthen hair and make it more resistant to damage. However, as in the case of collagen, keratin, taken inside, is split into amino acids.
  • Hyaluronic acid: A moisturizing component that helps retain moisture in the scalp and hair. Improves hair elasticity and reduces their brittleness.

Section 4: How to choose the right dietary supplement for hair growth

4.1. Determining the cause of hair loss

Before you start taking any dietary supplements, it is important to determine the cause of hair loss. If hair loss is caused by a serious disease, hormonal imbalance or genetic factors, dietary supplements can be ineffective. In this case, you must consult a doctor for diagnosis and treatment. A trichologist or dermatologist can conduct a scalp examination, prescribe blood tests and other studies to determine the cause of hair loss and prescribe appropriate treatment.

4.2. Studying the composition of Bad

Carefully study the composition of the dietary supplement and make sure that it contains the ingredients that have proven their effectiveness in improving hair growth and health. Pay attention to the dosage of the ingredients and make sure that it corresponds to the recommended.

4.6. Reviews and ratings

Before buying dietary supplements, read the reviews of other customers and study the product ratings. Pay attention to the reviews that mention the effectiveness of the product, side effects and quality of customer service. Keep in mind that reviews can be subjective, and you should not rely only on them when making a decision.

4.7. Price

The price of dietary supplements for hair growth can vary greatly. Not always the most expensive supplement is the most effective. Compare prices for various dietary supplements and select the one that corresponds to your budget. Consider that in order to achieve visible results, it is necessary to take dietary supplements for several months, so it is necessary to take into account the total cost of the course of treatment.

4.8. Consultation with a specialist

The best way to choose the right dietary supplement for hair growth is to consult a doctor or a trichologist. A specialist can evaluate your health status, determine the cause of hair loss and give recommendations on the choice of a suitable dietary supplement. He can also control your condition during the admission of dietary supplements and adjust the dosage if necessary.

Section 5: Alternative methods for improving hair growth

5.1. Proper nutrition

A balanced diet, rich in proteins, vitamins, minerals and indispensable fatty acids, is the basis of healthy hair. Turn on in your diet products rich in iron (red meat, liver, legumes, spinach), zinc (seafood, nuts, seeds, meat), biotin (eggs, nuts, seeds, liver), vitamin D (fish, eggs, mushrooms) and omega-3 fatty acids (oily fish, linen seeds, walnuts). Limit the consumption of processed products, sugar and trans fats, which can negatively affect hair health.

5.2. Correct hair care

Use soft shampoo and air conditioning that do not contain aggressive sulfates and parabens. Avoid frequent hair wash, especially if you have dry scalp. Do not comb wet hair, as it is more vulnerable to damage. Use a comb with wide teeth. Limit the use of hot hair styling, such as a hair dryer, iron and curling iron. If you use hot tools, use thermal protection products. Avoid tight hairstyles that can stretch the hair and lead to its loss.

5.3. Scalp massage

Regular scalp massage improves blood circulation and stimulates hair growth. Massage can be done with hands or using special massager. Add a few drops of essential oil (for example, rosemary, lavender or cedar) to the base oil (for example, coconut, olive or jojoba) to enhance the effect.

5.4. Reducing stress levels

Chronic stress can negatively affect hair growth. Find the ways to reduce stress, such as yoga, meditation, walking in nature or communication with close people. Regular sleep and sufficient rest are also important for hair health.

5.5. Medicines

Minoxidil and finsteride are drugs that have proven their effectiveness in the treatment of androgenetic alopecia. Minoxidil is a solution that is applied to the scalp and stimulates hair growth. Finasteride is tablets that block the 5-alpha reductase enzyme that turns testosterone into dihydrotestosterone (DGT). Both drugs have side effects, so before their use it is necessary to consult a doctor.

5.6. Laser therapy

Low -level laser therapy (LLLT) is a non -invasive method for treating hair loss, which uses low intensity laser rays to stimulate hair growth. LLLT can improve blood circulation in the scalp, reduce inflammation and stimulate the growth of new hair follicles.

5.7. PRP therapy

PRP therapy (Platselet-Rich Plasma) is a method of treating hair loss that uses the patient’s own plasma, enriched with platelets, to stimulate hair growth. Plasma is inserted into the scalp with injection. Platelets contain growth factors that stimulate the growth of new hair follicles and improve blood circulation in the scalp.

5.8. Hair transplant

Hair transplant is a surgical method for treating hair loss in which hair follicles are transplanted from the donor zone (usually from the back of the head) to areas with hair loss. Hair transplant is an effective method of treating androgenetic alopecia, but it can be expensive and have risks associated with surgical intervention.
