I. Introduction to the world of vitamins for hair growth
Hair is not just a jewelry, it is an important indicator of a general state of health. Their appearance, density and growth rate can tell a lot about the presence of nutrient deficits, hormonal failures or other problems in the body. Healthy, strong and brilliant hair is the result of an integrated approach, including a balanced diet, proper care and, if necessary, taking vitamins and minerals.
Vitamins and minerals play a key role in various processes occurring in the body, including in the process of growth and maintenance of hair health. They participate in the formation of keratin, the main building material of the hair, provide hair follicles with the necessary nutrients and protect them from damage.
However, it is important to understand that taking hair vitamins is not a panacea. They are effective only if the cause of hair problems is a deficiency of certain vitamins and minerals. The uncontrolled technique of vitamin complexes can not only not be beneficial, but also harm health.

Before starting taking vitamins and minerals to improve hair growth, it is important to make sure that their deficiency is in the body. An independent purpose of vitamin complexes can not only not bring the desired result, but also harm health.
A. General signs of deficiency of vitamins and minerals
There are a number of common features that may indicate a deficiency of vitamins and minerals in the body. These signs are not specific and can be caused by other reasons, but if any, it is recommended to consult a doctor for examination.
- Fatigue and weakness: The lack of iron, vitamin B12 or vitamin D can cause a feeling of constant fatigue and weakness.
- Hair loss: The deficiency of iron, zinc, biotin, vitamin D and other vitamins and minerals can lead to hair loss.
- Fitty nails: The disadvantage of biotin, iron, zinc and other vitamins and minerals can cause fragility and stratification of nails.
- Dry skin: The deficiency of vitamin A, vitamin E, zinc and other vitamins and minerals can lead to dryness and peeling of the skin.
- Digestive problems: The lack of vitamins of group B, magnesium and other vitamins and minerals can cause constipation, diarrhea and other digestive problems.
- Reduced immunity: The deficiency of vitamin C, vitamin D, zinc and other vitamins and minerals can reduce immunity and increase susceptibility to infections.
- Sleep problems: The disadvantage of magnesium, vitamin D and other vitamins and minerals can cause insomnia and other sleep problems.
B. Special blood tests: determining the level of vitamins and minerals
To accurately determine the level of vitamins and minerals in the body, it is necessary to pass a blood test. The doctor will prescribe the necessary tests depending on the symptoms and history of the patient.
- General blood test: Allows you to evaluate the general state of health and identify signs of anemia.
- Biochemical blood test: Allows you to evaluate the level of vitamins and minerals in the blood, such as vitamin D, vitamin B12, iron, zinc, magnesium and others.
- Blood test for thyroid hormones: It allows you to exclude thyroid diseases that can cause hair loss.
C. Trichoscopy and other methods of diagnosing the condition of the hair and scalp
Trichoscopy is a non -invasive diagnostic method that allows you to evaluate the condition of the hair and scalp using a special device – a trichoscope. Trichoscopy allows you to identify various problems, such as:
- Hair refinement: Trichoscopy allows you to evaluate the thickness of the hair and identify signs of thinning.
- Changing the structure of the hair: Trichoscopy allows you to detect damage to the structure of the hair, such as brittleness, section and dryness.
- Scalp diseases: Trichoscopy allows you to identify signs of inflammation, fungal infections and other diseases of the scalp.
In addition to trichoscopy, the doctor can prescribe other diagnostic methods, such as:
- Phototrichogramma: A method to assess the hair density and their growth rate.
- Scalp biopsy: In rare cases, a scalp biopsy may be required to diagnose complex diseases.
V. Contraindications to the reception of vitamins for hair: when you need to be careful
Despite the fact that vitamins are necessary for hair health, their reception has a number of contraindications in which caution must be observed or refrain from taking vitamin complexes.
A. Individual intolerance to the components of vitamin complexes
Individual intolerance to the components of vitamin complexes is one of the main contraindications to their reception. Allergic reactions can occur on any of the components that make up the vitamin complex, including vitamins themselves, minerals, auxiliary substances and dyes.
- Symptoms of an allergic reaction:
- Skin rash, itching, urticaria
- Quincke’s edema (facial edema, lips, tongue and larynx)
- Anaphylactic shock (severe allergic reaction requiring immediate medical care)
- If any signs of an allergic reaction appear, it is necessary to immediately stop taking the vitamin complex and consult a doctor.
- Before taking the vitamin complex, it is necessary to carefully familiarize yourself with its composition and make sure that there are no individual intolerance to the components.
B. Chronic diseases and taking drugs: interaction with vitamins
In the presence of chronic diseases and taking drugs, it is necessary to consult a doctor before taking hair vitamins, since vitamins can interact with drugs and influence the course of the disease.
1. Diseases of the liver and kidneys
For diseases of the liver and kidneys, metabolism and elimination of vitamins from the body are disturbed, which can lead to their accumulation and development of toxic effects.
- Vitamins that require special caution in diseases of the liver and kidneys:
- Vitamin a
- Vitamin D.
- B vitamins b
- For diseases of the liver and kidneys, it is necessary to consult a doctor to determine the optimal dosage of vitamins and the choice of a vitamin complex, which will not have a negative effect on the function of these organs.
2. Diseases of the gastrointestinal tract
For diseases of the gastrointestinal tract, the absorption of vitamins and minerals is disrupted, which can lead to their deficiency. However, taking vitamin complexes can aggravate the symptoms of the disease, such as nausea, vomiting and diarrhea.
- Vitamins that can irritate the gastrointestinal tract:
- Vitamin C.
- Iron
- Zinc
- For diseases of the gastrointestinal tract, you need to consult a doctor to select a vitamin complex, which will be well tolerated and will not cause side effects.
3. Diseases of the thyroid gland
Vitamins and minerals, such as selenium and iodine, play an important role in the function of the thyroid gland. However, with thyroid diseases, the intake of these vitamins and minerals can affect the hormonal balance and require the correction of the dosage of drugs.
- For diseases of the thyroid gland, it is necessary to consult an endocrinologist before taking vitamin complexes.
4. Autoimmune diseases
In autoimmune diseases, the body’s immune system attacks its own tissues, including hair follicles. The reception of some vitamins and minerals, such as vitamin D, can affect the immune system and require special attention.
- In autoimmune diseases, it is necessary to consult with an immunologist before taking vitamin complexes.
5. Taking anticoagulants, antibiotics and other drugs
Vitamins can interact with various drugs, changing their effectiveness and causing side effects.
- Anticoagulants: Vitamin E can enhance the effect of anticoagulants, increasing the risk of bleeding.
- Antibiotics: Some antibiotics can reduce the absorption of B vitamins B.
- Anticonvulsants: Some anticonvulsants can reduce the level of biotin in the body.
- Before taking vitamins for hair, it is necessary to inform the doctor about all the drugs taken.
C. Pregnancy and lactation: special recommendations for taking vitamins
During pregnancy and during lactation, the need for vitamins and minerals increases, but taking vitamin complexes requires special attention and consultation with a doctor.
- Vitamin A: High doses of vitamin A can cause congenital defects in the fetus.
- Folic acid: Folic acid is necessary for the normal development of the nervous system of the fetus and is recommended to take all pregnant women.
- Iron: The need for iron increases during pregnancy, and taking iron drugs may be necessary to prevent anemia.
- Vitamin D: Vitamin D is necessary for the normal development of the bones and teeth of the fetus.
- ** During lactation, vitamins and minerals enter breast milk, so
