1. Understanding the role of dietary supplements in hair health:
1.1 What are dietary supplements and how do they differ from drugs?
Dietary supplements (biologically active additives) are concentrates of natural or identical to natural biologically active substances designed for direct intake or introduction into food products in order to enrich the rations with individual food or biologically active substances and their complexes. Unlike drugs, dietary supplements are not intended for the treatment of diseases. They are used to maintain health, prevent nutrient deficiency and improve the functional state of the body.
The main difference between dietary supplements and drugs is as follows:
- Purpose of application: Medicines are designed for the treatment, diagnosis or prevention of diseases. Bades – to maintain health and replenish the deficiency of nutrients.
- Registration process: Medicines are held strict clinical trials and registration that requires evidence of effectiveness and safety. Bades undergo a less strict registration process, and evidence of their effectiveness is not always required.
- Normative regulation: The circulation of drugs is strictly regulated. The regulation of dietary supplements is less rigid.
- Concentration of active substances: In drugs, the concentration of active substances is clearly defined and controlled. In dietary supplements, concentration can vary.
- Effect on the body: Medicines have a therapeutic effect on the body. Bades have a general strengthening and preventive effects.
1.2 mechanisms for the action of hair dietary supplements.
Hair dietary supplements act comprehensively, acting on various aspects of the health of hair follicles and scalp. The main action mechanisms include:
- Filling a deficiency of nutrients: Bades contain vitamins, minerals, amino acids and other substances necessary for the normal growth and functioning of the hair. The deficiency of these substances can lead to loss, brittleness and dullness of hair.
- Improving blood circulation of the scalp: Some dietary supplements, such as niacin (vitamin B3) and red pepper extract, improve blood microcirculation in the scalp, providing oxygen and nutrients to hair follicles.
- Strengthening the structure of the hair: Amino acids, such as L-cysteine and L-Lisin, are construction blocks for keratin-the main protein of which the hair consists of. The dietary supplements containing these amino acids help strengthen the hair structure and make them more resistant to damage.
- Antioxidant Protection: Vitamins C and E, as well as selenium, are antioxidants that protect hair follicles from damage to free radicals.
- Hormonal balance regulation: Some plant extracts, such as cutting palm extract, can affect the hormonal balance and reduce hair loss associated with hormonal disorders.
- Hair growth stimulation: Some ingredients, such as biotin and zinc, stimulate cell division in hair follicles and accelerate hair growth.
- Improving the condition of the scalp: Omega-3 fatty acids and other substances contained in dietary supplements moisturize the scalp, reduce inflammation and itching, and contribute to a healthy hair growth.
1.3 The need to consult a doctor before starting dietary supplements.
Despite the fact that dietary supplements are not medicines, before the start of their administration, it is necessary to consult a doctor. This is due to several factors:
- Individual characteristics of the body: Each person has its own characteristics of metabolism, hormonal background and general health. Bad, which suits one person, can be ineffective or even harmful to another.
- Possible contraindications: Bades have contraindications that need to be taken into account. For example, some dietary supplements are not recommended for pregnant and nursing women, people with thyroid diseases, liver or kidneys.
- Interaction with drugs: Bades can interact with drugs, enhancing or weakening their effect. This can lead to undesirable side effects.
- Diagnosis of the causes of hair loss: Hair loss can be caused by various causes, including nutrient deficiency, hormonal disorders, stress, scalp diseases and other factors. The doctor will help to establish the cause of hair loss and choose the most effective treatment, which can include not only dietary supplements, but also other methods.
- The right choice of dietary supplement: A huge number of hair dietary supplements are presented on the market. The doctor will help choose a dietary supplement that contains the necessary ingredients in the optimal dosage and meets your individual needs.
- Efficiency and safety control: The doctor will control the effectiveness and safety of dietary supplements and, if necessary, adjust the dosage or replace dietary supplements with another.
2. Key ingredients in hair dietary supplements and their action:
2.1 B vitamins B (B7 – BIOTIN, B3 – NiaCin, B5 – Pantotenic acid, B12, Folic acid): functions and sources.
B vitamins play an important role in the health of the hair, participating in metabolic processes and providing the nutrition of hair follicles.
- Vitamin B7 (Biotin): One of the most famous hair vitamins. It is involved in the metabolism of fats, proteins and carbohydrates necessary for hair growth. Biotin strengthens the structure of the hair, prevents brittleness and loss. Biotin deficiency can lead to thinning of hair and dermatitis. Sources of biotin: eggs, liver, nuts, seeds, avocados, mushrooms.
- Vitamin B3 (Niacin): Improves blood circulation in the scalp, providing oxygen and nutrients to hair follicles. Niacin is also involved in the synthesis of keratin, the main protein of which the hair consists of. Niacin deficiency can lead to hair loss and dermatitis. Sources of Niacin: meat, fish, poultry, nuts, seeds, mushrooms.
