Effective dietary supplements for hair density: the path to lush hair

Chapter 1: Understanding the hair and the reasons for their thinning

1.1 Anatomy and physiology of the hair:

Hair is a threaded keratin structure growing from a hair follicle located in the skin. It consists of three main layers:

Cuticle: The outer layer formed by overlapping cells resembling tiles. Protects the inner layers of the hair from damage and determines its gloss. The damaged cuticle leads to dim, brittle hair.
Cortical layer (bark): The thickest layer that makes up the bulk of the hair. Contains melanin, a pigment that determines the color of the hair, as well as keratin fibers that give the hair strength and elasticity.
Medulla: The most inner layer present in all hair. Its function has not been fully studied, but it is believed that it can affect the thickness and thermal insulation of the hair.

Hair follicle is a complex formation located in the dermis (a layer of skin under the epidermis). He is responsible for hair growth. Inside the follicle is a hair papilla containing blood vessels that feed the hair and provide its growth.

Hair growth occurs cyclically and consists of three main phases:

Anagen (growth phase): The longest phase lasts from 2 to 7 years. In this phase of the hair is actively growing. The duration of the anagen determines the length to which the hair can grow.
Katagen (transition phase): A short phase lasting about 2-3 weeks. In this phase, hair growth stops, and the hair follicle is reduced.
Telogen (Phase Salm): The phase lasting about 3 months. In this phase, the hair remains in the follicle, but does not grow. At the end of the heterogene, the hair falls out, and in its place the new hair in the anagen phase begins to grow.

Normally, on the human head, hair is simultaneously in all three phases of growth. About 85-90% of the hair are in the anagen phase, 1-2% in the Katagen phase, and 10-15% in the bodyogen phase.

1.2 Factors affecting the density of the hair:

Hair density is the amount of hair per square centimeter of the scalp. It depends on several factors, including:

Genetics: The genetic predisposition plays a key role in determining the density of the hair. Some people by nature have thicker hair than others.
Age: With age, the number of hair follicles may decrease, which leads to thinning of the hair.
Hormonal background: Hormonal changes, such as pregnancy, childbirth, menopause, as well as impaired thyroid function, can affect the height and density of the hair.
Nutrition: The lack of certain nutrients, such as protein, iron, zinc, vitamins of group B and vitamin D, can lead to thinning and hair loss.
Stress: Chronic stress can negatively affect hair growth and contribute to its loss.
Scalp diseases: Some diseases of the scalp, such as seborrheic dermatitis, psoriasis and fungal infections, can lead to inflammation and damage to the hair follicles, which prevents hair growth.
Medications: Some drugs, such as chemotherapeutic agents, antidepressants and drugs to reduce blood pressure, can cause hair loss.
Hair injuries: Excessive use of hot laying tools, chemical curls and dyeing can damage the hair and lead to their thinning.
External factors: The effects of ultraviolet radiation, environmental pollution and hard water can also negatively affect hair health.

1.3 Causes of thinning of hair:

The thinning of the hair, or alopecia, can be caused by various factors. The most common reasons include:

Androgenic alopecia (hereditary hair loss): The most common form of hair loss due to a genetic predisposition and the influence of hormones of androgens (male sex hormones). In men, it manifests itself in the form of a gradual retreat of the hair growth line and thinning of the hair on the crown. In women, it manifests itself in the form of diffuse thinning of hair throughout the head.
Telogen hair loss: Temporary hair loss caused by stress, illness, pregnancy, diet or medication. It is characterized by an increase in the amount of hair located in the heterogene phase.
Focal alopecia: Autoimmune disease in which the immune system attacks the hair follicles, which leads to hair loss in the form of separate foci.
Traction alopecia: Hair loss caused by constant hair tension, for example, when wearing tight hairstyles, such as braids or tails.
Rickeeper alopecia: Hair loss caused by damage to the hair follicles and the formation of cicatricial fabric. It can be caused by infections, burns, injuries or autoimmune diseases.

Chapter 2: Key Nutrients for Hair Health

2.1 protein (amino acids):

Hair consists mainly of keratin, fibrillar protein. Therefore, sufficient protein consumption is critical of hair health and their growth. The lack of protein can lead to thinning, brittleness and hair loss.

How works: The protein provides building blocks (amino acids) necessary for the synthesis of keratin.
Recommendations: An adult needs about 0.8 grams of protein per kilogram of body weight per day. With increased physical activity or the availability of hair problems, the need for protein can be increased.
Sources: Meat, fish, poultry, eggs, dairy products, legumes, nuts and seeds.

2.2 Iron:

Iron is necessary for transporting oxygen to hair follicles. Iron deficiency (iron deficiency anemia) is one of the common causes of hair loss, especially in women.

How works: Iron is part of hemoglobin, protein in red blood cells, which tolerates oxygen. The lack of iron leads to the insufficient intake of oxygen to hair follicles, which slows down their growth and can lead to hair loss.
Recommendations: The recommended daily dose of iron is 18 mg for women and 8 mg for men. Women during menstruation and pregnancy require more iron.
Sources: Red meat, liver, legumes, spinach, pumpkin seeds, iron enriched products. It is important to use iron with products containing vitamin C to improve its absorption.

2.3 zinc:

Zinc plays an important role in the growth and restoration of fabrics, including hair follicles. It is also necessary for the operation of the sebaceous glands that support the health of the scalp. Zinc deficiency can lead to hair loss, dry scalp and dandruff.

How works: Zinc is involved in the synthesis of the protein necessary for hair growth, as well as in the regulation of hormones that affect hair growth. It also has antioxidant properties, protecting the hair follicles from damage.
Recommendations: The recommended daily dose of zinc is 8 mg for women and 11 mg for men.
Sources: Oysters, red meat, poultry, nuts, seeds, legumes, whole grain products.

2.4 Biotin (Vitamin B7):

Biotin is a vitamin of group B, which plays an important role in the metabolism of fats, carbohydrates and proteins. It is also necessary for the health of the skin, hair and nails. Biotin deficiency is rare, but can lead to hair loss, fragility of nails and skin rashes.

How works: Biotin is involved in the synthesis of keratin, the main protein that makes up the hair. It also helps to improve hair structure and give it shine.
Recommendations: The recommended daily dose of biotin is 30 mcg.
Sources: Eggs, liver, nuts, seeds, avocados, cauliflower, mushrooms.

2.5 Vitamin D:

Vitamin D plays an important role in the regulation of hair growth. Studies have shown that vitamin D deficiency can be associated with hair loss, including focal alopecia.

How works: Vitamin D is involved in the regulation of cellular growth and differentiation. He can also play a role in activating hair follicles and stimulating hair growth.
Recommendations: The recommended daily dose of vitamin D is 600 IU (international units).
Sources: Bold fish (salmon, tuna, mackerel), egg yolks, products enriched with vitamin D, sunlight.

2.6 B vitamins (B1, B2, B3, B5, B6, B9, B12):

B vitamins play an important role in the general health of the body, including hair health. They participate in the metabolism of energy, the synthesis of blood cells and the functioning of the nervous system.

How they work: Different vitamins of group B perform different functions that are important for the health of the hair. For example, vitamin B5 (pantothenic acid) helps strengthen hair and give it shine, vitamin B6 (pyridoxine) is involved in the synthesis of protein and supports the health of the scalp, vitamin B12 (cobalamin) is necessary for the formation of red blood cells that carry oxygen to hair follicles.
Recommendations: Recommended daily doses of vitamins of group B vary depending on age, gender and health.
Sources: Whole grain products, meat, poultry, fish, eggs, dairy products, legumes, nuts, seeds, vegetables and fruits.

2.7 Vitamin C:

Vitamin C is a powerful antioxidant that protects the hair follicles from damage caused by free radicals. It is also necessary for the synthesis of collagen, a protein that strengthens the hair and gives it elasticity.

How works: Vitamin C neutralizes free radicals, preventing damage to the hair follicles. It also helps to absorb iron, which is necessary for hair growth.
Recommendations: The recommended daily dose of vitamin C is 75 mg for women and 90 mg for men.
Sources: Citrus fruits, berries, kiwi, pepper, broccoli, spinach.

2.8 Vitamin E:

Vitamin E is another powerful antioxidant that protects the hair follicles from damage. It also improves blood circulation in the scalp, which promotes hair growth.

How works: Vitamin E neutralizes free radicals and improves blood circulation in the scalp, providing hair follicles with the necessary nutrients.
Recommendations: The recommended daily dose of vitamin E is 15 mg.
Sources: Vegetable oils (sunflower, almond, olive), nuts, seeds, avocados, spinach.

2.9 omega-3 fatty acids:

Omega-3 fatty acids are indispensable fats that are necessary for the health of the skin and hair. They have anti -inflammatory properties and help improve the moisturity of the scalp.

How they work: Omega-3 fatty acids help reduce inflammation in the scalp, which can prevent hair growth. They also improve blood circulation and provide hair follicles with the necessary nutrients.
Recommendations: The recommended daily dose of omega-3 fatty acids varies depending on the source.
Sources: Fat fish (salmon, tuna, mackerel), linen seed, chia seeds, walnuts.
