The adult scalp contains approximately 100,000 hair follicles. The scalp loses about 100 hairs per day, but these hairs grow back after 5 to 6 weeks; after the age of 40, the amount of prolactin, a by-product of testosterone, increases in men, which stimulates the production of the enzyme 5-alpha-reductase, which converts testosterone into DHT, resulting in thinning hair or no hair growth at all. DHT causes hair follicles to shrink, resulting in thinning of the forehead, parting, and temples in men and the entire scalp in women, hence the problem of hair loss in androgenetic alopecia. Causes of hair loss.
1) Causes of hair loss
a) Aging
Human aging is biologically unavoidable, but a healthy diet consisting of complex carbohydrates, green foods, garlic, onions, water, and juice can reduce it to some extent. It can also reduce the amount of DHT produced by the body, which can slow scalp hair loss.
b) Mineral deficiencies
Minerals such as calcium, iron, copper, chromium, iodine, zinc, and magnesium are essential for proper hair growth. Mineral deficiencies reduce the body’s ability to regulate thyroid hormones, which promote healthy hair growth, stimulate blood circulation and prevent dry hair, hair loss, and color defects. Too much iron is poisonous to the body. Always consult a doctor before taking mineral preparations.
c) Lack of oxygen
A lack of oxygen in the blood weakens the hair follicles, resulting in dry scalp and hair loss. A diet rich in saturated fatty acids leads to an accumulation of cholesterol in the arteries and a lack of oxygen in the blood. Smoking and passive smoking also reduce blood flow and increase the clotting activity of blood cells, which obstructs blood flow and damages the arteries, resulting in a lack of oxygen and weakening the hair follicles.
d) Side effects of ingested medications
Some medications, such as lithium, warfarin, heparin, and amphetamines, contain components that can cause hair loss. If hair loss is a side effect of the medication, hair growth usually returns to normal when the medication is stopped.
e) Genetic hair loss
Hair loss is genetically inherited. It is passed on from generation to generation. Hereditary hair loss affects mainly men, but also some women.
2. Foods to avoid
Foods that can cause hair loss or slow down hair growth.
a) Saturated and trans fats
Foods such as meat, poultry, and fried foods contain a high proportion of saturated fatty acids. Foods such as margarine, cheese, and butter contain a high proportion of trans fatty acids. These foods cause cholesterol to build up in the arteries and small veins of the scalp and reduce the supply of oxygen to the cells of the body, including the cells of the hairline.
b) Products containing aspartame and monosodium glutamate
MSG contains chemicals that cause a variety of health problems, including weight gain, increased appetite, and hair loss.
Aspartame contains harmful chemicals that can cause weight gain, increased hunger, and health problems such as migraines and cardiovascular problems.
c) Smoking
As mentioned in previous articles, smoking can reduce blood flow to the scalp, which leads to atherosclerosis, limits blood flow, and increases hair loss.
d) Artificial dyes
Artificial dyes contain chemicals that disturb the body’s natural balance.
Foods to avoid are colored drinks, colored candies, chewy candies, and many-colored cereal products.
e) Preservatives
May be toxic to the liver and kidneys, cause hair loss and inhibit hair growth, as described in Hair Loss Part 4 – Hair Growth with Chinese Medicine.
f) Food packaging
Polyvinyl chloride is a known carcinogen and is often used as a plastic packaging material for food. Ingested in large quantities, it is toxic and can cause kidney and liver damage and hair loss.
g) Salt
Excessive salt consumption can lead to water retention in the body and increased blood pressure, which reduces oxygenation of the body’s cells, including those in the scalp, and leads to hair loss.
3) Prevention and treatment of hair loss
- Here are some important minerals for the prevention of hair loss and the promotion of hair growth
a) Iron
Iron is involved in the oxygenation of red blood cells in the body. It is important for normal hair growth and health. If iron is not supplied by the diet, an iron deficiency leads to a lack of oxygen and increased hair loss.
b) Zinc
Zinc helps the scalp produce the necessary oils and prevents dandruff, which leads to hair loss.
c) Copper
Studies have shown that this tripeptide complex can actually regrow hair, even in patients who have lost their hair completely due to alopecia. The concentration of copper in healthy tissue is 1.7 to 3.5 milligrams. Any other amount can cause hair loss.
d) B vitamins
A deficiency of B vitamins (especially B6, B3, B5, and folic acid) in the diet can cause hair loss.
e) Biotin
Biotin prevents aging, promotes keratin production, and prevents gray hair and hair loss.
Sources of biotin include whole grains, egg yolk, liver, rice, and milk.
f) Vitamin A
Vitamin A is important for general health. It is also beneficial for hair follicles, as it keeps them moist. Hair loss can be caused by too much vitamin A.
g) Vitamin E
Vitamin E plays an important role in promoting hair growth and preventing hair loss because it is an antioxidant that increases oxygen uptake into the blood and promotes efficient blood flow to the scalp.
h) CQ-10
Coenzyme Q10 (CQ-10) is an important vitamin that provides the body with the nutrients it needs for healthy hair growth. It also contributes to overall vitality and promotes beautiful skin and strong nails.
Daily foods that prevent hair loss and promote hair growth.
1. Yogurt and soy
Yogurt and soy are rich in protein, which is important for hair growth. Research has shown that soy protein strengthens hair and promotes hair growth.
2. Dark green vegetables
Dark green vegetables are rich in iron, which is essential for restoring oxygen levels in the blood and nourishing the body’s cells.
3. Whole grains
Whole grains contain zinc, which is essential for maintaining healthy hair. Zinc deficiency can lead to dry hair and oily skin.
4. Essential fatty acids
Essential fatty acids are found in large quantities in cold water fish. They help maintain healthy cholesterol levels and reduce triglyceride levels by improving blood circulation in the body.
5. Nuts and seeds
Nuts and seeds are fatty foods that generally have the highest content of vitamin E, an antioxidant that strengthens the immune system and protects the nerves. Vitamin E deficiency can lead to skin irritation, dryness, and hair loss.
6. Carrots
Carrots are rich in vitamin A. It has antioxidant properties and helps the scalp produce healthy sebum. Too much vitamin A can lead to hair loss.
There are many other foods that promote hair growth and prevent hair loss, such as fruits, eggs, spinach, and broccoli.
Always consult your doctor before consuming large amounts of any of the above foods. An overdose of vitamin A in carrots can lead to hair loss and other side effects.
