The adult scalp contains about 100,000 hair follicles. Everyday the scalp loses about 100 hairs and they will grow back in 5-6 weeks. Starting at age 40, the levels of by-product prolactin of testosterone of men increases, stimulating the production of the enzyme 5-alpha reductase that causes the conversion of testosterone to gihydro-testosterones DHT causing our hair to grow back thinner or not grown back at all. This causes an androgenic alopecia hair loss problem, since DHT shrinks the follicles causing hair thins and hair receding at the forehead, crown and temple for men and thins over the entire scalp for women.
1. The Causes of Hair Loss
Human aging is the biological process that is unavoidable but controllable with healthy diet with complex carbohydrates, green foods, garlic, onion, water and juices that will help to decrease the aging process in some degree. It also helps to reduce the amount of DHT produced in our body, result in postponing hair loss to our scalp.
Minerals such as calcium, iron, copper, chromium, iodine, zinc, and magnesium are necessary to maintain healthy hair growth. Mineral deficiency will reduce the chance to regulate the blood circulation that promotes healthy hair growth and thyroid hormones that prevent dry hair and hair loss as well as defects in hair color. Too much iron is toxic to your body. Be sure to talk to your doctor before taking any mineral supplement.
Oxygen deficiency in your blood weakens the hair follicles, leading to dryness of the scalp and hair loss. Uncontrolled diet that is high in saturated fat causes cholesterol building up in your arteries resulting in less oxygen in your blood stream. Also cigarette smoking and second hand smoke reduces the blood flow and increases the blood clotting activity of cells which would clog the blood flow and damage arteries causing oxygen deficiency and results in weaken of the hair follicles.
Side affects of medication taken
Some medications contains elements that might cause hair loss such as lithium, warfarin, heparin, and amphetamines. When hair loss is a side effect of a medication, hair growth usually returns to normal once the drug is stopped.
Genetic hair loss
Hair loss is due to heredity. It is passed down from generation to generation. Genetic hair loss appears predominately in men, but may also appear in a few select women.
2. Food to Avoid
Foods that can cause hair loss and diminish hair growth.
Saturated and Trans fat
Foods such as meat, poultry, and fried foods contain high saturated fat. Foods such as margarine, cheese, and butter contain high amounts of trans fat. These foods cause cholesterol to build up in your arteries and small veins in your scalp resulting in less oxygen being delivered to the cell in your body, including the cells on the follicles.
Foods that contain Aspartame and Monosodium Glutamate
Monosodium Glutamate contain chemicals that causes weight gain, increased appetite and also causes various kinds of health problems such as hair loss.
Aspartame contains toxic chemicals that make you gain weight, increases hunger and causes medical problems like migraines and poor blood circulation.
As we mentioned in the previous article, smoking can reduce blood flow to the scalp causing hardening in the arteries, limit blood flow and make hair loss worse.
Artificial color contains chemical compounds that take their toll on the body’s natural balance.
Specific foods to avoid include colored drinks, color-coated candies, gummy and chewy candies, and many colored cereals.
These are potentially toxic to the liver and kidneys that cause hair loss and prevent hair growth as we mentioned in the article “Hair loss part IV–regrow hair with Chinese herbs”.
Polyvinyl chloride is a known carcinogen, and it’s often used as plastic food wrap. It is toxic with high amounts causing damage to the kidney and liver resulting in hair loss.
Eating too much salt can lead to fluid retention and increased blood pressure that cause less oxygen to be delivered to the body’s cells including cells in your scalp in result of losing hair.
