HOW NUTRITION AFFECTS THE WELL-BEING OF HAIR

According to several scholars, an unbalanced and poorly balanced intake can help if not determine hair loss.

But what is in the hair?

As we have said before, the hair is made up of a large part of keratin, an insoluble protein consisting of amino acids (predominantly cystine). Keratin can be deformed by water vapor (this is why “styling” is compromised by bad weather!) Which acts at the level of weak hydrogen bonds, or it can be permanently deformed if the disulfide bridges are broken (which occurs in the chemical process of the permanent).

It has been shown that the persistence of too restrictive diets leads from the reduction of melanin to the complete atrophy of the hair follicle. And what is puzzling is that these physiological alterations occur when there is still no evidence of protein deficiencies in the blood. This means that in situations of stress the human body prefers the safeguarding of vital functions by penalizing the health of those parts that it can do without. Our luck is that, if taken in time, this situation is reversible thanks to an external protein supply.

Also, the use of drugs that alter the absorption of food and intestinal disorders can favor a decrease in the vitality and shine of our hair.

The amino acids our hair needs are found in the foods we commonly consume, for example, cysteine, which gives resistance and resistance to keratin fibers, we can find it in eggs and cow’s milk; phenylalanine and tyrosine, responsible for the production of melanin and therefore the color of our hair, are abundant in flour and gluten.

VITAMINS ARE ESSENTIAL FOR HAIR HEALTH.

Certainly, a predominant role in the capillary physiology is played by vitamins (it is not by chance that the word “vitamin” indicates a fundamental amino structure for life).

The most important are:

  • vitamin A (retinol) which we find in the food of animal origin and their derivatives (eggs, milk, cheese). Its daily requirement is 5000 IU where a UI corresponds to 0.334 mg, but be careful not to abuse it! In fact, an excessive amount of vitamin A in the body can cause imbalances and have a negative effect on the synthesis of keratin
  • vitamin E (tocopherol) abundant in vegetable oils and butter. Very well known for its antioxidant function, it plays a primary role in protecting against free radicals, which causes premature aging of our membranes. Its daily requirement is 15 IU or 15 mg.
  • vitamin C (ascorbic acid). It is the most widespread and commonly used vitamin (especially in the cold season!) And is one of the few water-soluble vitamins that our body can accumulate (but also be careful not to overdo it!). It is a powerful antioxidant and its requirement is around 75 mg per day.
  • group of B vitamins widely used in many foods (especially meat, vegetables, and flour) with trophic action on cellular metabolism

Finally, the last large group of substances essential to our well-being are trace elements such as iron (abundant in red hair), zinc, copper, and magnesium (especially present in black hair) without which our vital functions would be seriously compromised.

I, therefore, conclude by stating that the health of our hair and in general of our body is determined in an important way by how we feed ourselves, so if we want to guarantee our hair bulbs a lasting life and a constant production I recommend nothing is more valid than the classic Mediterranean diet!
