A healthy and balanced diet greatly contributes to health and well-being. It also plays a role at the hair level and helps to strengthen hair and eyebrows. Indeed, a diet rich in nutrients such as vitamin B, magnesium, and iron helps to strengthen hair follicles and thus contributes to eyebrow care. These nutrients are particularly found in whole grains, legumes, certain meats, and some fish.
The underlying mechanisms vary depending on the nutrients. In the case of iron, it is known that this element is a cofactor of the ribonucleotide reductase, an enzyme that limits the speed of DNA synthesis. The cells of the hair follicle matrix are among the cells that divide the fastest in the body and can be extremely sensitive even to a minor decrease in the availability of iron. Thus, an iron deficiency can lead to a decrease in eyebrow growth.
It should also be noted that vitamin B deficiencies have been linked to hair loss. Although the mechanisms at work are not fully understood, it is known that certain forms of vitamin B, such as vitamin B2, play a role in cellular development and energy production. Lastly, magnesium is necessary for the activation of enzymes involved in protein synthesis, including keratin. These enzymes are responsible for converting amino acids into polypeptide chains, which then combine to form the structure of keratin.
The consumption ofantioxidants, such as vitamins A and E, flavonoids, and carotenoids, is also recommended. These compounds protect the cells of our body from free radicals, including those at the eyebrow level. Free radicals, generated by overexposure to the sun, tobacco, or even an unbalanced diet, damage cells and DNA. They can also attack the hair follicles of the eyebrows and disrupt their cycle, causing them to enter the telogen, or shedding phase, more quickly. However, free radicals can be neutralized by antioxidants. Spices like turmeric and saffron, dried fruits and nuts, green tea, broccoli, artichokes, salmon, and red tuna are all foods rich in antioxidants.
