Zinc is a natural trace element which is present in the body. It’s involved in regulating many functions such as; maintaining normal hormonal balance and producing new cells. It also helps to absorb the correct amount of minerals, vitamins, and maintaining protein synthesis. These processes are important for hair growth and hair rebirth. Therefore, the correct amount is needed for the prevention of hair loss and hair thinning.
Mechanisms of Zinc in Promoting Hair Health
Since zinc is directly linked to building protein in the body, it plays a great role in the production of the hair-forming protein ‘keratin’. This keratin makes up the structure of the hair follicle. If you have a zinc deficiency, the keratin formation is stopped. This leads to weaker hair follicles and even hair thinning and hair loss. The mineral also prevents hair loss as it maintains the hormonal balance in the body.
Deficiency of thyroid hormone leads to hair loss in an individual. Therefore, the mineral is necessary in keeping the normal levels of this hormone in the body. A lack of it disturbs the function of the thyroid gland, which in turn leads to a chronic hair loss.
Zinc deficiency in the body can easily be treated with an increased intake of zinc-rich foods or hair growth supplements that contain the mineral. This has been shown to have positive results on hair growth, hair rebirth, and in preventing hair loss. Foods with high amounts of the mineral are oysters, nuts, eggs, chickpeas, sweet potatoes, and spinach. Sweet potatoes are also a great source of omega-3 fatty acids, which have antioxidant properties and stop free radical formation in the body. These free radicals greatly damage the hair follicles.
