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 healthy hair growth. Therefore, the correct amount is needed to help aid in 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, which makes up the structure of the hair follicle. If you have a zinc deficiency, the keratin formation is stopped. This can lead 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 can lead to chronic hair loss.
Zinc deficiency in the body can easily be treated with an increased intake of zinc-rich foods or hair supplements that contain the mineral. This has been shown to have positive results on the overall health of one’s hair. 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 can greatly damage the hair follicles.
