Why Your Hair is Falling Out: The Surprising Link to a Missing Nutrient

Selenium: Protecting Against Oxidative Stress

Selenium is a trace mineral that plays a critical role in the body's antioxidant defense system. It helps protect hair follicles from oxidative damage caused by free radicals. Selenium also supports the thyroid gland, which regulates hormones that impact hair growth. A deficiency in selenium can lead to hair loss and a dry, flaky scalp. Brazil nuts are one of the richest sources of selenium, but it can also be found in seafood, eggs, and sunflower seeds. As with zinc, moderation is key, as excessive selenium can also contribute to hair loss.

Vitamin A: Balancing Sebum Production

Vitamin A is vital for the production of sebum, the oily substance that moisturizes the scalp and keeps hair healthy. However, both deficiency and excess of vitamin A can lead to hair loss. A lack of vitamin A can result in a dry, itchy scalp, while too much can trigger hair shedding. Balancing vitamin A intake is crucial, and it can be achieved through a diet that includes carrots, sweet potatoes, and dark leafy greens. These foods provide beta-carotene, which the body converts to vitamin A as needed, helping maintain optimal levels.
