Many vitamins are important for maintaining healthy hair. But their deficiency can have adverse effects on hair growth and thickness. Among the vitamins related to hair health, vitamin A, vitamin D, and vitamin E deficiencies are associated with hair loss.
Vitamin A is needed for cell growth, including the cells that make up hair follicles. Its deficiency leads to hair breakage. Vitamin A plays a role in sebum production. It is an oily substance that keeps skin moist and hair healthy. Without enough vitamin A, the scalp becomes dry. Hair breaks easily.
Vitamin D deficiency causes hair loss. Vitamin D plays an important role in regulating the hair growth cycle. It supports healthy follicles. Vitamin D deficiency disrupts this cycle. This leads to hair loss and loss of hair density. Adequate intake of vitamin D through sunlight, diet, and supplements is important to maintain hair health.
Vitamin E is known for its antioxidant properties. It helps protect the cells in the follicles from oxidative stress. Vitamin E deficiency increases oxidative damage. It negatively affects healthy hair. Also, vitamin E contributes to a healthy scalp. Its deficiency contributes to dryness and swelling. These are the factors that lead to hair thinning.
B-vitamins play an important role in the metabolism of amino acids. Since hair is made up of keratin, molecules that make proteins, healthy hair growth requires an adequate supply of B-vitamins. Biotin is especially linked to hair health. Its deficiency is associated with hair thinning and hair loss. Vitamin B6, B12 are important for maintaining healthy hair because they contribute to the production of red blood cells, which provide nutrients and oxygen to the hair follicles.
