The 5 best vitamins to prevent hair loss are essential for maintaining a healthy scalp and hair follicles. Biotin (vitamin B) is important for the body's cells, as it helps create red blood cells that carry oxygen and nutrients to the scalp. Vitamin C is essential for the intestine to absorb iron, which is necessary for red blood cells. Vitamin D is important for your bones, and collagen is an important part of your hair structure, but your body can't create it without vitamin C.
Vitamins and supplements that promise hair growth may seem too good to be true, but the right ones can make a difference in how your hair looks and feels. B-complex vitamins are essential for metabolism and nervous system function, and biotin (vitamin B7) is often touted as having benefits for hair growth. Biotin helps create red blood cells, which carry oxygen and nutrients to the scalp and hair follicles, and it also plays a role in the production of keratin, a major component of hair. Most people get enough biotin from the food they eat, but if you think you need an extra boost, talk to your doctor.
Vitamin C is a powerful antioxidant that is essential for healthy hair growth. Iron is also important for red blood cells, so make sure you consume enough iron-rich foods such as clams, red meat, spinach and lentils. Keratin is a protein that forms our hair, skin and nails, and there are many keratin supplements that claim to help with hair growth. However, it's best to get keratin in a more natural way by eating protein-rich foods such as eggs, beans, fish and meat.
Vitamin A deficiency may contribute to hair loss, but it's not common in the U. S., so there's no need to take supplements unless there is evidence of deficiency. Vitamin D deficiency can also cause hair loss, so make sure you get enough of this vitamin from foods such as salmon, mushrooms and egg yolks. Zinc is a trace element that plays a role in cell growth and DNA creation; make sure you consume enough zinc-rich foods such as meat, beans, nuts and seeds.
In addition to a diet rich in all the vitamins and minerals that can affect hair growth, there are a variety of over-the-counter supplements specifically aimed at those struggling with thinning or hair loss. Nutrafol contains vitamins A, D and C, biotin and zinc; Viviscal offers supplements for women and men; Hair Sweet Hair from Hum Nutrition is a line of vegan gummies designed to make hair stronger and healthier; and Gluten, Dairy, Soy, Hormones, Medications and Artificial Additives Nutraceuticals are specifically designed for women before, during and after menopause.
