How Nutrition Impacts Hair

Vitamin E

Vitamin E is an antioxidant that protects your cells from damage. It is found naturally in many foods and is fat-soluble. It’s well-known for its skin-nourishing and hydrating properties, which it has been since the 1950s.

The scalp is an important area of the skin that’s often overlooked. It can protect your scalp and keep it healthy. It can reduce the amount of oxidative stress your scalp experiences, which is particularly important for hair loss. You can avoid an E vitamin deficiency by eating various leafy green vegetables, sunflower seeds, and nuts.

Folic Acid

Prenatal supplements often contain folic acid because it plays an essential role in the development of the fetus. Folic acid also stimulates cell growth, which in turn boosts hair growth. Maintaining normal oxygen levels can help to prevent premature graying. Folic acid deficiency can lead to hair loss. You might consider taking a Supplement with Folic acid to keep your hair shiny and healthy.

Additional Vitamins and Nutrients

Maintaining your hair’s natural look and feel takes more than just a few products. An integrated approach to hair wellness that considers all aspects of hair can help lower stress levels and promote hair health.

Essential Fatty Acids

The body will be able to grow hair and decrease inflammation with the Omega-3 and Omega-6 fatty acids. Conversely, a fatty acid deficiency can cause hair loss in your scalp and brows. Flaxseed, walnut, and other dedicated daily supplements can help increase your essential fatty acids intake.

Vitamin C

The body can produce collagen by keeping vitamin C levels in check, promoting healthy hair growth. Vitamin C is an antioxidant that aids in hair growth. It also helps to absorb zinc which can help prevent hair loss. Blackcurrants and kiwi fruits, kale, oranges, and strawberries are all excellent sources of vitamin C to help you avoid vitamin deficiencies.

Amino Acid

A protein or amino acid shortage can cause hair loss and thinness. Acid acids improve the body’s function by regulating hormones and tissue repair. They are also helpful in breaking down food and maintaining immunity. A diet high in legumes, soybeans, tomatoes, beans, seeds, cabbage, and spinach will ensure that you get enough amino acids.
