What vitamins are good for hair growth

Biotin, also known as vitamin B7, or the ‘hair vitamin’, is a key nutrient involved in keratin production. Getting enough biotin helps keep hair strong and reduces breakage, contributing to thicker, fuller hair. Furthermore, Biotin helps maintain a healthy scalp by supporting the metabolism of amino acids and fatty acids, which are essential for nourishing hair follicles.

Good, natural sources of biotin include eggs (especially the yolk), nuts, seeds, sweet potatoes, spinach, and cauliflower.

Vitamin D helps to activate hair follicles, promoting healthy hair growth. If these follicles do not function properly, hair growth may slow down or cease, resulting in thinning or hair loss. A lack of vitamin D has been linked to alopecia areata, an autoimmune condition where the immune system attacks hair follicles.

Vitamin D can be found in oily fish, such as salmon and mackerel, dairy products, egg yolks, and mushrooms. Sunlight exposure also helps the body produce vitamin D naturally.

Vitamin E has strong antioxidant and nourishing properties that help protect hair follicles against oxidative stress caused by free radicals (unstable molecules that are capable of causing damage to cells in the body). It also boosts blood circulation to the scalp, ensuring hair follicles receive enough oxygen and nutrients essential for growth and strengthening hair strands. Additionally, vitamin E supports the scalp’s natural moisture balance, preventing dryness and flakiness that can impede healthy hair growth.

You can find vitamin E in nuts (like almonds and hazelnuts), seeds (such as sunflower seeds), spinach, broccoli, and plant oils like sunflower or olive oil.

Vitamin A supports the scalp in producing sebum, an oily substance that moisturises the scalp and keeps hair healthy and hydrated. Vitamin A is also essential for cell repair, including hair follicles, supporting the production of new, healthy hair.

Similar to vitamin E, vitamin A is an antioxidant, protecting hair follicles from damage caused by free radicals and environmental stressors.

Vitamin A can be found in foods like sweet potatoes, carrots, spinach, kale, and liver.

While vitamin A is vital, too much can lead to hair loss and toxicity. It’s important to keep intake within recommended levels.

Along with being a strong antioxidant, vitamin C plays a crucial role in collagen synthesis. Collagen is a protein that strengthens hair strands and helps maintain the structural integrity of hair follicles. Vitamin C also improves the absorption of iron, which helps red blood cells deliver oxygen to hair follicles.

Vitamin C is abundant in citrus fruits (oranges, lemons), strawberries, kiwi, bell peppers, and leafy green vegetables like spinach.

Iron helps to transport oxygen to hair follicles via red blood cells. Iron deficiency is a common cause of hair thinning and hair loss (telogen effluvium). Iron can be found in red meat, spinach, lentils, beans, and fortified cereals.

Zinc supports hair tissue growth and repair, and can also help maintain the oil glands around hair follicles, ensuring balanced sebum production. Zinc deficiency can lead to hair loss and scalp issues. Good sources of zinc include oysters, beef, pumpkin seeds, and chickpeas.

Omega-3 fatty acids are essential for nourishing hair and supporting scalp health by reducing inflammation that can lead to hair thinning. Omega-3 can be found in fatty fish (salmon, mackerel), flaxseeds, walnuts, and chia seeds.

Your hair is primarily made of the protein keratin, meaning adequate protein intake is vital for hair structure and growth. High sources of protein include meat, poultry, fish, eggs, dairy, nuts, and tofu.

Selenium helps the body synthesise antioxidants that protect hair follicles. It can be found in Brazil nuts, seafood, and eggs.

Silica supports hair strength and elasticity, and can be found in foods like bananas, oats, and green beans.
