Vitamins and minerals are essential for healthy hair and nail growth. While there are many nutrients that are important for the body's health, specific nutrients support beauty. For instance, vitamin A, vitamin C, biotin, and hyaluronic acid are all important for hair and nail health. Biotin is a B-complex vitamin that aids in the metabolism of protein-building amino acids that are essential for nail growth. Vitamin C is essential for the production of collagen, which is a protein that gives shape, strength, and integrity to many tissues and is the building block of fingernails, hair, and teeth. Hyaluronic acid is found in many areas of the body, including the skin, eyes, and synovial fluid of the joints, and it decreases with age. In addition to vitamins, healthy fats and proteins are also important for hair and nail growth.

Vitamin A, found in dairy, eggs, fish, and meat
Vitamin A is a fat-soluble micronutrient that is necessary for the growth of healthy skin and hair. It is also known as retinol or vitamin A1. It is found in many multivitamins, as well as in dairy, eggs, fish, and meat.
Vitamin A is found in animal-sourced foods, such as oily fish, liver, cheese, and butter. It is also present in certain vegetables and fruits, including kale, spinach, mango, and guava. However, vitamin A derived from animal sources is more efficiently absorbed into the bloodstream as these foods are typically also high in fat.
Vitamin A plays a critical role in maintaining vision, growth, immune function, and reproductive health. Adequate consumption of vitamin A is necessary for the maintenance of healthy skin and hair. It affects the skin and hair in a dose-dependent manner, where too much or too little can have negative consequences. For example, symptoms of vitamin A deficiency include hair loss, skin problems, dry eyes, night blindness, and increased susceptibility to infections.
Vitamin A regulates the hair cycle and influences the functioning of the hair follicle stem cells. Studies have shown that mice fed higher levels of vitamin A exhibited more hair follicles in the refractory telogen phase. Additionally, vitamin A is necessary for the phototransduction cascade that initiates melanogenesis.
By including vitamin A in your diet through the consumption of dairy, eggs, fish, and meat, you can support the growth of healthy hair and nails while also benefiting your overall health.

Biotin, a B-complex vitamin, found in eggs, meat, and nuts
Biotin, also known as vitamin B7, is a B-complex vitamin that helps convert food into energy. It is found in a variety of foods, including eggs, meat, fish, seeds, nuts, and some vegetables, such as mushrooms and sweet potatoes. Biotin is also available in supplement form.
Eggs, especially egg yolks, are a good source of biotin. A cooked egg contains 10 micrograms of biotin, while other sources estimate that egg yolk contains 0.3 micrograms of biotin per cup of 2% milk. In addition to biotin, eggs also contain other B vitamins, making them a nutrient-rich food that supports overall health.
Meat, particularly organ meats like liver, are another excellent source of biotin. Just 3 ounces (75 grams) of cooked beef liver provides nearly 31 micrograms of biotin, which is more than the recommended daily intake for adults. Chicken liver is an even richer source, with a 3-ounce serving containing 138 micrograms of biotin.
Nuts and seeds are also a good way to increase your biotin intake. Sunflower seeds, almonds, walnuts, and peanuts are all nuts that contain significant amounts of biotin. For example, just six walnut halves contain 9.5 micrograms of biotin, while a quarter-cup of roasted almonds provides 1.5 micrograms.
While biotin is known to support overall health, its specific benefits for hair and nail growth are less clear. Some research suggests that biotin supplements may help manage symptoms of diabetes and certain medical conditions affecting hair growth, such as alopecia. However, there is limited evidence to show that biotin effectively promotes hair growth or strengthens nails in individuals without these specific conditions. Nonetheless, maintaining adequate levels of biotin through a balanced diet or supplements may support overall health, including the health of your hair and nails.

Vitamin C, found in citrus fruits, broccoli, and bell peppers
Vitamin C is also crucial for hair health. It helps combat hair loss and helps retain natural hair colour by preventing premature ageing of the hair. Vitamin C helps fight bacteria on the scalp and prevents dandruff, thus encouraging the growth of new hair. It also helps with dry and itchy scalps due to its antiviral properties. Additionally, it improves blood circulation and strengthens and repairs capillaries, resulting in stronger, thicker hair.
Vitamin C can be incorporated into your diet in various ways, including food, serums, facemasks, shampoos, and vitamin supplements. Citrus fruits such as oranges, strawberries, and kiwi are excellent sources of vitamin C. However, if you are looking for non-citrus options, broccoli and bell peppers are also rich in this nutrient.
While vitamin C is essential for hair and nail health, it is important to maintain a balanced diet and not rely solely on one vitamin or supplement. A variety of vitamins and minerals play a role in new hair growth and overall health. Additionally, addressing nutrient deficiencies may help treat and prevent hair loss. Consulting with a healthcare professional before starting any supplements is always recommended.

Collagen, a protein found in animal foods like meat and fish
Collagen is a protein that is important for many parts of the body, including the skin, hair, nails, teeth, organs, tendons, and cartilage. Collagen is found in animal foods like meat and fish, and foods made with animal-based gelatin also contain collagen. Our bodies make collagen from the amino acids found in the proteins we eat, but as we age, our bodies produce less collagen.
Collagen peptides powder is a popular supplement for hair, nail, skin, bone, and joint health. It is available in unflavored and flavored options and can be mixed into hot and cold liquids. Some people have reported positive effects on hair growth, stronger nails, and more youthful skin. However, the taste, value for money, and pain relief from joint pain have shown mixed results.
Collagen is the building block of fingernails, hair, and teeth, and it gives shape, strength, and integrity to many tissues in the body. Vitamin C is essential for the production of collagen, and it is found in citrus fruits like oranges, strawberries, and kiwi, as well as bell peppers, green vegetables, and tomatoes.
While supplements and nutritious diets can help support healthy nails, it is important to note that consuming too much of one vitamin or taking unnecessary supplements can be detrimental. For example, taking extra zinc can lead to a loss of copper, which is important for bone health. Instead of relying solely on supplements, it is recommended to maintain a balanced diet with a variety of foods to supply the necessary healthy fats, carbs, protein, vitamins, and minerals.

Hyaluronic acid, found in topical treatments, ingestible supplements, and injectable fillers
Hyaluronic acid is a naturally occurring substance in the body, found in the fluid in our eyes, joints, and skin. It is a humectant, which means it can retain water and draw moisture to the skin's surface, providing hydration. This makes it an excellent ingredient in skincare products, where it is known for its moisturising and anti-ageing properties.
When it comes to hair and nails, hyaluronic acid can be beneficial too. Topical treatments containing hyaluronic acid can help improve the appearance of hair, making it look smoother and less frizzy. This is because hyaluronic acid can absorb water, adding moisture to hair follicles and reducing porosity, which minimises moisture loss. It can also help to seal the cuticle, preventing unwanted moisture that causes frizz. It is safe for all hair types and textures and can be particularly beneficial for those with dry, damaged, or frizzy hair.
Hyaluronic acid can also be taken as an ingestible supplement, which may provide similar benefits to the hair and scalp. It is important to note, however, that there is limited research on the potential benefits of hyaluronic acid for hair care, and it is always advisable to consult a doctor before taking any supplements.
Additionally, hyaluronic acid injections, also known as fillers, are available from dermatologists, offering further skin benefits.
