What You'll Learn
Biotin (vitamin B7) supplements may help with hair and nail strength
Biotin, also known as vitamin B7 or vitamin H, is a water-soluble vitamin that helps the body metabolize fats, carbohydrates, and proteins. It is also necessary for several other functions, including maintaining a healthy nervous system, nails, hair, and skin. While biotin is naturally present in many foods, such as red meat, eggs, seeds, and nuts, some people may consider taking supplements to improve their hair and nail health.
Biotin supplements are often marketed as a way to promote hair and nail growth and strength. However, it is important to note that research on the effectiveness of biotin supplements for hair and nail health is limited. While biotin deficiency can lead to hair loss and skin problems, it is rare. Most healthy individuals meet their daily biotin requirements through a well-balanced diet.
That being said, there is some evidence to suggest that biotin supplementation may be beneficial for individuals with certain medical conditions affecting hair and nail growth. For example, biotin supplements have been shown to improve hair quality in patients with uncombable hair syndrome and alopecia. Additionally, three cases of brittle nail syndrome treated with biotin supplementation showed improvement in nail strength and growth.
Furthermore, biotin supplements may be recommended for specific populations, such as pregnant women, who are at a higher risk of biotin deficiency. It is always a good idea to consult with a healthcare professional before starting any new supplement to ensure it is safe and appropriate for your individual needs.
While diet is a significant factor in hair, skin, and nail health, it is important to remember that a balanced diet that includes a variety of nutrients is generally the best approach to support overall health and well-being.

Collagen supplements may support hair and nail health
While a healthy diet is the best way to ensure adequate nutrition, supplements can help provide the right vitamins and nutrients to support hair and nail health. Collagen is a protein that supports skin elasticity, strengthens nails, and promotes joint, muscle, and bone health. Our bodies naturally produce collagen, but this production decreases with age, sun damage, smoking, and alcohol consumption.
Collagen supplements are often derived from bone broth, meat, fish, cattle, pigs, or chicken, and they typically contain peptides (short chains of amino acids) that help make up essential proteins in the body, including collagen and keratin, which form skin, hair, and nails.
Some people report that collagen supplements have helped improve their hair, nail, and skin health. For example, one user of Nature's Bounty Extra Strength Hair, Skin, and Nails supplements with hyaluronic acid and collagen noticed brighter skin and thicker nail growth. Another user of Persona's hair, skin, and nail vitamin, which also contains collagen, reported similar results. Additionally, a small 2017 study of 25 people with brittle nails found that taking 2.5 grams of collagen daily for 24 weeks improved nail brittleness and growth.
However, it is important to note that there is limited scientific evidence supporting the use of collagen to enhance hair and nails. No human studies have clearly proven that orally ingested collagen will end up in the skin, hair, or nails. While some studies suggest that collagen supplements can improve skin moisture, elasticity, wrinkles, and roughness, there is a lack of large-scale, high-quality studies to confirm these findings and determine the safety of long-term use.
If you are considering taking collagen supplements, it is recommended to consult your doctor first, especially if you have any medical conditions or dietary restrictions.

Iron deficiency can cause hair shedding
While hair, skin, and nail vitamins can help improve hair health and growth, iron deficiency is a common cause of hair shedding. Iron plays a crucial role in making hemoglobin, a protein compound that carries oxygen to the body's cells, which is essential for cell health and growth. When there is insufficient iron in the body, it can lead to iron deficiency anemia, which may result in hair loss or brittleness.
Hair shedding due to iron deficiency is often temporary and reversible. It is important to consult a doctor to determine the underlying cause of hair loss and seek appropriate treatment. Doctors may recommend iron supplements or injections to raise iron levels. Additionally, dietary changes can help increase iron intake, including consuming iron-rich foods such as red meat, chicken, fish, leafy greens, and legumes, and iron-fortified cereals.
It is worth noting that hair, skin, and nail vitamins may contain ingredients like biotin, collagen, hyaluronic acid, and keratin, which can contribute to overall hair health and growth. However, the effectiveness of keratin supplements is not yet fully understood. While these vitamins can support hair growth, addressing any nutrient deficiencies, such as iron deficiency, is fundamental to promoting healthy hair.
A balanced diet is crucial to ensuring adequate nutrient intake for hair, skin, and nail health. In addition to iron-rich foods, consuming healthy fats, proteins, carbohydrates, vitamins, and minerals can promote optimal hair, skin, and nail health. While supplements can be beneficial, they should not replace a well-rounded diet, as the body primarily requires a variety of nutrients to function effectively.
In summary, iron deficiency can lead to hair shedding, but it can be addressed through medical advice, dietary changes, and, if necessary, supplements. Maintaining a balanced diet that includes a range of nutrients is key to supporting hair, skin, and nail health, as well as overall well-being.

Vitamin D supports hair growth
While there are many factors that influence hair growth, vitamin D is one of the essential vitamins and nutrients that can support hair growth and overall hair health. Vitamin D plays a vital role in promoting healthy hair follicles and enhancing hair growth.
Vitamin D is a nutrient that the body needs for overall health and well-being. It is produced by the body when the skin is exposed to sunlight, but it can also be obtained through certain foods and supplements. Vitamin D is intricately involved in various signalling pathways of growth and differentiation of hair follicles.
A deficiency in vitamin D can contribute to hair loss and decreased hair volume. Studies have shown an inverse relationship between serum vitamin D levels and certain types of alopecia, including telogen effluvium, androgenetic alopecia, alopecia areata, and trichotillomania. Vitamin D deficiency is also associated with scarring alopecia.
To ensure optimal vitamin D levels for hair health, it is recommended to choose vitamin D3 supplements, as this form is considered the most effective. A daily dosage of 5,000 IU of vitamin D is suggested by experts to achieve optimal levels and support hair follicle health, contributing to healthy hair growth.
In addition to vitamin D, other vitamins and minerals that promote hair growth include vitamins A, C, E, B6, B12, B5, and B7 (biotin), as well as iron, magnesium, zinc, selenium, and chromium. A balanced diet that includes a variety of healthy fats, proteins, carbohydrates, vitamins, and minerals is essential for maintaining healthy hair, skin, and nails.

Healthy fats and proteins are essential for hair health
Diet is a major factor in the condition of your hair, skin, and nails. Healthy fats and proteins are essential for hair health. Fatty acids and proteins are among the vitamins and minerals that work together to keep hair strong and healthy.
Fatty acids help lock moisture into your hair, skin, and nails. Salmon, sardines, mackerel, and rainbow trout are rich sources of omega-3 fatty acids, which are essential for a healthy scalp and hair. Omega-3 fatty acids also help protect you from disease. Your body cannot produce these healthy fats, so you must obtain them from food or supplements.
Protein is another essential nutrient for hair health, as hair is primarily made of protein. A lack of protein can cause hair growth to slow or stop, and old hairs to fall out. Fatty fish, lean meats, eggs, and nuts are all good sources of protein.
Some hair, skin, and nails vitamins can help address deficiencies and support your beauty goals. Olly Undeniable Beauty Hair, Skin, and Nails vitamins, for example, contain biotin and keratin. However, taking too much of one vitamin or mineral may deplete another, so it is important to maintain a balanced diet.
