- Biotin – Biotin is a water-soluble vitamin that is originally a part of the B Vitamin (B7) family. It aids the body in metabolizing carbohydrates, fats, and protein, converting them into energy. Since it’s a water-soluble vitamin, it cannot be stored in the body. Therefore, biotin stores in the body need to be continuously replenished. Biotin helps to strengthen the protein (keratin) structure of the hair shaft.
- Protein – The infrastructure of the hair is made up of hardened proteins called Keratin. Keratin is a protective protein, shielding epithelial cells from damage. It is also less prone to tearing or scratching than any other type of protein cells in the body.
- Omega-3 Fatty Acids – Omega-3 Fatty acids are a group of unsaturated fatty acids that are crucial parts of human cell membranes. They are present in the scalp skin, as well as in the natural oils produced by the scalp and skin to stay moisturized and healthy. If you’re deficient in Omega-3 fatty acids, it can result in a dry scalp and dry and dull hair.
- Iron – When iron levels in the body are low, it diminishes the iron storage in the body.
- Zinc – Zinc is an essential trace mineral that is not naturally produced in the body. Zinc is essential for protein synthesis, growth, and development in the human body. Even though zinc does not directly affect hair growth, it keeps the hair healthy and strong, all of which is essential for the hair to grow.
- B Vitamins – Other than Biotin, your hair also needs other B-Vitamins. These include Vitamin B6, B12, and Folate. They also produce new cells in the body, which naturally improves the texture and quality of your hair.
- Vitamin C – Moreover, Vitamin C helps the body absorb iron, which, as mentioned above, is an essential nutrient for hair.

What the Research Says
The FDA doesn’t define “organic” or “natural” for cosmetics; a product can carry the USDA Organic seal only if its agricultural ingredients meet USDA standards.[3][1] Plant ingredients can still cause allergic reactions, and fragrance is a common cause of skin irritation.[4] Cosmetics can’t legally claim to treat or cure skin conditions; products that do are regulated as drugs.[5]Sources
