1. Protein – Nutrients for hair health

Hair is primarily composed of a protein called keratin, which forms the structural foundation of each strand. Adequate protein intake is vital for maintaining the strength and integrity of hair.

A study published in the Journal of Investigative Dermatology highlighted the adverse effects of protein malnutrition, including hair thinning and loss.

Incorporating protein-rich foods such as lean meats, eggs, and legumes into your diet can support keratin production and promote healthy hair growth.

2. Biotin (Vitamin B7)

Biotin, also known as vitamin B7, is crucial in keratin production, enhancing hair growth and strength. Research in the Journal of Clinical and Aesthetic Dermatology demonstrated that biotin supplementation significantly improved hair growth among individuals with thinning hair. Biotin can be found in foods like eggs, nuts, and whole grains, making it an accessible nutrient for hair health.

3. Iron

Iron is essential for hair growth as it aids in the transportation of oxygen to hair follicles. A study in the Journal of the American Academy of Dermatology found a link between iron deficiency and hair loss, particularly in women.

Ensuring adequate iron intake through dietary sources such as red meat, spinach, and lentils or supplements can promote hair growth and prevent hair loss.

4. Vitamin C

Vitamin C is a powerful antioxidant that protects hair from oxidative stress caused by free radicals. It also plays a crucial role in collagen production and enhances iron absorption.

A study in the Journal of Trichology emphasised the importance of vitamin C in preventing hair loss and maintaining healthy hair. Citrus fruits, berries, and bell peppers are excellent sources of vitamin C.

5. Omega-3 Fatty Acids

Omega-3 fatty acids are known for their anti-inflammatory properties and role in nourishing hair follicles. A study published in the Journal of Cosmetic Dermatology found that supplements containing omega-3 and omega-6 fatty acids improved hair density and reduced hair loss.

Incorporating fatty fish, flaxseeds, and walnuts into your diet can provide these essential fatty acids, promoting healthy hair growth.

6. Zinc

Zinc is involved in hair tissue growth and repair and helps maintain the oil glands around hair follicles. A study in the Annals of Dermatology showed that zinc supplementation improved hair growth in individuals with alopecia. Zinc can be found in oysters, beef, and pumpkin seeds, making it an essential nutrient for hair health.

7. Vitamin D

Vitamin D is linked to hair follicle cycling and growth. Low vitamin D levels have been associated with hair loss and alopecia areata. Research in the Journal of Steroid Biochemistry and Molecular Biology suggested that vitamin D receptors are crucial for hair cycle regulation.

Sun exposure and dietary sources like fatty fish and fortified foods can help maintain adequate vitamin D levels.

8. Vitamin E

Vitamin E is an antioxidant that helps prevent oxidative stress in the scalp, promoting hair growth. A Tropical Life Sciences Research journal study found that vitamin E supplementation increased hair count in individuals with hair loss. Avocados, nuts, and seeds are rich in vitamin E, providing a natural way to support hair health.
