Prof. William Dalton, Ph.D.The internal nutrition of the hair is extremely important to its strength. Keratin proteins are the structural basis of the hair. Iron carries oxygen to the hair follicles. Zinc regulates the oil supply. Vitamins A, C, D, and E help maintain hair strands by protecting them against daily damage. The nutrients have a synergistic effect, like a construction crew building strong strands.
Protein Powerhouses
- Keratin formation: Amino acids from eggs and fish build hair structure
- Collagen support: Chicken and beans provide cysteine for flexibility
- Repair mechanisms: Lentils supply methionine to mend damaged strands
- Daily requirement: 50g minimum for medium-length hair maintenance
Vitamin Protectors
- Vitamin A: Sweet potatoes regulate sebum production naturally
- Vitamin C: Bell peppers boost collagen for follicle integrity
- Vitamin D: Sunlight exposure activates growth receptors
- Vitamin E: Almonds shield against environmental oxidative damage
Mineral Regulators
- Iron transport: Spinach carries oxygen to roots efficiently
- Zinc balance: Oysters control oil gland functionality
- Selenium defense: Brazil nuts protect against UV degradation
- Copper activation: Mushrooms help pigment formation
It's about food synergy, rather than isolated nutrients. Pair plant foods high in iron (spinach) with those high in vitamin C, such as peppers, for better absorption. Pair plant proteins, such as rice and beans, to provide all the essential amino acids needed. Clients see faster results with combined foods than with expensive supplements.
Timing the intake of nutrients can affect hair growth cycles. Eat protein one hour after washing hair to facilitate repairs. Eat vitamin C-containing foods before sun exposure. I schedule dinners during the week after showers in the evening, which promotes the regrowth of thin areas after pregnancy.
Consistency is a grantor of change. Clients like Mark reversed his hair loss by consuming nutrient-dense foods at meals for six months. His breakfasts of smoothies made from spinach and berries increased his iron levels. Snacks of walnuts helped keep his omega-3 levels up. A gradual change is often preferable to a quick fix.
