Your hair is a reflection of your overall health—and what you eat plays a huge role in how it looks, feels, and grows. While shampoos and serums matter, true hair vitality starts from within.
At RxRejuvenate, we help our clients understand that nutritional support is a key pillar of hair restoration. Here’s a closer look at how your diet affects your hair—and what nutrients you need for stronger, healthier strands.
Why Nutrition Matters for Hair
Hair is made primarily of keratin, a protein that requires a steady supply of nutrients to grow. When your body is deficient in certain vitamins and minerals, it diverts resources away from “non-essential” functions like hair growth to support vital organs. The result? Shedding, thinning, and brittle hair.
Key Nutrients for Hair Growth
1. Protein
Hair is 90% protein—so low protein intake can lead to weak, slow-growing strands.
-
Sources: Eggs, lean meats, legumes, tofu, dairy, quinoa
2. Iron
Iron deficiency is one of the leading causes of hair loss, especially in women.
-
Sources: Spinach, red meat, lentils, pumpkin seeds, fortified cereals
3. Zinc
Zinc helps with tissue repair and keeps oil glands around follicles working properly.
-
Sources: Nuts, shellfish, whole grains, dairy
4. Biotin (Vitamin B7)
Biotin supports keratin infrastructure and is vital for thick, healthy hair.
-
Sources: Eggs, almonds, sweet potatoes, salmon, bananas
5. Vitamin D
Low levels of vitamin D are linked to alopecia and general hair shedding.
-
Sources: Sunlight, fatty fish, fortified dairy, egg yolks
6. Omega-3 Fatty Acids
These nourish the scalp and help keep hair shiny and hydrated.
-
Sources: Chia seeds, walnuts, flaxseeds, salmon, sardines
Signs Your Hair May Be Lacking Nutrients
-
Increased hair shedding or slow regrowth
-
Dull, dry, or brittle hair
-
Thinning at the crown or temples
