Diet and hair loss — what you eat and how it affects your hair

Hair grows out of one of the body's most active organs, and it needs nutrition to function. When the body falls into a deficiency, hair is often the first to be deprioritised. That means diet is rarely the whole explanation for hair loss — but it can be an important piece of the puzzle, especially in cases of diffuse thinning and slow regrowth. Nutrients that matter Hair is mostly made of the protein keratin, so a sufficient protein intake is fundamental. Beyond that, some nutrients are particularly linked to hair health: - Iron: deficiency is one of the most common causes of hair loss, especially in women. - Vitamin D: supports the follicles' growth cycle. - Zinc: important for follicle function and repair. - B vitamins (biotin, B12): contribute to normal hair structure. - Omega-3: supports a healthy scalp. What a hair-friendly diet contains A varied diet with enough protein (eggs, fish, legumes, meat), leafy greens, nuts and seeds, oily fish and colourful vegetables covers most of the hair's needs. You rarely need special products — breadth and balance matter more than individual "superfoods". Be careful with crash diets One of the most common hidden causes of hair loss is severe weight loss and extreme diets. When the body suddenly gets too little energy and nutrition, a large proportion of follicles can enter the resting phase, causing diffuse loss a couple of months later. This is usually temporary and reverses once the diet normalises. Supplements — only for an actual deficiency Hair vitamins are heavily marketed, but mainly have an effect if you actually have a deficiency. If your levels are normal, extra supplements rarely make a difference, and some substances can be harmful in high doses. Rather take a blood test and address what is actually missing. Conclusion A good diet does not stop hereditary hair loss — that is governed by hormones and genes and requires PRP, medication or a transplant. But the right nutrition gives the hair the best possible conditions and can reverse hair loss caused by a deficiency.
