Great hair, skin and nails start from the inside. No cream can replace the raw materials your body needs to build strong keratin, resilient collagen and a healthy skin barrier.
The non-negotiables
Protein, zinc, biotin, iron and omega-3 fatty acids are the foundation. Deficiencies in any of these show up first in your hair and nails — often long before other symptoms appear.
Where superfoods help
Nutrient-dense blends fill the gaps that even a good diet can miss, especially for busy people, plant-based eaters and anyone under stress.
Give it 90 days
Hair grows about 1 cm per month. That means visible results from any nutritional change take at least three months — anyone promising faster is selling you hope, not science.
Frequently asked
Questions & answers
- Do hair growth supplements actually work?
- They work when they address a genuine nutrient gap — most often iron, zinc, biotin or protein. If your diet already covers these, expect subtle rather than dramatic changes.
- How long before I see results?
- Give any hair, skin or nail supplement a full 90 days. Hair grows roughly 1 cm per month, so shorter trials rarely reflect the real effect.
- Are collagen supplements worth it?
- Hydrolysed collagen peptides have solid evidence for skin elasticity and hydration at 5–10 g per day. Look for products that list the exact peptide dose, not proprietary blends.
