7 Foods to Increase Keratin Levels
Keratin is a structural protein that builds hair, nails, and skin. After bariatric surgery, keratin and protein levels can drop, leading to hair loss. These foods help:
1. Eggs
Eggs are rich in biotin and sulfur — both important for keratin synthesis. 1–2 eggs daily are ideal.
2. Salmon and Fatty Fish
Omega-3 fatty acids and high-quality protein support hair health and keratin production.
3. Sunflower Seeds
Rich in biotin, zinc, and vitamin E — essential nutrients for keratin.
4. Sweet Potatoes
Contain beta-carotene, which is converted to vitamin A — essential for keratin synthesis.
5. Chicken
High protein content and cysteine (amino acid) are direct building blocks for keratin.
6. Onions
Contain quercetin and sulfur compounds that boost keratin production.
7. Mangoes
Rich in vitamins A and C — both promote keratin production and protect hair from damage.
Hair Loss After Bariatric Surgery
Temporary hair loss (telogen effluvium) is common after sleeve gastrectomy or gastric bypass surgery. With adequate protein, biotin, and zinc, hair typically returns to normal after 3–6 months.
