If you’re dreaming of longer, shinier, and stronger hair, it’s time to look beyond your shampoo bottle and into your plate. Keratin, the structural protein that makes up your hair, nails, and skin, plays a vital role in maintaining hair strength and resilience. While keratin treatments are popular, the real magic happens when you nourish your body from within. These seven foods are scientifically proven to naturally boost keratin production and support healthy hair growth.
🍳 1. Eggs – The Biotin-Packed Powerhouse
Eggs are one of the richest sources of biotin, a B-vitamin essential for keratin synthesis. A single cooked egg provides around 33% of your daily biotin needs. Additionally, eggs are loaded with high-quality protein, which is the building block of keratin.
