Protein: The Building Block of Healthy Hair
Just like our bodies, our hair is composed of proteins. Keratin is the primary protein found in hair, accounting for around 90% of its structure. This fibrous protein forms the cortex, the inner layer of the hair shaft, providing strength, elasticity, and protection.
Why Protein Matters for Hair
- Structural Support: Protein strengthens the hair shaft, reducing breakage and split ends.
- Elasticity and Bounce: Healthy protein levels give hair the ability to stretch and recoil, preventing damage from styling and environmental stress.
- Moisture Retention: Protein seals in moisture, keeping hair hydrated and preventing dryness and frizz.
- Damage Resistance: Protein fortifies the hair’s protective layer, making it less susceptible to UV rays, heat styling, and chemical treatments.
Benefits of Protein for Hair
- Stronger, Healthier Hair: Protein repairs and strengthens damaged hair, promoting overall hair health.
- Reduced Breakage and Split Ends: Adequate protein prevents hair from snapping or splitting, giving you longer, thicker-looking hair.
- Improved Curl Definition: Protein helps define curls, reducing frizz and enhancing their natural shape.
- Increased Shine: Healthy protein gives hair a glossy, vibrant appearance.
- Reduced Hair Loss: Strong hair is less likely to fall out, reducing shedding and hair loss.
