Compared to hair, how would you describe the keratin in natural nails?

The keratin found in natural nails is indeed stronger compared to that in hair. This is primarily due to its structural composition and the way it is bonded. Nail keratin, known as alpha-keratin, is organized in a denser arrangement, making nails more robust and resilient against physical stress and damage. The strength of nail keratin is crucial for protecting the tips of fingers and toes from injury.

In contrast, the keratin in hair is designed for flexibility and softness to accommodate styles and movement, which makes it less durable than nail keratin. The structural differences also mean that the nails can withstand greater forces without breaking, whereas hair is more prone to damage from environmental factors. This understanding of keratin differences highlights the unique protective functions that nails serve, differentiating them from hair in terms of strength and durability.
