Which statement is true regarding the keratin found in natural nails compared to hair?

• A. The keratin in natural nails is softer than the keratin in hair
• B. The keratin in natural nails is harder than the keratin in hair
• C. Both types of keratin are identical in softness
• D. The keratin in natural nails and hair are of the same strength

Answer: (A)

The statement that the keratin in natural nails is harder than the keratin in hair is accurate. Keratin is a fibrous protein that comes in various forms depending on its location in the body and function. The keratin found in nails is made up of tightly packed, durable cells, which gives nails their rigidity and strength. This hardness allows nails to protect the sensitive tips of fingers and toes while also providing support for gripping. In contrast, the keratin in hair is arranged in a different structure, which gives it more flexibility and softness compared to the keratin in nails. Hair is designed to be more pliable, allowing it to withstand bending and styling without breaking easily. The differences in the structure and function of these two keratin types highlight why nails are harder and more protective than hair, which serves different purposes.
