Question: 1 / 400

Which is a common ingredient found in nail strengthening products?

Vitamin E

Silicone

Keratin

Keratin is a common ingredient found in nail strengthening products because it is a type of protein that is an essential component of both hair and nails. This protein helps to improve the strength and resilience of nails, making them less prone to breakage and splitting. By incorporating keratin into nail care products, manufacturers aim to enhance the structural integrity of the nails and promote healthier growth.

In contrast, while Vitamin E is often included for its moisturizing properties, silicone is primarily used for its smoothing and shine-enhancing effects rather than strengthening. Glycerin, on the other hand, acts as a humectant to draw moisture into the nails but does not specifically provide strength. Therefore, keratin is the most directly associated ingredient with the fortification and strengthening of nails in these products.
