Biotin is a well-known ingredient commonly included in nail strengthening products due to its role in promoting healthy nail growth and strength. It is a vitamin that falls under the B-complex group and is crucial for the metabolism of proteins and fats, which are essential for maintaining healthy nails. Biotin helps improve the keratin structure of nails, making them less prone to splitting and breaking.

In contrast, while Vitamin C plays a vital role in collagen production and overall skin health, it is not specifically targeted for nail strength. Castor oil, while beneficial for moisturizing and nourishing the nails, does not contain specific compounds that strengthen them. Petroleum jelly acts primarily as a barrier to retain moisture but lacks any strengthening properties for the nails. This makes biotin the ideal choice for those seeking to enhance their nail strength effectively.
