Myth #2: Applying gelatin, or nail polishes that contain hardening ingredients, makes your nails stronger.

Truth: Polishes with these ingredients can indeed make nails less vulnerable to splitting, they also make nails stiffer and less flexible – which means they’re more likely to break when exposed to a sharp, sudden impact.

Although many people attribute the strength of their nails to regular immersions in gelatin, this claim has not been investigated scientifically.
