French manicure gradient styles refer to nail designs that feature a smooth, blended transition of colors, typically with a solid color base and a gradient of lighter or darker shades at the tips of the nails. These styles are popular for their elegance and simplicity. They can be enhanced with various techniques, such as using gel polish, nail art pens, or even glitter. For pictures of such styles, one can find them in beauty and fashion magazines, nail art blogs, or social media platforms like Instagram and Pinterest.
