It depends on what you mean by “nails like that.” If you’re referring to a person with unusually long, decorated, or distinctive fingernails, there isn’t a special name for the person. They might be called:
- A nail enthusiast — someone who enjoys nail art or nail styling
- A nail artist/client — if referring to someone who gets professional nail designs
- Someone with long nails / acrylic nails / artificial nails — depending on the style
If you mean a specific type of nails (for example very long nails, claw-like nails, dirty nails, painted designs, or a photo you saw), describe them or upload an image and I can help identify the style or term.
