As mentioned by Life in a Breakdown, nail art as a form of self-expression became especially popular during the COVID-19 lockdown, as everyone was looking for new ways to express their style and pass the time. For a personality type that is especially creative and expressive, this makes artistic nail art designs perfect for Enneagram Fours (per Picture Polish). Though it may be trendy now, Inklings News predicts that the customization and versatility of nail art designs will make this a lasting fashion and beauty trend.

Bright swirling patterns or customized French manicures are trendy looks mentioned by Refinery29 that are especially suited to the personality of the Enneagram Four. The French manicure is a classic look, but embellishing it with different colors, jewels, and designs makes it a great outlet for expressing the individualism of the Four. And the bright, wavy colors of trending swirling patterns are sure to make any color combination look unique, making it another look fitting for this personality type.
