3-month grown-out roots to deep black dye: Gangnam salon Beorn Hair
Beorn Hair Cheongdam is a hair salon near Gangnam-gu Office Station in Cheongdam-dong, Seoul. After three months in the US without a root touch-up, the writer skipped her usual ash brown and went for a deep all-over black dye instead. Her hair stayed soft and undamaged for days afterward, making this a solid pick for color that doesn't wreck your hair.
