"Drenched" Hair Colour Is the Grungiest Spring Trend We Never Knew We Needed

The first take on the trend is the opposite of what you see on Billie Eilish: drenched ends. "If you want to go darker on top and funkier on the bottom, ask your colourist to deposit a darker colour on your roots — preferably one that is two or more shades darker than your natural hair," said Schaudt. "This creates depth within the base and complete saturation of the hairline and part. By first adding a deeper pigment you're creating a perfect backdrop for the brighter colour being applied thru the mids and ends."

The secondary colour should be the brighter of the two shades. "If your ends are pre-lightened, you'll paint from the tips up. This colour should marry with the base colour, giving a noticeable meeting point."

Just note: "If your hair is not already pre-lightened, you'll need to first marry the lightener with the base colour."

The second take is to do the exact opposite: "With the next option you flip-flop the two, lightening your natural base colour to at least a yellow blond," she said. (Again, think Billie Eilish here.) "This gives the option to use more unnatural colours emphasising the body of your hair. This brighter tone is toward the roots and the more muted tones are on the ends. Again these two colours should marry in the middle."
