Not all colors are created equal. Red and purple are the needy exes of the dye world. They demand more time—up to 45 minutes—to really sink in and be dramatic about it.
But pastel pink or lavender? Those are the chill, minimalist friends. They only need 10–20 minutes to whisper a hint of color. Overdo it, and you’ll end up looking like a highlighter that got caught in the rain.
The Bottle Often Lies (Kinda)
Yes, the instructions on the box say “Leave on for 20 minutes.” That’s fine if you’re a robot. But you’re a human with unique hair dreams. Treat that time as a starting point, not a gospel.
Pro tip: Do a strand test first. Snip a tiny bit of hair from your brush (gross, but necessary). Clean it, dye it, and watch it like a hawk. This trick saves you from looking like a radioactive clown.
