Set a timer. Do not “just check Instagram for five minutes.” That’s how people end up with neon orange hair that screams “I was in a lab accident.” Follow the time on the box as if it’s a bomb timer.
If your scalp starts tingling, that’s normal. If it starts screaming, rinse immediately. Hair dye is not some medieval torture device, but it can feel like one if you’re allergic. Always do a patch test 48 hours before. Yes, you probably won’t. But now you can’t say I didn’t warn you.
Surprising fact: gray hair is stubborn because it lacks pigment cuticle. It’s like trying to dye a piece of Teflon. So if you’re covering grays, add 5–10 extra minutes to your timer.
