Which Hair Colour Is Most Damaging? The Truth No One Tells You

The Most Damaging Hair Colours: Let’s Get Real
You ever stood in the drugstore aisle, box dye in hand, and wondered, “Am I about to totally fry my hair?” Last week, my friend Jess and I got into a heated debate about which hair colour causes the most damage. Spoiler: I was wrong (and my hair paid the price a few years back, yikes).

What Makes Some Hair Colours More Damaging?
It’s not just about the shade. Nope. The science is wild.
— Permanent vs. Semi-Permanent: Permanent hair dyes use ammonia and peroxide. That combo lifts your cuticle, strips your natural pigment, and lets the new colour in. This process is harsh. Semi-permanent is way gentler, but also fades faster (which is a bummer when you finally love the colour).
— Going Lighter vs. Going Darker: Here’s where I got it twisted. I always thought any dye hurts, but bleaching (hello, platinum!) is in a league of its own. The lighter you want to go, the more damage you risk.
One time, I tried going from dark brown to icy blonde in one weekend. Big mistake. My hair felt like straw, literally—my brush would just… get stuck. Should’ve listened to Jess.

Why Blonde (Especially Platinum) Is the Most Damaging
If you’re dreaming of that bleach-blonde look, brace yourself.
— Bleach strips away everything—pigment, protein, even moisture. It leaves the hair super porous and fragile. That’s why you see so many split ends on blondes who bleach a lot.
— Multiple sessions make it worse. You might think you’ll get that perfect blonde in one go, but most stylists (the honest ones, at least) will warn you: it takes time and patience if you want to keep your hair on your head.
Jess told me about her cousin Emma, who tried a full bleach job at home. Her hair literally snapped off in clumps. Honestly, I felt secondhand panic just hearing that story.

Are Red and Black Dyes Also Damaging?
Red dyes can be rough too, especially if you have to lighten your hair first to get that vibrant shade. The thing about red: it fades fast, so people end up colouring more often—hello, repeated damage.
Black dye doesn’t usually require bleaching (unless you’re super light), but getting rid of black once it’s in? Oh boy, that’s a whole other nightmare. Removing black can involve even more bleach and chemicals than going blonde in the first place.
Funny thing: I once dyed my hair jet black on a dare. Looked cool, but months later, I wanted to go light again and… let’s just say, I wore hats a lot.

How to Minimize Damage—Even if You Love Colour
— Use deep conditioning masks, like, religiously.
— Don’t wash your hair every day (dry shampoo is a lifesaver).
— Always, always listen to a professional—YouTube videos only get you so far (I learned that the embarrassing way).
Honestly, sometimes it’s better to just embrace your roots for a bit and give your hair a break.
Jess and I still laugh about my straw-hair phase, but trust me, nobody wants to go through that twice.

Final Thoughts: Changing My Mind About Colour
Okay, real talk: I used to think “hair is just hair.” Now? I realize every box of bleach is basically a box of risk. Out of all hair colours, going blonde—especially platinum—is definitely the most damaging. But reds and jet blacks have their traps too.
Still, I get it—the confidence boost from a new colour is unbeatable. Just, you know, treat your hair with some love after all the experimenting. And hey, if you ever need to hear another hair disaster story before you dye, hit me up. I’ve got plenty.
