There's a version of this question that shows up in the inbox at least once a week, dressed up in different words but always meaning the same thing: is there a cut-off point where bright hair stops being allowed?
Short answer: no. Longer answer: The question itself is doing a lot of unnecessary work.
I started dying my hair at 11, and me at at 36 still is.
Where does the idea even come from?
Nobody hands out a rulebook at eighteen that says colourful hair expires at thirty, or forty, or whenever "acting your age" is supposed to kick in. It's more that certain images get repeated so often — young people with pink hair, "sensible" adults with natural tones — that a pattern starts to feel like a rule. It isn't one. It's just what's been shown the most, not what's actually true.
Walk down any high street and the range of people wearing colour tells a different story than the stereotype does. Fifty-somethings with silver-lilac blends. Grandmothers with a streak of cherry red who decided, quite reasonably, that they'd earned it. The "rule" was never real — it was just underrepresented.
What's actually being asked?
Underneath "am I too old for this," there's usually a different question: will people think it's odd, will it clash with how I'm perceived at work or by family, will I regret drawing attention to myself. Those are fair things to wonder about. But they're questions about other people's opinions, not about hair, and definitely not about age.
And here's the useful bit specific to semi-permanent colour: because it fades out over a few weeks, "will I regret this" has a built-in expiry date. Even in the unlikely event that colour draws a raised eyebrow from someone who wasn't consulted, that eyebrow only has a few weeks to be raised before the whole thing washes back to normal.
Age isn't the deciding factor. Curiosity is.
The people who end up loving a colour change usually aren't the youngest in the room — they're the ones who got curious enough to stop asking permission and just tried it. That curiosity doesn't come with an age limit either.
If the question "am I too old for this" has been rattling around for a while, that's usually a sign the real answer is already known. It's just waiting for someone to say it out loud.
