Blue hair for my 9 year old?

[Kentuki]

DS has said he wants blue hair over the summer. I can’t see an issue, it will all be grown out by September or can be shaved off if necessary.

I generally try to live by “say yes to whatever you can, but when you say no, mean it”.

DH isn’t keen as he sort of kicks against anything unexpected like this, but essentially he will let me decide (and he will be the one doing the dye job).

It’s fine isn’t it? I’m not missing anything but saying go ahead?

Yabu - no blue hair
Yanbu - blue hair summer

I'd say whatever colour hair over summer is fine - he won't be in school so what's the problem. I died my son's hair orange over summer once - he loved it!
