Is it weird for a 7 year old boy to want color in his hair?

So my boyfriend and I have been together for a long time and he has 3 kids and I have one all form previous relationship. Recently my 7 year old son asked for color in his hair and I said yes . My boyfriend said it’s odd and I immediately got defensive . He told me he can’t give his opinion without me thinking he’s attacking me . Am I wrong for being defensive or is he right to give his opinion

It’s not weird at all. Its super cool! :slight_smile:
