Is it a big deal if your crush notices that you dyed your hair?

I last saw my crush on Friday at work, and on Saturday I had my hair coloured. Nothing drastic, just a wee bit darker. I am a brunette and I went a shade or so darker.
I put a post up on my Instagram about it, more so to show off how much it has grown and how lovely it looks. Me and my crush are following each other on Instagram.

I saw him today at work, and he looked at me and then said, “have you dyed your hair?”

And then I said “yeah, do you like it?” to which he said “yeah”

Is it a big deal? I am under the assumption that guys don’t tend to notice or comment on these sorts of things unless they are attracted to the girl

Yeah he has a crush on you
Doesn’t mean anything
