I'm glad you are at a place now that you are okay with. It's not a battle I'd be willing to pick either.
I love her hair!
My 16 year old daughter has naturally blonde hair but has been wanting to dye it dark brown or black. She has actually done this a few times. I got tired of arguing with her about it and came to a "It's her hair -- what's my problem?" conclusion. The last time she dyed it, it turned a strange orange color, and I took her to the hairdresser who re-dyed it (dark brown) since that's what she wanted.
The thing is -- I think she looks much better blonde. Her eyes are blue and she is fair-skinned, and it just looks much more natural to me.
She is hounding me again -- I want to dye my hair! What would you tell her? Is it me that's being ridiculous? I want her to leave her hair alone.
