What are the limits? lol Haircuts arnt big deals....like I said, hair grows back....color washes out. Its nothing permanent and no harm is done.
I will NOT allow my children to permanently dye their hair a Godawful color,pierce their bodies,NO pierced ears on boys,no tats until they are 18.
My limits are well known by my kids.They know what they can and can't do.
As far as "it's only hair", yes it is.BUT, I wouldn't be caught out in public looking like that, nor would my kids.
If you can't go like that to Church, or to something formal, then you shouldn't have it in the first place.
