Blue on ginger

My hair colour originally is the same as my son’s but now I’m pink. I’ve had it pink for a couple of years now but my boy was insistent that he wanted ‘blue’ hair.
This, when washed out tomorrow, will be green! It’s sooooooo gonna stain his hair and scalp but when yer boy has autism, ye choose yer battles and as a mother with dyed hair I can’t really say no!
I just want to shave it all off tho. He loves it, he’s happy, and it will be shaved off by the end of next week anyway but still...... things we do while finding our identity eh
