Can you just use conditioner? I used so many bloomin' containers of the smelly stuff.
At the risk of making your stomach hurt - here's another tale of me and "hair".
I finished doing henna on my hair when I was o.s. in my early 20s, and then in the dead of night realised that it was Mother's Day in Australia.
I dashed out to the phone box to make the call....
My mother then informed me that I was a week early - it was
next Sunday.
I said "Mum, I am standing in a well lit public phone box in the middle of London with a plastic shopping bag on my head, looking like Marge Simpson"..... "and you mean to tell me, it's NOT Mother's Day?"

And, in Morocco I regularly used to go into cafes wearing a black plastic sleeping bag cover (with handy draw string) on my head, covering henna. Of course, in Morocco - nobody bats an eyelash.
By the way, black leggings don't suit me.
