Haircuts, yes!
My mum's best friend was a hairdresser but she only seemed capable of doing one type of cut (short perm favoured by 1980s women over 35).
When I was about 12 or 13 my mum persuaded me to "do something " with my very long very straight hair (which I quite liked btw).
I liked the idea of some soft long layers and a layered fringe to try and give it a bit of body and movement. I explained all this, hairdresser nodded along and then cut it all off short in a "Lady Diana " style which i hated!!!
Worse still she contacted my mum a few months later to say it would need trimming. I protested as I desperately wanted to grow it out but mum said I would hurt her friend's feelings if I said no. So I was shorn again. I had quite a "grown up" face despite my age and it made me look like, well, a middle aged housewife! Even the hairdresser's son (same age as me) whispered in horror afterwards "its awful isn't it?".
That was not the end ... Next time mum persuaded me that it would look better if I had it permed as well. I was not convinced and sure enough I looked like I was wearing one of those scouse wigs! I utterly refused to have my hair cut again snd as soon as it was long enough I scraped it back into a tiny ponytail to hide the horror.
Not long after this she gave my sister a pixie cut that made her look like a 10 year old boy! That was the last time she cut her hair too!
Nice lady but fucking awful hairdresser!
I'm now 47 and have very long very straight hair. Anything else seems traumatic!
