My mum's a beautician, so I practically half grew up in a salon.
This resulted in me hating everything about what goes on in there .... but that's a different story. But I can, at least, wax my own leg perfectly :)
At 14 i had very long , very dark brown hair, ended somewhere under my ass. I used to sit on it and it would pull, so one day from school to home i dropped into a hairdressing salon and got it chopped to about 3 centimeters long. And if I was there already had it colored (permanent) to bright red.
Got home, knocked, mum opened the door said fuck it and closed the door in my face :) It took 3 more tries to get in.
I have dyed my hair for the past 30 years at home, but almost always with professional colors (from my mum). One time I wanted a quick touch up before going on holiday, so went into shop, bought a nice bright red color - it said permanent.
- It turned my hair pink. God knows why.... But it was about 2 cm long, so I didn't really care, it'll grow out fast enough.
- Next day went into the swimming pool on holiday (remember: permanent...) and ended up with nice bright red streaks in the water. The manager accused me of going in whilst having the period without a tampon. I had to prove multiple times that the red came from my pink extra short hair.
Never figured out what happened.
Hate sunbeds, used them a few times as a teen. Few years ago had to work all summer,no hols and thought I'd treat myself to a tan. Unbeknownst to me I had developed some weird thing that if i don't put sun blocking cream above my upper lip it'll get much darker fast. So ended up with a nice mustache for 2 years.
