Owing to recent bitter personal experience, it would make me really happy if you were to take heed of the following:
* The customer is always right. Sometimes the customer will ask for something ridiculous, in which case you should explain that it's not a good idea. Other than that, your job is to deliver what they want, not to impose your own tastes upon them. If the customer tells you they want to keep the length, do not then chop off 5cm and feel smug that you've "fixed" their hitherto crappy hair and expect them to be all grateful. Suggestions are very welcome. Just going ahead and doing things without asking is NOT.
* Not everybody spends hours in front of the mirror every morning. Just because I don't, doesn't mean I'm some mad bag lady with seventeen cats who hasn't washed since 1984. There is nothing wrong with me, so don't look so fucking disgusted when I tell you that I hardly ever straighten my hair. Curls rock, and burnt hair smells like ass.
* Don't diss my curls. They are not "stubborn", they do not need to be "corrected", they are beautiful and possibly my best feature. I asked you to straighten my hair just for a change and because it takes me ages to do it myself, not because there is anything wrong with the natural state of my hair.
* Blonde highlights? On almost-black hair? You have GOT to be kidding. Quit suggesting it, it ain't gonna happen.
* Don't insult me. I know that the beauty industry works by convincing women that there's something wrong with them that needs fixing. I know that by persuading me that what I really need is a cut that only looks good straight so that I need to fork out £100 for straighteners and blonde highlights that need retouching every few weeks you will make more money out of me. But you are not seriously going to convince me that there's anything wrong with having dark glossy curls halfway down your back.* Quit trying.
* I do not want to look like everybody else. My hair is probably my most distinguishing feature. I'm not amazingly attractive or striking generally, but my hair sets me apart. I know that long curly hair is not in fashion. But I don't want to look like a fashion victim. Besides, I get more compliments on my hair than anything else, so I must be doing something right.
I hope we can get on better in future. If not, you'll have the straightest arse crack in London considering where I'll shove those GHDs of yours.
Luv n hugz!
*Well, as long as they're not sprouting OUT of your back. Even then, it would be pretty damn rude to say anything about it unless I specifically asked for some waxing
