Tipping hairdressers for idiots

[catkind]

OK, I've never figured this one out.

I get that you're supposed to tip.

What I don't get is how much and just how. As in when do I do it, who do I give it to, what do I say? And if I get a £30-40 wash and cut at a salon, how much tip?

Other option is a home hairdresser, they charge less does that mean you tip more or less or not at all as they keep all the money and can charge what they like in the first place?

I've been getting my hair cut at the kids hairdressers with the kids and just telling them to keep the change, and I'm not sure if that's even right - sometimes they've pressed me to take it anyway. Thinking I'd like to get a proper grown up cut now and I don't want to offend. Help oh wise ones!

I tip a few pounds depending on how much cash I have in my purse and am always slightly embaressed by this convention. I assumed everyone tipped, and thought I was a miser. Now I've discovered that lots of people don't tip.

I tip £10-15 every time, at the till rather than to each person.

I used to feel sorry for the apprentices (in any job) as the wage was so low. But then a colleague pointed out when we were training we got nothing and had to get a weekend and evening job so it put it in to perspective

Saying that, I used to tip but now I do the mumsnet haircut so buy myself nice things instead!
