When it comes to mobile hairdressers, whilst I know that there is travel time etc involved, there are no overheads like the salon rent, electricity etc.
You would be using your client's electricity etc so this is why I believe it should be cheaper.

Ladies Style Cut? Probably around $20

Mens Style Cut? $17

Pre-School Cut?$10 - I am shocked at the pries hairdressers charge for this!

Primary Cut? $15

Secondary Cut?$15

"Family Cut Package" - say 2 adults and 2 kids? $40-45

Also what would you pay for a Colour at home? Depends on the length of hair of course - I have med length hair and I would say $50 would be my max

What would you pay for a straight Tint?Not sure on the price of this normally so I'm not sure
What would you pay for a half head of foils????Again, for med length no more than $50

I hope this helps you.
