Addons for different shampooer, cups of coffee, etc etc. There are some establishments now that just cut hair, no washing, no frills, no appointment (like gents). Walk in sit and wait, say what you want, they spray mist your hair then cut. Trim will cost about �14-15, restyling �18. Men use the same place and will pay about �12 for scissor cut and �10 for a razor cut.
I've used one now for over a year, the hairdressers are expert in their profession. Never will I go to an 'ordinary' one again.
Must all be due to their overheads (pardon the pun), basins, water, etc etc.
