My question is about the correct way to set up the system for a hairdressers / hair salon.

Ie. Haircut, styling, washing are separate items that the customer would want to book. Then also in a salon there are also 2 - 3 different hairstylist working.
Do I create a different template for each​ Haircut, styling, wash then create the worker as the bookable item?
Or do I create a bookable item for each Haircut, styling, wash and make the stylist the template?

If someone books a haircut from one of the stylists that time slot needs to be unavailable across the other calendars for styling, washing etc. so that they don't get double booked for two different services.
Please help.

Hello, I would create item for each hairstylist and services like haircut or washing should be supplements.

Hi,
I tried what you said but am still having difficulties.The issue is that each of the supplements has different timing and price associated with it, for example:

Haircut - 60 min (55eur)
Colouring - 90min (100eur)
Colouring with streaks - 120min ( 1500 eur)
Styling - 30min ( 27eur)
cut and colour and styling - 180min (150eur)

Setting the price for each of them is no problem.

The problem is that the bookable object ( or hair stylist) has set slots of 30min or 1 hour. If someone books the hairstylist for a colouring then that means 3 adjacent half hour slots need to be disabled but as it is now, it will only book one half-hour slot unless the end user manually books 3 adjacent time slots.

Any other thoughts or suggestions please?
