The thing a salon gets sued over

No colour bookswithout its test.

The page books the test with the colour, or checks the one the salon already holds.

48 hours before a colour
A clear test counts six months
Both visits booked together, the test first
Done, clear — or a reaction
Somebody who reacted is asked to call, never told why

A colour is never one thing

A colour, its tonerand the cut after it.

One appointment, with one length and one price, and one stylist who can do all of it.

Offered under the service they go with
Never on the menu alone
2 hrs 20 min, £133, one chair
Untick the colour and its add-ons go
A junior who cuts is not offered a colour

Saturday, from the front desk

Five columns,thirty-one chairs.

Each appointment as long as it takes, in its stylist's colour, with nothing double-booked.

The day, or the week
A sheet for every appointment
A client's visits, behind and ahead
Vouchers sold, spent and still owed
Reports, down to a CSV

Stylists, between two clients

One press,and the colour stops waiting.

A test written down from the chair clears the colour it was booked for, there and then.

Android and iPhone, one codebase
Who is next, and what they are having
Where a colour's client stands
A quick booking, add-ons included
