Weigh what is left in the bowl and SalonScale prices it. Overmixing shows up as a number you can actually do something about.

Finished the service with product still in the bowl? Put it back on the scale before you rinse it. SalonScale records the grams as waste and prices them.
It takes one step, and it is the only way to know what a bowl really cost you.

When you log the leftover, SalonScale knows the bowl was overmixed. Pull that formula up on the next visit and it suggests the smaller amount you actually used.
Every remix gets a little closer to right, so the waste shrinks on its own instead of waiting for someone to notice it in a report.

Waste rolls up by stylist, by service, and by product line, so you can see whether it is one habit, one service type, or one expensive lightener.
Compare weeks and months to check that a change you made actually stuck.

It is one weigh at the end of the bowl, the same motion as any other. Most stylists add it to their rinse routine within a week.
Any product left over in the bowl, meaning it was mixed but not used. Product still sitting in the tube is inventory, not waste.
Yes. Waste reports break down by stylist, service, and product line, and can be compared week over week or month over month.
Most salons start somewhere between 10 and 20 percent of what they mix, and land in the single digits once they can see it. Your own first month is the benchmark that matters.
Yes. Product that was mixed is drawn down from stock whether it went on the head or into the bin, so your counts stay accurate.
