There are two ways to decide when to buy something. Almost every salon is using one of them without knowing it has a name, and most are using it on the products it does not suit.

A par level restores a shelf to a state you decided once. It is easy to follow and needs no arithmetic, and it has no opinion about how long your supplier takes. A reorder point is built from how much you use during the wait, plus a cushion — which means it moves the moment your supplier gets slower.

This episode runs the numbers on both with real figures and sorts which products belong to which method. It lands on running the two side by side rather than picking one. The hosts split on whether reorder points are rigour or over-engineering for a salon that has never measured its usage rate.

Almost every salon that has tried to get stock under control started with a spreadsheet. Usually built on a Sunday, usually by the owner, after a week that went badly. It works on the day you build it. It starts to drift by about day four.

This episode gives the honest version of a spreadsheet that actually works — one row per product with its wholesale cost, plus the date column almost everyone leaves out. Then it goes to the three points where it stops working: the second pair of hands, the backbar, and the day you are ordering from a dozen suppliers. The hosts disagree about whether building one is a waste of time or a diagnostic worth doing even if you abandon it.

And this is where the software most salons already run stops helping: it records that the number went down. It won't tell you to buy anything.

Every licensed pro learned the safety rules once, in school, from a chapter that was mostly about fire extinguishers. Then you started working, and the real risks turned out to be quieter — a product decanted into a bottle nobody relabeled, a room that ventilates fine in October and not at all in July.

This episode goes through the parts of salon safety that generate incidents rather than the parts that generate paperwork. It covers how professional products are meant to be stored and what happens when they are not, and what a safety data sheet is actually for — a document nobody reads until they need it in a hurry. It also gets to decanting and repackaging, where liability quietly moves onto the person holding the bottle, and to the product expiring at the back of a shelf, which is a safety question before it is a money question.

The hosts disagree about how much of this is genuinely the salon's job and how much has been handed down from manufacturers and regulators to whoever happens to own the room.

Most salons do not know what is on their shelves until something runs out mid-service.

This episode is about why inventory tracking keeps getting skipped, even though it is one of the cheapest problems in a salon to fix. It goes through what running blind actually costs — the stockout in the middle of a colour service, and the product ordered twice because nobody could see the first order sitting in the back. Then it gets to the smallest possible way to start, one that does not turn into a second job by week three.

Your client is on tretinoin, breaking out anyway, and sure she is doing everything right. Often what she has wrong is the order she puts things on in.

This episode settles the tretinoin-and-hyaluronic-acid layering question the way it plays out at the chair. Either order can work, and each one trades something away — the episode says what. It covers how long to wait between steps and why the skin has to be dry first, then the buffer approach for a client whose barrier cannot take tretinoin straight. There is also a consultation script for the client who is certain her dermatologist said otherwise.

"Natural" and "synthetic" vitamins can sit next to each other on your shelf and look identical, with very different price tags. Whether your client's skin can tell them apart is a separate question.

This episode works through natural-derived and lab-made vitamins in professional skincare — what actually changes in bioavailability and stability, and why one vitamin turns up under several names on an ingredient list. It sorts where the source genuinely changes the result from where it is a line on the front of the bottle. For the person who has to answer "is this the natural one?" with a client already in the chair.

Welcome to Backbar Talks — the show that opens the bottles.

Your inventory is leaking somewhere you haven't looked, and the Korean ingredient your med-spa friend keeps texting about is already in someone else's treatment room.

This is the pilot, and it works more like a menu. From here we take one thing at a time, weekly, in 15 to 20 minutes: the economics of pricing, what happens in the back room, the science behind ingredients and protocols, and the trends that reach your supplier emails before anyone says them out loud.

Today we walk the four pillars and tease what's coming — where the money goes between a gross year and what you actually keep, how much of a month disappears into ordering, and why K-beauty wholesale and PDRN are about to change what shows up in US treatment rooms.

For solo estheticians, salon owners, med-spa pros, and anyone who orders product without a purchasing department behind them.
