Retail Attachment (Retail-to-Service Ratio)

Retail attachment, often measured as a retail-to-service ratio, tracks how much take-home product clients buy compared with what they spend on services. If a client spends $100 on a service and $20 on shampoo to maintain it, that is a 20% retail-to-service ratio. It matters far more than its size suggests because of margin: professional retail products earn about 50% margin versus roughly 8% on services, so retail is where a large share of real profit hides.

Most salons underperform here despite the opportunity. Product costs already consume 8% to 12% of revenue as backbar and retail inventory combined, so you are carrying the stock regardless; the question is whether it sells at 50% margin or sits on a shelf. Selling the products clients are already going home to buy elsewhere directly raises your Average Ticket and, through it, Client Lifetime Value (CLV). It also deepens results, which supports Client Retention Rate because clients whose color lasts come back happier.

Because retail commission is nearly universal (93% of owners pay it on top of service commission), the incentive to recommend product is already aligned with staff pay. Make attachment routine with retail and payments tools that surface the right product at checkout, and track it per stylist in your client CRM.
