For instance I buy a certain line of cosmetics. Last time I was in there they gave me three samples of their newest products with my purchase. I tried one of the samples that same day. It was a facial scrub. I was so impressed with the item that I went back the next day and bought a full size of the product.
How does that not help you as a salon owner. For instance what if you sold teeth whitener. Customers are a bit intimidated about paying for something they are not sure about. Well what if one of the GWP with their lotion was the teeth whitener. Now they can try it. And if they get great results they are going to come back to you and buy that item. Or
moisturizer , or Step 2 Lotion, or legs product. The possibilities are vast!
