OK not literally, but you can send your knowledge and the right products home with each client. Back when I was in the salon, we didn't have the product choices we have today. Products are your wardrobe of opportunity—choose the right one to dress your client's individual style.
Clients get frustrated when they can't recreate a great salon style at home, and choosing just one product from a wall of products can be overwhelming. Save your clients from wasted time and money by sending them home with the right products. They'll be happy and they'll look great.
Try it: Suggest a product to every client for the next month. You end up with happy clients and more money in your paycheck.
