This is just something that takes time and being repeated for you to feel comfortable. The same as talking to your client about home hair care.
When you're at the front desk taking payment it should be automatic to ask if they'd like to make their next appointment. I just say "would you like to book your next appointment?". Most people mean to and forget, so it's a friendly reminder for those clients who done have their next four appointments sorted already. I also make it ok for my clients to not rebook with a friendly smile I say "That's ok, here's my card so you have our number when you're ready"
These habits should also apply to selling retail. I make a habit when I use products to sit the bottle on the bench in front of them. I tell them what it is, why I'm using it and the finish it will give to the hair. I say nothing about them buying it or why they should have it at home. I relate it all back to what I am doing with their hair. Then they have a chance to ask questions and smell it etc. I sell a lot of retail this way.
Rebooking, upselling, and selling retail are a huge part of earning good money and ensuring your future business. Don't think of it as pestering your client - and don't approach any of these things from the perspective of making a sale or improving statistics. It's about caring for your client and their needs.
I hope that helps.
