What's up bro,
First, that's wassup, if you think you have mastered the basics and want to add some specialty services to your business - I'm for that.
My advice is to make sure your compensated for your time. Charge for the time it takes you to give them that million dollar feeling.
Then, if they would like a black masque, facial, or any other service charge them for your time.
What do I mean by this?
I see barbers raise the price of their cuts, $5-10 dollars and add a whole cut's worth of time in services. Instead of raising the price of just the cut. If you raise your prices, but add supplies and time - you're losing money.
Make sure you're highly skilled.
The point is to be in high demand for the quality of your cuts. Make sure you're compensated for that properly first.
Then you can bring value in other places.
