Ah the clue is in your post, you were happy when you left the salon, it seems that it is the way that you style it yourself is what you are not happy with, not the cut, some salons offer a styling teaching session to show you how to achieve the result somewhat near to that which the stylist was able to, I say somewhat near because they are professionals with many years of experience, whereas you are not. I would suggest that you return to the salon when you have just done your hair to show him how you are not managing to achieve the same look, it could be that he takes one look at it and knows immediatedly where you are going wrong , I would also suggest don't chose a Saturday to do this it is a hairdressers busiest day and he is less likely to have the time to chat with you.
