Yes I think you can charge more....I am not sure where you live, it is nice to be sensitive to people's wallets, but be sensitive to yours. You deserve to be paid, and for the time you invested, the experience and education.
Are you the owner of your own salon?? I know increasing the prices is better done in small increments.
How much time are you spending on your haircuts? In my opinion blow-outs should be at least 25-40 dollars on their own. It is an art all to itself, and alot of work. At the salon that I am at we charge 70 for the haircut, it includes the blow-dry. (40 for the haircut-30 for the blow-dry) We spend anywhere from 1/2 hour to an hour depending on the client, and the haircuts usually last them 3-4 months.
Don't be afraid to charge more, it's ok.
