For the last 8 years I've been getting my hair cut by a friend with a clippers and the attachments. However I'm looking for something new and want to try out getting my hair cut by a professional with a scissors so I don't get such frizzed hair. Anywho, the only place I've ever heard of around here (East Bay, CA) is Supercuts. Are they any good? Also what is the deal with tipping the person who cuts your hair? What is the going rate for a tip and do I have to tip? TIA
