This is a great site to check out if you are tight on money but need a fabulous haircut, blowout, or color. Training apprentices will post an ad looking for volunteers every week. Each ad is only posted for 7 days, so all listings are very current. It has sections for New York, Los Angelas, San Francisco, Chicago, London, and Sydney. Just click on the city closest to you to find an apprentice, and get a sweet ass style (for free or low cost). All services are overlooked by a master stylist so no need to worry.
ps: you can even post a model profile and let the apprentices look for you!
