Cheap services by hair stylists that have graduated from beauty school and usually have worked other places. They are typically "auditioning" for the high end salons. They need models for all kind of services. They offer it on the cheap to come and be their model. www.salonapprentice.com
I used this like 4 years ago for 2 years for cheap hair services. I actually found my regular girl on this site that I love and now pay an arm and a leg for. I have tried salon buzz, mixedco, red 7 salon, sine qua non, Mario tricocci, goran coban, etc. I went to Studio 110 for over a year on their apprentice hair program. anyway, some of the services are free. Typically these are people that are pretty new. The ones that are discounted are usually seasoned people. Either way, I have never had a bad experience BUT I only have gotten highlights, trim, etc.
Use above link & get $10 off first service.
This site is like groupon but for beauty, fitness, etc. they have two parts.
Lifebooker Loots which are similar to a groupon. You buy it and then call, make your apptmt, etc
Lifebooker option is to book directly online so you don't have to worry about calling and making an apptmt.
They have some really good deals on stuff. Overall, most of the services I have used on here have been good. A few lemons
Another online booking site that I use now pretty frequently is
Use above link & get $10 off your first booking. This site has nails, hair, massage, etc. great selection of places. They also have some deals..."off peak pricing" etc.
Another website/app I use for on the go beauty is Whittl. Below is a code for $20 off your first service. I usually just book my nail services (jasmine nails in the loop) through them but they have everything.
