I still haven't exactly found a book. I went everywhere looking for a book on cosmetologist and how they do their work, but all I could find were manuals and books on how to pick the right school. Hopefully i can find one soon cause lord knows i need these points, but I don't know maybe i can find one while im in Chicago this weekend. But aside from that i found some how to videos that i would like to share off youtube, this is the kind of stuff I'm still leaning how to do so I hope u enjoy it as much as i do it's very fasinating:
