I have only been doing the CGM for 7 years, and had no idea I had curly hair before trying it. I thought I had stick straight hair and for years got a perm. My hair always was a little bit weird, even though straight, it could be frizzy. I had gone to a physical therapist because of frozen shoulder, and in talking she told me she was trying CGM. When I told her about my odd hair she suggested I try CGM. I have been a cosmetologist for years but never learned what to do for curly hair.
