Since you had hair loss prior to start the CG method, the problem might still be there. Have you gone to the doctor/dermatologist lately? I would start there first. Afterward, begin to stop using your usual products one at a time for one week, then evaluate your scalp's condition.
You might also have build-up and need to do a low-poo.
You could also try a hot oil treatment before.
I'm sure others will post as well.
