Are you losing hair gradually now? and it depends if your prone to hairloss. I use EQ only from late May to August with no hairloss. If you go EQ only at 600mgs you should be fine.
i ran it 400 and after about 9-10 weeks i noticed some, but it wasnt really that bad at all. and it stopped pretty qucikly after i came off. it was anything compared to the hell i experienced with winny.
