Limiting Hair loss on Havoc/ Tren X cycle

[DangerouStyle]

I am doing an Havoc/Tren-X cycle at the moment taking proprecia 1mg x 3 a day and using nizoral daily. Have also been putting nizoral 2% on and leaving on over night. I dont get male patern baldness do have a little receeding hair line pretty normal for my age (27).
Wondering what the best method for preventing hair loss is? My scalp has been pretty itchy lately 5 days in.
