primo and winny question ....

hello, i have another question i could use some advice on. I have read on some sites that primobolan and winstrol can cause hairloss and do so alot, other sites i have read the opposite. I know first of all that your genetics regarding MPB is also a factor, but are they really bad for your hair, which would be a problemo for me. Any suggesstions would be helpfull , thanks!
