Everybody is different. Some people have little problem with test. Others say it makes them shed like a dog in the summer. Tren pretty much destroys everyone's hailrine, as does Winstrol (winny). EQ...some do...some don't. Deca...same way. Masteron...many say it is brutal on hair. Others have no problem.
I have seldom seen people mention Anavar (var) with hair loss though, and that's about it I guess. Almost everything bothers some folks and not others.
I have never used the dht blockers to save my hair...I just use a braun to make all of it match up.
