Anadrol is an androgen, so it will aromitise and it will bind strongly with AR receptors in places that we might prefer to avoid. Those who have concerns about side effects will usually lean toward more anabolic compounds like deca, trenbolone, equipoise, winstrol, primo, masteron and anavar.
In reality, though, all steroids possess both androgenic and anabolic properties and all can cause undesireable side effects like hair loss.
There are, of course, some drugs and scalp treatments than can help with hair loss, but if you have MPB in your genetics, you will probably lose your hair anyway. Most of us experience a bit of receding of the hairline with steroids, but nothing too dramatic. Mine moved back maybe a half to 3/4ths inch over several decades of steroid use.
