Do less androgenic roids such as anavar or you can do test only cycles and take 2.5mg of Proscar/Propecia a day. This will block most of the DHT conversion. DHT is what kills the hair follicles.
It is a fast acting Deca, I am currently using it and it converts about the same as regular deca and the good thing is if you experience any sides you can stop an it will be out of you asap instead of weeks like reg. deca.
