Freezing donor hair for future balding

For someone paranoid about balding, but currently too poor to do anything about it aside from fin/min (oral+top) and derma-stamping, is there any way to somehow save donor area hair for the future? I worry that if financial security ever comes, it’ll be too late as far as my donor area is concerned. Any cheap solution to this? Do I just scalp myself and toss it in the freezer? (Kidding).

The donor area remains intact in most men throughout their early years until 60.  After 60, some men start losing their donor area hair. This is a normal process and nothing to worry about. Freezing hair for future use sounds extreme to me and not practical today.
