Having recently upgraded to a much more powerful machine, I can finally turn my attention to Flux! This is the Flux version of my Hairy Male Extreme series. The hair quality does seem better than before, but there are also some oddities, notably with odd ??????? on many images, so I'll need to go back through my image set: this is likely to be a first draft.

Strength can be more flexible here: I recommend higher a setting (e.g. 1.5 or even 2) for lighter hair colors. (Also, specifying red or auburn always seems to produce a ginger this time.)
