I think you worry too much regarding anti androgenetic effects. In a study I read that 3 mg oral S-Equol lower the DHT for like 15-20 % in men. How much contains a whole bottle? I think it was 11 mg. So in combination with the liposomes brotion will most likely reduce DHT nearly to 0 in blood.
If you think about the mechanism Brotion really could work. There is a study (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3032666/) which confirms that S-Equol has a high affinity for binding to DHT. If Brotzu managed to get the S-Equol on the right place in the hair follicle and to stay there long enough, this will bind to the DHT in the follicle. In addition to that DGLA will increase bloodflow.
Interesting study. From this paper:
"Finally, because grazing or other animals that produce high levels of S-equol naturally that are then consumed, such as meat products, by humans represents a source of equol as a secondary consumer. Evidence to support this last notion is shown in humans that consume high meat and fat diets display higher blood isoflavone/equol levels [10]."

CONCLUSIONS:
Serum genistein and daidzein concentrations were significantly associated with dietary intake of tofu, and slightly with intake of miso soup. Consumption of fat, meat, and coffee may be associated with equol production by intestinal microflora in this sample set.
I think those coffee drinking Carnivore dieters are on to something.
