Hi. This is just an update. I did as you said . I dissolved 2500mg of powder in 10ml of ethanol. This went well. However, when I added water to the alcohol solution, the powder reappeared. And because it was a fair amount of powder, it started to overflow. I think that the reason for why this happened is that the powder is not terribly soluble in water. In the end, I did it over and dissolved 300mg of powder in 30 ml of ethanol instead. This made for a 1% solution (10mg/ml). Yesterday, I applied it to my scalp for the first time. A dropper full of the solution (about 1ml) is plenty to spread over the area of my scalp before it evaporates. I’ll report here with any results I might get in the near future. Wish me luck.
Great job! You're the first person I've seen who went ahead and tried to replicate Papa & Kligman's study. I worry that an alcohol only solution may be a little drying and irritating to your scalp, so maybe you can add MCT oil instead of water for your next batch.
At any rate, it's all about finding a solution that works for you so you can stick with a daily application long term. The effects of hormones are very slow and cumulative, but if it becomes a habit like brushing your teeth, you might indeed be surprised at the benefits and results for your hair in several months to a year. Certainly, no significant cosmetic results should be expected in the near future though.
It may also have systemic effect to due to absorption, which is another benefit.
