Blaze,
Ive not noticed any inflammation at the application site. Rosemary is supposedly pretty anti-inflammatory. Thats one of the oils in my little mix: Rosemary, Lavender, Cedarwood. Those are 3 of the 4 "classic" essential oils for hair (although other essential oils like chamomile have been used in the past).
The reason I didn't include thyme was that (from what Ive read) thyme has a suppressive effect on certain prostaglandins. Nizoral supposedly also has a suppressive effect on prostaglandins. I figured there would be no reason to inlcude it because I already use nizoral. Also, thyme has a pretty stout smell to it. Its used in a buncha' stuff though: mouthwash, insect repellant, etc.
I found something very interesting (to me anyway),

Black tea appears to inhibit alpha five reductase TYPE 1 pretty strongly. That kinda sucks because I was hoping that TYPE 2 was what it would inhibit. Rat liver microsomal alpha five reductase and LANcp prostate cancer cell lines were strongly inhibited by a couple of compounds in black tea (theaflavin 3 most strongly if I remember from skimming the article). I guess a guy could drink a glass or two of black tea a day, and sort of "buffer up" his finasteride to more dutasteride-like inhibition of alpha five reductase.
One other "finasteride-boosting" trick is to, according to TAGOHL (a guy who used to post at hairsite and one very well-read fellow) is to drink some grapefruit juice. Apparently the enzyme that metabolizes finasteride (I dont even remember that name....cytocrhome P450 34A or some such), is inhibited by grafefruit juice, making the finas active in the body longer. I understand that ketoconozale has some boosting effect on finasteride also, so the two work well together.
Im still doing finas and nizoral. My hair looks really good btw---especially good for someone getting to be middle age. Im just "nosy" about hair, thats why I pry around a bit when I get some time.
Have a great weekend
