I'm going to second Chewbaca on this: DON'T TAKE DHEA UNLESS YOU KNOW YOU NEED TO!
I have high DHEA and have had it for years (measured several times on hormone tests over the years). It's kind of funny in a way, my DHEA is sooo high (like 2-3x normal) that each time the technichian would write a comment saying something like "is patient taking DHEA" etc. My lutenizing hormone is a bit high and my DHT was high, and estrogen a bit low. So for me finasteride is a very good match, plenty of precursor for a bit of extra T and E2 and lower DHT. When I get around to check hormone levels again, I'll repost and bump this thread (if I remember).
Please keep in mind that DHEA is like a mother hormone. It is basically a precusor to every hormone the adrenals make (except the catecholamines and maybe a few others). Cortisol is included in that, btw, so DHEA could also raise cortisol levels leading to stress-like symptoms, which of course YOU DON'T WANT! Estrogen is also included!
Let me repost that abstract Chewbaca posted, it really is worth reading twice!
"Pitts RL. Serum elevation of dehydroepiandrosterone sulfate associated with male pattern baldness in young men. J Am Acad Dermatol 1987 Mar;16(3 Pt 1):571-3
Eighteen men aged 18 to 32 with rapidly progressive male pattern baldness had serum dehydroepiandrosterone sulfate and testosterone measured. Dehydroepiandrosterone sulfate levels were elevated in all patients, ranging from 340 to 730 micrograms/dl. The patients were otherwise healthy and serum testosterone levels were within normal limits. A control group of men of similar age without hair loss had lower dehydroepiandrosterone sulfate levels ranging from 124 to 300 micrograms/dl (p less than 0.005). The biochemistry of androgens, particularly dehydroepiandrosterone sulfate, suggests that adrenal hyperactivity may initiate alopecia in young men who are genetically susceptible."
