DHEA is both an androgen and an estrogen, and supposedly a better agonist of ERb(good for hair) than ERalpha(responsible for gyno). still it might be problematic cause it can metabolize into DHT locally.DHEA and other adrenal androgens have a 15-30x lower binding affinity than DHT does for the Androgen Receptor.
Testosterone has a 2-3x lower affinity than DHT so its just as bad considering its 10-15x more abundant as an androgen.

Though it was found to be a partial agonist of the ERα with a maximal efficacy of 30–70%, the concentrations required for this degree of activation make it unlikely that the activity of DHEA at this receptor is physiologically meaningful. Remarkably however, DHEA acts as a full agonist of the ERβ with a maximal response similar to or actually slightly greater than that of estradiol, and its levels in circulation and local tissues in the human body are high enough to activate the receptor to the same degree as that seen with circulating estradiol levels at somewhat higher than their maximal, non-ovulatory concentrations; indeed, when combined with estradiol with both at levels equivalent to those of their physiological concentrations, overall activation of the ERβ was doubled. As such, it has been proposed that DHEA may be an important and potentially major endogenous estrogen in the body.[10][19]
