Does THC (Tetrahydrocannabinol) have anything to do with the level of DHT and hairloss?

Smoking marijuana or THC and nothing to do with hair loss and DHT other than the "H' and the "T" in the acronym.  It is one letter removed from a semordnilap.

To the best of my knowledge there has not been any published scientific studies on THC, tetrahydrocannabinol, the chemical responsible for most of marijuana's psychological effects.Studies in mice have shown alterations in DHT levels. Studies in humans are lacking. REFERENCEDalterio et al . Effects of delta 9-THC on plasma hormone levels in female mice.Subst Alcohol Actions Misuse. 1983;4(5):339-45.

To my knowledge there is no connection between THC and hair loss. THC is the active ingredient in marijuana.
