Dr. Rassman,
Below is a study that links alcohol and testosterone levels- Does an increase in testosterone levels necessarily accelerate hair loss in men who are predisposed to lose their hair? Thank you-
Study abstract: Alcohol Clin Exp Res. 2003 Apr;27(4):682-5. Testosterone increases in men after a low dose of alcohol.
We have known for some time that alcohol is metabolized by the liver, as is testosterone. I can not connect the dots between the casual drinker and the hair loss victim.
