what is your opinion about finasteride?
Currently I can't completely shave my hair for important work-related reasons. I'll be able to do that in a year, but absolutely not now.
In the meanwhile, is a low fat high carb raw vegan diet sufficient to stop androgenic hairloss? Or is finasteride needed?
In other words, In your opinion, can the McDougall diet alone, completely stop the progression of male pattern baldness?
And can finasteride give an help? Or it is unnecessary? Or even dangerous?
Finasteride doesn't work... if it did, no one would be bald. Finasteride works by inhibiting the 5-alpha-reductase enzyme that converts free-testosterone into dihydrotestosterone (DHT). DHT stimulates sebum production. The solution (in my opinion) would be not to inhibit 5-alpha-reductase, but to lower free-testosterone (by increasing SHBG).
The McDougall diet completely halted my hairloss. And my hairloss was extremely rapid (I lost nearly 75% of my hair within 2-years)! I contribute this beneficial effect to an increase in SHBG, which increases with low intakes of fat and protein and high intakes of carbohydrate and fiber.
Also another side-note, I never really believed that DHT was the guilty hormone in the pathogenesis of baldness or prostate problems. I suspect that estrogen is the guilty hormone in regards to hair and prostate. There is pretty good evidence that estrogen is harmful to the prostate, but there is less evidence that estrogen is bad for the hair. However, I did read a few studies showing that estradiol caused the hair-follicles to enter (prematurely) into catagen-phase and reduced anagen (the growing) phase. More research needs to be done on estrogens effects of hair-growth/hair-cycles, but I have always believed that (excess) estrogen is bad for the hair (just like it is with the prostate or breast).
Perhaps an aromatase inhibitor would work better. The Pritikin-diet was shown to reduce estradiol by 50%, so maybe a starch-based diet, combined with an aromatase-inhibitor would work better for the hair. Finasteride, targets the wrong hormone in my opinion. Men need DHT for libido, sex-drive, erections, sperm, etc.
