I called a pharmacist to day to ask about the drug interactions between MSM and anti-depressants. Anyway, he said that Dihydratestosterone (DHT) blockers, which are used to treat male-pattern baldness, will also increase the speed of hair growth. He said there has been scientific evidence of this happening. I looked on the internet for a naural DHT blocker and came across Saw Palmetto. Has anyone used this and what were your results?
