Hi Dr. Rass. I am a every day visitor of this web site. You already mentioned about Viviscal in your site. But please go thru this site. Viviscal MAN
They have mentioned about something called “flax seed” which is a DHT blocker. Is it true?
Flax seed has not been proven to be a DHT blocker. There was a very small pilot study I read about from a few years back that consisted of 10 men that took 250mg of flax lignan extract in Thailand over the course of half a year, and that seems to be what people are basing this assumption on. Any hint of success, no matter how small, seems to be get blown out of proportion and becomes the next “ingredient of the day” in these hair products.
Sorry, but watching the hair of ten men over six months is not enough for me to be convinced. If there are more recent studies (preferably peer-reviewed), I’d love to see them.
