When i first joined the board i was taking them (because of another member, Macherieamour, who has gorgeous hair).
I finished the entire bottle, which lasted me maybe a few months or so....? They were cool. I didnt have any complaints, and my actually hair was doing well.
I ended up switching to another brand only because i was reading the backs of all the bottles at GNC, and another type of hair vitamin (i forgot which) had higher levels of Biotin, Silica, MSM, etc. So i figured i should switch to the brand with higher amounts of the "good stuff."
i have been taking mine since september of 06 and i saw great results. i still take them. I take them three times a day, but i also take a flinestone vit once a day, two 100 mg grape seed pills and two MSM 1000mg pills. so i can't say that my hair growth is just form the FB. but my hair is so much thicker and stronger than what it use to be. i got my touch up on dec 1st and i have about just a little over 2 inches. oh yeah i detox every now and then too. it took until december to start seeing results because i started them in september, so just give a little bit longer and see if you see any results.
i have this in my house but i dont take it. i used to take it sporadically but i was never consistent because i found it kinda of hard to swallow all those tablets at one time.
