It took me 6 months (Jan 06-June06). Right now I am grazing the top of the brastrap w/o straightening the ng. I figure when I relax in August I should be at the bottom of the brastrap. So I guess, 8 months to completely cover the brastrap from SL. My regimen basically consisted of washing with whatever Shampoo I have, conditioning with cholesterol mixed with castor oil and alittle ors hair mayo, and airdrying or rollersetting it. I wear my hair in a protective style everyday with a bun underneath with a stocking covering the bun (like the baggie method but with a stocking sock).
I take 5mg biotin (as of April 16), GNC UltraNourishHair (as of Feb) and 3000mg of MSM (as of Feb). I was using MN for about a month but stopped just because I wouldn't get home until late and would just wrap my hair and go straight to sleep. I'm not one of those anti-comb people so I feel that even if you comb your hair 2/3/4 times a day it will still grow because I comb it from the time I get home until the time I go to sleep and it still grew fine. I make sure that I put oil (castor, jojoba, olive) on my ends or hollywood beauty carrot oil this keeps my hair moisturized.
