Another thing...Your body will let you know when it's time to increase or decrease. If you feel that the biotin is giving you negative side effects, then simply decrease the biotin and increase the water. If no side effects, then increase slowly until you find the amount you're comfortable with.
How long before I saw results? I'm not exactly sure. I just know the new growth came and it came quickly! /images/graemlins/laugh.gif Also, it came in coarser and thicker....so, personally, I prefer taking MSM along w. the biotin to help keep my texture manageable when I'm stretching my relaxers. Okay, I'll stop rambling now.... /images/graemlins/look.gif
