ladies i just want to say that biotin really does work. i've been taking this vitamin religiously for about a year. before taking biotin, my hair was breaking off really bad. everytime i washed it there would be clumps of hair in the shower afterwards. i washed my hair just last night and there was only a few strands of hair that came out. i also have stopped blowdrying my hair and i sit under the dryer. i use a wide tooth comb instead of a small toothed one. i also use to use the curling iron every single day to style my hair. now i only use the flat iron when i need it the most. my hair has become MUCH MUCH healthier from changing how i handled my hair in addition to taking biotin. my hair used to be right at my collar bone before i started this regimen, and now it is WELL past my shoulders!! who knew biotin could produce fantastic results? im sticking to this for life!
