thanks guys. I used to go 10-12 wks years ago before my old stylist started complaining and blaming the condtion of my hair on the fact that I was not comming in sooner. she always charged me extra if I had too much new growth and would sigh and rip thru my hair saying " $@(&* girl! you need to come in sooner!" she had me talked down to 6 wks and my hair was barely touching my shoulders due to her chops before I snapped out of it and found my first hairboard . 13 wks is the longest I've gone so far and that was only because it's easy to put into a ponytail or my two twists and go. I'm not sure if the growth is just my hair or the vitamins because I never paid attention to the growth rate before. My hair has always grown out of short cuts fast but broke off due to excessive heat, lack of washing and no oils, moisturizers or deep conditioning so I'm curious to see what it's going to look like with more time under my belt. I've only been doing this since Nov 02 and immediately began taking vitamins. whatever it is I hope it keeps up! I got my touch up 4/15 and I already feel thick headed in the roots! I'm really trying to pay attention but the new growth just kinda sneaks up on ya!
