that's something bett1e that i was wondering about. for instance, my last touch up was in june. just recently my hair was sooo thick that i couldn't even get a comb thru it. i would comb it out, braid it and when i took the braids out i would have to comb it again by section. now,i'm used to my hair being like that, but it was thicker than usual...maybe the B5? anyway, i was trying to wait until nov/dec, but i couldn't do anything with it. i got a touch up last week and got it blown out and it's so thin looking only becuz that's how it is when freshly touched up. after a week or two it will hang with some body.
