Well I'm a little confused, if the last time you did this you had more sugar than oil, it would stand to reason it would have been MORE grainy not less. Did you use a different kind of sugar last time? A different oil perhaps? Did you scrub for a different amount of time, or use more or less water? There are so many variables it's really hard to say what might have gone wrong this time, but it could just be something as simple as your scalp was more irritated and therefore more sensitive. One thing I found that helps so as not to overdo it is once I'm done with the scrubbing portion, to not just wet but soak my hair so that the sugar dissolves a little and rinses out on it's own. THEN do the low-poo. You probably didn't do any damage necessarily, I would suggest rinsing a little more (and with warm water, that will dissolve the sugar faster) before beginning your low poo. Hope that helps!

My hair loves moisture!
currently mod-cg , using low-poo and not totally cone-free yet. I'll get there though!
