Dee,
I know this is an old posting, so I hope you see this! Because I have the pretty much exact thing happening. My personal feeling is that the white flakes that come out are soap flakes from bar soaps that got stuck in there, or possibly (yuck!) dandruff flakes? I think I have heard of that, but then they're a little big to be dandruff. Anyway, when I poke into the dread or pull it apart a bit, it is very greasy and gross. They're fairly new, I started noticing this about 3-4 months in, and now it's 5 months - pretty much no more dreads! I tried using Neutrogena clarifying shampoo; the dreads pretty much all fell out, all my hair stuck together in a huge tangle, and what was left was the really glued-together parts at the top. It's been a downhill silde since then.
I used a 'deep cleanse' of recommended baking soda, lemon juice, and a few different e.o.'s, soak them for 30 minutes, do a rinse soak in clean water for 10 min or so, then ACV rinse, another rinse. Did this TWICE, all it accomplished was to turn my hair to straw and give me a hell of a rash on my hands! (you're supposed to massage dreads & scalp in this mixture, so my hands were in it, it stained all my clothes, towels, etc., I had on or near me at the time as well! I am going to have to somehow undo the top parts that are still stuck together (unless I can find out how to get it out!) and start all over. Very, very sad:(
So if you found something that worked, PLEASE let me know! Thank you so much!
