I have been CG for 3 months (using a low-poo for 2 and co-washing for 1) and I am running into some issues.

I have a "unwashed hair smell" even when I co-wash. My conditioner and leave-in are nearly scent-less.

I have also been having scalp problems. After day two or three of not co-washing, my scalp freaks out. I get really bad flaking, and I have one spot on the back of my head that always has a scab and bleeds if I scratch it. I had the exact same problem before I went cg. I have to keep my nails short so I can't scratch my scalp.

One thing I can think of that might give us a clue, I straightened my hair a week ago. I used a heat protectant that is all silicone and when I washed afterwards, I only used a low-poo.
